Chery's Battery Survives Over 53 Hours in the Indonesian Ocean
Chery's Remarkable Battery Challenge in Indonesia
On June 17, 2025, Chery embarked on the second phase of its Global Safety Challenge in Jakarta, Indonesia, centering on extreme humidity conditions that are crucial for evaluating the safety of its vehicles. The testing scenario mimicked severe environmental challenges, including moisture resistance and corrosion, playing a pivotal role in Chery's assessment of its innovative battery technology.
This intense testing, held in the salty waters of the Indonesian ocean, lasted for an impressive 53 hours and 51 minutes. Witnessed by industry reporters and officials, including Heri Prabowo from the Ministry of Transportation, the Guardian battery showcased remarkable resilience, demonstrating no leakage, no short circuits, and no signs of thermal runaway after prolonged exposure to water. After being submerged, the battery was successfully installed in a Chery Super Hybrid (CSH) vehicle, where it powered up on the first attempt, delivering stable energy throughout the road test and completing the stringent challenge without incident.
Impressive Features of the Guardian Battery
Chery's Guardian battery is equipped with an IP68 certification that ensures it is both waterproof and dustproof. It also features a rapid disconnection response time of just 2 milliseconds, enabling it to maintain enhanced safety. The battery is functional across an extensive temperature range, operating from as low as -35°C up to 60°C. Additionally, it offers a real-time battery state monitoring system, providing users peace of mind with 24/7 safety coverage.
Despite the challenging conditions, the CSH’s battery maintained its structural integrity, meeting all technical validations for electrical insulation. The testing not only reinforced the reliability of the Guardian battery but also raised the bar for expectations in automotive safety standards.
Holistic Vehicle Safety with TIGGO8 CSH
The TIGGO8 CSH model, associated with the battery, incorporates a sturdy high-strength steel shield beneath the vehicle, boasting a tensile strength of 780 MPa that significantly enhances overall safety performance. The vehicle's spacious ‘5+2’ seating arrangement, combined with a class-leading boot capacity of 1,930 liters and 36 storage compartments, underscored an ideal family travel experience. Furthermore, the vehicle comes with a powerful Vehicle-to-Load (V2L) capacity of 3.3 kW, ideal for outdoor activities and emergencies.
The ambitious safety endeavors made by Chery position it in a competitive light alongside industry leaders such as Volvo. This global safety challenge signifies Chery's ongoing commitment to advancing technological innovation, particularly in user-centered engineering.
Looking ahead, Chery plans further rigorous testing, including low scraping tests in the Mexican market, aiming to assess the performance and robustness of their CSH model. This future endeavor highlights Chery's dedication to delivering safer and more reliable mobility solutions to customers globally, solidifying its reputation within the automotive industry.
Conclusion
Chery’s successful testing of the Guardian battery in extreme conditions represents a significant milestone in automotive safety and reliability. As the brand continues to push the envelope in terms of technology and customer safety, the commitment shown during these challenges sets a promising precedent for future advancements in the electric vehicle sector.
