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.

Charge Point Operator platforms, eMobility Service Providers apps for end-users, Open Standards and facilitations for their integrations, eRoaming, smart charging, connected cars and the list that goes on - software solutions have 

solidified their place in the eMobility ecosystem

 and they’re now making up for a huge part of its proper functioning.

While an ordinary EV driver may not be aware of the amount of software running in the background and facilitating the whole electric car experience, it’s a case well-known to any eMobility operator, of which a great majority came across a rather difficult task of choosing the right digital products at some point.

There is a fair share of such on the market and quite a few available as ready-made products already. Many of them remain very similar in terms of the integrated functionalities and features. This includes open standards facilitations, user management, remote start/stop features, etc. While it’s fantastic to see the technology growth behind the industry, an operator choosing the right software must take into account a broader range of needs than just a great software. Here’s where the situation may get tricky for some of them. Existing solutions are usually offered via strict purchase patterns, which often start and end at SaaS (aka Software as a Service).

Much like in any other situation, SaaS has strong benefits for some of those operating in the eMobility ecosystem, yet it’s not a one-fits-all solution. In order to see why, we’ll elaborate a bit on both.

Software as a Service (SaaS) is a way of delivering software applications to customers over the Internet. Instead of buying and installing software on their computers, customers access the application through a web browser or mobile app. They can then share data and collaborate with other users in real-time. SaaS eliminates the need for expensive hardware and software licenses, meaning businesses save money and time on IT (at least when it comes to the upfront costs). With SaaS, users can access their applications anywhere and anytime, giving them flexibility and control over their data. Additionally, maintenance and upgrades are handled by the provider so users don’t have to worry about keeping their systems up-to-date.

There is however a major drawback of SaaS. Namely, the costs often increase as the business expands, which can make scaling a costly venture.

With that, for small business owners, SaaS can be an invaluable tool for streamlining business processes and increasing productivity – all without breaking the bank. By eliminating costly investments in hardware and software, businesses save money while still getting access to all the features they need.

Unlike SaaS, a software license is a traditional way of purchasing and using software. With this approach, businesses buy a specific number of licenses for the software they need and install it on their systems.The advantages to this approach are many. First and foremost, businesses don’t have to pay ongoing fees for the application. They’re also able to customize their software as needed, and they can use the licenses for any number of users.The main disadvantage of a license is that (sometimes) businesses have to take care of maintenance and upgrades themselves. Additionally, since businesses must pay upfront for the licenses, it can be more expensive to start with than using SaaS.

The biggest difference between SaaS and software license is the cost structure and ownership. With SaaS, businesses pay a monthly or annual fee to access the application. With a software license, businesses purchase a one-time license for the number of users they need and own it outright.

Another difference lies in who is responsible for maintenance and upgrades. With SaaS, the provider is responsible for keeping the software up-to-date. With a license, companies must take care of maintenance and upgrades themselves (it must be noted here, that there are however licensed solutions offering the updates).

We have covered a lot more on the similar topic in our article 

 - check it out to learn more in greater detail.

Having worked with all kinds of CPOs out there, whether small or big, we’ve noticed that said differences can directly affect the businesses depending on their scale or future goals. We have also noted that EV charging software is usually available only via SaaS, which in this particular case results in higher prices as the charging stations are added. In simple terms, the more the charging network grows, the more the monthly fee is bound to increase. While it may not be an obstacle for small operators with no views of siginifiacnt growth, the case gets slightly difficult for those who get to operate numerous sockets.

Given the rapid pace of growth within the eMobility industry and the fact that more and more CPOs are entering the market, at Solidstudio, we strongly believe that the freedom of choice is required when picking up the business model of the software, so that all can have a cost-effective and most optimal solution.

Knowing this and knowing the nuances behind the software purchase models, we decided to make our products available via either SaaS or license and even more… Namely, we give the flexibility to change the the model once either becomes more efficient. That way one can start with SaaS and then move to license once the amount of charging stations under control becomes more expensive to be held under SaaS than it would be with license. With that approach we made sure that our digital products are serving equally well for each and every client.

Since the two concepts of purchasing software may get a bit complicated and unclear at first, we thought it would be best if anyone could compare the specific prices and see the numbers for themselves.

With that in mind, we made available an online tool allowing for exactly that.

 compares any costs you choose with what it looks like with us - whether its licence or SaaS. You can enter whichever amount of charging stations you like (the more stations, the more you save). We also elaborate on some more details in terms of the benefits and drawbacks of each business model.

