A Bolt EV still needs about 90 minutes to do a full charge, and an hour to do a decent charge.
I used them today on the new structure.
45 minutes gave me 20.4 kWh (one-third of a “tank”)
And cost me $9.20.
Yup. $9.20. Not a big deal, but 45 minutes x $0.20 per minute comes to $9 even.
Seems I was “connected to their network” for 45 minutes and 18 seconds. Even tho thier system started and stopped my charge system automatically, they learned from the cell phone companies how to charge for partial minutes. Also, since it was my first time and I didn’t pay that close attention, I don’t know if I was being charged during the 1 to 2 minutes of “handshake” time while thier network was communicating with my account, and the car was making a handshake with the charger.
Still better. But not as cheap or as good at ChargePoint. ChargePoint is most commonly $0.25 per kWh with no time limit, though I’ve seen higher, and they usually only charge by the kWh, although busy stations sometimes tack a per minute charge also, to encourage you to “move along” as soon as possible.
EVgo cost me $0.45 cents per kWh.
Pretty pricey, especially for what is essentially "half speed" fast charging
Doesn't the Bolt charging rate start to taper off after 50%? Also, was the station a 50 kWh ABB or the 40 kWh Drive the Arc? My Spark EV starts tapering off at 80%. However, I usually charge to 90% or 95% and, from my current statement, I am averaging 1.4 min per kWh [50 kWh ABB] for the entire charging session. At my current special offer rate of $0.15 per minute, my cost is $0.21 per kWh. At my regular EVgo membership rate of $0.21 per minute, my cost will be $0.30 per kWh. Note: For comparison, my current PG&E cost per kWh is $0.21169 for tier 1, $0.27993 for tier 2 and $0.43343 for tier 3 [rate plan E-1].
You averaged 2.21 min per kWh which suggests to me you were into the "tapered" charging area. You might want to check you minute / kWh rate before and after 50% to see how they differ as you approach 80 to 90% full charge.
I can't foresee any logical reason it would begin tapering it's charge at 50%, right when the chemistry is at it's most viable.
