OICP is developed and owned by Hubject (a joint venture of the BMW Group, Bosch, Daimler, EnBW, Innogy, Siemens and the Volkswagen Group). Initiated in 2012, Hubject is now the largest pool of charging stations. Via Intercharge they provide standardized access to eMobility infrastructure through their dedicated platform. They also advise on how to best implement Plug&Charge with ISO15118 standard.

Hubject has created the largest global charging network for electric vehicles by linking charging networks from various providers. This network includes over 500,000 connected charging stations and has partnered with more than 1,250 B2B companies in 52 countries spanning four continents. In addition to serving as a roaming platform, Hubject provides technical connections and contractual support for eRoaming in the electric vehicle charging industry.

Open InterCharge Protocol - the structure

Open InterCharge Protocol (OICP) was developed in 2012. Hubject proclaims that OICP is “the most widely implemented communication standard between European eMSP and CPO systems”.

The general structure of the OICP is divided into two parts - for the eMobility Service Providers and Charge Point Operators, nevertheless, the product offer is constantly being developed.

Charge Point Operators (CPOs) have the opportunity to benefit from the SHARE solution. This solution enables customers who have a contract with an eMobility Service Provider (EMSP) to use the CPO's charging infrastructure for vehicle charging through eRoaming. To make this possible, CPOs must establish a connection with the HBS (Hubject Brokering System) eRoaming platform. The HBS operates as an open marketplace for eMobility, fostering an interconnected network that benefits all participants in the end.

eMobility Service Providers can benefit from the CONNECT solution, which enables them to provide EV drivers with access to public charging infrastructure across international borders. Through the intercharge network, eMSPs' customers can easily identify available charging points using the recognizable compatibility symbol, the intercharge logo. By connecting to the intercharge network, eMSPs' customers gain the ability to utilize all charging points offered by participating Charge Point Operators through eRoaming. Similarly to CPOs, eMSPs also need to connect to the HBS in order to achieve that.


Additionally, for eMSPs, there are two distinct ways to be connected to the Hubject platform:

 has no real-time connection for authorization to the Hubject platform.

 is fully connected to the Hubject platform via a real-time interface.


The protocol is readily accessible to the public without any associated fees or mandatory registration. Since May 2019, OICP has transitioned into an open-source protocol, available free of charge, and can be obtained from Hubject's website and open-source code distribution platforms. The primary goal is to involve a broader range of stakeholders in the ongoing development of OICP. This protocol is released under the Creative Commons Attribution-ShareAlike 4.0 International License, allowing for straightforward distribution and sharing under the same terms. Furthermore, Hubject provides Hubject-compatibility certification for those seeking to ensure compatibility with their systems.

Open InterCharge Protocol - versions and technical specification

OICP follows a distinct release policy where each service is versioned separately and independently from the OICP version itself. For instance, there could be an e-roaming authorization service in version 2.1 while the OICP version is at 2.2 concurrently. With each new OICP release version, a corresponding service version specification is introduced, and these are the supported services. Hubject commits to providing support for each new OICP release version for a minimum of two years. Lastly, any new implementations should be carried out using the latest available OICP version to ensure compatibility and adherence to the most up-to-date standards.

The most recent version is the OICP 2.3. 

The newest update of the protocol follows market requirements - improves the POI quality in an upscaling market, calibration law compatibility, data process performance, and offers higher transparency on the different charging use cases. Additionally, Hubject offers helpful and relevant for CPOs set of remote testing functionalities, for complex examination of various use cases.

OICP is formed on SOAP (Simple Object Access Protocol) and uses an object-based approach. It’s a real-time protocol that also offers asynchronous operations. Although a back-up database is provided, Hubject doesn’t actively support downloads to the charging station. The platform maintains a record of the transaction data.


