PT Chery Sales Indonesia held a campaign 'Extrem Challenge Chery Battery Test' with the theme Revolution of Safety. This step is taken to answer public doubts and questions regarding the durability of Super Hybrid (CSH) Chery technology.

The event, which took place at PIK 2, Chery transparently proved the resilience and security of the TIGGO 8 CSH battery system through a rigorous sea water immersion test for 48 hours. The test follows the success of a series of extreme challenges in China, including spiral rollovers, dual-vehicle collisions, and the challenge of surviving for more than 48 hours in a 7-car stack pressure test.

It is an honor for Indonesia, because it is lined up as the first country on an international scale to conduct extreme battery tests. This test was attended by journalists from abroad, both from Malaysia and Thailand. As a country with a tropical rainforest climate, Indonesia has high rainfall and often causes flooding that poses a high risk of water exposure to battery immersions for vehicles.

Head of Brand Department of PT. Chery Sales Indonesia, Rifkie Setiawan, said the company understands consumer concerns about battery delays and safety in hybrid vehicles, especially in extreme conditions such as floods.

"By choosing Indonesia as the location for testing sea water immersions for 48 hours without stopping, we want to show transparently that CSH technology has been designed with the highest safety standards. This is a form of our commitment that 'safety is true luxury' that can be enjoyed by every family around the world," he said, when met at PIK 2, Tuesday, June 17.

Various scenarios from resilience when it hit floods to safety issues when the car was submerged in water, all answered with extreme testing that lasted for two full days. These challenges far exceed standard water resilience assessments, as the extraordinary conductivity and corrosive nature of seawater can accelerate metal corrosion and degradation of inflation at levels that far exceed exposure to ordinary rainwater.

In extreme humidity conditions, conventional batteries face critical safety hazards, including short circuits, leaks, and even fire incidents that pose a serious threat to driving safety. In line with its strong commitment to the Indonesian market and the adaptive development strategy "In Somewhere, For somewhere", Chery has chosen to carry out an innovative extreme test of CSH battery resistance in Indonesia. This initiative is then an answer to consumer concerns regarding battery safety in flood-prone and high humidity conditions.

After going through extreme 48-hour sea water immersions, the battery system will undergo comprehensive testing on the highway. The innovative approach of "seawater immersion + real-world driving evaluation" not only strictly validates the battery sealing system's resistance to corrosive fluids, but also thoroughly reviews the performance of insulation, structural integrity, and charging/depletion stability. Shows the ability of battery systems to survive, even from the most extreme environmental challenges.

Global Initiative, Extreme Testing Titled 'Mission Impossible'

The extreme CSH battery testing is part of a global initiative titled "Mission Impossible", where Chery consistently redefines safety technology constraints. Various other extreme tests have been and will be carried out in a number of countries, spanning all critical scenarios such as rollingovers in the desert, traversing rivers, to the challenge of climbing the ice peak. This made Chery the first automotive manufacturer from China to carry out comprehensive safety tests abroad in six extreme environments, including very cold, hot, dry, wet, high-speed scenarios, and heavy terrain. The entire extreme testing sequence was designed to transform what was previously considered 'Musthil in safety technology', becoming a real capability of CSH technology.

For information, the battery embedded for the 8 CSH Tiggo model uses a Lithium Iron Phosphate (Li-Po) battery with a capacity of 18.3 kWh which has IP68 Waterproof certification. By pocketing this certification, it proves its resilience to water and dust, and is able to operate normally in the extreme temperature range from -35$C to 60$C. The pinned battery is also able to make Chery TIGGO 8 CSH cover a distance of up to 90 Km in full EV mode.
