As the battery temperature shows a high distribution in the middle and low distribution around during the operation of electric vehicles, it affects the battery service life. To this end, a steady-state heat conduction structure design method based on Floating Projection Topology Optimization (FPTO) is proposed using the geometric mean temperature as the objective function, and the maximum temperature and temperature difference of the power battery pack under single and multiple operating conditions are comparatively analyzed by means of an arithmetic example, which demonstrates that the obtained topological configuration can effectively reduce the maximum temperature and temperature difference in the heat dissipation process during the multiple operating conditions, so as to make the temperature distribution uniform. Finally, the method is applied to the power battery pack support structure, and the results show that the method effectively reduces the temperature without increasing the volume of the battery pack structure, optimizes the distribution of materials, and realizes lightweight of the overall structure of the battery pack.