The OICP protocol documentation establishes market roles as follows:

wants to charge an EV at a charge point/charge station, and has an agreement with the eMSP.

 wants to enable EV owners the access the charge points. In most cases, the eMSP has a valid contract and transfers information with the Charge Point Operator via Hubject’s platform. Hubject offers connection via eMSP aggregator, which enables communication with the platform. This means several eMSPs can integrate via an eMSP aggregator, hence, the sub-partners do not need to associate with Hubject.

 manages a charge point. The operator has a signed contract and exchanges information via Hubject’s platform. Like eMSPs, several CPOs can integrate via a CPO aggregator. Appropriately the sub-partners do not need to register with Hubject, because the communication with Hubject is done via the CPO aggregator.

 facilitates communication between eMSPs and CPOs via the EV roaming platform Hubject Brokering System.

Open InterCharge Protocol - functionalities & services

The OICP encompasses several distinct services within its framework.

, which handles all aspects of authorization, including remote start/stop functionality and the processing of Charging Data Records (CDRs). Next is the 

, designed for reserving charging stations. This feature can be optionally offered by Charge Point Operators (CPOs).

. These services involve the exchange of Electric Vehicle Supply Equipment (EVSE) information. EVSE data focuses on static information such as location, while EVSE status deals with dynamic data.

, despite its dynamic nature, primarily deals with flexible pricing, which we'll delve into further later. For now, it allows the exchange of pricing product details and identification of pricing products associated with specific EVSEs.

, which covers all events that can occur during a charging session, including start/stop actions, progress updates, and error notifications.

From the perspective of eMobility Service Providers, the services offered are quite similar to those of Charge Point Operators (CPOs), with one notable distinction. EMPs have the 

at their disposal. This service enables EMPs to transmit authentication data to the Hubject platform. This capability allows EMPs to function similarly to an offline EMP, a concept we've discussed previously.

Roaming via hub - The CPO and the eMSP system connect to based on web services Hubject B2B Service Platform. Both parties, the CPO and MSP, have an e-roaming contract through Hubject.

Ad hoc payment - ‘Intercharge direct’ is an ad hoc payment dedicated solution integrated in OICP and Hubject platform. This allows any contractless EV owner to charge up and pay at any charging station.

Authorization - Hubject links the IDs of eMSPs or CPOs and SSL certificate information. Then each does or does not authorize the charge session. Hubject’s database performs as back-up, but not actively support downloads from their database to the charging station.

Reservation - An EV owner can book a charge point e.g. via eMSP app. Hubject checks charge point compatibility with the EV.  If matches send the request to the CPO, which in return responds whether the booking was successful. A reservation can also be withdrawn.

Billing - Charge session data is recorded in Charge detail records (CDRs). Hubject passes on the CDR to the eMSP and stores the CDR in the system.

Charge point information - Uploaded charge point information can be distributed between CPOs and eMSPs via Hubject’s platform. The information areas are charge point ID, CPO, charge point name, charge point location (name, address, geocode, type), time zone, opening times, current availability, accessibility, tariffs, authorization modes, means of payment, charge mode, connector type, maximum power, hub connection, support contact number, reservation possible, real-time status information possible, predictive charge point usage, smart charging services, and the date of the last update. OICP maintains flexible pricing based on charge facility, charge point location, and time-of-use.

Real-time charge point information - This covers dynamic charge point availability status and tariff information.

Session information - Session ID, service specifics, charge point ID, authentication data, start and end time of charging, start and end time of connection, starting and stopping meter value, meter value in between, consumed energy, CPO ID, MSP ID.

Remote start/stop - From within the eMSP application, a charging session can be operated.

For those who look for a more in-depth knowledge, we have published a comprehensive

The European Union has made significant strides towards reducing its dependence on fossil fuels and promoting the use of alternative energy sources (especially in the more recent years). In order to facilitate this transition, the EU has implemented a series of regulations governing the development of alternative fuel infrastructure throughout member states. These regulations aim to create a more uniform and interconnected network of refueling stations for electric vehicles, hydrogen fuel cell vehicles, and compressed natural gas vehicles, among others. By providing incentives for the construction of new refueling infrastructure, the EU hopes to encourage more consumers to adopt clean energy vehicles and play a role in reducing greenhouse gas emissions. While there are still challenges to be addressed, such as the cost of building and maintaining alternative fuel infrastructure, the EU's regulatory framework is a promising step towards a more sustainable transportation sector.

