Tesla car battery life revealed: after three years, the actual battery life is only 64% of the official promotion

Recently, the data company Recurrent released a study on Tesla car battery life. The study conducted an in-depth analysis based on battery data from 12,198 Tesla vehicles, including 7,078 Model 3 and 5,120 Model Y vehicles. Using more than 1.6 million observational data points, Recurrent came to a striking conclusion: About three years after the vehicles were on the road, the EPA range of these Tesla vehicles only reached 64% of the officially advertised range.

#The data editor understands that this finding reveals the difference in display of electric vehicle range in actual use. Even in new condition, these vehicles can only achieve 70% to 72.5% of the advertised EPA range. This means that starting from the new car, there is a certain gap between the actual cruising range and the official data.

However, this problem is not unique to Tesla. Recurrent pointed out that the EPA's basic range testing method may be problematic because it does not fully account for the impact of temperature changes or high-speed driving (over 60 mph) on battery life. It also allows manufacturers to make adjustments to test results. This may result in a large difference between EPA mileage and actual usage. Therefore, it is necessary to adjust the EPA cruising range and actual usage. This may result in a large difference between EPA mileage and actual usage.

Although the 64% cruising range retention rate seems surprising, if we compare the cruising range of new cars with the cruising range after three years of use, the actual decline in cruising range is expected to be between 6% and 8.5% %between. This result is not too disappointing, but it still reminds consumers that when buying electric vehicles, they should pay more attention to the actual cruising range rather than relying solely on official promotional data.
