Did the amount of time of charging vs. filling up a tank come into play?
I had previously heard that Fast DC chargers bill by the minute and not the amount of juice. However, when I charged up on the road, it was my understanding that I was billed by the kWh, not by time. That was with Electrify America, 8 or 9 times, in New Jersey, New York, Maryland, Virginia, & North Carolina. I guess that makes me the expert
. It might be different with other brands of Fast DC, or other states.
I recently got an email from Electrify America announcing new billing rates. Instead of the fixed rates of 48¢/kWh (with no monthly fee), or 36¢/kWh (with $4/month fee), their new rates will vary by state and local electricity rates. And, they will begin to bill people who leave their car occupying a charging spot more than 10 minutes after their charge up is done.
