Explosion-proof battery

Abstract

The invention provides an explosion-proof battery. The explosion-proof battery comprises: a box body and an explosion-proof box body; a temperature adjusting module connected with the box body and used for adjusting the actual temperature of the box body; a battery module, wherein the first area of the battery module comprises all the electrodes, and the second area of the battery module comprisesall the pressure release valves; a first encapsulation layer which covers the first area, wherein the first opening of the first encapsulation layer corresponds to the pressure release valve to makethe pressure release valve exhaust air through the first opening; and a second encapsulation layer which covers the second area to make the pressure release valve break through the second encapsulation layer during pressure release. According to the invention, the implementation cost and weight of a battery explosion-proof mechanism can be effectively reduced, a temperature control protection mechanism for the box body is realized, the explosion risk possibly caused by over-high temperature in the box body can be effectively avoided, and other exposed conductors except the encapsulated batterymodule are not electrified when an explosive environment appears, so that the contact between an ignition source and explosive gas is blocked in time, and the economy and the explosion-proof controleffect of an explosion-proof mechanism are effectively improved.

Description

technical field [0001] The invention relates to the technical field of battery safety applications, in particular to an explosion-proof battery. Background technique [0002] At present, the large-capacity explosion-proof batteries used in underground coal mines are mainly special-type or increased-safety lead-acid battery power sources. Explosion-proof standards have many restrictions on the use of lead-acid batteries, and there has been no particularly good solution for underground large-capacity batteries for power supply. In recent years, various types of downhole robots, intelligent dangerous mixture monitoring and monitoring systems, and pure electric auxiliary transportation equipment based on new technologies such as 5G and the Internet of Things have gradually emerged. These equipments have an increasing demand for battery capacity. The current situation has become a technical bottleneck restricting the development and application of underground robotic equipment. ...
