How will I stay warm (and for how long) in an electric car if I get stuck in another snowstorm?
In: Technology
Depends on the car, and it’s battery capacity. Per car and driver magazine, using the environmental controls at a moderate level, with no heated seats, increases energy consumption by 17% of the energy used by the drive system for simply driving, at 70mph, in a Tesla model 3. So that at least suggests, to me, that you’d probably be able to get approximately ~5-6 times the driving duration, compared to battery duration at 70mph, if just using the environmental systems and NOT driving. So if the car normally drives 3 hours, at 70, you’d get ~15 hours just heating?
Take this with a grain of salt, however, as this is conjecture based on their fairly rudimentary testing procedures!
Personally, I’d count on not more than 8-10 hours, and pack accordingly for your locale.
