These loads can not be ignored, but I was surprised at how minor they are compared to the power needed to move a vehicle at speed.
The most juice I have ever given my truck was 350 amps. At 160 volts, that is over 55,000 watts. When I was working on my truck, I could keep the cab toasty warm with a little 500 watt ceramic heater. On a scorching day, a 500 watt ac unit can keep a 200 sq ft bedroom cool - the inside of a car would be an ice box. So you could run AC or heat for almost 2 hours on the same power I would pull doing 1 minute of acceleration up a decent grade at 45mph. The batteries can handle it
As for real cold weather, where water thrown from a pot freezes before it hits the ground? Easy. Charge that car up, put as much of your junk in the back as will fit, and drive south. Seriously, I dont know how you Northerners manage.
Anyway, I find this topic very interesting. I suspect that a very similar discussion has happened throughout history:
“No, your iron tool is not better than my pointy stick, look, there are sticks everywhere! I can just go pick up another one when it breaks!”
“No, your steam contraption is not better than my horse! I can breed more horses every year, and I dont have to dig up food for them!”
“No, your gasoline engine isnt better than my steam engine, it smells bad, and besides, there is a coal vendor on every corner!”
And so on
I think it is fair to recognize that after a lifetime lived with a technology, it might be too late for an individual to change their ways; but that doesnt make the technological transition itself a fools errand. I suspect that electric cars are going to be just like every major shift. At first the zealots will say “this will fix everything!” Then the masses will realize it is actually better and adopt it. And then finally the new problems that arise after the old problems are fixed will simply move the goalposts ahead, and the process will repeat.
