Tesla faces a €2 million fine for an undisclosed reduction in driving range in cold weather

South Korea fined Tesla 2.85 billion won (2.1 million euros) for exaggerating driving range electric vehicles (EV).

The country’s antitrust regulator says customers were not informed that the driving range was getting shorter low temperatures.

Tesla is accused of exaggerating “driving ranges”. cars on a single charge, their fuel efficiency compared to gasoline vehicles, as well as the efficiency of recharges” on its official local website from August 2019 until recently, the Korea Fair Trade Commission (KFTC) says.

Last year KFTC fined German automaker Mercedes-Benz and its Korean unit fined 20.2 billion won (€15 million) for false advertising related to emissions from diesel passenger cars.

How much does EV driving range decrease in cold weather?

The range of cars of the American manufacturer of electric vehicles is increasing rapidly cold weather up to 50.5 percent compared to how they are advertised online, according to the KFTC.

Tesla comment could not be obtained immediately.

On its website, Tesla shares tips for winter driving, such as pre-preparing vehicles with external power sources and using the updated Energy app to monitor energy consumption, but does not mention the loss of driving range in temperatures below zero.

In 2021, the South Korean consumer group Citizens United for Consumer Sovereignty reported that the reach of most electric vehicles a drop of up to 40 percent in cold weather when batteries need to be warmed up, with Tesla suffering the most, according to data from the country’s environment ministry.

However, the challenge of electric vehicle performance in extreme temperatures is well known electric vehicles are popular in markets such as Norway, where four out of five vehicles sold last year were battery powered, led by Tesla.

Why does EV range drop in cold weather?

2020 study of 4,200 connected electric vehicles An all-brands expert from Canadian telematics provider Geotab found that most models experienced a similar drop in range in cold weather, mainly because the battery also serves to heat the car for the driver and passengers.

Average slightly above 20 degrees Celsius EV exceeded its claimed range, but at minus 15 degrees, the average EV was only 54 percent of the rated range, according to the study.

Cold temperatures also slow down the chemical reactions that store and release electricity in the lithium-ion batteries that typically power electric and hybrid cars. This causes battery work less efficiently.

What are the advantages and disadvantages of electric vehicles?

Electric vehicles are widely praised as being better for the environment than internal combustion engine cars. There is no exhaust system and therefore no contamination.

Range, availability of charging points and cost are factors that discourage drivers from buying electric vehicles. But as infrastructure across Europe is improving and green initiatives are imperative withdraw cars with internal combustion engines, electric vehicles will become mainstream.

However, electric vehicles have their own environmental disadvantages. While the vehicles themselves do not emit pollutants, the batteries that power the engines are made of them minerals that have to be extracted, which has a huge ecological impact on our planet.

While electric vehicles are not perfect and probably never will be, they are widely regarded as the best option available to reduce vehicle emissions and fossil fueldependency, especially as technology continues to evolve.
