Extreme heat can reduce the range of an electric car by 31%, according to a report by Recurrent Auto, a company specializing in testing batteries for electric cars.
Recurrent experts have analyzed the battery readings of 7.5 thousand cars and found that at an air temperature of 27 degrees Celsius, the range is reduced relative to the maximum by almost 2.8%, at 32 degrees – by 5%, and at 38 degrees the drop can reach 31%.
At the same time, the data on the dynamics of charge consumption in conditions of 38-degree heat are extremely limited and need to be clarified, the company said, adding that if necessary, they will adjust the indicator on the basis of subsequent measurements.
The use of air conditioning, in turn, reduces the range only to a small extent. At the same time, reducing the temperature in the cabin by 7 degrees will require less energy than increasing it by 10 degrees.
