From convenient new ways of ticket purchasing, traffic alerts, and accessible forms of public & private transport to search for long-distance connections. In recent years mobility as a service rapidly gained popularity. Now, since we face huge global crises, accelerated by the dynamic society evolution, it might be a good moment to take charge of the growing service sector. With zero-emission declarations, new forms of green energy supplies, dynamic e-sector development, and top-down state regulations MaaS quickly evolve into eMaaS - 

. How to adapt and take advantage of still unexplored territories?

Several factors contributed to the success of mobility as a service. Since smartphones took over the world, the ways we consume goods changed. Development in the area of research and design of user-friendly solutions launched a space for new business models. With easy access to the net, growth of new transport options available, and car limits in city centers, owning particular properties became an unnecessary cost generator. MaaS became an innovative mobility concept, offering the possibility to get from A to B in an elastic, custom, on-demand, and straightforward way, often through a single interface.

MaaS owes its success to a user-centric focus and a different benefit package. As a service mobility allows passengers to choose the most suitable transportation dictated by their personal views and current circumstances. It could be price, rapidity, distance, weather conditions, or carbon footprint. Each user values a different available option. Powered by excellent frontend MaaS can provide various possibilities combining public transportation with solutions assured by the private sector. Supported by backend MaaS can deliver a huge dataset of transport preferences at different times of day and year. This will lead to a better understanding of user behavior and offered alternatives modeling.

With this growing concept of MaaS, the distributed transportation industry receives insight into the use of means of transport. Using a shared & integrated interface of transportation will lead to yet another value - a cheaper fee as “one journey” instead of paying a higher fee at each point. For vendors, this will mean shared fixed costs, a source of data for better business decisions, and new growth opportunities.

Electric mobility as a service ecosystem is a resultant of the earlier concepts solving common big city and mobility challenges, such as growing population, air pollution, increased pedestrianization, car-free zones, access to e-charging stations, and becoming environmentally friendly. Dictated by the transition to greener solutions there has been a rapid evolution of MaaS to eMaaS, which combines:

Shared, Electric Mobility Services (SEMS)

with the technical capability to design and develop a user-centric solution, market adaptation, and business skills to make the product rock in a sustainable way. eMaaS as a concept integrates the chopped up market of mobility options like e-car, e-bike, and ride-sharing, combining with public transport. With a major purpose to replace fossil-fuelled cars and increase the usage of zero-emission mobility assets.

In highly competitive markets shared services take the lead, providing value for each participant. Electric mobility as a service has a better chance to excel, also thanks to government actions and statements of the biggest players on the market. Reduction of exhaust emissions, maintenance, and development of new green energy sources, as well as e-form of transport, create new markets.

Changes caused by external factors will require top crafted technologies for a seamless run, thoughtful, engaging design, and easy compatibility for further development and maintenance. 

 delivered to the market will lay the foundations for prospective integrated systems. The duty of those in charge of e-development will be to skillfully select experienced partners supporting e-solutions. And lastly, designing solutions for future eMaaS integration demands not only tech but also a set of soft skills with a forward-looking approach.

We face yet another revolution. It’s e-revolution, that sets a challenge to deliver an innovative, e-solution so distinctive, that will give the advantage of creating exceptional value to users. And at the same time remaining easy to adapt on a large scale. Many factors determine the competitive advantage or even the success of e-mobility ventures. Government support programs, increased social awareness & approval, IT capabilities become key drivers on the road to create outstanding conditions for e-development.

Electric mobility as a service, with its all participants - suppliers, owners, and recipients - creates an extensive system of connected vessels, forming a powerful framework for e-business development.

Research explanation of e-Mobility as a Service

Before the digital revolution and user-centric approach, the concept of accessible, new forms of transportation was the future vision of what life could be like. With the rapid growth of technology, mobile devices, enhanced battery capacities, wide Internet connection, investments in new unexplored forms of service delivery, and quick social adaptation in the last ten years we have witnessed a great transformation.

