I have noticed that issue popping up more where the chargers are only outputting 33 kW. They've definitely been derated to only 100 A, and I'm not sure why. It's possible that there's a malfunction in the coolant system, so the charger automatically reduces its charging speed to prevent damage. This mostly occurs on new installations, so my assumption is that it's a problem with the contractor who improperly installed the equipment.Does EA have a new issue? My wife and I drove from the DFW area to Austin on Memorial Day for a day trip to visit our daughter. We stopped at the Bellmead/Waco location going both directions and observed reduced charge rates. The peak rate was about 33kW when I expected ~54. In Austin we charged at a ChargePoint site and observed the expected rate. I left feedback for EA via the email receipt they send, but haven’t received a response yet The two sessions were on different chargers - one was a 350 and the other was a 150. Looking at plugshare chech-in comments for some other EA locations in Texas recently, I saw a similar comment from a Bolt user at the Sweetwater location in late May. I’ve used this and one other EA location multiple times and never observed this phenomenon before. I’m primarily concerned because my son and I are planning a trip to Guadalupe national park in a few weeks and we’ll rely on the EA locations on I-20 exclusively. 33 vs 54kW will cost a lot of time!
For what it's worth, Electrify America is the only public charging provider I've used frequently that still has a 100% success rate at a site level. They've had a few close calls (i.e., only one charger functioning at the site), but I've always been able to activate a charge. I can't say the same for ChargePoint and EVgo. Recargo only has one site, and I've only used EV Connect and GreenLots a handful of times.
At this point, if I had to rank reliability on a per-charger basis, it would be:
#1: EVgo (by a wide margin)
#4: Electrify America
*EV Connect and GreenLots TBD.
