In a groundbreaking move within the electric vehicle (EV) landscape, Xiaomi, the Chinese tech giant, unveiled its proprietary 800V silicon carbide high-voltage platform during the Xiaomi Automotive Technology Conference on December 28. This significant development took place alongside the launch of Xiaomi EV Technology, as CEO Lei Jun articulated the company’s vision to ascend to the ranks of the world’s top five automakers.

Alongside the EVs, the conference also witnessed the launch of Xiaomi’s self-developed 800V silicon carbide high-voltage platform. According to Lei Jun, models that are currently over 500V can be referred to as 800V, and the Xiaomi SU7’s 800V platform has a maximum voltage of 871V.

In addition, the car’s 800-volt high-voltage battery pack was assembled over two years by thousands of engineers from Xiaomi and CATL; the battery cells were not created on their own. The CTB battery body integration technology, which Xiaomi developed in-house, is used in this battery. It is officially stated that the wire harness is reduced by 91%, resulting in a 3% reduction in wiring harness area, the volume efficiency reaches 77.8%, and the thickness of the battery pack + floor is 120mm.

The battery’s maximum power of 150kWh may accomplish a range of over 1,200km under CLTC conditions under the mature system. Similarly, the battery’s maximum power of 132kWh can achieve an endurance of over 1,000km under CLTC conditions.

In terms of safety, the battery also has the greatest cooling area in its class (7.8 m2), the first cell inversion technology in the market, 17 layers of high-voltage insulation protection, and 165 aerogel pieces for heat insulation. The car-cloud collaborative safety warning system, which Xiaomi Auto also supports, boasts 10 times the industry-level detection frequency, twice the national standard data volume, and round-the-clock cloud protection.
