Zero charge rate in the cold

.

The UMC uses the resistance of the pilot pin to the ground in the adaptor to determine the charge allowable. By adding a resistor to this value one can fool the UMC to charge at a rate larger than that is safe.

You are brave to do this. Might this damage the UMC over time?

Funny, I've been able to get rated at -15C drafting a tandem tanker at 107 kph.

Well there were 30km/h headwinds so if I wasn't close enough to the truck that would have been a major factor, and there was 5 of us in the car... I could be wrong, but the car seems to be much more efficient when I'm driving solo.

Well THAT would do it. Since most of the drag at highway speeds is due to aerodynamics, a 30 kph headwind will have an enormous effect on your range. Drafting the truck probably saved you a LOT of energy.

Worst case is that your house catches on fire (for any reason, doesn't have to be related to your charging setup) and your insurance company refuses to cover you because you modified a listed device to break the law (NEC rules are codified as law). I've seen it happen, unfortunately.

I drove home the other night in a very high, buffeting headwind with Cruise on, and it was fascinating to watch the power meter dance up and down in proportion to the headwind I was dealing with, even on perfectly level ground. A real visual confirmation of the aerodynamic effects.
