Actually not the case at all.
Much like watching Star Trek, your EV can send it’s energy to the Climate Support, to keep you at 70F for 18 hours, while keeping more than a 50 mile range for the motors. Further, while we gas car users frequently run down the road with a half tank of gas or less; while EV owners typically will have a charge station in their garage, and will leave their home with 80% or a full charge every time they leave.
If you are in the ditch, with a gas engine, your engine’s gas consumption turns the transmission, runs the alternator, water pump, and the entire car; whether the wheels turn or not. If you are out of gas, it’s going to get very cold; and many cars won’t let you run the heat for 18 hours.
But it don’t seem to add up. How many watts does vehicle need to keep the cab at 75 degrees F for 18 hours?
How many watts continuously? And that is all converted to heat.
Both the good and the bad — because a gasoline engine is inefficient and produces a lot of excess heat which can be exchanged in the cooling system, a person can be very cozy warm in the winter. An EV is a lot more efficient with less excess heat (wasted energy) so the passengers freeze. I picture a 2000 watt heating element plugged into the battery. I don’t know how it is done in an EV but it is probably something that simple.
At least that is my theory and I am sticking to it. :)
