The battery life of Tesla Model Y and other models is severely reduced at low temperatures, Consumer Reports test results show

According to news from this site on August 2, it is known that electric vehicles will be adversely affected in cold weather. However, even under the current warmer conditions, some all-electric models are not performing as well as expected in the United States

To understand the impact of cold weather on battery range, the nonprofit Consumer Reports conducted a The claimed cruising ranges of Tesla Model Y Long Range Edition, Ford Mustang Mach-E Long Range Edition, Hyundai Ioniq 5 and Volkswagen ID.4 Pro S were tested under three temperature conditions

The range performance of these electric vehicles in cold weather is not surprising, but the Tesla Model Y performs best among the four vehicles. Even when outside temperatures aren't low enough to affect the battery, it still falls short of the EPA's 326-mile range.

# In Consumer Reports testing, the Model Y was tested for sustained cruising at 70 mph (112 km/h) on the highway. After a round trip of 142 miles (228 km), the actual range dropped to 186 miles (299 kilometers)

The electric Mach-E excels in terms of official range, reaching 270 miles (434 kilometers), while in cold weather (average temperature -8 degrees Celsius), the range is 188 miles (302 kilometers). The Hyundai Ioniq 5 has an EPA range of 256 miles (412 km) and an actual cold-weather range of 183 miles (294 km)

Volkswagen ID.4 During the same period, its EPA-rated range is 240 miles (386 km), with actual cold-weather range of 170 miles (273 km)

Although in mild weather conditions of 18 degrees Celsius, all four electric models The car's range has improved by about 50-70 miles, but is still lower than the official figure

Subsequently, Consumer Reports conducted tests in warm weather of 29 degrees Celsius, and the results showed that some models Battery life meets or exceeds EPA standards. For example, the Mustang Mach-E and ID.4 have a range of 275 miles (442 kilometers) and 256 miles (412 kilometers) respectively, while the Ioniq 5's range is 2 miles (4.8 kilometers) less than the official estimate

However, in this warm weather, the Model Y's range is only 274 miles (441 kilometers), which is much lower than the EPA's estimated 326 miles (524 kilometers)

The Tesla Model Y is the lightest of the four models, more than 500 pounds lighter than the heaviest ID.4, and about 200 pounds lighter than the Ioniq 5 with a similar-sized battery. The Ioniq 5's battery capacity is 72.6kWh, Tesla estimates it at 81kWh

To ensure accurate range data, Consumer Reports fully charges the electric vehicle before each test and maintains its charge. is 100%. The same route was then driven on adaptive cruise control settings at 70 mph, with mechanisms such as energy recovery set to minimum.

Engineers recorded and analyzed each test after the car returned to the test center. The remaining driving range displayed by an electric vehicle. By referring to the ratio of miles used during the trip to the number of miles driven, engineers extrapolate the total range for a specific trip. At the same time, engineers also compared this ratio with the mileage per mile at the battery percentage. According to Consumer Reports, in order to simulate typical user usage scenarios, the batteries of all models were not completely exhausted. Because even oil-fueled vehicles are rarely driven without oil.
