Outline
To solve the problem of high temperature rise and poor temperature uniformity of energy storage battery module under high-rate operation, considering the heat generation of batteries and aluminum bars, an electric-thermal-fluid coupling simulation model for battery module was established, and the influence of cold plate arrangement scheme and flow rate on the temperature characteristics of the battery module was analyzed. The results indicate that the scheme of arranging double large surface or side cold plates can control the maximum temperature rise within 11.0 K, which is better than the scheme of arranging single large surface cold plates. The scheme of arranging side cold plates is superior to the scheme of arranging large surface cold plates in controlling the temperature rise range. Increasing the flow rate can effectively reduce the maximum temperature rise and temperature rise range of the module when the flow rate is within 3.0 L/min. Adding bottom cold plates in the scheme of arranging large or side cold plates can improve the temperature characteristics of the module when the flow rate is within 2.0 L/min. The comparison between experimental and simulation results shows that the maximum temperature rise error is within 0.9 K, which verifies the accuracy of the coupled simulation model.
