AB - To ensure that a lithium battery can operate in the appropriate temperature  range, the 18650-type lithium battery (cylindrical battery with diameter of  18 mm and height of 65 mm) was selected as the research object, and the  thermal model of single battery was established. Compared with reference  values, the data correlate well and the accuracy of the model is validated.  The liquid-cooling model of a honeycomb lithium battery module was  established based on a thermal model of a single battery. By using numerical  simulation, the coolant flow rate, coolant temperature and central angle of  coolant channel are set as variables to analyze the heat transfer  characteristics of the battery module at different ambient temperature. The  results show that (1) Increasing the flow rate and the central angle of the  coolant channel can improve the temperature homogeneity. Compared with the  flow rate, the central angle has a greater effect on the heat transfer  characteristics. (2) The coolant temperature has a significant effect on the  temperature distribution of the battery module. However, the temperature  homogeneity is deteriorated.
