Starting from 2020, an exponential growth in the use of electric cars has been reported, exceeding 55 million in late 2024. This increase led to a rise in the demand for public charging stations, which in that period were less than 6 million and could not keep up with the increase in vehicles. To support the increase in electric vehicles (EVs), charging points should be scalable, compatible, and flexible for the upcoming technologies. Many of the charging stations on the market use closed-source software. These solutions have many positive sides, such as vendor support and maintenance, reliability, integrated ecosystem, and optimization based on the hardware; on the other hand, they expose stakeholders and users to significant risks, including vendor lock-in, high implementation costs, limited interoperability, and vulnerability to service discontinuation, as demonstrated in recent cases.
