Firstly, the battery has to consume more energy at lower temperatures, as chemical reactions take place more slowly in the cold. Secondly, the interior, the windows and seats, the steering wheel and the battery itself all have to be heated using electrical energy from the traction battery. Heating is therefore a major energy guzzler. “This can be countered by bringing the vehicle to operating temperature prior to departure, while it is still connected to the charging station”, says expert Peter Schmid. He is the head of the “new mobility hub by AMAG” at Zurich Airport.
“E-vehicles have a lower range in winter”, confirms Peter Schmid. “If people can charge their car at home or at the workplace, this is not likely to be a problem. The most common types of electric cars can still cover 300 km in the winter too.” The average loss of range in winter is between 15-25%. In exceptional cases, a range loss of up to 30% is possible, but not with the newest-generation batteries.