As the post-conference feeling is still in the air after the International Electric Vehicle Symposium & Exhibition in Oslo, there are also many interesting observations and remarks.

The first that comes to mind is definitely how far has eMobility come in the last few years. And it’s been a long ride filled with innovation and groundbreaking changes implemented one by one. The progress in hardware is astounding to the point where some of the devices could merit a sci-fi label. From new-world chargers powering an electric truck at 1.5 MWh, to electric helicopters looking a bit like flying cars, it’s free to say that eMobility is here to stay and such events are the best proof.

What was also a bit surprising is that amongst hundreds of hardware and business exhibitors, there were very few representatives of the software side behind all of it. And yet, it plays a huge role in making it all possible.

Sure thing, possibly the most important aspect behind the mass EV adoption are the cars and the chargers. It’s what attracts the customer first and makes one join the green side of transportation. However, one must remember that it is the digital products that run the EV show in the background.

Charging networks, especially smart ones (aka the ones that bring the most opportunities to the field), can be deemed “smart” solely because of the backend platforms enabling the data exchange between a car, a charger and energy provider. 

run the entire charging station pools remotely, with the use of such programs in a way that ensures a seamless continuity of operation, even when there’s a high demand or minor issues.

 is still one of the biggest eMobility obstacles, reassurance in a smooth charging networks operation is one of the crucial steps to take in order to dispel doubts about it.

 - the figures that take care of the end-users, EV drivers. Most charging stations can be utilized from start to finish via the use of a dedicated app. Electric vehicle users now can not only start charging and get billed from the comfort of their phones, but also perform actions such as a charger reservation or price optimization depending on a tariff. It’s a facility necessary to promote EVs, giving their owners a peace of mind on longer routes as well as daily commute.

Software also runs the charging from a wider perspective. As there are numerous Charge Point Operators and eMobility Service Providers across the regions, a way has been found to unify their services so that they can serve as many EV drivers as possible. eRoaming comes into play allowing for multi-dimensional connection between operators and EV drivers.

In short, eRoaming can be established via the use of hubs and protocols. A hub here can be an open platform which, after subscribing, can be used by many operators, who operate on common terms. This all happens in such a way that a certain charging pool introduced to a common hub can then be easily used by clients (EV drivers) of different providers. Such a solution allows electric vehicle users to charge their car across cities/countries with limited hussle. The solution is entirely facilitated through a complex cloud-like backend system.

Software plays a big role also in keeping the energy distribution as sustainable as it gets. Through the backend smart charging facilities, charging stations can monitor and adjust electricity used so that the grid remains safe from overrunning its capacities. What’s more it’s also the digital products that, to a great extent, allow for V2G technology. Namely, one of the smart charging features facilitates the process of pushing the extra energy from an EV’s battery back to the grid, ensuring no energy is wasted and rooting the industry deeper in its eco-friendly aspects.

Finally, apart from the charging-maintenance aspects, software reaches further, all the way to its impact on transportation as a whole. Something called connected car data is being used across all types of vehicles for a while now. Connected cars are capable of gathering all sorts of information. From principle information, such as the speed or location, through engine status and malfunctions all the way to details such as whether the door was locked. Information is then used for many ways, from enabling shared transportation and services like Uber, to data used by insurance companies.

It’s free to say that software in eMobility touches all its aspects and makes improvements in all areas.

: As software becomes increasingly important in the development of new electric vehicles, companies that have strong software development teams will be able to bring new products to market faster and more efficiently.

: software can be used to improve the performance of existing electric vehicles. For example, software updates can be used to increase the range of an electric vehicle or to improve its charging time.

: software can be used to develop new chargers that are more efficient and easier to use. This will help to accelerate the adoption of electric vehicles.

: software can be used to improve the efficiency of existing charging stations. For example, software updates can be used to increase the speed of charging or to reduce the amount of energy wasted during charging.

: software can be used to develop new apps and services that make it easier for people to use electric vehicles. For example, software can be used to develop an app that helps people find the nearest charging station.

Given all the aspects of the eMobility world enabled by software solutions, it’s pretty evident that electric vehicles are software-dependent, and this is likely to continue in the future. As such, it is important for companies operating in the eMobility space to have a strong software development team, whether in-house or outsourced to ensure the highest level of smoothly-running services.
