摘要：
In this paper, a reliable cell heat generation model is established by using Bernardi heat generation rate equation through simulation and experimental verification, and the simulation and experimental error is less than 2%. Based on this, the heat generation model of the module under the influence of the bus-bar heat generation is established. For improved design of the original cooling system for insufficient cooling effect on the top area of the module and the bus bar, for the cooling plate arrangement, it is proposed to install the cooling plate on the side of the module, and then to select the appropriate cooling plate thickness, cooling fluid volume concentration and the coolant inlet velocity through simulation analysis. In the final design, the average temperature rise of the bus-bar of the cooling system module, cell and top surface of the module is reduced by 15.56%, 11.48% and 20.34% respectively, and the temperature distribution on the cell of the module is more uniform. © 2022, Society of Automotive Engineers of China.
