The invention discloses an electric vehicle battery pack with a spontaneous combustion prevention function, and relates to the technical field of new energy batteries. The battery pack with the spontaneous combustion prevention function for the electric vehicle comprises a base and a heat dissipation shell fixedly connected to the base, the surface of the base is connected with a pipe network, and an inlet of the pipe network is fixedly connected with an air inlet pipe through a first electric three-way valve; a plurality of battery packs are arranged in the heat dissipation shell, each battery pack comprises four storage batteries, each storage battery is limited through a fixing piece, and the fixing piece is of a double-layer structure and is fixedly connected with an outlet of a pipe network. According to the storage battery heat dissipation device, external cold air is introduced into the pipe network, is fed into the fixing piece with the double-layer structure and is finally discharged through the sealing cover with the hollow structure, so that heat dissipation of the storage battery can be realized, and different schemes can be adopted for heat dissipation of the storage battery according to measurement of the temperature sensor, so that targeted treatment is performed, and the storage battery heat dissipation efficiency is improved. And the operation of the battery pack is ensured.