Raising enthusiasm boosted consumption and proved that rapid adaptation is possible and widely accepted. New economic models have begun to take into account sharing concepts and value the tangible benefits of such solutions. In a sharing economy, not used assets such as parked cars and extra bedrooms can be rented out. We transferred from owning to renting. And this concept widely approved first by Uber users moved to other transport areas offering new possibilities. In the Alternative Journal article, 

 , Ray Tumulty (2014) the sharing economy is described as a clearly urban phenomenon. To achieve economies of scale for shared economy services satisfactory population density is required. Moreover, these services are seen as an extra option, not a replacement for traditional sectors. Ridesharing is used along with public transportation in cities.

With the growing success of rented items and services, new forms of transportation options come to the market. The mobility concept grew to form a comprehensive ecosystem offering numerous moving variants, such as city bikes, electric scooters, car rides, ticket purchasing options, city traffic monitoring, planning the most convenient route, parking options, integrated payments, and available charging options for ‘e’ users. All available in real-time from the mobile app on one’s phone. This progress developed the term 

 , which covers a wide range of mobility services available on the market, and its integral part becomes a shared economy providing extra value for participants.

On a high-level, the MaaS ecosystem includes transport infrastructure, transportation services, transport information, and payment services. Within the ecosystem, the common objective is the delivery of a seamless mobility experience and transportation network improvement by utilizing the benefits of each service - public and private. Besides, other participants such as local authorities or data administration companies can collaborate to smooth the operation of the services and improve their profitability.

One of the MaaS ecosystem examples was presented by the Siemens Mobility Division in 2016 for Tampere City, Finland. The ecosystem is build of 4 main elements: service providers; a business-to-business (B2B) platform; mobility retailers; and the users. The intention of the project was to unite the existing and upcoming transport services with the operations of the local paratransit services.

A similar approach on a high level was presented by König project ‘Mobility As A Service for Linking Europe’. Four different levels define the public and regulatory level, the transport and logistics service providers level, the mobility service level, and the end-user level. On the basis of similar concepts and definitions, a framework for Mobility as a service was developed.

From a business perspective, MaaS is described by Kamargianni and Matyas in the paper ‘The Business Ecosystem of Mobility-as-a-Service’[1](2017) as ‘the wider network of enterprises that influences how a dominant company, in this case, the MaaS provider, creates and capture value’.

To support theoretical premises on shared mobility, a survey conducted by McKinsey&Company (2017) provides some insight into the consumer’s opinion on ride-hailing and car-sharing. Respondents were asked how their usage of ride-hailing and car-sharing services will change within the next two years. In both cases, over 60% responded that it will increase or increase significantly. Shared mobility is mostly favored in urban areas, but seems to be less attractive for running errands or multi-stop shopping trips.

We are an integral part of the next global transformation, where alternative fuels and green energy takes charge. The concept explained above has been extended with ‘e’ - a possibility to travel in an eco-friendly way, where ‘e’ stands for electric solutions.

Electric Mobility as a service combines Mobility as a Service (MaaS), Electric Mobility Systems (EMS), and Shared Electric Mobility Services (SEMS) [2]. As a concept eMaaS operates upon MaaS, where the last one became one of the complementary components. With that defined, all MaaS participants become, as a consequence, eMaaS attendees. Providing they offer electric mobility solutions.

Electric Mobility System (EMS) covers technologies (batteries, charging technologies, drivetrains, and EVs), infrastructure (physical and organizational of charging stations, electricity grid, information and communication technology), and users (manufacturers, suppliers, end-users, service providers, governments, and agents).

Shared Electric Mobility Services’ (SEMS) applies to a new economy implementation, where instead of ownership there is an on-a-need basis share connected by the technology with users and providers. SEMS replies to the environmental, social, financial, and transportation-related benefits that had already been correlated to emobility and shared mobility practice connecting both. Five business approaches are proposed:

Membership-based (e.g. e-bike sharing, e-car sharing, e-ridesharing, e-ride hailing, e-scooter sharing, e-bus sharing),

Peer-to-Peer(e.g. e-car sharing, e-bike sharing, e-scooter sharing),

Non-membership-based (e.g. e-car rental, elimousine rental),

For-hire (e.g. e-car/bike/scooter sharing, e-ridesharing e-carpooling),

Mass transit systems (e.g. e-Public Transport, airport autonomous shuttles).

