Optimization of Liquid Cooling Heat Dissipation for Electric Vehicle Power Battery Packs
The charging and discharging process of electric vehicle power batteries generates a large amount of heat,and the devel-opment of an efficient heat dissipation design is conducive to improving the efficiency and safety of the battery packs.A combination of cold plate and battery packs was used for the liquid cooling heat dissipation design of the battery packs.The critical maximum tempera-ture was set to 50 ℃ here and the results showed that the average battery temperature was lowest and the temperature uniformity was better when the cold plate and battery packs were arranged in a side-to-side lateral direction.The minimum required mass flow rate was 0.05 kg/s for the inter-phase lateral model,while the inter-phase upward model had the lowest pressure drop.Therefore,a structure with an interphase arrangement of power battery and cold plates can be preferred for the thermal design of the battery packs.
