The gm portable charger has two pigtails for using either 120v level 1 or 240v level 2 charging. My complaint is that the gm charging unit will default to 120v level1 charging without any fault/warning indication if one phase of the 240v circuit fails. I had a 240v dedicated service installed so that I could charge my ev at 240v level 2 charging rates. The charging rate didn't seem to improve after plugging the charger into the 240v outlet, but I assumed that was due to current limitations of the gm portable charging unit. I happened to check the charging rate as displayed on the infotainment unit and discovered that I was actually charging at "120v level 1" even though I was plugged into the 240v outlet. I discovered that a fuse had blown on one of the phases of the service and after analyzing my electric utility bills realized that the fuse must have blown immediately. I didn't check the fuses before because the charger light was on and I assumed everything was ok. I've uploaded some photos of the electrical fault. Being a new ev owner and naive to charging rates and levels, I was unaware of the issue. The pigtails for the gm portable charger should have an 'identifier' circuit that allows the charger to determine if the service connection matches the expected capabilities and provide some type of fault or warning indication.
I have purchased the autel energy evse for my vehicle and had it installed by certified electricians in my garage. The unit malfunctions frequently and requires it to be restarted. The unit is hard wired and and the only way to reset it is to turn the breaker off and back on, as instructed by the manufacturer. Nev specifically says that using the breaker as a switch is no recommended. The purpose of the breaker is a power interruption device in case of an electrical fault. Using it as a switch to turn power off and back on could prematurely wear it out which creates a fire risk. The manufacturer has explicitly instructed me to create a fire hazard in my home to be able to use their product. This is a serious safety hazard.
The car battery caught fire!.
