Valery, is this one of the "minor" bugfixes that you are reporting fixed below? I'll flash the firmware to be the newest, also so it gets power cycled.
But since it takes a month to reproduce the error, I won't know if it's fixed for a month when I go to use my car and realize it isn't charged.
Valery, let me know if you are already aware of this and/or what debugging steps you recommend.
I haven't rebooted it yet, so if there's a way to hook up debug output without resetting it, I can still do that.
Thanks Jay - since it seems to be related to rain, I might suspect GFI trip due to leakage. If water gets into any part of the energized system and creates a leakage to ground, this would be expected. Note that it does not have to be at the plug - could be somewhere else in the car, as well (although unlikely).
If it is indeed a GFI-related trip, there is not much we can do besides just disabling it altogether (not a great idea) or reducing the sensitivity of it (right now it's set to trip at ~10ma RMS). To reduce the sensitivity, you would need to make hardware change (add a parallel resistor to R5). You would also need to change sensitivity constant in firmware 'readV' function as the same sensor network is used to sense the AC voltage level.
