Embodiment

[0021] Example: such as figure 1 and figure 2 As shown, a battery pack safety test box includes a cylindrical airtight box 1 , and the inside of the airtight box 1 is divided into a battery pack safety test chamber 2 and an air chamber 3 by a partition 4 . The battery pack safety test chamber 2 is located below the air chamber 3, and the partition plate 4 can move freely up and down. Among them, the airtight box 1 and the partition 4 are made of special steel plates with a thickness of 1mm~10mm, which can effectively prevent the shock wave stress generated when the battery pack may explode. .

[0022] The airtight box 1 is provided with a detachable top cover 12 above the air chamber 3 , and two pressure relief valves 13 are provided on the top cover 12 .

[0023] The air chamber 3 is provided with a safety airbag 16 , and the opening of the safety airbag 16 communicates with the pressure relief valve 13 .

[0024] The volume of the air chamber 3 is more than five times t...

Abstract

The invention discloses a safety test box of a battery pack, comprising a closed box body. The interior of the closed box body is divided into a safety test chamber of the battery pack and an air chamber by a baffle. The invention can efficiently weaken the impact generated by explosion and better protect equipment safety and personal safety and has high safety performance.

Description

technical field [0001] The invention relates to a battery pack safety test box. Background technique [0002] Power batteries are widely used in various fields, especially in recent years with the development of the electric vehicle industry, more and more attention has been paid to power batteries, and its safety performance has always been the focus of attention of various manufacturers and users. Due to the large capacity of power batteries , which is a high-density energy storage device, once an accident occurs, it will affect the use of the equipment at least, and may cause explosion and combustion at the worst. There are detailed and strict regulations, and the safety performance of each battery varies greatly depending on the production process, structural design and use environment. A comprehensive safety performance test is required, and high-risk experimental phenomena may occur during the test process, which is harmful to the safety of operators. There are consid...
