Tesla EV performance in Alaskan winters: efficiency and charging insights

Study on Tesla EVs in Alaskan winters shows efficiency drops up to 69% when parked outside, but vehicles remain operational with heated parking benefits.
A study using real-world operational data has examined how Tesla electric vehicles perform during Alaskan winters. The research focused on temperatures as low as -40°C and their impact on efficiency, driving, and charging processes.
The findings reveal that EVs remain operational even in extreme cold, though efficiency drops significantly. The worst results came from vehicles left outdoors: when parked outside, efficiency decreased by up to 69% compared to warmer conditions. None of the studied EVs experienced failures that would make driving impossible.
Cars kept in heated spaces had clear advantages: they warmed up faster and maintained higher efficiency. Charging in severe cold was slower but remained feasible overall. The report authors recommend investing in covered, heated parking where possible. This helps minimize efficiency losses and reduces strain on the battery.
Overall, the study concludes that with proven practices, electric cars can be suitable transportation even for cold regions. It notes that further development of batteries and thermal management systems should make operating EVs in extreme climates easier.
