[0003] In order to extend the cruising range of electric vehicles, higher requirements are put forward for the power batteries of electric vehicles. Since the space of electric vehicles is limited, in order to improve the cruising range of electric vehicles, it is necessary to place as many batteries as possible in the limited space. , but the power battery emits a lot of heat when it is working. If the heat cannot be dissipated in time, it will seriously affect the stability of the battery and shorten the service life of the battery. In addition, because the car is often in a bumpy state during driving, the existing The connections of the single cells in the power battery are often unstable, posing serious safety hazards

The invention relates to a power battery module for an electric vehicle, comprising a battery box body in which several single batteries are placed, a fixing plate is arranged in the battery box body, and a heat dissipation column is installed on the fixing plate. A heat dissipation plate is provided on the top of the body, and the single battery, the heat dissipation column and the heat dissipation plate are sequentially contacted and connected together. The structure design of the electric vehicle power battery module of the present invention is reasonable. By setting the fixing plate, the heat dissipation column and the heat dissipation plate, the single battery, the heat dissipation column and the heat dissipation plate are sequentially contacted and connected together, and the heat emitted by the single battery can be quickly dissipated. In the external environment, the internal temperature of the power battery module and the operating temperature of the single battery are greatly reduced to ensure the normal operation of the single battery and the entire power battery module, prolonging the service life of the power battery; also greatly improving the overall connection stability of the power battery , to ensure the stability and safety of the power battery.
Description
technical field [0001] The invention belongs to the technical field of batteries, and specifically refers to an improvement of an electric vehicle power battery module. Background technique [0002] With the serious global pollution, the realization of emission reduction has become a global concern, and the use of new energy sources to replace petroleum has also attracted attention. Many companies are vigorously developing electric vehicle power batteries and using power batteries as energy sources. [0003] In order to extend the cruising range of electric vehicles, higher requirements are put forward for the power batteries of electric vehicles. Since the space of electric vehicles is limited, in order to improve the cruising range of electric vehicles, it is necessary to place as many batteries as possible in the limited space. , but the power battery emits a lot of heat when it is working. If the heat cannot be dissipated in time, it will seriously affect the stability o...