As a part of a wider concept, combined with two other components MaaS & EMS, together provides multiple eco-friendly transportation possibilities. Successful implementation of such a concept requires multi-level support, well-designed system architecture, and an extensive network in public structures.

The user-centric approach will always be foreground. It applies to the development of the widely recognized concept of e-mobility as a service. From accessible payment methods for single ticket purchasing, subscriptions, to well-developed charging networks and various means of transport access. At each stage of the proposition should be declared value.

We are still in the early stages of what could be called e-Mobility as a service. Most customer journeys are under development, and achieving overall flow is still in its infancy. There is a lot of research to be done, but there is room for the general necessary approaches. Each of the participants, in order to achieve success and remain successful in this growing market, should remember the needs and behavior of the end-customers - have in mind that ½ users are likely to bail on service or purchase because of a single bad experience.

One of the success factors will be easy, integrated payments, giving preferable plan or demand models.

Plan option: Participants pay a monthly fee befitted to their transportation needs. Such plans can be split into an urban commuter, family, business, and casual. They include all public transport options as well as taxi, rideshare, carshare, etc, to cover individual needs.

Pay on-demand alternative: Paid as traveled with the difference that the payment is for the whole trip in one go independent of transport means. So if in need to take the train, bus, and then taxi on one trip, it’s all included in one, joint payment, executed automatically via smartphone.

Technology changed the way people consume goods and services. With handy devices, ¾ of consumers expect the service within five minutes from the initial contact. The same share wants ‘the simple experience’. From all players, customers expect immediate action, personalization, and convenience. This requires a broader view focusing on journeys, not only touchpoints, which will become a framework for further expansion.

When it comes to user preferences, whether it applies to simple app development or complex system design, it’s been always about developing a complete value proposition that answers the needs of the user and delivers a convenient solution. With a unique experience, trust, and the right technology that supports EV drivers, e-mobility participants can succeed.

E-mobility revolution driven by technology

The entire development of various e-mobility solutions is powered by rapid smartphone penetration. Since the handy device gives us access to countless possibilities, the way people consume goods and services changed. As a matter of fact, smartphones enable and will be a core factor for rapid growth in eMaaS concepts and Smart City solutions. Among the technologies being developed electric cars, route optimization resolutions, car-to-car communication will change the way we commute itself.

In search of efficiency, communication will become a smart blend of technology, infrastructure, and users. Electromobility and autonomous driving development are considered to be the catalyst for changes taking place in urban consumption. E-mobility secures eco-friendly and efficient vehicles on the roads. E-driving became globally a high priority. Climate change, oil shortage (Statistical Review of World Energy 2017 estimates that the world’s currently known oil reserves will last +/- 50 years given current levels of consumption), and air pollution brought forward the development of green solutions. As long as the power is received from renewable sources e-cars and hybrids represent the most efficient and environmentally friendly ways of driving.

Core components of business and technology are connectivity solutions, integrating components, user interface, infrastructure development, battery technology, driving software and product design, high accuracy maps, secure solutions, data storage and processing, between-vehicle communication. Well-developed services build upon a user-centric approach, providing integrated, smart, handy assistance.

According to a survey conducted by Otonomo [3] among the citizens of European countries, most car owners think that manufacturers collect their data for product improvement or development, advertising, segmentation driver types, and learning more about habits, reliability, usage, or preventative maintenance.

Consumers declare that they would love to have access to data generated by their cars. Three-quarters of survey respondents showed an interest in receiving data held by OEMs (Original Equipment Manufacturer) more than twice a month and nearly 50% of respondents would love to receive data frequently (even up to once a day).

Additional information consumers would love to receive are car alerting about dangerous conditions ahead (72%), early necessary maintenance and repairs detection (59%), car knowing the traffic and suggesting an alternative route (59%), an app that allows deliveries to be made to your car’s trunk (51%), car suggesting nearby, available parking (48%) and software that allows having fuel delivered (46%). So, not only drivers do not mind gathering information but also would appreciate receiving feedback and insights.

One of the widely appreciated models by the 2 billion consumer segment is car sharing [4]. Generation Y (born between 1977 and 1994) desires connectivity and convenience. Having numerous transportation options Millennials are more likely to choose on-demand services instead of ownership. New mobility service providers connect seamlessly drivers with passengers (carpooling, taxi) or passengers to cars (car-sharing).

