Outline
Based on the experimental validation of a single-cell heat generation model, this paper proposes a thermal management battery module for a liquid-cooled system integrated with phase change material (PCM). The effects of the number of cooling channels, flow rate, cold channel arrangement and cooling plate thickness on the maximum temperature and temperature uniformity of the battery pack are quantitatively studied by using numerical simulation methods. The results show that at the discharge rate of 4 C and 35 ℃, altering the coolant flow rate in three cooling channels can greatly affect the maximum temperature and the maximum temperature difference of the battery module. Furthermore, once the coolant flow rate exceeds 0.2 m/s, the heat dissipation performance of the battery module does not show significant improvement. With the same number of cooling channels, the best temperature uniformity between battery packs and along the axial direction is achieved with a staggered distribution of coolant inlets and outlets. When the cooling flow rate and the number of cooling channels remain constant, increasing the thickness of the cooling plate can reduce both the maximum and minimum temperatures of the battery module. However, once the thickness reaches 8 mm with three cooling channels, further changes in temperature become negligible.
