Charging you for electricity, why that's terrible. I don't know why the oil companies don't give me free gasoline either. Free charging has been used as a gimmick trying to promote EV but as it becomes more popular, I don't think it is sustainable to expect other users to subsidize you. We all use and pay for our electricity.
Most electric vehicles can be charged in two distinct manners: 1) An on-board charger that can be connected to a variety of AC sources. That generally includes at least a household 15A, 115 V circuit, a 30A 230 V (dryer or range type socket) and possibly industrial 3 phase plugs. This allows "charging anywhere" but at a rate limited by the ac service available. 2) A DC connection to an (expensive) external fast charger.
