    Charged today at a friend's summer home. The only unusual thing about the location is the line voltage is pretty high; it started at 251V and went down to 244V under load. I charged for two hours the first time and everything was normal.

    When I returned later, when I plugged in it gave a message, which said approximately "Battery Voltage Low. May charge slowly at first. Recommend using MC240." It was charging at a whopping 7A.

    I cycled the slider on the UMC charge cable. The car charged normally.

    When I returned an hour later to drive the car, everything was charging normally. I went away for five minutes and as I returned I heard the "brap brap brap" of an error. This time it said, "Charging Problem - ID:920 Data 0x00080000". Cycled the plug again and it started working. Stopped it again and drove home. Seems to be charging normally at home.

    I got that once when my battery was very low. Only mine said use to use the MC120. So I switched to that and after several hours I went back to my UMC. Really could be a problem if that happened on a trip.

    Yeah, but I had 130 km range left...
