Despite the proven success of electric vehicles in even the coldest climates, many Canadians still harbor concerns about EV range and charging during winter. To address these anxieties head-on, the Canadian Automobile Association (CAA) conducted a comprehensive real-world cold weather test involving a dozen different EV models. The results offer valuable insights and practical strategies for maximizing EV performance in the Canadian winter, showcasing the resilience and adaptability of these vehicles.
The CAA clubs across Canada put a variety of EVs to the test in temperatures ranging from -7 to -15 degrees Celsius, driving them until the battery was completely depleted. While the test vehicles did experience a reduction in range compared to their official all-weather estimates, the findings were within a manageable 14 to 39 percent decrease across the board. This real-world data provides a more accurate understanding of cold-weather range impact than generalized figures, empowering potential EV adopters with realistic expectations.
Furthermore, the CAA investigated the impact of cold temperatures on charging speeds. During a 15-minute session on a DC fast charger, the tested EVs achieved an average battery charge gain of 28 percent. This demonstrates that while charging might be slightly slower in frigid conditions, DC fast charging remains a viable option for quickly replenishing range, even in the heart of winter. The CAA’s findings help to dispel myths about EVs and charging in cold weather, offering concrete data to inform consumer decisions.
Beyond the test results, the CAA also provides practical tips and techniques for protecting EV batteries and maximizing range during the winter months. These include recommendations for EV-specific winter tires, the beneficial practice of keeping the vehicle plugged in when not in use, preconditioning the cabin to conserve battery power, driving smoothly to avoid rapid acceleration, utilizing regenerative braking, and opting for heated seats and steering wheels over the cabin heater. By implementing these simple strategies, Canadian EV owners can confidently navigate winter conditions and enjoy the many benefits of electric driving.
