The Xiaomi SU7 electric sedan demonstrated impressive battery durability. Over 18 months, the car traveled 265,000 km, maintaining a residual energy storage capacity of 94.5%.

What is known

The data published by CarNewsChina belongs to SU7 Pro owner named Feng. He drives an average of about 600 km per day.

The car is equipped with a 94.3 kWh battery. With an average consumption of 18 kWh per 100 km, the battery has gone through approximately 506 full charge-discharge cycles. The actual number of charges is likely higher, as partial cycles are more often used.

Most automakers provide an 8-year warranty or 150–160 thousand km for batteries with allowable degradation of 20–30%. In the case of the Xiaomi SU7, the mileage already exceeds these values by about 65%, with a capacity loss of only 5.5%.

The story went viral on Chinese social networks and attracted the attention of Xiaomi CEO Lei Jun. Feng himself plans to reach a mileage of 600,000 km in three years and notes that he has already saved more than 100,000 yuan (about $14,300) on fuel compared to an internal combustion engine car.

Although this is about only one specimen, this case shows that modern electric vehicle batteries can significantly exceed conservative warranty expectations. This is especially important for a brand that entered the car market just two years ago.