Just briefly looking at the initiatives proposed within the last few years, one can already tell how much in this regard is happening across the EU.

In December 2019, the European Commission launched its landmark 

initiative with a mission to reduce greenhouse gas emissions in transport by 90%. Ambitiously aiming for climate neutrality through 2050, this far-reaching plan quickly gained momentum. In September 2020, the European Commission set a lofty goal - to reduce net emissions of greenhouse gases by at least 55% by 2030 and ultimately strive for climate neutrality across Europe. On 21 April 2021, this ambition took one step closer to reality as Council and Parliament reached provisional political agreement on legislation which is now known as the historic 'European Climate Law'

The newest big announcement that has lately made headlines was the Alternative Fuel Infrastructure Regulation (AFIR).

Alternative Fuel Infrastructure Regulation (AFIR)

As released by the official EU sources by the end of March 2023, 

Council and Parliament of UE announced the preliminary decision of rules for electric and hydrogen refueling infrastructure for EVs. 

AFIR’s main objectives circulate around the deployment of more recharging and refuelling stations for alternative fuels.

The agreement also foresees that Member States and industry should develop a European-wide coordination system for the exchange of information between publicly accessible recharging points and among stakeholders. This will help to optimise the use of current recharging infrastructure and allow drivers to locate them more easily. The existing public recharging points in locations where they are not yet needed, may be deployed in other places with higher demand. In addition, Member States can give incentives to the industry and private investors to develop and roll out recharging infrastructure.

In terms of the main regulatory pieces as kept from the Commission’s proposal, we read as follows:

“for recharging light electric vehicles, requirements for the total power capacity to be provided based on the size of the registered fleet and the trans-European network-transport (TEN-T) coverage requirements in 2025 and 2030

for recharging electric heavy-duty vehicles and hydrogen refuelling, requirements for TEN-T coverage by 2030, starting in 2025 for electric heavy-duty vehicles

for the supply of electricity to ships at the quayside in ports, requirements applicable from 2030”

as stated in the press release by European Council

During the talks and debates over the AFIR’s proposal, a few amends were however introduced, the European Council, again, lists them in the official press release. Below, the quote:

“given the specific dynamics of the electric heavy-duty vehicles and the fact that the market is less developed than for light vehicles, a gradual process of infrastructure deployment is set to start in 2025 aiming at covering all TEN-T roads by 2030

to maximise the efficiency of investments in hydrogen refuelling and to adapt to technological developments, the requirements focus on the deployment of gaseous hydrogen refuelling infrastructure with a particular attention to urban nodes and multimodal hubs

to ensure that electric recharging requirements are compatible with the wide range of circumstances on the ground and that investments are proportionate to needs, the total power of electric recharging pools has been adapted and the maximum distance between recharging pools for road sections with very low traffic can be increased

to make electric recharging and hydrogen refuelling infrastructure easy to use, different payment and price-display options are available, while avoiding disproportionate investment, particularly in existing infrastructure

regarding on-shore power supply in maritime ports, provisions are now fully consistent with the recently agreed FuelEU maritime proposal

the text specifies the obligations of each stakeholder involved, provides for progress tracking, ensures users are properly informed and supplies the industry with common standards and technical specifications

with a view to significant technological and market developments that will affect heavy-duty vehicles, the text of the provisional agreement includes a clause on a specific review in the short term, whereas the whole regulation will be also reviewed in the medium term”

In order for the preliminary agreement to come into effect, the exact details of the agreed text will still need to be formally approved by both co-legislators. Both sides are expected to sign off on the agreement shortly.

