Abstract
The paper introduced characteristics of various batteries used in trackless auxiliary haulage vehicles of coal mine including special type lead-acid battery of coal mine, flame-proof and start lead-acid battery, flame-proof and fixed lead-acid battery and new type lithium iron phosphate battery, and analyzed existed problems of the batteries in application and corresponding solutions. It pointed out development direction of batteries used in coal mine vehicles at present, namely large-scale trackless auxiliary haulage vehicles can also use special type lead-acid battery of coal mine, small-scale trackless auxiliary haulage vehicles would use new type lithium iron phosphate battery, and electric start and air start flame-proof diesel locomotives can use combined power supply of new type lithium iron phosphate battery and super capacitor.
