Abstract: Aiming at resolving air pollution caused by explosion proof diesel engine vehicle, the application of explosion proof electric vehicle grew apparently. Related to core indications, such as driving range and charging time, power battery technology is a key technology of electric vehicle. According to different suitable vehicle types, colliery power battery was divided into special type explosion proof lend-acid battery and flameproof lithium-ion battery. Based on actual application cases, the feature and their suitable situation were analyzed separately. It was concluded that special type explosion proof lend-acid battery would be the major energy system solution of heavy operating vehicles for a long time. Because of extra weight caused by flameproof box, the advantage in energy density of lithium-ion battery could not reflected adequately. Energy density extension of flameproof lithium-ion battery and reliability promotion of battery management system would be the development direction of flameproof lithium-ion battery.
