When you have a site – building, public site. A site has a certain limit of energy capacity (current), current that you can provide in a certain moment. The current can be for the whole building or the limit can be for EV only. In order not to exceed this capacity, we need to have a system to manage that maximum current capacity and is able to distribute the energy between the other energy consumers and or/ other EVs that are charging simultaneously.
In EV Meter Core (our management platform), we can define the maximum current capacity in a specific location and the system distributes the energy between the charging stations, according to specific pre-defined logics. There are different potential scenarios: either there is enough current for all the cars, and each one can receive a certain amount of energy, or there is not enough energy for all charges at the same time, then some cars will receive and some will receive later on.
