China has introduced new electric vehicle (EV) battery safety standards that came into effect on July 1, 2026. The new regulations are considered the toughest EV battery safety rules in the world.
They focus on reducing the risk of battery fires, improving passenger safety, and making electric vehicles more reliable. The rules apply to both battery systems and the overall safety of electric vehicles.
Rule 1: Batteries Must Not Catch Fire or Explode
The biggest change is the new requirement that EV batteries must not catch fire or explode, even if one battery cell suffers a thermal runaway. Earlier regulations allowed batteries to catch fire as long as the vehicle warned passengers at least five minutes in advance.Under the new standard, manufacturers must stop fires and explosions from happening in the first place. This shifts the focus from warning passengers to preventing dangerous situations completely.
Rule 2: New Mandatory Safety Tests
Battery makers must now pass two additional safety tests before their products can be approved. One test checks how the battery performs if the underside of the vehicle is hit by a rock or another object on the road.The second test evaluates battery safety after repeated fast-charging cycles. These tests are designed to reflect real-world driving conditions and ensure batteries remain safe throughout their life.
Rule 3: One-Touch Emergency Power Cut-Off
China also requires every electric vehicle to have a physical emergency switch that disconnects the high-voltage battery within one second. Older systems relied mainly on software, which could stop working if the vehicle was badly damaged in a crash.The new hardware-based switch works independently and helps reduce the risk of electric shock or fire during emergencies.
Impact 1: Higher Costs for Manufacturers
The stricter safety standards will increase battery production costs. Industry experts estimate battery pack costs could rise by 15–20%, adding around 3,000 to 5,000 yuan (about $440–700) per vehicle.Large companies that invested in safer battery technology earlier are expected to handle the changes more easily, while smaller manufacturers may struggle with the extra costs.
Impact 2: LFP Batteries Could Gain Market Share
Experts believe Lithium Iron Phosphate (LFP) batteries will benefit from the new rules because they are naturally more stable and less likely to overheat than many other battery types.Since they require fewer changes to meet the new standards, more automakers may choose LFP batteries in future electric vehicles.
