This was a Rivian-sponsored charger at a TN state park. I previously charged at this location in January (I do not remember what power delivery rate the EVSE reported then). Yesterday, I started the charge and about 15 minutes in, the charge stopped. I knew the car was not full, so I checked the EVSE display and initiated charging again via the fob.
Just like the initial charge 15 minutes earlier, the EVSE display reported that it was sending 7.2kW to the car. After the charge stopped immediately this time, I disconnected the cable and reconnected it. The Clarity's charge port light was fast-blinking (while disconnected and connected) and charge initiation via the fob would not work. I got in and powered up the car and the display reported "charge system malfunction, vehicle power degraded" or something similar. I moved the car to a different parking spot and did an overnight backpack.
Today, back at the car, when powered up, the check engine light was on but there were no charge system warnings. Not wanting to press my luck, I didn't try to charge there again.
I power cycled the car and the CEL remained. We headed home but stopped for lunch after about 40 miles in HV mode. Likely after starting up for the final leg after lunch, the CEL was gone. I failed to notice when we left the lunch spot but noticed about 10 minutes later.
Other bits of data:
1) 2018 Car has 68k with slightly more than half estimated in EV.
2) I primarily charge on 120V with maybe 50 partial charges on L2 since Dec 2017.
3) I had driven mainly in HV mode getting to this destination but switched to EV for last ~4 miles. Ambient temp 70F.
4) Battery was at approx 60% SOC.
5) I do not have an OBD2 scanner to check the error log (Question: will the recommended model for reading battery capacity also read all DTC error codes for the Clarity?)
6) My phone (and possibly the TCU) had no cell coverage at this location, so I could not confirm how much charge the car took. 15 minutes would have been about 10% but I did not note the specific number of charge bars on the vehicle display. During that time, it did sound like it was charging.
Since there isn't an 8% efficiency loss in a new charge cable (I believe I was the first person to use this EVSE in January), was the EVSE really sending 7.2kW to the car even though the car should have told it to only send 6.6 kW?
