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. The optimization of the parameters includes the design of the liquid cooling plate to better adapt to the shape and size of the battery
In addition, the type of coolant due to the difference in thermal conductivity also affects the cooling effect of the cooling and heat dissipation system of the lithium battery pack.
With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
In severe cases, the lithium-ion battery can experience thermal runaway , resulting in issues such as spontaneous combustion and explosion . Due to the characteristics of lithium-ion batteries, the allowable working temperature should be controlled within 20~40°C, with a maximum temperature difference not exceeding 5°C .
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.
For three types of liquid cooling systems with different structures, the battery’s heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
Analysis of the effect of ambient temperature The cooling plates only contact with the bottom of the NCM battery modules and the left and right sides of the LFP battery modules, the other surfaces of the battery module, for heat dissipation, rely on convection heat exchange with air.
