Yesterday after having the car and charger checked out by the dealer, and both getting a clean bill of health, I got a full charge at from their 60A charger. The MINI service reps Michael and Fred from Morristown MINI were very helpful even though this was the first MINI E they'd had to diagnose a problem for, as it turned out the backline BMW tech they contact for MINI E problems was already aware of the problem, having read my blog post about it, to All MINI/BMW employee's reading this thank you for your help and supporting a great program, its good to know your reading this.
Anyway, I returned home and tried to charge the car again, but when I plugged the car into the garage outlet the MINI E's charge light only came on for a second before going out while the charger's charge light came on and stayed on. The MINI service reps had suggested I try plugging into other outlets, but also had said I should not use a extension cable as it might overheat, I have a 12 gauge extension cable rated at 120V 15A which I very much doubt will overheat. but I wanted to try what I could do without it. I found that if I pulled the car out and backed it into my garage, I could just barely reach a outlet in the kitchen without an extension cable, I plugged it in and.. POP the kitchen GFI triped. Then I started looking for somewhere else to plug in and noticed the laundry and dryer, The single outlet for both of these was not on a GFI, was the only outlet on that curcuit and had a 20A breaker rather then the regular 15A ones on most of my curcuits. So I plugged it in there, and it worked, was able to charge the car completely overnight, though its still very slow about 3% charge in one hour, at that rate we're looking at 33 hours to charge the car from 0% to 100%.
So it looks like we need to aviod GFIs though it did charge for me the first night on a GFI curcuit, this could be a big problem as most modern Garages and outdoor plugs have to be GFIs. The problem could also be the wiring, I got a wire tester and checked the outlets but it said they were all good, I'm going to try replacing one of the GFI's temporally with a normal outlet to verify whether its the GFI or the wiring, causing the charging to fail. In the mean time I guess no laundry is getting done while charging :)
