Problems solved by technology

When a single battery has an extreme failure such as thermal runaway, a large amount of gas will be generated and released. There is a risk that the released gas will accumulate in the power box and cause an explosive accident due to excessive pressure in the box, which will bring great harm to the safe operation of battery power. However, there is no good solution in the industry at present, and it needs to be solved urgently

Abstract

The invention provides an explosion-proof battery power supply, which comprises a box body, an explosion-proof box body, a battery module, a first encapsulation layer and agas treatment device; a first area of the battery module in the box body comprises all the electrodes, and a second area comprises all the pressure release valves; the first encapsulation layer covers the first area, and first openings of the first encapsulation layer correspond to the pressure release valves, so that the pressure release valves can exhaust air through the first openings; and the gas treatment device is arranged in the box body and is used for treating gas released in the thermal runaway process of the battery module. A gas treatment mechanism is realized by adopting the gas treatment device, so that theinfluence of gas released by thermal runaway of the battery on the peripheral environment of the box body is effectively reduced, the overall application safety of the explosion-proof battery power supply is improved, the realization cost and weight of the battery explosion-proof mechanism are effectively reduced, and the explosion-proof battery power supply is ensured to be not damaged except the encapsulated battery module when an explosive environment occurs. other exposed conductors except the encapsulated battery module are not electrified when an explosive environment occurs, so that the contact between an ignition source and explosive gas is blocked in time, and the economy and the explosion-proof control effect of an explosion-proof mechanism are effectively improved.

Description

technical field [0001] The present application relates to the technical field of battery safety applications, in particular to an explosion-proof battery power supply. Background technique [0002] At present, the large-capacity explosion-proof battery power supply used in coal mines is usually composed of a large number of single batteries, and the power box can accommodate and protect the battery pack. When a single battery has an extreme failure such as thermal runaway, a large amount of gas will be generated and released. There is a risk that the released gas will accumulate in the power box and cause an explosive accident due to excessive pressure in the box, which will bring great harm to the safe operation of battery power. However, there is no good solution in the industry at present, and it needs to be solved urgently. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. ...