The latter one, powered by technology and finest logistics, offers great value for one-way trips, as well as planned round-routes. Without bearing the cost and effort of car ownership Millennials can get a unique feeling of driving. The sharing economy provides favorite conditions with a blend of technology and service without exhausting the possibilities. Car sharing leads in big cities where scale effect is easy to achieve by, among other things, cost reduction and lifestyle changes. To confirm this, in 2019 Global Car Sharing market value was 2.5B USD (Global Growth Trends) and is expected to grow up to 9B USD globally in the next 6 years.

Car sharing quickly became outstanding among other mobility services thanks to a wide range of business models applied, offering different experiences and pricing systems. One of the success factors is the flexibility provided with usage areas and distances to be traveled. On the basis of a well-known car rental model, three concepts were developed: 

free-floating, stationary, and peer-to-peer car sharing

. The latter business model, where individuals can offer their car rental to private users via a platform, successfully conquered the French market. P2P offers long-distance transportation mode for longer routes and became an alternative for short-term rental or carpooling.

Allows to pick up the vehicle and return anywhere within a certain area, operates mostly in the city centers, usually providing smaller cars, in cooperation with local authorities providing dedicated parking spaces. When it comes to car sharing in a free-floating model, many providers see the investment as a strategic step, as a new promotional channel, and direct access to customers’ insights.

Free-floating business model success factors are:

location (high density to reach the scale),

cooperation with local authorities or private sector (e.g. in Poland IKEA offered dedicated parking spaces for Traficar as a part of yet another transport service), and

convenience (the majority of the fleet consists of city driving cars).

E.g. In France free-floating cars, according to a study by Les Échos newspaper, represent 26% of carsharing vehicles. Among these, 44% are electric. Free-floating electric car-sharing in Paris emerged in late 2018 with the following launches of Free2Move, Car2Go, and Zity. Over 1,400 electric vehicles were deployed across the French capital by these companies.

What is interesting, on the basis of free-floating, other urban transportations are offered, such as electric scooters, city bikes, e-bikes, and mopeds.

The oldest model with the start and endpoint at the same station, dedicated to round routes. With different needs, the lack of flexibility is being replaced with a wide fleet variety. Stationary car providers usually operate in smaller cities and rural regions. What is interesting, they do not operate globally (with one exception Flinkster by Deutsche Bahn Rent). Success is linked to extensive local market knowledge and customers' needs understanding. They often rely on other providers' cooperation, creating broader networks offering free-floating alike experience on a long-distance driving.

Key success factors in this oldest, but nourished with fine technology, are:

location in medium-sized cities and rural areas

availability (often located by the airports or train stations)

pricing based on hourly rates or distance

wide fleet selection for various purposes

Some global players see the opportunity in free-floating, e.g. in 2011 as a joint venture of BMW and Sixt established DriveNow, other invest in stationary car sharing, e.g. Volkswagen by investing took over 60% of Greenwheels in 2013.

In February 2020, Daimler AG and BMW announced yet another car-sharing services partnership under a new brand, 

 . By merging Car2Go and DriveNow, 'ShareNow’ became a market leader, being present in 20 European cities with a fleet of over 20 000 vehicles. ShareNow actually is a mix of both concepts mentioned - a combination of stationary car-sharing and free-floating. Various paths of car sharing are being tested, thanks to a broad range of possibilities offered by technology. In October 2020, Toyota launched its new car-sharing service to provide a wide range of mobility services for short-term use on the Japanese market. Based on these few examples we can only expect new services to be tested and developed. Combining traditional concepts with modern technologies may soon influence consumer behavior, look at certain aspects of e-mobility as well as create new businesses. Hence, the theoretical aspects of emobility presented earlier reflect the real changes.

P2P seems to be a niche market, is the only concept where private individuals offer their own vehicles. The exchange takes place via a dedicated platform, offering insurance and telematic equipment to provide smooth access. The car must be returned the same day within the pick-up area and used for round trips. The pricing provides a great alternative to car rentals or stationary car sharing. A decentralized fleet offers a wide range of brands and models.