The Alternative Fuel Infrastructure Regulation will help to create a more connected and sustainable transportation system in the EU. By providing incentives for the development of alternative fuel infrastructure, AFIR promotes greater adoption of clean energy vehicles and reduces our dependence on fossil fuels. While there are still challenges ahead, such as ensuring access to necessary funding and establishing standards for public charging infrastructure, the AFIR is a significant step towards achieving a more sustainable transport. The Alternative Fuel Infrastructure Regulation will also open up new opportunities for businesses to develop and deploy innovative solutions in the field of alternative fuel infrastructure. Companies will be encouraged to roll out cutting edge technologies.

In the press release published by the Council on the 25th of July, it was confirmed that AFIR has been officially adopted

The new regulation will be published in the EU’s official journal after the summer. While it will enter into force the twentieth day after this publication, the new rules will apply from six months after the date of entry into force of the regulation.

In the Council’s press release we read about main deployment targets for 2025 and 2030. Those include charging network regulations for light and heavy vehicle transport, hydrogen refuelling as well as some energy-based regulations for airports and maritime ports.

Speaking about AFIR, we must take notice that it’s a part of a bigger initiative - Fit for 55.

The Fit for 55 package is an ambitious set of measures designed to ensure that the European Union meets its climate objectives and agreed between both lawmakers and industry. It provides a framework that allows for a transition towards greener policies in an equitable manner, safeguarding European competitiveness against third country operators while still leading on global action. This initiative establishes clear parameters for which businesses must operate if we are serious about achieving the long-term targets by midcentury.

The whole Fit for 55 package consists of many subsections, each regulating a different sphere of green activity.

The EU ETS is a major tool that helps the European Union reduce its emissions. Through this innovative market-based system, energy intensive industries and power generation sectors have seen significant improvements in carbon reduction—over 40% since 2005

The EU's Carbon Border Adjustment Mechanism seeks to protect the hard-won progress against climate change within its borders from being undercut by imports of high-carbon goods or offshoring production. By ensuring compliance with international trade regulations, CBAM bolsters Europe in incentivizing greater ambition worldwide on reducing emissions and tackling global warming.

Member states’ emissions reduction targets

The effort sharing regulation from 2018 sets yearly emission limits for member states regarding industries not regulated by other existing systems — such as emissions trading and land use management

Emissions and removals from land use, land use change and forestry

This plan increases their land use and forestry regulation, aiming for a minimum of 310 million tonnes of CO2 equivalent net removals by 2030 on an EU-wide basis. Each member state has been given individualized targets as well in this effort to reduce emissions from activities such as deforestation and agricultural production practices.

The proposal sets forward ambitious emissions standards for cars and vans across the EU, aiming to reduce these emissions by 100% by 2035.

Reducing methane emissions in the energy sector

This groundbreaking move is part of their Methane Strategy announced in 2020 and was followed closely by its Global Methane Pledge at COP26 last year where over 100 countries agreed to cut down methane levels by 30%. The proposal seeks to make tracking this progress easy as well as encourage greater reduction efforts

The FuelEU Maritime proposal is pressing for a reduction in the greenhouse gas intensity of energy used on ships by up to 75% over the next three decades. While some progress has been made, maritime transport still relies almost solely on fossil fuels and continues to emit notable quantities of toxic pollutants into our atmosphere. In June 2022, Council members agreed with its general approach before successfully reaching an agreement between both parliaments this March (2023)

With the ever-growing interest in our products and the EV industry reaching an all-time high, we recently shared some more information about our digital eMobility products on our social media channels. We’re now adding a short walk-through here, for those who look for a concise presentation.

EV charging management software. SaaS vs license - our approach

In today's market, there is no shortage of off-the-shelf products offering similar functionalities. While it is exciting to see technological advancements, operators must look beyond mere technical capabilities and consider the broader business perspective. This can be challenging since existing solutions typically adhere to rigid purchase patterns, predominantly offering Software as a Service (SaaS) options.

