Xiaomi SU7 Ultra: A Track-Ready Electric Beast with High-Power Battery
Xiaomi’s highly anticipated SU7 Ultra electric SUV is making waves with itstrack-ready performance, thanks to a high-power battery pack directly derived from its prototype.
The latest edition of Xiaomi’s Ask Me Anythingseries, released on November 2nd, provided insights into the SU7 Ultra’s features, addressing questions regarding its external speakers and the unique characteristics of itstrack-ready battery.
External Speakers: A Symphony of Sound and Safety
The SU7 Ultra boasts two external speakers, including a new 40W speaker at the rear. This addition caters to the vehicle’s high-performance sound system, delivering a thrilling and immersive driving experience. The external speakers also serve a safety purpose, providing audible cues about the vehicle’s status, such as when the car is reversing or turning. While the speakers can be turnedon and off, Xiaomi recommends using them only in appropriate environments to avoid disturbing others. Currently, the external speakers do not support music playback or other customizable content.
Track-Ready Battery: Power, Cooling, and Safety
The SU7 Ultra’s track-ready battery is designed to conquer the demanding conditionsof the racetrack. It delivers exceptional power output, rapid charging, and robust cooling capabilities, making it a true performance powerhouse.
Here’s a breakdown of the key features:
- High Power Output: The battery boasts a peak voltage of 897V and a maximum discharge power of 1330kW, resulting in a maximum discharge rate of 16C. Even with only 20% charge, the battery can deliver a maximum power of 800kW, exceeding the performance of some full-power electric vehicles on the Nürburgring.
- Advanced Cooling: The battery utilizesa high-conductivity electrolyte and a high-porosity porous electrode, minimizing internal resistance to just 0.25mΩ, the lowest in the industry. This significantly reduces heat generation during operation. The battery pack also incorporates the industry’s strongest dual-sided active cooling technology, achieving a peak heat exchange power of18kW. This ensures optimal operating temperatures, allowing the SU7 Ultra to complete two laps at the Nürburgring without overheating.
- Rapid Charging: Xiaomi’s Atomic Charging and Near-Cold Source Ear Cooling technologies enable an ultra-high charging rate of 5.2C. This means the battery can be charged from 10% to 80% in just 11 minutes, allowing for quick returns to the track.
- Uncompromising Safety: The track-ready battery inherits the safety features of Xiaomi’s CTB (Cell-to-Body) integrated batterytechnology. This includes cell inversion technology, 14 layers of physical protection, 7.3m² dual-sided cooling, 170 pieces of aerogel, 17 layers of high-voltage insulation protection, and a vehicle-cloud collaborative safety warning system. Even under extreme conditions, such as 55℃ high temperature with full charge, individual cell thermal failure will not lead to thermal propagation.
Xiaomi has further enhanced the track-ready battery with additional protective structures, which will be detailed upon the official launch.
The Xiaomi SU7 Ultra’s track-ready battery is a testament to Xiaomi’s commitmentto pushing the boundaries of electric vehicle performance. With its exceptional power, rapid charging, and unwavering safety, the SU7 Ultra is poised to become a formidable contender in the world of high-performance electric vehicles.
