The invention relates to a travel-extending auxiliary power battery device for a pull type electric vehicle. The method is used for increasing the cruising ability of the electric automobile. The system is composed of an auxiliary power battery, a trailer, a tow bar, a cable, a plug, a mileage counting meter and a wireless internet communication module. The auxiliary power battery is placed on the trailer, and the trailer is connected to a trailer frame of the electric automobile through a tow bar and runs along with the electric automobile. The auxiliary power battery is connected to an auxiliary power socket of the electric automobile through a cable and a plug, and the change-over switch is used for switching power supply of the vehicle-mounted battery and power supply of the auxiliary power battery to convert an electric energy source of the electric automobile; a mileage counting meter is mounted on the trailer and is used for charging management; a wireless internet communication module is installed on the trailer and used for intelligent renting operation management. The capacity of a vehicle-mounted power battery is not increased, the cruising ability of the electric vehicle is improved, and the long-distance driving requirement of the electric vehicle is met. And through intelligent battery operation management, the requirements of the society on the number of electric vehicle batteries and the number of charging piles are reduced.