Being called a niche, drivy initially operated in the French market, quickly converted to 

 , and operates now in the UK, Germany, Austria, France, Spain, Belgium, and the USA. Undoubtedly, the P2P car-sharing success happened due to most favored factors among consumers, similar to Airbnb, unique value combined with technology resulting in a great alternative to other, more traditional services. A prime technology - the platform and telematics ease the use. Thanks to one of the shared economy principles, P2P car sharing offers a diverse, accessible network, quickly spreading to new markets, providing value to each participant. Moreover, the P2P concept getaround is empowered by well-designed insurance policies to cover lending concerns.

The increasing traffic congestion in urban districts doubled with overloaded public transport facilities is boosting the car-sharing market revenue. The emergence of electric vehicles in public areas will be accelerating in order to reduce gas emissions. Attracted by extra benefits, such as incentives, 

 , parking spaces in exclusive, centered areas, providers will enhance the electric cars fleet.

Although the concept of car sharing is enthusiastically acclaimed this doesn’t mean that ‘ownership’ will go into a niche. Today’s consumer profile on the EV market is evolving from early adopters to mass adoption. According to a survey conducted by Accenture [5] in 2019 in China, Europe, and the US, respondents declared that they expect to own a car in the future. When asked if they would resign from possessing in favor of services, nearly 50% would consider giving up ownership in favor of integrated mobility services. What is more interesting in Europe, 55% of premium car owners and 41% of non-premium owners are more likely to switch.

One more factor may place a sharing idea further afield. A 

 conducted in June 2020 by cars.com showed that 70% of respondents declared the coronavirus has led to a reduction in commuting, and 49% reported their commute has been greatly reduced or become nonexistent. 58% who previously commuted via a public vehicle - carpool, taxi, ride-share, or bus - 44% of them said they’ve had a reduced the need, and 15% reported having no need to commute. 38% stated they usually rely on a bus to commute to work, 42% declared they’re riding less and 15% said they aren’t riding the bus at all. More than 55% of respondents actively consider buying or leasing a car, and 7% actually acquired a vehicle due to the pandemic. What is more, the pandemic became a reason to consider buying a car for 20% of respondents. The decisions were strictly dictated by the concerns about public transportation and the sanitation of ride-sharing vehicles.

Electric Vehicle market is going mainstream

Although the term electromobility or e-mobility applies to all means of transport powered by electric energy such as e-bikes or pedelecs, electric motorbikes, e-buses, and e-trucks we focused on e-cars. Several factors contributed to rapid EV penetration in Europe. From governmental declaration to achieve zero-emission goals by 2050, research and development, a wide range of possibilities to scale up fast provided by technology to raising environmental awareness. In this paper, we provide all the necessary information but starting from the beginning. Among the available options for electric cars, we have:

Hybrids (HEV) - Hybrid contains both an electric and combustion engine. The battery is charged via the engine while driving and stores the braking energy at the same time.

Plug-in Hybrid (PHEV) - The battery stores the braking energy in plug-in hybrids. Plus the car can be charged via the grid.

Range Extended Electric Vehicle (REEV) - is efficiently an all-electric vehicle, with all the motive power provided by an electric motor, but with a small internal combustion engine present to generate additional electric power. I.e. it might be viewed as a series hybrid with a much larger battery, namely, 10–20 kWh;

Battery Electric Vehicle (EV or BEV) - The vehicle is fully powered by the battery charged via the grid.

Two-way charging technology. When EV is charged, AC (Alternating Current) from the grid is converted to DC (Direct Current) power. Possible to be implemented by the EV’s owner or charger’s converter. What is more, this technology allows the energy stored in batteries to powerhouse/external load (V2H) or send it back to the grid (V2G).

Nothing new here, but some may not know that EVs wireless charging is possible. The vehicle’s battery can be empowered wirelessly by parking the car on a spot with a charger on the ground. Just like wireless phone chargers. Although, the amount of exchanged energy in these wireless systems notably outpaces a wireless cell phone charger, seems like a great challenge for startups developing them. These innovations must be 100% safe, certified solutions. One of the examples of a park & charge solution is Canadian startup ELIX.

