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 connected with the box body; a battery module arranged in the box body, wherein a first area of the battery module comprises all electrodes in the battery module, and a second area of the battery module comprises all pressure release valves in the battery module; a first encapsulation layer covering the first area, wherein a first opening of the first encapsulation layer corresponds to the pressure release valve to make the pressure release valve exhaust air through the first opening; a second encapsulation layer which at least covers the second area to make the second encapsulation layer broken through when the pressure release valve is opened; a power supply control module arranged in the explosion-proof box body; and a first lead device arranged between the explosion-proof box body and the box body. According to the invention, the implementation cost and weight of a battery explosion-proof mechanism can be effectively reduced, and it is ensured that when an explosive environment occurs, except for the encapsulated battery module, other exposed conductors are not electrified, so that contact between an ignition source and explosive gas is blocked in time, and the economical efficiency and the explosion-proof control effect achieved by 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. 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 e...
