What is the specific purpose of the 'bulletproof coating' on the bottom of the Xiaomi SU7 Ultra battery pack?
The bottom of the Xiaomi SU7 Ultra's battery pack adopts a 'bulletproof coating' with tank armor-level protection, which can effectively prevent cell damage caused by foreign object impacts or scraping during incidents such as underbody scraping.
Compared to traditional PVC coatings, the 'bulletproof coating' offers 10 times better tear resistance, 13 times better puncture resistance, 10 times better scratch resistance, and 10 times better adhesion (corrosion resistance).
Notably, based on the powerful performance of the 'bulletproof coating,' the Xiaomi SU7 Ultra successfully passed the extreme scenario serial tests for power batteries (track-level) conducted by CATARC and obtained the 'New Energy Vehicle Underbody Scraping Protection Certification.'