A fully charged car in 20-60 minutes is possible, although the ultimate goal is to fully charge a vehicle in less than 10 minutes. Just like gasoline at the petrol station. For example, GBatteries is working on advanced super-fast charging technology without the influence of battery life. The pioneers like Tesla, ABB, ChargePoint, EVbox, and other OEMs and networks offer fast-charging stations. Among other obstacles associated with handling the huge power demanded, if not done correctly, fast charging can lead to faster battery degradation.

Similarly, just like power banks for mobile phones, startups are building portable charging systems for EVs. For example, SparkCharge offers stackable batteries that can deliver up to 60-75 miles per full stack and work together to deliver the exact amount of range needed.

Since the most comfortable ways of charging EV is still overnight, for those who don’t have a garage or access to any charging station nearby, British startup ZUMO offers a solution for those who own or want to own an EV but lack a driveway. They pick up the car, bring it to a charging station, and bring it back to the owner the following morning, fully charged and ready to go solving the issue of charging in big cities.

With the technology that uses copper coils embedded under roads and connected to the electricity grid, along with receivers installed under vehicles the dynamic charging is being in deployment in Sweden for E-bus with a Super- Capacitor battery and a heavy Duty E-Truck with a Li-Ion battery. Yet another EV charging resolution proposed by Electreon. Similar projects also take place in Germany and Israel. Recently Italy joined the testing phase with a one-kilometer examination section of the A35 highway between Brescia and Milan. If the pilot becomes successful the entire 62-kilometer (both ways will be approx. 150 km) length of the A35 freeway will follow.

This allows to intelligently manage EV charging by connecting it to the grid. Smart charging is all about connecting charging points with users and operators. Each time an EV is plugged in, the charging station sends information (i.e. charging time, speed, etc.) via Wi-Fi or Bluetooth to i.e. a centralized cloud-based management platform. Smart charging can provide additional data such as information about the local grid’s capacity and how energy is currently being used at the charging site (house, office building, supermarket, etc.). The gathered data is being analyzed and visualized in real-time by the software behind the platform. With smart charging, charging operators can control and regulate energy usage easily and remotely through one platform, or mobile application. EV owners can benefit by using a mobile app to monitor and pay for their charging sessions from anywhere, any time. Smart charging offers power-sharing, dynamic power-sharing, and power boost. It also allows vehicle owners, businesses, and network operators to control how much energy EVs are taking from the grid and when. For example, Wallbox offers such a solution. A wall-mounted box can be installed in a private garage or a condominium or company parking lot. Wallbox is being recommended by several electric vehicle manufacturers, e.g. Renault.

With the most common charging option on the market comes three main types of EV charging: rapid, fast, and slow. These represent the power outputs, and hence charging speeds, available to charge an EV. Each charging device type has an associated set of connectors that are designed for low- or high-power use, and for either AC or DC charging.

 enable to recharge an EV up to 80% in 20 min to 1 hour, depending on the battery capacity. With 50 kW DC charging is possible on one of two connector types using either the CHAdeMO or CCS charging standards, 43 kW AC charging on one connector - Type 2 standard, 100+ kW DC ultra-rapid charging is possible on one of two connector types: CCS or CHAdeMO. All rapid units have tethered cables.

The growing concept of e-Mobility as a Service

Trust is a must. Especially in running e-mobility business. Here is why.

Having spent over two years developing various components for one of our e-mobility partners I want to share some insights on how to cope with challenges, what to expect from IT partners when developing e-mobility components and how testing various approaches can lead you to some of the breakthroughs.

Before you start, whether you are an aspiring Charge Point Operator or e-Mobility Service Provider, here you can find some valid questions, worth answering: Is there a ready-to-apply business model for long-term prosperity in the e-mobility segment? What return could be expected for now and in the future? What in-house skills are needed and what other partners require for revenue growth? Could technology and data analytics enable the business to provide ‘smart’ solutions? If yes, how? Where is the industry heading to and what are long-term goals?

