Abstract

The invention discloses a quick-change power battery assembly capable of delaying heat diffusion and an electric vehicle, and belongs to the technical field of thermal runaway of batteries. The quick-change power battery assembly comprises at least one battery module arranged in an accommodating cavity of a lower box body assembly, two sides of the battery module are provided with cross beams respectively, and two ends of the battery module are provided with an integrated baffle and an elastic device respectively. According to the quick-change power battery assembly capable of delaying heat diffusion and the electric vehicle, quick change of a battery module can be realized, and time can be saved; and in the first time of thermal runaway of the battery, a harmful battery module can be separated from the whole vehicle, 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.

Description

technical field [0001] The invention discloses a quick-change power battery assembly and an electric vehicle that delay thermal diffusion, and belongs to the technical field of battery thermal runaway. Background technique [0002] At present, the development prospects of new energy vehicles are very broad. New energy vehicles have the advantages of high energy efficiency, zero emissions, no pollution, high specific energy, low noise, and high reliability. As the main energy storage component of the new energy battery vehicle, the power battery system mainly ensures the driving of the vehicle, the power demand of high and low voltage components, the recovery of braking energy, and the energy regulation of the hybrid engine system. The safety of the power battery assembly has always been the key to its quality. With the rapid development of the demand for high-energy and high-power battery assemblies, a series of safety issues have been brought about by the battery assembly....
