    At the most recent two public L2 charging opportunities my 2018 Prime stopped charging prematurely. The incidents were very similar.
    • Plugged into a public L2 charger
    • The battery was 0% before starting (after long drive).
    • Charging stopped by itself at 2.3kWh (1st instance) and 2.5 kWh (2nd), approx 50 minutes.
    The car charges just fine from my L1 charger at home.

    At the 2nd incident, I noticed the 3 blue lights were very slowly blinking together, maybe every 15 seconds or so they would blink on for a short moment. Unplugging and restarting the Chargepoint restarted charging, which then proceeded for 51 minutes 2.7 kWh without incident until I unplugged.

    I don't have any charge schedule set. It has been on charge-now ever since I bought the car, I just checked this is still true.

    This happened at 2 different chargers: an EV Passport and a Chargepoint. I figured the first instance was a fluke. But now not so much.

    This summer I had a similar experience. However, it did not completely stop charging, just severely reduced charging speed down to L1 charging rates. It usually happened while using the schedule, but once happened when I had it set to charge now. I am not sure if there was something wrong or if it was a feature to prevent the battery from overheating. Here are some screen shots of the charging sessions where this happened. Luckily it hasn't happened since October.