Based on our extensive experience working with various Charge Point Operators (CPOs), both in small and large businesses, we have observed that this situation can directly impact companies based on their scale and future objectives. To put it simply, as the charging network expands, the monthly fees tend to increase with SaaS. While this may not pose a problem for small operators with no plans for significant growth, it becomes challenging for those managing numerous sockets

Considering the rapid growth within the eMobility industry and the increasing number of CPOs entering the market, at Solidstudio, we strongly believe in the importance of freedom of choice when selecting a business model for software.

This invaluable experience has equipped our team with a deep understanding of the complexities involved in seamlessly transitioning software systems and we’re now happy to share some of the best practices when it comes to the software migration for an EV charging network.

While the points mentioned below serve as a general guideline for software migration in the EV charging industry, it's crucial to acknowledge that the extent of these tests may vary depending on the specific features and requirements of the system.

Migrating EV chargers to a new software - checklist

Migrating a charging network to a new software provider, which manages the chargers remotely, can be a complex process. It requires careful planning and execution to ensure a seamless transition.

Thoroughly assessing and evaluating the new software solution is essential before proceeding with the migration. It is important to verify that the new system can effectively handle the chargers, ideally exceeding the capabilities of the current software. During the assessment a lot of attention should focus on features that align with the specific requirements of a particular charging network and ensuring seamless compatibility with them. Such an “evaluating approach” not only mitigates the potential risks, but also guarantees an edge over competitors through picking out the most optimal solution.

Confirm Supported Charging Stations and Seamless Integration

Ensuring comprehensive support for all charging stations within the network is paramount when considering a new software solution. Thorough testing, including OCPP acceptance testing, is vital to confirm the seamless integration of the charging stations with the new software system. This rigorous step enables early detection of any potential compatibility issues, guaranteeing a seamless and successful transition process.

We add a downloadable guide on OCPP Acceptance testing including a checklist to go through. The PDF can be freely downloaded from the box on the left side of the page.

To successfully migrate the charging network, it is essential to first migrate the software structure. This step begins with a thorough understanding of the structure of both the old and new software, including aspects like charging pools and charging stations and their descriptions within the ecosystem. Familiarizing with the necessary features and ensuring that the new structure replicates them effectively is crucial to maintain the functionalities and capabilities of your charging network during the migration and after the process is finished.

Determine the Migration Method for Charging Stations

Once the software structure is well-managed, it is time to devise an appropriate method for migrating the charging stations themselves. Each charging station has a configuration called the OCPP URL socket, which determines the migration process. Depending on the requirements, the decision often circles around whether physical cable connections or remote methods are necessary for the migration. Planned and well-executed migration process allows avoiding any disruptions to charging services.

For networks with a large number of charging stations, a step-by-step migration approach is recommended. That is to begin with a smaller pool of charging stations in a controlled environment, ensuring the proper functioning of the new software solution. Then gradually expanding the migration process by adding more charging stations using a specific key until all stations are successfully connected. This phased approach allows for better management and minimizes the potential risks associated with migrating a large number of stations simultaneously.

Another critical aspect of the migration process is the transfer of OCPI connections. This step ensures that communication channels between the charging network and external partners or networks remain intact, facilitating uninterrupted data exchange and interoperability. It usually requires an in-depth analysis and quite often developing unique, fitting components.


For those who look to gain more knowledge on the OCPI connections and how they can be facilitated, we invite all to reach out to us.

EV charging software migration - process requirements + downloadable OCPP Acceptance Testing guide

Following up on the previous entry from our Software Migration short series, we’re now moving a step further into the topic. While the introductory article took on the preliminary aspect of the whole issue which is the decision making process, this time we assume the decision has been made and it’s time to choose the new software provider.

Similarly to the decision making process, there’s a handful of things to consider before choosing the right provider to which one’s bound to migrate. When it comes to software migration, selecting the right software provider is a crucial decision with far-reaching implications. Not only does the choice impact the overall success of the migration process, but it also has significant financial implications for the organization. The selection process requires careful evaluation of various factors, including the provider's expertise, cost-effectiveness, and ability to mitigate potential risks. Assessing these financial aspects and potential risks becomes paramount to ensure a smooth transition and maximize the return on investment (ROI) for the organization. By meticulously considering these factors, businesses can make an informed decision that aligns with their objectives and minimizes the potential for financial setbacks and operational disruptions.

