Problems solved by technology

Solve the "extreme conditions" such as high-speed collision or high-speed collision of electric vehicles, under the conditions that the car body may be severely deformed or high-speed collisions cause serious internal parts collisions, etc., under the action of strong external forces or other emergency treatment devices, Minimize or promptly eliminate the role of the battery pack as a major source of danger, and reduce the explosion or fire of the battery pack due to compression deformation or severe impact

Embodiment Construction

[0029] As shown in Figure 1, the entire structure consists of a set of batteries 101, a set of battery connecting pieces 102, a frame 106, a sealing strip 105, a top cover 104, two pole protection covers 103, and two battery pack management boxes 107 and 18 M5 fixing screws 108, voltage sampling wiring harness, temperature sensor and wiring harness thereof.

[0030] Such as figure 2 , image 3 , what is described is a battery pack with a multi-layer structure composed of three single-layer battery packs 21; each single-layer battery pack 21 has multiple groups such as figure 1 The battery pack shown is composed; there are three sets of metal hooks 22 fixed by pins 31 between each single-layer battery pack 21; the spatial layout of the metal hooks 22 is: both ends are positive electrode metal hooks 22 and negative electrodes The metal hook 22 is a non-conductive metal hook 22 in the middle. image 3 As shown, between the first and second layers of the single-layer battery ...

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 ...
