With the cold weather over the last couple of days I’ve started having an issue where my M3 fails to start charging on a timed charge. I’m using a Zappi v2.
I’m plugging the car in the afternoon/evening with a timer on the Zappi so the car won’t start charging until 2330. Two nights ago the car didn’t charge at all overnight. When I checked it in the morning the Zappi stated the charge was delayed and when I manually tried starting the charge through the Tesla app it simply failed. When I went out to check the car the charge port light was red. I unplugged and plugged back in and it started charging.
A similar thing happened last night, however this time I stayed up until 2330 to ensure the charge started (we were at 11% ). The Zappi was on Fast and showing charge delayed. The car simply wouldn’t start a charge and showed the cable as grey in the app (though it did show plugged in). I went out to the car and again the port light was red. It took some effort to remove the plug as it seemed to be frozen in place, but once I managed to remove it and plug it back in the charge started without issues and the car charged all night at full rate without further intervention.
I’ve not knowingly had this issue before, so I’m putting it out to the masses. Is this an issue you’ve noticed when the temperatures are (very?) cold and you plug the car in hours before the charge starts? Could a build up of frost in the plugged in plug cause an issue during the charge start causing it to error out until it is removed and plugged in? Or is there an issue with my cable/plug? It’s a tethered Zappi, so can’t easily test another cable.
