I have my original charge cord connected to 240 20a (6-20? converter)It's about 3 months. Then it resets the home charging. Just went L2 to avoid it. Put in a 240, 20 amp circuit and use the standard L1 EVSE.
My manual says:According to the manual, it says:
The Charge Limit Preference setting
resets to the Reduced 8 amp setting
each time the vehicle is driven
