摘要：
To maintain the performance of the power battery and prolong its service life, the temperature and temperature difference during the operation of the battery module should be maintained within an appropriate range. Thus, a new type of honeycomb liquid-cooled power battery module is proposed. The structure has an inlet/outlet guide plate inside and the battery is honeycomb-like distribution. The cooling liquid contacts with the battery indirectly at 360°, which greatly strengthens the heat transfer effect. On the basis of the numerical simulation and experimental validation of the thermal characteristics of single battery, a new model of honeycomb liquid-cooled battery module was established by computational fluid dynamics(CFD) platform, the thermal behavior of the battery module was studied, and the effects of the coolant flow rate, the coolant temperature of battery on the heat dissipation performance of the battery module were studied. The results show that: (1) Increasing the flow rate of coolant can significantly reduce the maximum temperature of the battery module and improve the temperature uniformity, when the flow rate of coolant increases to 1.5 L/min, the maximum temperature and the maximum temperature difference of the battery module tend to be stable; (2) Decreasing the temperature of coolant can significantly reduce the highest temperature of the battery module, but to a certain extent, the temperature uniformity in the battery module is deteriorated; (3) The coolant flow rate and the coolant temperature have significant influence on the heating characteristics of the battery module. Therefore, liquid cooling is necessary. © All Right Reserved.
