Abstract: |
This work presents the liquid cooling system for powered battery applied on electric vehicle (EV). The objective is to design a liquid cooling system for the battery pack. The work contains a brief introduction of the current development of the electric vehicles, highlighting the importance of the thermal management system of the battery system, which motivates the project. Followed by a deep marketing research, which contains the classification of batteries, cooling methods and heating methods. The bibliographical review points out the liquid cooling system is the best way for the current market considering the cost, performance and the reliability. Then design the CAD models, one is tab cooling, the other one is the side surface cooling. The simplified FEM models are constructed using the commercial code Hyper mesh in order to obtain the temperature distribution of the batteries. This reduced model is going to be introduced in the Acusolve, where the temperature variation can be obtained by changing the parameters, for example the temperature of the coolant inflow, the flow rate of the coolant and the power density of the batteries. For reaching the final conclusions, these models are applied to the real driving cycle, where the discharging rate are variable. The results are conclusive about the importance of the temperature, the flow rate of the coolant and the dimension of the heat exchanging surface inclusion in the thermal management system of the battery pack.   |
