Abstract: In this paper, the influence of explosion-proof power battery on the drving range of pure electric explosion-proof vehicle is analyzed. The methods and results which can maximally improve the driving range of pure electric explosion-proof vehicle under the condition of lower specific energy of explosion-proof battery are proposed. And based on a certain type of pure electric explosion-proof vehicle, the combination property test by vehicle test stand and the VehSpy3 upper system are completed. The results show that the method can effective promote the range of pure electric explosion-proof vehicle.
