Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.
Researchers claimed that if contact is increased, enough time can be provided for the heat to dissipate. The thermal management of the battery encompasses three cooling methods: air cooling (the simplest), liquid cooling, and phase change material (PCM). R. D.
To verify the effectiveness of the cooling function of the liquid cooled heat dissipation structure designed for vehicle energy storage batteries, it was applied to battery modules to analyze their heat dissipation efficiency.
Under the fast growth of electric and hybrid vehicles, the heat dissipation problem of in vehicle energy storage batteries becomes more prominent. The optimization of the liquid cooling heat dissipation structure of the vehicle mounted energy storage battery based on NSGA-II was studied to reduce the temperature.
With an increase in cooling flow rate and a decrease in temperature, the heat exchange between the lithium-ion battery pack and the coolant gradually tends to balance. No datasets were generated or analysed during the current study. Kim J, Oh J, Lee H (2019) Review on battery thermal management system for electric vehicles.
The objective function and constraint conditions in the optimization process were defined to maximize the heat dissipation performance of the battery by establishing the heat transfer and hydrodynamic model of the electrolyzer.
