Multi-cavity independent safety test box, temperature control box and cold plate box

Abstract

The invention discloses a multi-cavity independent safety test box. The multi-cavity independent safety test box comprises a box body; a plurality of independent anti-explosion cavities are formed inthe box body; and each anti-explosion cavity is respectively provided with an anti-explosion door, and a battery wire connection assembly is fixed on the inner side wall of the anti-explosion door. The invention further discloses a multi-cavity independent safety temperature control box and cold plate box. An independent temperature regulation device is arranged in each anti-explosion cavity. By adopting the technical scheme, compared to the prior art, a plurality of independent small anti-explosion cavities which are isolated from each other and independent of each other are formed, and the battery wire connection assemblies and the anti-explosion doors are integrated, so that a chain reaction and expansion of damage in emergency can be effectively limited, and independent temperature control on each anti-explosion cavity can be implemented; and the modular structure also can effectively improve wire connection efficiency and avoid a wire connection error.

Description

technical field [0001] The invention relates to a multi-chamber independent safety test box, a multi-chamber independent safety temperature control box and a multi-chamber independent cold plate box, belonging to the technical field of battery detection. Background technique [0002] Batteries are used more and more frequently in people's daily life. Generally, batteries need to do some tests before use to determine whether they are qualified, including voltage internal resistance test, capacity test, overcharge, overdischarge, short circuit test and other test content. During the test, the battery may explode, burn, and even endanger the safety of the staff. Therefore, some protective treatment will be done during the battery test, such as the battery explosion-proof test box. The test box in the prior art is generally a large box, and all batteries are put into one box. If an abnormality (explosion or combustion) occurs in an individual battery during the charge and discha...

AI Technical Summary

Problems solved by technology

The test box in the prior art is generally a large box, and all batteries are put into one box. If an abnormality (explosion or combustion) occurs in an individual battery during the charge and discharge test, it will cause damage to adjacent batteries and experimental related equipment. Unnecessary damage; in addition, the existing test box can only control the temperature inside the box as a whole, and cannot meet the specific ambient temperature required by different types of battery tests at the same time, or different test temperature conditions for the same type of battery, that is, for different tests Batteries with ambient temperature requirements cannot be tested at the same time, which greatly reduces work efficiency

At the same time, the wiring in the existing test box is complicated. Each battery tray in the box needs to be connected with a bunch of wires. All the wires are inserted into the box through the wiring channel on the side wall of the box, and then connected to the battery one by one. It is very cumbersome and prone to misconnection
