Abstract

The invention discloses a flameproof lithium battery starting power source for coal mine. The flameproof lithium battery starting power source comprises a power supply circuit, a power management circuit, a control room circuit, a charge-discharge protection circuit, a charging circuit and a starting circuit. A lithium battery management unit is arranged in the power management circuit; an intermediate relay and a direct-current contactor are arranged in the charge-discharge protection circuit; the lithium battery management unit is capable of realizing detection and warning on the voltage, the temperature and the current of an individual battery; when the charging of a lithium battery pack is finished, the lithium battery management unit automatically controls the intermediate relay to switch off, and consequently, direct-current contact is stopped and the charging of the lithium battery pack is ended; in case of abnormal use of the lithium battery pack, the lithium battery management unit controls the intermediate relay to switch off, and consequently, the direct-current contact is stopped and the charging and discharging of the lithium battery pack are ended, and therefore, the lithium battery pack can be protected. In addition, the lithium battery management unit can be powered by a charger by use of a first diode and a second diode when the lithium battery pack is completely drained.

Description

technical field [0001] The invention relates to a coal mine explosion-proof lithium battery starting power supply. Background technique [0002] At present, the starting power supply of diesel locomotives in coal mines is mostly flameproof starting lead-acid batteries, which have the disadvantages of small capacity, large self-discharge, short life and serious environmental pollution. Lithium-ion batteries have remarkable characteristics such as high specific power and specific energy, green and pollution-free, and long service life. They are the best substitute products for lead-acid batteries and the development direction of new secondary batteries. Anbiao National Center issued five documents including "Safety Technical Requirements for Mining Lithium-ion Batteries (Trial)" and "Safety Technical Requirements for Mining Explosion-proof (and Intrinsically Safe) Lithium-ion Batteries (Trial)", which marks the lithium-ion The application of ion storage battery in the undergr...
