Xiaomi Details the Battery of Its First Electric Car, the SU7
The technology company Xiaomi has revealed the complete data of the battery pack that will power its debut in the automotive sector, the SU7 electric sedan. The solution employs an innovative CTB (Cell-to-Body) architecture, where cell modules form part of the vehicle's own structure. This approach aims to reinforce rigidity and make the most of the available space for occupants. 🔋
Architecture and Key Specifications
Developed in conjunction with the specialist CATL, the battery uses lithium-iron-phosphate (LFP) chemistry, known for its stability and durability. With a net capacity of 101 kWh, the system is prepared to withstand extremely high charging powers thanks to its 800-volt platform.
Main Performance Features:- Extended Range: Promises up to 800 kilometers under the CLTC homologation cycle with a full recharge.
- Ultra-Fast Charging: Can recover approximately 220 km of range in just 5 minutes and reach 80% of its capacity in about 15 minutes.
- Structural Integration: CTB technology eliminates traditional packaging, fusing the cells with the chassis to gain interior space and robustness.
The 800V architecture is fundamental to achieving these charging times, positioning the SU7 in the premium segment of electric vehicles.
Focus on Safety and Thermal Control
Xiaomi has placed special emphasis on protecting the integrity of the battery pack. To do this, it has implemented a bidirectional thermal management system that can both heat and cool the cells according to usage conditions, thus optimizing their efficiency and lifespan.
Passive and Active Safety Elements:- Reinforced Structure: A high-strength frame surrounds the pack to protect it from impacts or deformations.
- Ventilation and Passive Suppression: Incorporates channels designed to dissipate heat and systems that act in case of a thermal incident.
- Exhaustive Testing: The manufacturer claims that the unit has passed rigorous tests simulating collisions, crushing, and environmental stress.
Market Positioning and Availability
With these technical credentials, Xiaomi seeks to compete directly with other established manufacturers in the high-performance electric sedan segment. The SU7 is already on sale in the Chinese market, although the strategy to introduce it in Europe and other international regions has not yet been finalized with an official date. The brand's bet focuses on offering a convincing balance between practical range, charging speed, and, above all, safety guarantees for the user. 🚗
