Indonesia test shows battery resilience in high humidity,
reinforcing trust in Malaysian conditions
JAKARTA, 24 JUNE 2025 – Chery has successfully completed the second phase of its Global Safety Challenge – battery test campaign in Indonesia, marking a new benchmark in hybrid vehicle safety for tropical markets. The test demonstrated exceptional durability and real-world safety of the Chery Super Hybrid (CSH) hybrid battery — a technology that will also be available to Malaysian consumers.
As part of the ‘Revolution of Safety’ initiative, two Chery CSH batteries were submerged in a 1-metre-deep tank filled with seawater for more than 53 hours, simulating the corrosive and high-pressure conditions commonly found in flood-prone regions.
The test was conducted in front of local and international media and culminated in the battery being reinstalled into a TIGGO 8 CSH vehicle and driven down a steep ramp by Zeng Shuo, Vice President of Chery Sales Indonesia accompanied by Budi Darmawan Jantania, Director of Chery Sales Indonesia proving its operational safety even after prolonged seawater exposure.
“This battery safety test is part of a Global Safety Test campaign that reflects our commitment to continuously redefining the limits of automotive safety technology. Through the ‘seawater immersion and real-world driving evaluation’, we have validated the battery’s seal durability against corrosive liquids, and comprehensively examined its insulation performance, structural integrity, and charge/discharge stability. These results confirm that Chery’s battery systems are built to remain robust even under the most extreme environmental conditions,” said Rifkie Setiawan, Head of Brand Department of Chery Sales Indonesia.
The battery test also goes far beyond standard waterproof benchmarks—seawater’s high conductivity and corrosive nature significantly accelerate material degradation compared to rainwater exposure. The successful completion of this extreme test validates the CSH battery’s capability to operate safely in Southeast Asia’s harshest conditions, preventing risks such as short circuits, leakage, or fire.
Advanced Protection with Chery’s Guardian Battery Technology
Chery’s bold demonstration was not a gamble—it was backed by confidence in the robust technology protecting the TIGGO 8 CSH battery. Trusted by over a million families worldwide, the SUV uses an 18.3 kWh Lithium Iron Phosphate (LFP) battery, certified with IP68 waterproofing for resistance to water and dust. It remains operational across an extreme temperature range from -35°C to 60°C and delivers up to 90 km of pure EV range. The battery also supports fast charging via CCS2, reaching from 30% to 80% in just 20 minutes.
Its Chainmail Battery Safety Structure, designed with 14 safety anchor points, boosts chassis strength by 7% and can withstand extrusion forces up to 200 kN.
The protection system is reinforced by a multilayer insulation design—10 layers at the base, 15 on the sides, and 16 thermal layers.
This durability has already been proven in China through a series of extreme safety challenges, including spiral rollovers, dual collisions, a 7-vehicle stack test, 55 km/h intrusion test, 4.9-metre drop test, and 720-hour salt spray exposure.
