I usually use the superchargers about twice a month and just noticed today, May 20th, that I'm now being charged per kwh, whereas my previous charge on May 4th was per minute. I'm guessing this change is statewide as all the stations within a 20 mile radius are now charging per kwh. The part that sucks is the price has just about doubled for almost the same amount of kwh used/added. Does anyone know when this switch to charging per kwh happened exactly in NJ? I can't find any official statement on the switch.
