The Canadian Automobile Association (CAA) recently conducted a real-world winter EV performance test to examine the impact of extreme cold on electric vehicle (EV) range and charging. The test, which took place between Ottawa and Mont Tremblant in sub-zero temperatures, included vehicles representing over two-thirds of Canadian EV sales. The findings highlight significant range reductions and slower charging speeds, reinforcing concerns many Canadians have about EV performance in winter.
Key Highlights:
- EV range dropped between 14% and 39% compared to official estimates, with the Chevrolet Silverado EV and Polestar 2 performing best at only a 14% reduction.
- More than two-thirds of Canadians cite winter range loss as a major barrier to EV adoption.
- 65% of Canadian EV owners report experiencing reduced range in extreme cold.
- On average, EVs added 100 km of range in 15 minutes on a DC fast charger, but charging speeds varied greatly.
- The Tesla Model 3 charged the fastest, gaining over 200 km of range in 15 minutes.
- 53% of EV owners still prefer gas vehicles for long trips in extreme cold.
- CAA calls for a standardized EV labeling system that includes winter performance ratings.
The test involved 14 EV models across various segments, including sedans, SUVs, and trucks. Each vehicle was driven until its battery was completely depleted to measure real-world winter range. Charging performance was also analyzed, with results showing that cold temperatures significantly impact charging speed.
CAA also provided practical tips to help EV drivers optimize performance in winter conditions:
- Precondition the EV while plugged in to maximize range.
- Remove snow and ice to reduce weight and improve aerodynamics.
- Use heated seats instead of cabin heaters to conserve energy.
- Park indoors when possible to keep the battery warmer and improve charging efficiency.
The CAA EV Winter Test is part of the organization’s ongoing efforts to provide unbiased information on EV performance and help consumers make informed decisions. The full test results, including a breakdown of vehicle performance, are available through CAA’s EV Buyer’s Guide.
