Teslas last better in the cold batteries deteriorate faster

Teslas last better in the cold – batteries deteriorate faster in hot climates, a study shows

Lithium batteries are generally quite heat-loving, as they significantly reduce the remaining charge when it is cold and only by gradually warming up can some of their performance be restored. A new study has shown that prolonged exposure to elevated temperatures also harms Tesla traction batteries – in fact, they “wear out” faster in hot climates.

As explained Electrics Citing recurring research data based on data from more than 12,500 Tesla Model Y electric vehicles manufactured in the United States in 2020 or later, their traction batteries lose remaining capacity more quickly over time when operated in climates where the ambient temperature exceeds 30 degrees Celsius. In areas of the U.S. with cooler climates, Tesla electric vehicles have, on average, a higher remaining traction battery capacity after several years of operation, although this difference is only a few percent.

The chemistry of Tesla’s lithium batteries appears to have a more beneficial effect on the lifespan of the battery itself when it is not constantly exposed to elevated temperatures. A recent study on the battery life of electric vehicles of this brand also showed that the frequent use of Supercharger brand fast charging stations does not have a significant impact on shortening the life of traction batteries. At least with regard to the operating conditions of Tesla electric vehicles, another common myth has been debunked. The company produces only part of the traction batteries used in the production of cars independently, in other cases it purchases them from Panasonic, CATL, BYD and LG Energy Solution, so the data obtained when processing statistics on Tesla electric vehicles is used with reservations can. be extended to the behavior of traction batteries in other brands of electric vehicles.
