Right now, station owners are limited to charging per minute, and because vehicles draw different amounts of power over the same period of time, we're essentially having a cross-subsidization situation. Two vehicles might pull in. The station might have the same level of power, but over a 30-minute period of time, one vehicle that has a bigger battery might be drawing more. If we're charging them the same price per minute, we're essentially cross-subsidizing and, as the station owner, you don't have a really good idea of what your costs are to cover because you just have a flat fee per minute.
