I charge at home on a dedicated 20amp circuit using an EVSE that allows me to charge at the 1.6kwh max for the 20amp circuit. I normally charge every day or every other day from a SOC of no less than 70% to the limit I've set at 80% (as you can see, I don't drive all that much). This has worked flawlessly for almost 2 years.

Two of the last three times I've charged my car, charging has failed to stop at the limit. The first time, I was charging overnight, and when I went to drive in the morning, charging was still active and the SOC was 85%. The next time, charging automatically stopped at 80% as normal. Last night, I monitored the charging on the app. Charging reached 80%, but failed to turn off, and the app stated that there was still 11 hours +/- to go. I manually sopped the charging.

Has anyone experienced this problem and know how to avoid it? Any ideas as to what is happening?

Thanks.
