No different than gas vehicles running out of fuel.
Do the math and let's say theres even 50 percent charge of a 60kwh pack...and you just blast a 1000w of heat constantly....thats still 30 hours of heating at 1kw of power lol.
Gas vehicles burn .25 to .5 gallons per hour so uh...that 16 gallon tank completely topped off is 'only' 32hours. Half the tank and down to 16hours.
Just as a point of contention. Its hard to find an EV that is only gonna pull 1000w using the heater.
My EV doesn't have a heatpump and the resistive heating pulls up to 8KW warming up the cabin on a cold day.
I keep a 12v heated blanket around to save power. (no heated seats/steering wheel)
Heated seats are where the real power savings come in.
Webasto would like to have a word. "..can operate for up to 22 hours on less than one gallon of fuel.."

Those are aftermarket products for use in heavy vehicles, not something that's present (or usable) in passenger cars.
They are pretty common in passenger cars too, google 'standheizung' or 'stationary heater' and you'll find a ton of them. You might not realize that that is what it is. On cars sold in the Nordics and some German brands it is just a checkbox during the order process.
It's quite normal in colder climates, but mostly in Diesel cars. I had it in my VW Multivan. I've never heard of anyone installing Webasto in their EV.
There are all sorts of China knockoffs of them going up and down the size scale.
