The Canadian Vehicle Affiliation (CAA) performed a winter vary check on 14 electrical autos (EVs) to guage their efficiency in chilly temperatures, particularly between 19.4 and 6.8 levels Fahrenheit (-7 to -15 levels Celsius).
The outcomes revealed that every one examined EVs underperformed in comparison with their marketed driving vary, with losses starting from 14% to 39%. The CAA check commenced with absolutely charged autos being pushed till they may not transfer, adopted by a recharge session at a 350-kilowatt quick charger.
Among the many autos examined have been seven of Canada’s high ten best-selling EVs. The Chevrolet Silverado EV and Polestar 2 emerged as the highest performers, each experiencing a 14% lower in real-world vary. The Silverado EV, with a spread estimate of 450 miles (724 kilometers) from Pure Sources Canada (NRCan), drove 283 miles (456 km) earlier than depletion, regardless of beginning the check with a 74% cost.
As compared, the Polestar 2 has an NRCan vary of 276 miles (384 km) and lined near 255 miles (410 km) earlier than working out of energy. The Tesla Mannequin 3, one other fashionable alternative, displayed a big 30% distinction between its official vary of 363 miles (584 km) and its actual efficiency of roughly 255 miles (410 km).
A abstract of the real-world efficiency of the autos is as follows:
| Mannequin | Rank | Distance on a Single Cost | Official NRCan Vary | Distinction |

| Chevrolet Silverado EV | 1 | 283.3 miles (456 km) | 449.8 miles (724 km) | -14%* |
| Tesla Mannequin 3 | 2 | 254.7 miles (410 km) | 362.8 miles (584 km) | -30% |
| Polestar 2 | 3 | 238.6 miles (384 km) | 275.8 miles (444 km) | -14% |
| Kia EV9 | 4 | 216.8 miles (349 km) | 270.2 miles (435 km) | -20% |
| Volkswagen ID.4 | 5 | 210 miles (338 km) | 290.8 miles (468 km) | -28% |
| Chevrolet Equinox EV | 6 | 209.4 miles (337 km) | 318.7 miles (513 km) | -34% |
| Ford Mustang Mach-E | 7 | 207.5 miles (334 km) | 300.1 miles (483 km) | -31% |
| Honda Prologue | 8 | 207.5 miles (334 km) | 272.7 miles (439 km) | -24% |
| Ford F-150 Lightning | 9 | 183.9 miles (296 km) | 320 miles (515 km) | -35%* |
| Kia Niro EV | 10 | 177 miles (285 km) | 252.8 miles (407 km) | -30% |
| Hyundai Ioniq 5 | 11 | 162.8 miles (262 km) | 254.7 miles (410 km) | -36% |
| Toyota BZ4X | 12 | 158.4 miles (255 km) | 252.2 miles (406 km) | -37% |
| Volvo XC40 Recharge | 13 | 154.1 miles (248 km) | 254.1 miles (409 km) | -39% |
The Kia EV6 didn’t take part within the vary check because of a complication. Changes have been made to account for the Chevrolet Silverado EV beginning at 73% cost and the Ford F-150 Lightning at 89%.
Comparable findings have been reported by Recurrent, which analyzed over 18,000 EVs and concluded a winter vary lack of 11% to 37% in comparison with favorable circumstances. After the driving assessments, the EVs have been related to a 350 kW charger (besides the Tesla Mannequin 3) to watch the charging time from 10% to 80% cost. Nonetheless, it’s unsure whether or not the batteries have been preconditioned previous to charging.
The charging check outcomes are as follows:
| Mannequin | Rank | Miles Added in 15 Minutes | Time to Cost (10% to 80%) | Common Charging Pace |
|—————————–|——|—————————–|——————————|————————|
| Tesla Mannequin 3 | 1 | 127.3 miles (205 km) | 37 minutes | 96 kW |
| Chevrolet Silverado EV | 2 | 123.6 miles (199 km) | 32 minutes | 233 kW |
| Chevrolet Equinox EV | 3 | 81.3 miles (131 km) | 42 minutes | 100 kW |
| Polestar 2 | 4 | 74.5 miles (120 km) | 40 minutes | 94 kW |
| Volkswagen ID.4 | 5 | 69.5 miles (112 km) | 34 minutes | 104 kW |
| Ford F-150 Lightning | 6 | 67.7 miles (109 km) | 45 minutes | 128 kW |
| Kia EV9 | 7 | 65.2 miles (105 km) | 33 minutes | 139 kW |
| Volvo XC40 Recharge | 8 | 55.9 miles (90 km) | 40 minutes | 87 kW |
| Ford Mustang Mach-E | 9 | 44.1 miles (71 km) | 46 minutes | 85 kW |
| Hyundai Ioniq 5 | 10 | 39.7 miles (64 km) | 45 minutes | 80 kW |
| Kia EV6 | 11 | 36 miles (58 km) | 43 minutes | 85 kW |
| Kia Niro EV | 12 | 21.7 miles (35 km) | 77 minutes | 36 kW |
| Toyota BZ4X | 13 | 11.8 miles (19 km) | 92 minutes | 33 kW |
The Honda Prologue’s information was excluded from the charging check because of an error. All autos utilized 350 kW chargers, apart from the Tesla Mannequin 3, which charged at 150 kW to adjust to compatibility necessities.
Regardless of being charged at a decrease price, the Tesla Mannequin 3 was the quickest, gaining 127 miles in quarter-hour, requiring solely 37 minutes to achieve an 80% state of cost with a median velocity of 96 kW. The Silverado EV adopted carefully, reaching 123 miles of vary in quarter-hour and shifting from 10% to 80% cost in 32 minutes at a median of 233 kW. The Equinox EV secured third place with 81 miles added in quarter-hour and a median charging velocity of 100 kW.
It’s essential to notice that the chilly climate negatively impacts battery efficiency because of adjustments within the chemistry, making power switch tougher. Charging charges can be affected by low temperatures except the battery is preconditioned previous to the session. Preconditioning entails utilizing battery power to heat up the battery, optimizing it for charging, although it leads to some power loss throughout the course of.
