Problems solved by technology

In the traditional electric vehicle battery pack, the positive electrode of the battery is very easy to catch fire. When one of the single cells catches fire, if there are no fire prevention measures, it is easy to cause the surrounding single cells to catch fire, and the fire spreads and even causes the explosion of the entire battery pack. The traditional The battery packs used in electric vehicles have poor fire performance, and there are potential safety hazards

Embodiment Construction

[0013] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0014] Such as figure 1 and figure 2 An explosion-proof battery pack is shown, a kind of explosion-proof battery pack, including a battery pack 1 formed by multiple rows and rows of single cells 2, the battery pack 1 is covered with a fireproof mat 3, and the fireproof The pad 3 is provided with a fire discharge gap 4 and a total fire discharge hole 5. The fire discharge gap 4 is arranged in multiple rows and rows, and the fire discharge gap 4 is located directly above the positive pole of the single battery 2. The total fire discharge hole 5 is located at one side end of every row of fire-discharging gap 4.

[0015] The fire discharge gap 4 includes a soft column 41, a tip ...

Abstract

The invention discloses an anti-explosion battery pack which comprises a battery pack body formed by a plurality of rows and a plurality of lines of cells, wherein a fireproof mat covers the top of the battery pack body, and is provided with a plurality of rows and a plurality of lines of fire exhausting gaps and a total fire exhausting hole, the fire exhausting gaps are positioned just above anodes of the cells, and the total fire exhausting hole is formed in the end part of one side of each row of the fire exhausting gaps. The anti-explosion battery pack is simple in structure, reasonable in design, and convenient to operate; the fireproof and anti-explosion performances are improved; after the fireproof mat is arranged, fire exhausted from the anodes of the cells are dredged, so that the fire is effectively prevented from spreading to the cells around, and the explosion probability of batteries is reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an explosion-proof battery pack widely used in the electric vehicle industry. Background technique [0002] With the development of society and the improvement of people's living standards, cars are becoming more and more popular. But at the same time, the problems of global environmental pollution and oil shortage are also more prominent. People began to consider using batteries as the power source of cars, and this electric car using new green energy came into being. The design of the battery pack needs to consider many factors, not only to ensure that the battery performance meets the requirements of the car, but also to ensure that the battery has sufficient safety and reliability. It is also necessary to consider the cooperation between the battery pack and the car to reduce the quality and volume of the vehicle. These are closely related to the structure of the battery ...
