I've been on the other side, that is implementing the charging algorithm in the vehicle, it was very difficult to have a consistent behaviour over the many EV charger.<p>As I understand, this solution is for the backend, connecting the EV charging station with the internet, but it is not used to connect to the EV.<p>Many of our clients thought they just needed to buy/install such a solution to have a fleet of smart charging vehicles, because that is a crowded space and that is what the vendor sold. The issue was the interface EV <=> EVSE as the protocol used for charging was not incorporating smart charging feature (newer protocol was being written at that time). We had to hack the protocol to implement some features.
