The optimization of the battery pack structure mainly focused on reducing the battery maximum temperature and improving the temperature uniformity by optimizing the arrangement of the battery pack and the battery spacing.
To simplify the model, the specific geometry of the battery package is simplified. The diagram of the battery pack under air cooling is shown as Fig. 2. The left side of the battery pack corresponds to the air inlet, while the right side is the air outlet.
Thus, the maximum temperature is mainly affected by the temperature difference and the temperature difference can be used as an indicator to evaluate the heat dissipation performance of the battery pack. Fig. 12. Maximum temperature of the battery for different spacing combinations. Fig. 13.
Studied the battery temperature within the battery pack using ANSYS Fluent. Studied the influence of battery spacings on cooling performance of battery pack. The optimization variable number was reduced by grouping the batteries. The Bayesian neural network model was established with CFD simulation results.
Each cell has a current of 5.75Ah. The current of the pack is 345Ah and the pack voltage is 44.4Volts. The pack provides power to a motor which in turn drives the wheels of an EV. I wanted to design the cooling system for the battery pack, so wanted to know the heat generated by the battery pack.
This combination led to a minimum temperature difference of 5.8666 (K) and a maximum temperature in the battery pack of 300.4115 (K). Fig. 21. Temperature difference of the battery pack under a part of spacing combinations. Some spacing combinations are shown in Table 3, under which the corresponding temperature difference is very small.
