Abstract

The invention relates to a battery pack with an anti-collision safety protection structure, in particular a battery pack to prevent fire in case of collision or crash of an electric vehicle and avoid explosion of the battery. The battery pack with multilayered structure provided by the invention consists of two or more single-layer battery packs, and is characterized in that: the two or more single-layer battery packs realize physical solid joint and electric connection through at least two or more groups of up and down matched metal hooks and pins matching with the metal hooks. When the electric vehicle is collided, huge impact force triggers and promotes a cutting system matching the battery pack with multilayered structure to break a breakable insurance inserted rod and drive the pin to take off from a gap preset at the side of the metal hooks; and the damage process can always be ahead of the collision damage process, so as to realize early fire proof and explosion proof, minimize probability of secondary disasters of the collided electric vehicle, and lower the degree of secondary disasters to the minimum.

Description

[0001] 【Technical field】

[0002] The invention relates to a battery pack with an anti-collision safety protection structure, in particular to a battery pack for preventing electric vehicles from igniting and battery explosion when being hit or crashed.

[0003] 【Background technique】

[0004] At present, the safety performance of electric vehicles is low. Particularly prominent is the "on May 26, 2012, BYD taxi caught fire after being collided". There are many reasons for it, but for the safety design under extreme conditions, it should become a problem that is paid attention to. We have learned from our blood that when a serious accident occurs with an electric vehicle, people may be injured by the impact, and at the same time may lose their lives due to secondary fires and explosions.

[0005] However, after searching, there are few safety technologies that can effectively prevent or avoid secondary disasters caused by batteries to prevent electric vehicles from being ...
