I just completed a 1500 mile trip in my 2019. On the return leg the a fast charger shutoff at 58%, at my next charging stop, I stayed in the car and noticed that at 58% it sounded like the AC compressor turned on. This was follow by a notification that fast chaging was terminated. The outside temperature was 70 deg - earlier on the trip I charged at 95+ deg with no problems. Has anyone heard of this issue?
Some chargers limit sessions at 30 minutes or the charger itself over heats. If it's consistently happening and an issue with the vehicle you should get trouble light and a DTC.
I used an EVGO DCFC yesterday, in Roseville CA, and my session was 35 minutes. It stopped because I reached the first taper, and I manually stopped it.
Would be nice if the free stations do that and prevent you from getting another 30 min until another car had a chance to charge (this would require that the charger can read the VIN) and prevent people from hogging the DCFC trying to get to 100% charge.
I read here that the last 20% on DFCF is much slower than the preceding fill up. Do people really sit there and go to 100%? I'm still throwing up in my mouth at the thought of charging outside of home unless it is 100% absolutely necessary and completely unavoidable.
Using an Electrify America DCFC once, charging randomly stopped after about 15mins. I don't recall the state of charge (would be weird if it had been 58%!), and I didn't have time to mess with it, so I left.
In general I have about 50% luck with DCFC of all kinds, which really does not inspire confidence for long trips, especially in winter...
This was an issue specifically with ABB Terra HP chargers that I encountered (both on Electrify America and on EVgo). I believe it has since been patched. I actually ran into this issue on EVgo when I was driving out to Las Vegas and back (it's visible at 5:39 in the video).
Again, though, this hasn't been an issue for awhile, and I think it was corrected at the same time ABB issued a patch to address issues that Chevy Spark EV owners were experiencing.
Does anyone know (from spec sheets, or personal experience) if extreme heat would prevent a DCFC session from starting up? One of my road trip ChargePoint fails was on a really hot day (upper 90s), right after getting off the interstate. I wonder if the car/charger decided it was just too hot to start a session? (Or should it have still charged, just maybe slower...)
I've seen medium speed chargers start then quickly drop down to lower charge rate and then shut down, but I think that was because it had a broken cooling fan.
