Electric Car Winter Heater Test: EVs as the Solution to Cold Weather Problems

From Plug and Play EV.

(Edit Note: Temp conversions in Centigrade at 1:37 should be reversed.)

Following up on our initial test of how much energy a Bolt EV heater uses to keep the car toasty in freezing conditions (link below), we go overnight to monitor energy consumption when temps drop even lower. This is about as cold as it commonly gets in winter around Boston, so take that for what it is if you live somewhere far colder!

Starting just after 6pm, with ambient temperature at 19°F / -7°C and the pack at 90% state of charge, we precondition the cabin (i.e. heat up while charging), use 0.5 kWh while driving home, then sit idle overnight to lows of 6F / -14°C in the wee hours of the morning. The results are eye-opening and, again, intended to show how an electric car will perform sitting idle for rare emergencies in which cars cannot move and the occupants cannot just walk somewhere safe.

We also look to the future and how new EVs might be able to help others in emergency scenarios, such as vehicle-to-vehicle charging (V2L on Hyundai IONIQ 5, Kia EV6, and coming to VW ID.4) and power generation around 10 kW on upcoming electric trucks like the Ford F150 Lightning and Chevy Silverado EV. The former even offers a system dedicated to powering homes in emergencies, replicating the functionality of a combustion F150 EcoBoost seen during 2021Texas outages, without the complication of managing exhaust fumes.
