During the charging and discharging process, lithium-ion batteries generate a large amount of heat. If the temperature is too high, it may cause battery failure or safety problems. As one of the most important technologies of battery cooling system, lithiumion battery cold plate cooling technology is significant to ensure battery safety. Firstly, this paper systematically analyzes the relevant methods of cold plate liquid cooling design, and compares the advantages and disadvantages of different methods. The mainstream cooling method for lithium-ion battery thermal management systems is currently liquid cooling, which boasts higher heat dissipation efficiency. With the increase in battery energy density, the future development trend of electric vehicle thermal management systems may move towards hybrid cooling, systematic design, and intelligent management.
