I read a thought provoking jab at EVs this morning, something I never considered. Not trying to stir anything up, but out of lack of knowledge, it makes me wonder.
Let's suppose ICE vehicles are gone and it's all EV.
I'm sure we have all been in a situation where there is a major issue on the road, a bad wreck, a weather problem, whatever. The highway is closed for many hours while they address the situation, perhaps even overnight or longer. And its January. You and everyone else is sitting there trying to stay warm and you have a 3 mile lineup of EVs with dead batteries....
How good are the heaters in an EV, and how much power do they draw?
How do you rescue hundreds of motorists and clear a highway full of dead battery vehicles?
Maybe the solution is simple and I don't see it...
In that kind of situation an EV is a pretty good place to be. AN EV heater keeping a car warm draws less than a KW. A typical EV has a 60 to 100 kWh battery. You could sit there warm and cosy for days with no problem. The upcoming half ton EV’s have batteries between 140 to 200 kWh. You could probably stay warm and comfortable for a week in those. Same in summer with AC. Doesn’t take much to keep a warm car warm or a cool car cool.
