Abstract: Controlling the temperature of the power battery pack has always been a technical problem in the field of new energy buses.Taking the power pack of an electric bus as the research object,the authors establish a three-dimensional physical model of the power battery pack,divide the finite element meshes of the power battery pack by ANSYS Workbench software,and carry out the heat dissipation analysis by Fluent module to research the influence of discharge rate,coolant flow rate and ambient air temperature on the temperature of power battery pack.
Key words: electric bus; power battery pack; heat dissipation; discharge rate; coolant flow rate; ambient air temperature
