Chery's Guardian Battery Survives Over 53 Hours in Indonesian Ocean

Chery's Guardian Battery: A Test of Durability in Extreme Conditions

On June 17, 2025, Chery Automobile Co., Ltd. launched the second phase of its global safety competition in Jakarta, Indonesia. This phase focused on evaluating the "extreme humidity" scenario within Chery's comprehensive six-dimensional safety assessment system, designed to test heat, cold, dryness, humidity, high speed, and uneven terrain.

The spotlight was on Chery's innovative "Guardian Battery" used in their Super Hybrid vehicle (CSH), which faced an extraordinary test of endurance. Over the course of 53 hours and 51 minutes, the battery was continuously submerged in saltwater, a challenging environment that many products cannot survive. However, the Guardian Battery emerged unscathed, showcasing zero leakage, no short circuits, and exhibiting no signs of thermal loss. Remarkably, it maintained structural integrity and passed all electrical insulation verification tests.

Immediately following the test, the battery was reinstalled in the vehicle, where it successfully started on the first attempt and provided stable energy throughout the driving test, further demonstrating its reliability in demanding scenarios.

Impressive Features and Safety Standards

The Guardian Battery boasts an IP68 certification for waterproof and dustproof capabilities, reflecting its robustness. Additionally, it features an ultra-fast energy cutoff response of merely 2 milliseconds and is designed to function within a vast operating temperature range from -35°C to 60°C. This battery is equipped with a real-time state monitoring system available 24/7, ensuring comprehensive safety backed by advanced intelligent technologies.

In terms of passive safety protection, the TIGGO8 CSH is enhanced with a shield made from high-strength steel with a tensile strength of 780 MPa, significantly boosting the vehicle's overall safety profile. This kind of safety innovation places Chery in direct competition with automotive leaders like Volvo, emphasizing their commitment to technological advancement and user-centered design.

During the event, the spacious "5+2" seating arrangement and the vehicle’s V2L (Vehicle-to-Load) ecosystem garnered significant attention from the attendees. The convenience of third-row seats that fold flat with the push of a button, combined with a class-leading trunk capacity of 1,930 liters and additional storage spaces totaling 36 liters, make the TIGGO8 CSH an ideal choice for family journeys, ensuring comfort and ease on every trip.

Continuing Commitment to Safety and Innovation

Chery’s ongoing commitment to enhancing safety technology was on full display during this event. By conducting rigorous global safety challenges, they confirm the reliability of their products and their dedication to providing safer mobility solutions to customers worldwide. Following the successful testing phase in Indonesia, Chery plans to conduct a stringent underbody scratch test in the Mexican market, seeking to further evaluate the safety performance of the CSH.

As they look to the future, Chery aims to uphold meticulous standards of safety and innovation, ensuring that their vehicles not only meet but exceed industry expectations. Through these challenges and research, Chery reinforces its determination to deliver reliable, state-of-the-art mobility solutions to a global audience, exemplifying their role as a pioneer in the automotive industry.