What we face now, in the era of uncertainty, is another ‘revolution’ dictated by the exhaustion of fossil fuel resources, environmental pollution, and hence the transition to green energy. The EV market, especially in Europe, is growing fast and we face the increasing need for accessible, charging infrastructure, green energy demand, and a change in consumers’ behavior. With a rapidly rising demand for investment, we have a common ground - require a change in consumer habits. Even with rapid-charging technology (50kW+), charge time takes 20 to 30 minutes to reach 80% of battery capacity. But a well-known benchmark - refueling petrol or diesel experience is still out of reach. It seems that there is still a long way to go to achieve full flow, yet without constant development and improvement of the accessible infrastructure, we won't be able to move forward. Providing consumers the multitasking opportunity for rapid EV charging, whether combined with retail sites or bespoke charging 'lounges', together with a shift from a top-up (as opposed to refuel) mentality will be necessary to aid mass adoption.

Below you can find some thoughts on obstacles you may find while developing an e-mobility platform, what to take into consideration while creating a workflow, and what to expect when you start your venture into unexplored areas.

Creating a valid data model from the beginning will be a huge time-saver

Late changes to the data model are time-consuming. MVP or initial variants of the software cover all the basics. When the system does not require a sophisticated model of the charging infrastructure it may be enough to shape the whole charge point as a flat structure. Upon this simple model, more features can be built, till your range grows, and a need to open the platform using some open standard comes up. This action requires mapping development between the internal model and the one introduced by the standard. If the existing model does not support concepts (e.g. Location and Evse) and does not follow general standards, when it comes to the format of IDs, it might demand plenty of work to perform the efficient mapping.

While working for one of our partners, mapping their existing codebase to make it available for open standards, for a team of developers took several months. In fact, if the model would match the standard from the beginning, the integration would require just a simple action, and full integration would be possible within a few weeks.

Lesson learned from this experience: The time for full integration can be significantly boosted (reducing a few months of integration to a few weeks) thanks to the implementation of a ready-made code sequence linking the standard and the platform. Once the standard is properly applied, further action will become smooth and easy.

Creating an efficient architecture of the system from the start prevents many bad decisions

Some aspects of system architecture are specific to the domain. For example:

deciding which processes are synchronous and which are asynchronous

the decision of whether or not some data must be immutable

Understanding incremental improvements and having in mind that not every single aspect can be predicted is crucial. However, knowing the domain certain aspects can be included early in the design process.

Lesson learned from this experience: General concepts, but taking into account these limitations from the very beginning helps to avoid making wrong decisions when designing and developing the e-mobility platform.

Knowing the details of adopted standards is the shortest way to success

OCPI is defined as an open standard. In theory, everyone ought to introduce this standard in the same way.

Lesson learned from this experience: OCPI is not always the norm. Hub Gireve, for example, extends this standard. Some concepts exist and are not part of the OCPI documentation. Some OCPI partners require a certain sequence of specific actions that are actually not part of the standard. It is worth knowing this upfront when designing the CPO/eMSP end system.

The domain knowledge provides you with solving individual cases

Having the domain knowledge within the development team allows participating in specific direct business conversations about e-mobility. Becoming familiar with general concepts, e-mobility background (CPO, eMSP/EMP, EVSE, eMI3 ID, OCPI, OICP, OCPP), ubiquitous language, different market approaches (public/private/fleet charge points), we can immediately proceed directly with the specific business issues that are to be done, rather than technical details (as a reliable tech partner we already know them).

Lesson learned from this experience: We have learned that getting to know a specific area takes time, but once explored, it allows us to catch common parts. The observations turned into concrete e-mobility solutions, thus are an improvement for the future. Combining domain knowledge with high-level technical skills provides quick integration and unlocks business processes.

It might sound a bit cliche, but without having great, skilled, and curious minds on board I cannot say that the progress we witnessed would be possible.

Lesson learned from this experience: In addition to specific technical skills, in such projects where many questions are asked and actions require a constant search for efficient e-mobility solutions, the spirit of a truly matched team of individuals appears.

Knowing the challenges from the scratch, making observations, and drawing conclusions for the future on how we could boost integration, we have spent a couple of weeks developing ready-to-integrate components for Open Standards. Full e-roaming is possible to achieve faster.

 – The component being an Anti Corruption Layer between any CPO/eMSP system and any OCPI partner (hub like Gireve and p2p partners like other CPOs and eMSPs). The component has the whole OCPI registration process modeled with the token-based security mechanism. It maps all OCPI calls to the internal backend API (this part is open for modification for the concrete backend system).

 – The component and test suite allowing to execute e2e tests of the platform using OCPI protocol. Testing OCPI allows a complete test of bidirectional processes that are part of OCPI.

