I drove from Central New Hampshire to Poughkeepsie last weekend (260 miles), charging at the Lee service plaza fast charger on the Mass turnpike. I had planned to slow charge over the weekend, but my brother's house has an ancient, ungrounded electrical system. We found one three-prong outlet in his garage, but the stock charger lit the red "No way, Jose" LED when we plugged in.
My impression of the fast-charge process--certainly EVgo's implementation--is that it could stand some refinement:
1) The DC Fast chargers at the Lee Service Plaza on the turnpike (both directions) are EVgo branded, but they do not show up in the EVgo app (PlugShare ftw). The support person I contacted seemed very confused by my pointing this out.
2) The fast chargers were 100 amp. It took over an hour to bring the car from 10% to 80% charge. The Bolt told me how long before it would get to 80%, but not the charger. Observed rate seemed to be roughly 1%/minute up to 70%, which is about what I've seen on graphs posted here.
3) The charger shut off after an hour. There was nothing that indicated it would do this.
4) I fielded questions about the car and about the charging process from a number of people. The most common question was about cost of charging, with the assumption that it was free. Fast chargers should show accumulated cost of charging on the screen, just like gas pumps do, and that info should be available before a driver plugs in. That would help bust the prejudice I've seen that EV drivers are benefiting at others' expense.
5) When I returned, my wife asked how I knew the machine had delivered the energy it said it did. It was confirmed by the Bolt, of course, but it does make me think that fast chargers and public L2 chargers should be subject to some sort of state weights and measures inspection.
Overall the trip went smoothly, but it will be tough not to take the minivan on future trips. An hour's charge for three of driving is just too long for my tastes, and EVgo at least doesn't fully have their act together.
