Xiaomi SU7 vs Tesla Model 3 Charging Speed Comparison
Q: Why does the Xiaomi SU7 standard version charge significantly faster than the Tesla Model 3 despite having similar voltage platforms?
A: The Xiaomi SU7 standard version achieves a 15-minute fast-charging capability of 350 km (CLTC) on self-operated chargers, outperforming the Model 3 Rear-Wheel Drive Refresh version by 100 km under the same conditions. This is attributed to three key factors:
The SU7’s “Super 400V” platform incorporates a full-domain silicon carbide design with a peak voltage of 486V, compared to the Model 3’s 394V peak voltage. Higher voltage enables greater charging power at identical current levels.
The Modena architecture optimizes charging curves for efficiency across varying conditions.
An advanced thermal management system maintains optimal battery temperature for faster charging, regardless of seasonal temperature extremes.
