Title:

QUICK-CHANGE POWER BATTERY ASSEMBLY CAPABLE OF DELAYING HEAT DIFFUSION, AND ELECTRIC VEHICLE

Document Type and Number:

WIPO Patent Application WO/2022/242084

Kind Code:

A1

Abstract:

The present invention relates to the technical field of thermal runaway of batteries. Disclosed are a quick-change power battery assembly capable of delaying heat diffusion, and an electric vehicle. The quick-change power battery assembly comprises at least one battery module arranged in an accommodating cavity of a lower box body assembly, cross beams are respectively arranged on two sides of the battery module, and integrated baffles and elastic devices are arranged at two ends of the battery module, respectively. Disclosed in the present invention are a quick-change power battery assembly capable of delaying heat diffusion, and an electric vehicle, so that quick replacement of a battery module can be realized, and time is saved. Moreover, a harmful battery module can be separated from the whole vehicle in the first time when thermal runaway of the battery happens, so that the property safety of passengers is effectively ensured, the thermal runaway of the battery is effectively delayed, the safety of the battery assembly is ensured, the lightweight design of the assembly is realized, and the research and development cost is reduced.
