Are usually charge my car at my work shop. I only have a 30 amp breaker so I set the charge limit to 29 A. It always worked fine before, but now after about an hour the charge limit drops to 16 A, and then about 30 minutes later iit jumps up to the 32 A max. I find I must constantly walk out to the car and reset the charge limit. This just started happening. Any idea why or how to fix it? So far, the breaker has not flipped but I don’t want to accidentally start a fire or something.
