KATHMANDU: Chery has unveiled a new battery safety assurance program that combines stricter engineering standards with a lifetime battery protection policy.
Under the new plan, the company will replace the vehicle if a battery-related thermal runaway causes the car to catch fire.
The initiative is part of Chery’s latest consumer protection strategy and will apply to the brand’s current and future electric passenger vehicles. It also supports upcoming plug-in hybrid models, including the Fulwin A9 sedan and Fulwin T7 crossover.
Chery says its battery pack is engineered to withstand 1,500 joules of underbody impact, which is 10 times higher than China’s latest regulatory requirement.
The company also claims the battery passed a 10-pin simultaneous puncture test without smoke or fire. Additional validation included crushing, water immersion, and nail penetration tests, with no thermal runaway recorded.
To improve battery quality, Chery uses a highly controlled manufacturing environment. The cell production line maintains extremely low dust levels to reduce the risk of internal short circuits, while a 100-meter magnetic levitation logistics system minimizes contamination during assembly.
The battery production system has also been designed to support future solid-state battery technology.
Chery has filed a patent for sulfide-based solid-state electrolytes and says its long-term target is to achieve an energy density of up to 600 Wh/kg, significantly higher than current lithium-ion batteries.
According to the company, a test fleet of 43,000 vehicles has covered more than 1.2 billion kilometers without a single recorded battery fire, providing confidence before expanding to semi-solid-state and full solid-state battery production.
The announcement comes as Chery faces slowing sales in its home market.