With the decision-making process, we have grouped the arguments into two categories: product-based and business-strategic. In like manner we can now look at the intricate task of choosing a new provider. Two major points to consider are the financial aspects and potential risks for the business.


New software for the EV charging business.

When considering the implementation of a new software provider for electric vehicle charging, financial aspects and potential risks hold particular significance. The rapidly growing demand for EV charging infrastructure necessitates a reliable and efficient software solution that can accommodate the increasing number of users and vehicles. Choosing the right software provider entails evaluating their pricing structure, considering factors such as installation costs, ongoing maintenance fees, and scalability options. Additionally, potential risks such as system downtime, data security breaches, and compatibility issues with existing infrastructure must be thoroughly assessed. As EV charging software plays a critical role in customer satisfaction and revenue generation, businesses must weigh the financial implications and potential risks associated with the new software provider to ensure a seamless and cost-effective transition to support the future of electric mobility.


Choosing the new software provider - financial aspects

In the realm of software solutions, it is evident that the Software-as-a-Service (SaaS) model has gained immense popularity. The majority of existing software providers predominantly offer their solutions through SaaS, leaving organizations with limited alternatives in terms of business models. While SaaS offers benefits such as easy access and regular updates, it may not always align with the specific needs and preferences of every business. 

Unfortunately, the lack of alternative business models from software providers often restricts organizations from exploring options that may better suit their unique requirements

. The widely-adopted SaaS (Software-as-a-Service) model has its advantages, but it may not be suitable or satisfying for everyone. One of the key advantages of SaaS is that it relieves businesses from the burden of maintaining and managing the software, allowing them to focus on their core operations. Additionally, SaaS offers low capital expenditure (CAPEX) as businesses primarily incur operational expenditure (OPEX) costs. This makes it particularly appealing for startups with smaller charging networks, as it provides a cost-effective solution.

However, there are notable disadvantages to consider. As a business grows and expands its charging network, the costs associated with SaaS increase proportionally. The more chargers a business has, the higher the costs can rise, potentially reaching overburdening figures. This scalability issue raises concerns about the long-term financial sustainability of using SaaS. Moreover, SaaS sometimes does not provide the flexibility to customize the software to match specific needs, limiting the ability to gain a competitive advantage in the market.

As businesses contemplate growth and the expansion of their charging networks, it becomes crucial to consider alternatives to SaaS. Migrating to a software provider that offers a licensed model alongside SaaS could be a viable option.

 By transitioning to a licensed model, businesses can gain more control over the software and potentially mitigate the soaring costs associated with scaling up the charging network. Evaluating different business models and carefully weighing the financial implications will allow organizations to make informed decisions and ensure sustainable growth in the electric vehicle charging industry.

Another possibility for acquiring software is to have it custom made to meet the specific needs and preferences of a business. Custom software development involves creating a solution from scratch or modifying existing software to fit the unique requirements of an organization and may also be a pivotal argument in choosing the new provider.

Choosing the new software provider - customization & uniqueness

Custom-made software for EV charging offers distinct advantages that address the specific challenges and opportunities in the industry. 

By collaborating closely with software developers or development teams experienced in EV charging solutions, businesses can ensure that the software is built to perfectly match their workflows, charging infrastructure, and customer needs.

Moreover, custom-made software allows EV charging businesses to differentiate themselves from competitors and gain a competitive edge. By incorporating specialized features and functionalities, such as advanced charging management algorithms, dynamic pricing capabilities, or seamless integration with renewable energy sources, businesses can offer unique value propositions to their customers. This tailored approach empowers businesses to optimize their operations, deliver a superior charging experience, and align their software with their brand identity.

Custom software can also be easily scalable, allowing businesses to adapt and grow without facing the same scalability issues often associated with SaaS models.

