Site owners typically manage energy contracts, while parking spaces are allocated to or shared between individuals who rent apartments - and who will naturally have visitors and guests, who in turn will increasingly have their own EV charging needs.
Additionally, you might also have other players involved: facilities managers, or perhaps a dedicated charge point installer/operator who looks after the EV charging infrastructure.
Not only that, you need to bear in mind that the parking locations can have limited bandwidth — both in terms of connectivity and power capacity.
In this complex scenario, you want control – to monitor and balance energy usage, to bill the right people for it, and to deliver the most seamless experience for all users - in order to capitalize on the investment made.
