CTB Integrated Battery Technology combines the battery pack's upper cover with the vehicle floor to improve structural safety, body rigidity, and cabin space.
*Volumetric efficiency 77.8% = total volume of battery cells/usable energy-storage volume. *Data is from Xiaomi Auto Lab. Battery capacity testing condition: 1/3C. 150kWh and related parameters are designed values; actual values are subject to mass production.
Dual-Sided Cooling System with a 7.8m² Heat Dissipation Area Side-Mounted Aerogel Thermal Insulation
The battery features 17 layers of high-voltage insulation protection and a custom active cooling system. The dual-sided cooling system provides a heat dissipation area of 7.8m², providing exceptional heat dissipation. The sides of the battery cells are filled with 165 aerogel pieces that can withstand temperatures of up to 1,000°C.

Innovative Cell Inversion Technology Efficient and Safe
The inverted cell design places the pressure relief valve on the underside of the cell, allowing energy to be rapidly discharged downward in extreme conditions and helping improve cabin safety.
Vehicle‑To‑Cloud Safety Alert System ASIL D Safety Rating
Over 800 signals are tested per second, which is 2x the China GB standard volume, enabling 24-hour monitoring. In case of emergencies, Xiaomi Full-Stack Battery Management System cuts off the current within 4ms.
*Data is from Xiaomi Auto Lab. 10x refers to Xiaomi's data detection frequency of once per second, compared with the industry standard of once every 10 seconds. 2x refers to the detection data volume required by the China GB standard.
Ultra‑Rigorous Battery Tests Safety is everything
We conduct over 1,050 safety tests covering scenarios such as collisions, crushing, fires, overcharging, and immersion in water. The number of test items is 20x higher and the durability test duration is 96x longer than those required by the China GB standard. We strive to eliminate all possible safety concerns.
