Chery has taken hybrid batteries up the safety ladder in SEA’s harsh climate
Chery has successfully concluded the second phase of its Global Safety Challenge with a hybrid battery test in Indonesia, setting a new standard for vehicle safety in tropical climates. This milestone highlights the resilience of the Chery Super Hybrid (CSH) battery system, which will also be introduced in Malaysia.
As part of its “Revolution of Safety” initiative, Chery submerged two CSH batteries in a 1 metre deep seawater tank for over 53 hours. This test simulated harsh, flood-prone environments common in Southeast Asia. Conducted in the presence of the media, the demonstration ended with one of the tested batteries powering a TIGGO 8 CSH down a steep ramp.
Moreover, the drive showcased the battery’s continued performance after prolonged seawater exposure. “This test is part of a broader campaign to redefine automotive safety. It validates the battery’s resistance to corrosion, electrical insulation, structural integrity, and stability under extreme environmental conditions.” said Rifkie Setiawan, Head of Brand at Chery Sales Indonesia
Unlike standard waterproof tests, seawater immersion also poses greater risks due to its high conductivity and corrosiveness. The CSH battery’s success proves it can withstand Southeast Asia’s toughest conditions, preventing issues like short circuits, leakage, or fire. At the core of the TIGGO 8 CSH is an 18.3 kWh Lithium Iron Phosphate (LFP) battery, featuring IP68 waterproof and dustproof certification.
On top of that, it operates efficiently in temperatures from -35°C to 60°C and supports fast charging via CCS2, achieving 30% to 80% in 20 minutes. Chery’s Guardian Battery Technology includes a Chainmail Safety Structure with 14 anchor points, boosting chassis strength by 7% and resisting forces up to 200 kN.
The system also incorporates multi-layer insulation for enhanced protection. This achievement reflects Chery’s “In Somewhere, For Somewhere” strategy, designing vehicles for local climates. With Southeast Asia’s unpredictable weather and frequent floods, Chery’s real-world safety testing demonstrates a strong commitment to customer protection.
Looking ahead, the Global Safety Challenge continues in Mexico, where the TIGGO 7 CSH will undergo underbody tests on rugged highlands. Chery also plans further evaluations in South Africa and Brazil, as it aims to establish a new global benchmark in new energy vehicle safety. Congratulations to Chery on this monumental achievement.
