Explosion-proof lithium battery box

Abstract

The invention discloses an explosion-proof battery box. The box comprises a box body, one side of the box body is provided with a sealed flip plate, the inner cavity of the box body is divided by a partition plate into a battery storage cavity and a detection treatment cavity; battery sets are arranged in the battery storage cavity, the positive electrodes and negative electrodes of each set of batteries are both provided with temperature strain sheets; and one side of the box body is provided with a wire inlet / outlet hole, which is communicated with the battery storage cavity. The provided explosion-proof lithium battery box has the advantages of simple structure, convenient assembly, and low production cost. A deformation detector is used to detect whether the battery sets expand or not to prevent explosion. When an abnormal situation is detected, the power supply can be cut off immediately, thus the deterioration of the situation is inhibited, the happening of accident is avoided; the temperature strain sheets can sense the temperature of batteries, when the temperature of batteries is higher than a preset temperature, the power supply is cut off, and the risk of explosion is effectively reduced therefore.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an explosion-proof lithium battery box. Background technique [0002] Today, with the rapid development of science and technology, electric vehicles are no longer a dream, and have been completely presented in front of the world. However, due to the high operating power of electric vehicles, the requirements for power and energy of power batteries are also extremely strict. . Due to the repeated charging and discharging of the battery during operation, a lot of heat will be generated, so in order to solve the heat dissipation problem of the battery, generally speaking, the battery box has a structure with multiple air ducts and multiple heat dissipation holes, but this design will bring many dark consequences. , when the battery is in an extreme working environment due to short circuit and other phenomena, it will easily come into contact with oxygen or other fl...

Problems solved by technology

Due to the repeated charging and discharging of the battery during operation, a lot of heat will be generated, so in order to solve the heat dissipation problem of the battery, generally speaking, the battery box has a structure with multiple air ducts and multiple heat dissipation holes, but this design will bring many dark consequences. , when the battery is in an extreme working environment due to short circuit and other phenomena, it will easily come into contact with oxygen or other flammable gases in the air, causing more serious consequences, and it is difficult to use fire extinguishing tools from the outside of the battery box due to combustion in the battery box Completely eliminate fire, therefore, we propose an explosion-proof lithium battery box
