This study conducts an experimental and numerical simulation to discover the influence of the number of cooling channels on temperature rises and temperature distribution. This study limited the battery module to three batteries connected in series and underwent a discharge and charge process at C-rating of 3C and 2C. The experiment is conducted to discover the temperature rises for each pipe configuration and to validate the simulation process. The experiment setup was successfully developed to analyze the influence of the number of pipes on the rise in battery temperature. As the number of pipes increases, the battery's temperature decreases. It has also been discovered that as the number of pipes increases, the temperature difference between the configurations will be less significant, as in 3 and 4 pipe configurations. The simulation of the battery's pipe cooling channel was successfully conducted and validated, with the experiment results being within a 15% error range. According to the simulation results, the temperature distribution of the battery will become more uniform as the number of pipes increases. In this case, four pipe configurations are optimal for the 3C discharge/charge process, and three are optimal for the 2C discharge/charge process. However, determining the optimal pipe configuration in other battery systems will require further analysis that depends on heat transfer parameters, such as inlet temperature, contact area, flow rate, pipe material, and pipe thickness.
