I plan to purchase a new electric vehicle in the coming months (a Tesla Model 3). My parking garage in my apartment building offers electric vehicle charging (unlimited charging for an extra $50 per month).
However, as I'd probably want to get them to install another wall adaptor near my spot (rather than move my spot to one that already has a charger) I thought I might suggest options that would be more fair. $50 per month seems steep with light use, while with a Tesla and heavy use, I could probably draw enough power to make their eyes water when the power bill arrives, so much that they would likely jack up the rates. So my thinking is to negotiate an arrangement where I simply pay for my share of the electricity.
My ideal solution would be to find a system that could measure usage for particular vehicles charged at that charging station. While I am out at work, they might charge another EV vehicle so if I just got them to put a meter on the wall adapter to pay my share of the electricity, I might end up paying for someone else's charging.
Are there (consumer grade) charging systems (wall adapters) that will track usage? The perfect one would be one that doesn't need a RFID card or code to activate, but just picks up the VIN number or whatever from the vehicle when it is plugged in. The parking garage has WiFi so in theory there could be a charger that does this and uploads the statistics to the cloud so one could get a statement at the end of the month, when it is time to pay for the parking spot.
