The Xiaomi CEO, Lei Jun, always looking for new ways to impress, showcased the durability of the SU7 Ultra sports car’s coating by dropping a watermelon from the 6th floor of the factory.
Impressive Battery Specs
The SU7 Ultra is powered by a 94 kWh NMH battery pack produced by CATL, which accelerates from 0-60 mph in less than two seconds. Xiaomi has worked hard to make the ternary nickel battery as safe as possible for impacts. The structural chassis pack features a strong multilayer shell made of high-strength steel beams, alongside an active cooling system that uses wide surface and aerogel insulation.
Advanced Cooling Technology
The Xiaomi SU7 Ultra’s battery is part of CATL’s latest generation Qilin batteries, boasting dual large-surface active cooling. This is similar to the system BYD recently highlighted in their 1MW Han L sedan. This design aids in heat dissipation, which is crucial for safety during rapid 5C charging sessions, and extends the lifespan of the battery cells by keeping them cool under stress.
The aerogel surrounding each cell prevents the spread of issues from one cell to another, while the 7.8 m2 active cooling system has plates on both sides of the prismatic cells to significantly increase the total cooling surface area. To safeguard against side impacts, the CATL Qilin battery pack is structurally enhanced and coated with what is referred to as “bulletproof” material.
Durability and Market Presence
In the SU7 Ultra’s battery pack, this coating increases scratch and tear resistance by ten times and puncture resistance by thirteen times.
Xiaomi, primarily recognized for its smartphones, home electronics, and consumer gadgets like Bluetooth speakers, is now leveraging its reputation for value to enter the electric vehicle market, which is gaining traction. Lei Jun’s strong work ethic and ambitious nature have made him something of a cult figure among Chinese business leaders, who liken him to Elon Musk.
The proof of this innovation was evident when Lei Jun stood on the 6th floor of Xiaomi’s car factory and dropped a watermelon wrapped in the same coating used for the SU7 Ultra battery. The result was that the watermelon bounced off the asphalt below without breaking apart, demonstrating the level of safety Xiaomi aims for in its racing car batteries during impacts.
