Chery has successfully completed the second phase of its Global Safety Challenge, showcasing the toughness of its hybrid battery technology in a bold test conducted in Indonesia.
The test, which is part of Chery’s “Revolution of Safety” initiative, focused on proving that its Chery Super Hybrid (CSH) battery can survive and perform even after prolonged exposure to extreme conditions—like floods common in tropical regions.
As part of the demonstration, two CSH hybrid batteries were submerged in seawater for over 53 hours in a one-metre-deep tank. This intense test simulated real-world situations like flash floods, especially in countries like Malaysia and Indonesia where such events are frequent.
Once removed from the tank, one of the batteries was reinstalled into a Chery TIGGO 8 CSH and driven down a steep ramp, with Chery Sales Indonesia Vice President Zeng Shuo behind the wheel—proving it remained safe and functional.
“This test proves our battery’s ability to resist corrosive elements and maintain structural integrity under extreme conditions,” said Rifkie Setiawan, Head of Brand and Marketing at Chery Sales Indonesia.
Unlike standard waterproof tests, Chery’s seawater immersion test presented a much tougher challenge. Seawater’s high salt content accelerates corrosion, making it far more damaging than regular rain or floodwater. Yet, Chery’s battery passed the challenge without any sign of leakage, fire, or short circuits.
The TIGGO 8 CSH uses an 18.3 kWh Lithium Iron Phosphate (LFP) battery, trusted by over a million users worldwide. Certified with IP68 water and dust resistance, it can withstand extreme temperatures ranging from -35°C to 60°C and delivers up to 90 km of pure electric range. Thanks to its fast-charging capability, it can recharge from 30% to 80% in just 20 minutes using a CCS2 charger.
What sets Chery’s battery apart is its Guardian Battery Technology, which includes a specially engineered “Chainmail” structure. This provides extra protection with 14 structural anchor points, enhancing the SUV’s chassis strength by 7%. Multiple layers of thermal and insulation protection—10 at the base, 15 on the sides, and 16 thermal layers—add another level of safety.
The battery’s resilience has already been proven in China through a series of intense tests, including crash simulations, drop tests, salt exposure, and rollover evaluations.
This battery test campaign highlights Chery’s regional strategy of designing vehicles to suit local environments. Southeast Asian countries like Malaysia and Indonesia face unique challenges such as flash floods and high humidity. By pushing its technology to the limit in real-world conditions, Chery aims to offer peace of mind to drivers in these regions.
Following the successful Indonesia test, Chery will take the next leg of its Global Safety Challenge to Mexico. There, the TIGGO 7 CSH will be subjected to an underbody scraping test in mountainous terrain to assess its durability on rough roads and performance at high altitudes.
Chery plans to expand this safety campaign to other regions, including South Africa and Brazil, with each location testing the battery’s performance under different environmental pressures. The goal: to set a new global standard in safety for electrified vehicles.
