Design of Mine Vehicle-type Lithium Ion Power Management System

In view of large-capacity Lithium ion battery being widely applied in coal mine，a power management system with mine vehicle lithium ion battery for mine electric control system was designed.Based on CAN bus，the distributed control management and protection for each single power is realized.According to the interim provisions on mine safety standards for the lithium-ion batteries and the facts that lithium-ion battery itself needs the protections of over-current，overload，extreme temperature and overcharge and over discharge to ensure the safe utilization of the lithium-ion battery power in coal mine environment.It realizes the health charging and fast charging of lithium ion battery by intelligent or manual control to improve the practicability of vehicle power.Meanwhile，the monomer of low voltage battery is charged by the way of active equalization，which made the whole lithium ion battery consistent in performance.The tests and the industrial application showed that this system can better guarantee the effective capacity of lithium-ion power and effectively extend the service life of lithium-ion power supply.
