If Tesla likes DC, those GPIOs have a whole 2mA! Nice project and installation though, was just a bit confused by the title. edit: I think a common EV battery would need around 4800h neglecting efficiency loss from voltage conversion. So let's say an EV would need around 2/3 year to be charged by a Raspberry Pi GPIO. Workable if you have a reserve of around 200 cars.
