But the higher temperature also accelerates the harmful reaction rate, the polar plate is easy to damage, overcharge is easy to occur, the service life of the battery is seriously influenced, and the structure of the battery is permanently damaged. Especially in the battery use, when influenced by joule heat, reaction heat, polarized heat and the like, a large amount of heat gathers, the temperature rises sharply, the service life and the circulation efficiency of the battery are influenced, and even explosion is caused seriously, so that certain temperature limitation is needed, and when the most suitable working environment temperature of the lithium ion battery is 0-30 ℃ and a large amount of power lithium ion batteries are combined into a battery pack, a large amount of heat is easy to generate, and in an electric vehicle with poor heat dissipation, the temperature of the actual working environment of the battery is easy to be far higher than the normal working temperature, and potential safety hazards can be brought. Therefore, it is necessary to take heat dissipation measures for the electric vehicle power lithium ion battery. At present, a centrifugal battery fan type heat fan, namely air cooling is mainly adopted as a heat radiating device of the power battery pack; or the outer rotor type three-phase permanent magnet synchronous motor is used as a driving motor, the heat dissipation air port adopts a fixed pane to realize heat dissipation of the storage battery, and the air outlet cannot be sealed, so that the safety and the service life of the power battery pack are affected, and the use requirement of the electric automobile which is vigorously developed at present on heat dissipation of the power battery cannot be met.
