Collision with a 242mm-tall obstacle at a speed of 30 km/h: TIGGO7 CSH Survives Mexico's Battery Scratch Test With Minimal Structural Harm
In a significant step forward for battery safety technology, Chery's flagship model, the TIGGO7 CSH, has successfully completed an extreme battery scrape test in Mexico City. On July 29, 2025, the vehicle underwent a direct impact against a 242 mm-high obstacle at 30 km/h with 30mm of overlap depth, demonstrating the resilience of the Guardian Battery system.
Key features of the Guardian Battery system that contributed to this success include:
- Instant 2-millisecond power cutoff capability: This quick isolation of the battery in case of impact or fault enhances safety, ensuring a rapid response to potential hazards.
- Robust structural design: The lithium iron phosphate blade battery offers enhanced mechanical stability and resistance to physical damage during impacts. The successful Mexico battery scrape test is a testament to this robustness.
- IP68-rated durability: This rating ensures protection against environmental factors that could compromise battery integrity during and after impact.
- Wide operating temperature range (-35°C to 60°C): This feature maintains battery reliability under varied conditions possibly encountered during crashes or accidents.
These features allow the Guardian Battery system not only to withstand direct mechanical shocks but also to maintain safety and operational integrity by rapidly cutting off power and protecting against environmental degradation.
Following the impact, the TIGGO7 CSH showed only minor surface scratches on the battery casing. The battery pack maintained excellent structural integrity, showing minimal bottom deformation. No signs of electrolyte leakage, fire, explosion, or smoke were observed, further emphasising the safety of the system.
The TIGGO7 CSH's underbody armor, made of 780MPa high-strength steel and featuring a chainmail-inspired structural design, also played a crucial role in absorbing the impact.
Chery's battery safety technology is being used to turn its vision of "Let everyone enjoy five-star protection" into a reality for customers worldwide. The TIGGO7 CSH's global safety challenge tour, which has stopped in Mexico after evaluations in China and Indonesia, is showcasing this industry-leading technology.
Chery is positioning itself as a leader in battery safety technology and is accelerating its global hybrid market expansion. The company is the first Chinese automaker to conduct comprehensive extreme safety validation overseas, validating its vehicles under six extreme global conditions, including extreme heat, humidity, and rough terrain.
High-visibility displays at Dubai International Airport proclaim Chery's core safety philosophy: "Safety, for Family." This philosophy is at the heart of Chery's commitment to providing top-tier safety features for its customers.
