I haven't installed a private charging pile yet and frequently use DC fast charging. Will it damage the battery?
Please rest assured, it won't. Combining fast/slow charging according to your own charging environment and time plan is appropriate. The warranty and design life of the Xiaomi SU7 high-voltage battery comprehensively consider the impact of fast/slow charging, and typically have no impact on battery life. Regarding charging frequency, the Xiaomi SU7 can be charged as needed, but here are some suggestions:
In terms of material characteristics, the optimal charge usage range for ternary lithium batteries is 20%-80%. However, there is no need to strictly limit the charging upper limit to 80%; daily practice can vary based on actual situations. For example, charging to "above 80%" is more recommended for long-distance travel, and the battery charge upper limit can be conveniently adjusted on the vehicle control screen and the Xiaomi Auto APP.
If storing the vehicle for a long period, you can set a charging limit; we recommend setting it to 50%~80%.
