The Gen2 Mobile Connector uses a Dallas/Maxim 1-wire digital sensor in the AC outlet adaptor to sense temperature, and also let the EVSE know which type of outlet it's connected to. If this serial digital signal doesn't reach the EVSE for whatever reason, it will limit amperage. One way to test

Thanks Phil Apparently when raining or hot the negative temperature coefficient thermistor tells the uP (analog input drops when resistance drops) causes it to go into current fold back mode. The fix looks like coating the board with conformal coating to prevent moisture ingress (Tesla forgot

I would try removing the wall side plug. It is possible over time for it to become partially unseated. Reseat it may fix the problem. Phil H. On Thu, Jul 20, 2023, 2:12 PM Mark Hanson via EV wrote: > Hi folks > Does anyone know how to take apart a Tesla mobile charge controller? > After 65K

Maybe it's one of the temperature sensors on the plug side or the AC inlet side, either the sensor itself or the wiring/terminals gone bad or dirty that interconnects to the EVSE? https://teslamotorsclub.com/tmc/threads/wheres-the-temperature-sensor.212002/ Pages 11 & 12: You must be having

Hi folks Does anyone know how to take apart a Tesla mobile charge controller? After 65K miles charging it dropped to 16A, initially only when the sun shined on it (heated internal thermistor), but now it’s all the time. It may be fuzzy relay contacts. I’ve seen small charge controllers like
