Chery battery defies its "watery grave" for over 50 hours

On 17 June 2025, Chery commenced the second stage of its Global Safety Challenge in Indonesia, focusing on the "extreme humidity" scenario within its six-dimensional safety evaluation system (heat, cold, dryness, humidity, high-speed, and rough terrain). This rigorous test validated the moisture and corrosion resistance of the "Guardian Battery" in the brand’s Chery Super Hybrid (CSH) technology.

After 53 hours and 51 minutes of continuous saltwater soaking, the battery had zero leakage, zero short circuit, and no signs of thermal runaway. It maintained structural integrity and passed all technical validations for electrical insulation. Once installed in the vehicle, it started successfully on the first attempt and delivered stable power throughout the road test, completing the rigorous challenge with zero anomalies.

CSH technology's "Guardian Battery" features IP68-rated waterproof and dustproof certification, an ultra-fast 2ms power cut-off response, an ultra-wide operating temperature range from -35°C to 60°C, and a 24/7 real-time health monitoring system.

Looking ahead, Chery will conduct a rigorous underbody scraping test in the Mexican market to further evaluate the safety performance of the CSH technology.
