Problems solved by technology
As the only energy source for electric vehicles, the power battery has many problems, such as high battery cost, poor safety performance, low energy density, short service life, heavy weight, and low space utilization. It is extremely important to improve the research
[0003] The safety of electric vehicles has received widespread attention due to many accidents of electric vehicle collisions and fires at home and abroad. The results of vehicle collision analysis show that during the collision process, the power battery module cannot effectively reduce the vibration frequency and amplitude, resulting in damage to the battery surface. Electrolyte leakage caused a short circuit and an electric arc ignited the vehicle

Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 A new type of collision-resistant power battery module shown includes a battery module steel case 1 and a cover plate 2, the battery module steel case 1 is a hollow cuboid structure, one end of the cover plate 2 and the battery module steel case 1 Connected by a hinge, the two can be rotated relative to each other, and the other end of the cover plate 2 is fixedly connected to the battery module steel case 1 by screws to form a whole. The battery module steel case 1 has a plurality of new single cells 5 inside. A spring set 3 is fixedly connected to one inner surface of the steel case 1 of the battery module, and the other end of the spring set 3 is connected to an insulating partition 4 .
[0014] The new single battery 5 is a hexahedron with a certain slope on one or both sides of the surface. The slope can increase the contac...

The invention relates to a novel collision-resistant power battery module. The module comprises a battery module steel shell and a cover plate, wherein the battery module steel shell adopts a hollow cuboid structure, a spring group is fixedly connected inside the battery module steel shell, the other end of the spring group is connected with an insulating partition board, a plurality of novel cells are placed in the battery module steel shell, and positive and negative electrode ports are formed in the cover plate. When the power battery module is collided or vibrated, the collision resistanceof the power battery is effectively improved, self-vibration absorption can be realized, the service life of the power battery can be prolonged, and the safety performance of the power battery can beimproved.
Description
technical field [0001] The invention relates to a novel collision-resistant power battery module. Background technique [0002] In recent years, with the increasingly serious air pollution, the tight supply of global oil resources and the enhancement of environmental awareness, pure electric vehicles have become more and more popular. At the same time, my country's national policy support for the electric vehicle industry has also greatly promoted the rapid development of electric vehicles. As the only energy source for electric vehicles, the power battery has many problems, such as high battery cost, poor safety performance, low energy density, short service life, heavy weight, and low space utilization. Research improvements are extremely important. [0003] The safety of electric vehicles has received widespread attention due to many accidents of electric vehicle collisions and fires at home and abroad. The results of vehicle collision analysis show that during the coll...
