Where are you located? In some (US) states, it is illegal to resell electricity, so companies with EV charging networks in those states (including, for example Tesla) charge by time, rather than by the KWh. In this way, they are basically able to claim that they are charging for parking, while the electricity comes along for free. In other states without those laws, many of the networks charge by the KWh.
