Yesterday, Chery Auto Malaysia performed a safety test on the Chery Super Hybrid (CSH) battery used in the Tiggo 7 PHEV and Tiggo 8 PHEV. The company subjected the 18.3 kWh LFP pack to a massive fire, with temperatures reaching over 1,000 degrees Celsius, but the battery remained largely unscathed. At the event, the company lit up 36 litres of petrol (no Budi95 quota was used, we checked), then lowered the said battery over the fire, leaving it there for 80 seconds. As you’d expect, the casing was singed, but the pack itself was intact without any electrical failure or uncontrolled deformation and, crucially, there was no thermal runaway, so the fire remained controlled. In fact, a company spokesperson said that having subjected another battery to the same test for a dry run, it opened the casing to discover that the cells themselves had not been touched by the flames. Chery claims the battery features a heat-resistant construction that, even in the event of ignition, prevents fires from propagating, and it can withstand temperatures up to 95 degrees Celsius. It also has a built-in, high-strength crossmember to protect it in an accident. The hybrid system routinely checks the battery for instances of thermal runaway and, if one is detected, a pyrotechnic safety switch (PSS) will disconnect the battery within two milliseconds. This is meant to slow down any fire that occurs, giving occupants more time to escape. “Safety is at the core of our development process. Beyond meeting regulatory requirements, we conduct rigorous and extreme validation tests, and we demonstrate these tests publicly to help people understand the technology, the standards behind it, and why we are confident in its safety,” said Chery Corporate Malaysia executive vice president Men Lin Bo. Chery has performed several durability and safety tests on the CSH battery, including subjecting a Tiggo 9 PHEV to a head-on collision and a rollover in China. It then submerged the battery in seawater for over 53 hours in Jakarta; that battery was then reinstalled into a Tiggo 8 PHEV and the car managed to drive on without issue. The company also performed an impact test in Mexico, with a Tiggo 7 PHEV surviving an underbody scrape with a low bollard. Other tests include an offset frontal crash in South Africa and even gunshots from multiple angles using a rifle in Ecuador.
