Disclosed is a battery pack power supply system for reducing burning probability of battery packs of electric vehicles. Two battery pack boxes of the system can be automatically replaced, power source surge protectors of the battery pack boxes are connected with the battery pack boxes and capable of discharging leak current on the battery pack boxes, and power cords of the power source surge protectors are serially or parallelly connected with an input current power cord and an output current power cord in a filtering manner, so as to prevent burning of the battery packs caused by high-current attack during short circuit and charging. When the first battery pack's temperature still rises after up to 150 degrees Centigrade, a switch of the power source can be pressed to separate a front bracket of an electric jack from the battery pack boxes, and the first battery pack box is abandoned, similarly when the second battery box' temperature is out of control, temperature of the two battery packs is out of control and the two battery pack boxes can be abandoned and the electric vehicles can be pulled over nearby by means of freewheeling.
