Using software GAMBIT as pre-processor and software FLUENT as calculator and post-processor

research was done on the effect of air-inlet and air-outlet patterns and battery positions on the electric vehicle aerodynamic performance. The results show as follows:up-outlet mode of wind with one hole has the best aerodynamic performance

and down-outlet mode of wind has the worst aerodynamic performance;with the distance between battery and power cabin increasing

the aerodynamic performance of electric vehicle is improved

and then deteriorated

and the distance of 230mm fits the best electric vehicle aerodynamic performance.
