12500 Tesla cars reported that there was little difference between DC fast charge and AC slow charge on battery life.

CTOnews.com August 29 news, at present in the electric vehicle industry, many consumers and the media agree that: DC DC fast charge is more harmful to the battery, AC AC slow charge can relatively prolong the service life of the car battery.

However, Recurring Auto recently conducted an in-depth survey of more than 12500 Tesla cars in the US market, and found that there is little difference in the impact of DC and AC on battery life, and the battery life curves of the two ways are statistically similar.

CTOnews.com note: this report tracked 4400 Tesla Model Y models and 6300 Model 3 models, and compared the decline curves of battery health when the DC fast charge ratio was more than 90% and less than 10%, indicating that the curves of the two charging methods were statistically similar.

The report points out that extreme temperature, too high voltage or too low voltage cause more damage to battery life than AC / DC charging methods. Recurring believes that electric vehicle manufacturers should strengthen their heat dissipation and voltage systems so that their batteries can have a longer service life.