However, opting for custom-made software in an EV charging business does come with potential disadvantages that should be taken into consideration. One significant drawback is the high upfront costs associated with custom development. Building software from scratch or customizing existing solutions can require a substantial investment in terms of time, resources, and skilled professionals. Additionally, the development process itself can be time-consuming, resulting in longer development times compared to off-the-shelf solutions. This extended timeline may delay the implementation of the software and hinder the business's ability to adapt quickly to market demands.

Choosing the new provider - mitigating risks & safeguarding the solution

When evaluating a new software provider for an EV charging business, it is essential to carefully consider the factor of risk. Transitioning to a new software solution inherently carries certain risks that need to be mitigated to ensure a smooth implementation and ongoing operations. One significant risk is the potential disruption to charging services during the transition phase. Any downtime or service interruptions can lead to dissatisfied customers, revenue loss, and damage to the business's reputation. Compatibility issues between the new software and existing charging infrastructure are also a risk, as they can result in operational inefficiencies and delays in providing charging services. 

It is crucial to assess the reliability and stability of the software provider, considering factors such as their track record, customer reviews, and the availability of comprehensive support services. Here’s where it might be a good idea to go with a provider that has proven history in creating solutions designed specifically for the industry. 

Additionally, data security and privacy risks should be thoroughly evaluated to safeguard sensitive customer information and comply with industry regulations. Similarly, to what we’ve touched upon in the previous entry of the series, the matter of data ownership comes to play here. The software that governs charging stations stands as a vital element in a CPO's infrastructure.

 Unfortunately, this software is commonly owned and managed by a third party, leaving CPOs vulnerable to risks that are beyond their control. 

The substantial investment made in establishing a network of chargers further magnifies these risks, underscoring the importance for CPOs to evaluate potential hazards and implement measures to mitigate them. 

One potential remedy is to transition to proprietary software or acquire a license, reducing reliance on third-party providers and granting CPOs greater autonomy over their systems.

 By thoroughly assessing and managing these risks, EV charging businesses can choose a software provider that minimizes potential disruptions, ensures operational continuity, and supports their growth and success in the rapidly evolving EV charging market.

Software migration - choosing the new provider for eMobility software

It’s probably every year that we get to hear that it’s the most technology-progressing year to date. And it’s most probably always true, given the galloping pace of the tech industry worldwide. Staying up-to-date with the latest technological advancements has become more important than ever before. The emergence of new hardware, software, and AI solutions has created new opportunities for businesses to streamline their operations, enhance customer experiences, and gain a competitive edge. However, the momentum of innovation in the tech industry has become so unparalleled, that businesses which fail to adapt and evolve with the times are bound to fall behind.

With that, in times so inundated with newly-introduced breakthroughs and changes of direction, one must put a great effort to stay afloat. This includes making often gnarly decisions on what’s the best for the company here and now. Entrepreneurs are left with the need to carefully evaluate which technologies are relevant to their specific needs, plan for their adoption, and ensure that their teams are trained to use them effectively. Those who do not take proactive steps to embrace the latest technological advancements risk being left behind by their competitors.

Software migration in EV charging business - what drives the need?

The growth of electric vehicles has fueled the development of software solutions aimed at streamlining the EV charging business. Software developers are creating innovative applications that enable EV drivers to find and reserve charging stations, pay for their charging sessions, and monitor their charging status remotely. These software solutions are also helping charging station operators to manage their charging infrastructure more efficiently by providing real-time data on charging usage, optimizing energy distribution, and identifying maintenance needs. Additionally, software is being developed to integrate EV charging with smart grids, allowing for better load management and the use of renewable energy sources.

With ongoing advancements in software development, the EV charging business is becoming more user-friendly, reliable, and environmentally sustainable. However, there are some obstacles on the path to achieving the optimum pitch. Here’s where continuous upgrades, including software migration, strike as a must.

Software migration involves transferring an existing software system from one environment to another, such as switching operating systems, hardware platforms, or programming languages. This is typically necessary when organizations need to update or replace their software to keep up with their evolving needs and the latest technology. Software migration can be a complex and challenging process, and it requires careful planning, testing, and execution to ensure a successful outcome.

