Why is the battery capacity of the Xiaomi SU7 Ultra smaller than that of the Xiaomi SU7 Max?

Question

The SU7 Ultra uses a track-specific high-power battery pack. Considering the needs for high power and lightweight design, the total energy capacity is slightly reduced.

Accepted Answer

The Xiaomi SU7 Ultra is equipped with a track-specific high-power battery pack. The cells use CATL's Qilin II, a chemical system designed specifically for high performance, offering stronger charging and discharging capabilities. Currently, the battery capacity of the Xiaomi SU7 Ultra comprehensively considers the needs for high power, lightweight design, long range, and ultra-fast charging. While overall performance is fully enhanced, the total energy carried is slightly lower compared to the Xiaomi SU7 Max.
With a peak performance of 1548 horsepower, the SU7 Ultra can still provide a range of 630km. Compared to the Model S Plaid, while the range is almost identical, the power output has increased by over 50%, fully demonstrating the technological leadership of the Xiaomi SU7 Ultra in energy efficiency management.
