Explosive-proof and intrinsic safe type lithium ion battery power for mine

Abstract

The invention discloses an explosive-proof and intrinsic safe type lithium ion battery power for a mine. The explosive-proof and intrinsic type lithium ion battery power for the mine comprises an explosive-proof shell, lithium ion battery groups, battery management system auxiliary controlling units, battery management system main controlling units and a battery group protecting unit. The explosive-proof shell comprises an explosive-proof battery cavity shell, a battery management cavity shell and a wiring cavity shell. The lithium ion battery groups, the battery management system auxiliary controlling units and electrical elements are placed in the explosive-proof battery cavity shell, the battery management cavity shell and the wiring cavity shell respectively. The lithium ion battery groups, the battery management system auxiliary controlling units and electrical elements are connected through a wire and explosive-proof through-wall sockets. Battery information is collected by the battery management system auxiliary controlling units, and the battery management system auxiliary controlling units are controlled by the battery management system main controlling units through a CAN bus. The explosive-proof and intrinsic type lithium ion battery power for the mine has the advantages of being good in explosive-proof performance, light in design, good in safety performance, and long in service life.

Description

technical field [0001] The invention relates to a power supply, in particular to a mine flameproof and intrinsically safe lithium-ion storage battery power supply. Background technique [0002] At present, lead-acid batteries are generally used as power sources for mining batteries. Lead-acid battery technology currently has the following problems in use: ① long charging time; ② short service life, lead-acid batteries can theoretically use 500 cycles, but in actual use generally only reach 400 cycles; ③ quality The specific energy and volume specific energy are low; ④Environmental pollution is large, and the raw materials used in lead-acid batteries are unenvironmentally friendly lead and acid; ⑤The safety is low. There is a big safety hazard; 6. It is harmful to health. The initial charging and daily charging are very harmful to the human body. Due to the strong volatility and toxicity of sulfuric acid, the pungent odor produced will pose a threat to the physical and menta...