Within the eMobility ecosystem one can observe a vivid differentiation between Charge Point Operators and the software providers, leaving some of the crucial data in the latter hands. Meanwhile it's the CPOs that happen to know the industry best and experience first-handedly how the needs are changing.

Prime example of such change is the volume of chargers that comes to the equation and the legacy tech stack. 

(Legacy tech stack refers to a set of outdated technologies, tools, and programming languages that are still in use in various software applications and systems. These technologies were popular in the past but have become obsolete or are no longer widely supported by their respective vendors

While legacy tech stack may still work, it can create various issues for businesses, including security vulnerabilities, higher maintenance costs, and a lack of scalability

). In the eMobility business, legacy tech stack (that’s still in use by some) was designed to serve a couple hundred charging stations at best. Nowadays, some operators have thousands of chargers within one network and require a whole new level of adjustability from the software solutions that are used to manage the network.

As software continues to evolve, outdated versions become less reliable and less secure. Newer software solutions offer upgraded features and enhanced security, making them a more enticing option for users. Businesses must adapt to stay competitive in the ever-changing digital landscape.

To focus strictly on how that’s driven within the eMobility industry, we distinguish two prime areas within which one needs to decide on the pros and cons of software upgrades. The first involves all the rudimentary arguments regarding the digital products themselves. The second requires some more thoughts and is touching upon the strategic aspects of running a business.

Product-based arguments in favour of software migration

As briefly mentioned before, the first area that needs to be considered involves all the aspects relating to a certain digital product as such. This mostly includes the rough technicalities. As for the EV charging software, there’s a few main points to deliberate over:

In addition to the above, there are several other reasons why businesses in the EV charging industry may need to consider software migration. For example, outdated software may be incompatible with new hardware, making it difficult to integrate with the latest charging infrastructure. Additionally, new regulations and industry standards may require businesses to update their software to newer versions.

But for now let’s focus on the 4 main points.

As the EV charging industry continues to evolve, businesses may find that their current software lacks essential features that are now in demand. For instance, customers may expect to have access to real-time information on charging station availability and pricing, as well as the ability to reserve and pay for charging sessions through a mobile app. If businesses fail to provide these features, they risk losing customers to competitors with more advanced software solutions.

Outdated software in the EV charging industry may be unstable and prone to errors, leading to system crashes and downtime. The main issue that can cause major inaccuracies in the case of EV charging software is the lack of stable options for scaling up. As businesses grow and add more charging stations to their infrastructure, operators must ensure that the software can handle a higher number of sockets or clients without experiencing system failures. For instance, if a software solution can only handle a certain number of charging stations or users, it can become overwhelmed and crash when businesses try to add more chargers to their network. Upgrading to new software with more advanced features and scalable options can help businesses avoid system failures, reduce downtime, and ensure the smooth operation of their charging infrastructure as they grow.

When businesses in the EV charging industry experience technical issues with their outdated software, they may have to deal with lengthy waiting times for ticket resolution. For example, if a charging station becomes disconnected from the software system, it may be difficult for businesses to diagnose and fix the problem without technical support from the software vendor. In some cases, businesses may have to wait for days or even weeks for a ticket resolution, leading to increased downtime and lost revenue. By upgrading to new software, businesses can receive faster and more reliable technical support, reducing waiting times and minimizing disruptions to their charging infrastructure.

Outdated EV charging software may also fail to meet legal requirements set by regulatory bodies, leading to compliance issues and potentially even fines or legal action. Regulations around EV charging infrastructure can vary by region and may include requirements related to data privacy, accessibility, and environmental impact. If businesses are using outdated software that does not meet these requirements, they risk running afoul of regulatory bodies and facing legal consequences. By upgrading to newer software solutions that are compliant with relevant regulations, businesses can ensure they are operating within legal guidelines and avoid any potential legal or financial repercussions.
