In 2021, Citizens United for Consumer Sovereignty, a South Korean consumer group, said that the driving range of most EVs drops by up to 40% in cold temperatures when the batteries need to be warmed up, citing data from the country’s environmental Tesla suffers the most. Ministry.
Last year, the KFTC fined German carmaker Mercedes-Benz and its Korean unit 20.2 billion won for falsely advertising gas emissions of its diesel passenger vehicles.
The challenge to electric vehicle performance in extreme temperatures is widely known, although EVs are popular in markets such as Norway, where four out of five vehicles sold last year were battery-powered, led by Tesla.
A 2020 study of all 4,200 connected EVs built by Canada-based telematics provider Geotab found that most models had similar declines in range in cold weather, mainly because the battery is also used to heat the car for the driver and passengers. goes.
The study found that above 20 °C the average EV outperformed its specified range, but at minus 15 °C the average EV was only 54% of the rated range.
