OMG, just STOP! Front and back break lights are 31 watts, combined (23 and 8, and yes, I had to look that up). An electric car’s battery is over 100,000 watt-hours so that means that the break lights could be powered for over 1,000 days. The AC is a whopping 100 times more powerful than that, 3 kw, so it can be cycling on (compressor activated) for only 330 hours, or 13 days. That is so many times more longer than a gasoline engine, maybe a couple dozen!