 – The component is an OCPP server being able to connect to the charge point using OCPP (2.0.1) protocol. It is a proxy for the whole communication between the charge point and the CPO backend system.

 – The component is a software Charge Point that allows e2e testing and monitoring of the CPO platform.

Soon our work will be done with this extra e-mobility component:

e-Mobility partnership – lessons worth to know

Open standards can be a game changer for both eMSP's and CPO's. Here is why.

The initial stages of technologies lead to various types of solutions addressing the same problem. Each company develops a different approach. At the beginning of the XXth century, when commercial electricity had come to the mainstream, multiple energy producers offered power supply with miscellaneous frequencies and voltages. As time passed, governments began to impose certain standards on suppliers. This standard-setting led to the joint effort to create the first power grid.

From the first power plant to the moment when all energy providers linked to the same network, decades passed. This was only possible because they took a mutual direction.

 - literally and figuratively. With global warming, exhaustion of solid fuel resources, and lifestyle changes, companies face the challenge of how to provide accessible new charging forms of green power.

Now, as the e-mobility era is here, we are on the same page, like we were at the very beginning of the XXth century. We already have plenty of providers: eMobility Service Providers (eMSP) and Charge Point Operators (CPO) - two substantial sides of the e-Mobility world. One of the main challenges ahead of this market is to deliver the best user experience, at possible minimum resources use. As usual, user experience is a matter of well-designed apps, customer support, and simplicity itself. But there is an additional fact. End-users need to be able to charge cars at any charging station without being concerned about accessibility. The issue is - having the contract signed with the Charge Point Operators recharging point service. How to achieve this? Partners must take the same course, and this is where the standards start to play a major role. There are two possibilities: Open Charge Point Interfaces or Open Intercharge Protocols. What are the benefits?

The main goal of the Open Charge Point Interface (OCPI) is to allow electric vehicle drivers to charge their cars at any station. OCPI defines a set of modules that cover most cases the driver may need. There are two technical modules that are used to establish connectivity between two platforms using OCPI: Credentials module and Versions module. Other modules are strongly related to real-life use cases. These would be:

Locations - module responsible for sharing information about the Charge Points, like address, geolocation, real-time data about the current status, electrical parameters.

Sessions & Commands - module allows the end-user to start the charging session and be informed about the current status of the charging session.

OCPI is an open standard, and what may be very important for the adopters - it’s very flexible. For instance, CPOs (Charge Point Operators) may implement only the Locations module (apart from two technical mandatory modules) when only sharing Point Of Interest data. With no necessary exposing the eRoaming functionality. But the ultimate goal for many CPOs is to allow end-users to charge their car. In that case, many more modules need to be implemented (Sessions, Commands, CDRs). Some others are optional, even for the eRoaming (Tokens, Tariffs), and that depends on the agreement between certain allies. It’s in terms of how financial flow and security is modeled.

The biggest advantage of having OCPI implemented is that it’s almost a one-time investment. The initial effort is significant, as it might be challenging to transfer internal models and processes to the OCPI. But once it’s done for a partner, it opens the company for quick and cost-effective integration with a lot of other associates.

A bit different concept is proposed by the Berlin-based innovative company - Hubject. Hubject developed its own API (OICP) covering almost the same cases as OCPI. There is one extra. Hubject also acts as a hub. It connects CPOs and eMSPs. Once a company is connected to the Hubject platform, it becomes open for integration with any other comrade being already assigned. That’s a huge advantage because the integration is done once, with one platform, and of course it becomes profitable when it comes to an alliance with multiple partners.

Yet another advantage of the Open Intercharge Protocol is that it’s quite easy to implement. Like with most protocols, the main challenge is to synchronize our internal models with the standard one. What is comforting with OICP - there is not too much to implement. It depends on the level of integration we want to achieve, but it’s enough to implement about 5 HTTP calls to expose eRoaming through the Hubject platform.

Having in mind multiple historical examples, it may be difficult to be a part of a developed market without following widely adopted standards. Initially, it may need some additional effort. But when the standard is implemented, our platform becomes open for the whole market 

. Without it, we would need to spend weeks or months doing the integration with each partner separately.
