The Real-World Winter Range Test of the 2025 Chevrolet Equinox EV
The Chevrolet Equinox EV has proven to be a popular choice among electric car enthusiasts due to its affordability and impressive sales figures. However, how does this electric crossover hold up in freezing temperatures? One brave owner decided to put the 2025 Equinox EV to the test by embarking on a real-world winter range test in cold Midwest weather. The goal was to determine how far the vehicle could travel on a single charge in sub-zero conditions.
The Test Setup and Performance in Freezing Temperatures
Equipped with an 85-kilowatt-hour battery pack and a dual-motor all-wheel drive system, the 2025 Equinox EV started the test with a full battery and an estimated range of 306 miles at a chilly -6 degrees Fahrenheit. Driving at a constant speed of 75 mph on the highway, the owner closely monitored the battery level and energy efficiency. The test revealed that at 52% state of charge, the vehicle had only traveled 69 miles with an efficiency of 1.5 miles/kWh. As the test continued, the efficiency slightly improved, but the battery warning indicator came on at 12% state of charge.
Range and Efficiency Results in Winter Conditions
The test concluded when the vehicle’s battery level reached 10%, indicating that 90% of the battery had been used for approximately 150 miles of highway driving. The average energy efficiency during the test was calculated to be 1.7 miles/kWh, resulting in an estimated remaining range of 19 miles. When considering the miles/kWh figure and the usable battery capacity, the theoretical maximum range in sub-zero temperatures at a constant speed of 75 mph was determined to be 144.5 miles, significantly lower than the EPA estimate of 307 miles.
Factors Affecting Electric Vehicle Range in Winter
It’s important to note that EVs experience a significant decrease in range in cold weather conditions, with estimates suggesting a 20% to 30% reduction in efficiency when the temperature drops below freezing. Additionally, driving at high speeds, such as over 70 mph, can further impact energy efficiency. While laboratory tests provide ideal conditions for range estimates, real-world driving experiences may vary based on weather conditions and driving habits.
Comparing Winter Range Test Results with Summer Conditions
A previous test conducted by Tom Moloughney showed that in warm weather conditions at 70 mph, the 2024 Equinox EV could exceed its EPA estimate with an average efficiency of 3.4 miles/kWh. This comparison highlights the significant impact that weather conditions can have on an EV’s range, making it crucial for drivers to consider these factors before embarking on long road trips in the winter.
Final Thoughts on Winter Electric Vehicle Range
Before setting out on a winter road trip with an EV, it’s essential to do thorough research, including checking for operational chargers along the way using resources like the PlugShare app. Unexpected disruptions in charging infrastructure can significantly impact travel plans. By understanding the effects of cold weather on an electric vehicle’s range and taking necessary precautions, drivers can have a smoother and more efficient winter driving experience with their EVs.
