In an effort to remove battery fires, China’s Ministry of Business and Info Know-how (MIIT) has launched new rules that considerably exceed present security requirements for next-generation battery expertise.
Beginning July 1, 2026, producers will probably be required to make sure that their batteries can forestall fires and explosions even after experiencing inner thermal runaway. This marks a considerable shift in regulatory expectations for battery security.
From subsequent yr, all batteries produced in China will bear rigorous testing to ensure that they don’t ignite or explode throughout cases of thermal runaway. Beforehand, rules solely mandated a warning sign to be issued 5 minutes previous to potential fireplace or explosion, however this measure is now thought-about insufficient.
To reinforce security additional, batteries should even be subjected to impression testing on the underside of the cells, evaluating the protecting capabilities of their casings. Moreover, they have to stand up to 300 DC fast-charging cycles with out incidents of fireside, explosion, or short-circuiting.
Business consultants consider these new security rules surpass any current necessary testing necessities globally, promising a major improve in security requirements.
Responding to those adjustments, Chinese language producer CATL expressed its help for the brand new requirements, noting that it has already developed batteries that adjust to these rules. CATL first launched its No Thermal Propagation (NP) expertise in 2020.
Based on CATL, “The brand new normal will successfully cut back the danger of energy battery fires after collisions in new power autos, thereby higher defending customers’ lives.”
These new battery rules come within the wake of a tragic incident in China involving a Xiaomi SU7, which caught fireplace after an accident, ensuing within the deaths of three feminine college college students. As investigations into the incident proceed, it’s believed that lawmakers felt compelled to deal with public considerations concerning the danger of spontaneous combustion in electrical autos.
