I'm wondering what types of range extension methods could be easily added to an EV.
Scenario: I'm going to drive 900km/560mi and it's -10 outside (I do this multiple times per year).
I want a cosy room temperature inside the cabin.
- How can I ensure I waste as little range as possible on heating, so that I don't risk having to make e.g. 2 stops instead of one?
- More critically, if I get stuck in traffic for several hours because of an accident, I need some way to ensure I don't freeze to death in my EV as I'm standing still and the battery runs out.
It seems these two things should be solvable with a single solution: a plug-in space heater to be used in emergencies and for maximizing cold weather range. The space heater could be e.g. a kerosene burner or similar. But for best effect it should of course "plug in" to the car vents.
Is this a thing? Or is heating the passenger compartment such a trivial use of energy anyway if the car is insulated, that it doesn't make a difference? In a concrete scenario: If I drive a model 3 and have 100km battery left, and I have 20km to my planned charging stop half way through my journey. Suddenly traffic stands still because of an accident and it's freezing outside. How long will the "100km" charge maintain the 30K temperature difference while still having 20km left?
