Abstract: Thermal management is a critical issue in the design of high-rate energy storage battery modules. This paper investigates the liquid cooling scheme for high-rate modules through 1C charge-discharge experiments. The results indicate that the module fails to reach thermal equilibrium during the charge-discharge process, with the temperature continuously rising. Among the tested schemes, the scheme with large-surface cold plates achieves the best effect in controlling the maximum temperature rise, followed by the scheme with side and bottom cold plates, and the scheme with only side cold plates performs the worst. The scheme with bottom cold plates achieves the best effect in controlling the temperature rise difference. Increasing the flow rate in each scheme can reduce the maximum temperature rise, and the large-surface scheme can also reduce the temperature rise difference. The addition of bottom cold plates to either large-surface or side cold plates schemes reduces the temperature rise difference. Furthermore, it also decreases the maximum temperature rise in the case of side cold plates.
