To cope with the problem of global warming and improve the performance of electric vehicles, the power source of electric vehicles is researched. First, the CFD simulation analysis method is utilized to analyze the heat dissipation effect under the changes of the air intake speed, the number of fins, and the thickness of the fins between lithium batteries. Then, the orthogonal experiment is utilized to select the optimal solution between the lithium batteries. The simulation results show that the heat dissipation effect is optimal under the conditions that the inlet air speed is 8 m/s, the number of fins is seven, and the thickness of fins is 2.5 mm. Then, the orthogonal experiment determines the optimal heat dissipation scheme of the lithium battery pack the air inlet speed is 8 m/s, the number of fins is six, and the thickness of the fins is 2 mm. This optimal scheme can effectively improve the heat dissipation performance of lithium batteries, enhance the performance of electric vehicles, and reduce CO2 emissions.
