As most of us know, EVgo charges by the minue rather than per kWh. What I've observed (after looking through previous charging events), is that EVgo seems to ignore the seconds spent charging. For example, during a recent charging session, I charged for 28 minutes, 54 seconds and was billed $2.80 (10 cent/minute Bolt promo plan). EVgo didn't round up and bill me for the additional 54 seconds. I looked through my charging history and saw I consistently billed only for full minutes spent charging. So if possible, stop your charging session just before it rolls over to the next minute to save a few cents. And not right after it rolls over to the next minute. This ain't gonna make you rich, but hey, a penny saved is a penny earned, right?

You are absolutely right. I looked over three months of statements and compared to the EVgo e-mail reminders sent after a charge session was completed to see that per minute charges are rounded down to the last complete minute.



The final cost varied by state (I charge in NY, CT, MA, and ME) because some jurisdictions add tax on the per-minute fee.


As to the value of the round-down, the best I can get on a 30-45 minute charge is 0.63 kWH delivered/minute of charging. This comes from EVgo 125A stations and reflects charging rate step-down as I reach 50% charge.



Still, up to 0.63 kWH 'free' is about 2.5 miles of no-cost driving....

If they are charging by the minute, be sure to avoid 'topping off' your battery. The rate of energy delivery (power) drops sharply once the Bolt gets to about 90% to 95% of capacity.

And we wonder why companies don't want to get involved with charging cars.

"Nothing in life is free, except EV charging" . I am starting to get over that mind set. Could be because there are still free ChaDeMo stations around here for my LEAF, but I haven't found a free CCS for the Bolt yet. When the EVgo (and competitor) stations start getting lot's of use, we'll start seeing stations popping up like dandelions in spring. You have to think about that when your paying EVgo. I have yet to see another EV at the EVgo station I've been using, making me wonder more about how they can afford to install it if it gets so little use.
