Numerical investigations on the effect of an underbody battery on solar vehicle aerodynamics

The placement of the battery box can have a massive impact on the aerodynamics of an electric vehicle. Although favourable from the viewpoint of vehicle dynamics, an underbody battery box may impair the vehicle aerodynamics. This study aims to quantify the effect of an underbody battery box on the drag force acting on an electric vehicle. Four different variants of the vehicle (original variant, lifted suspension, lifted suspension with an underbody battery box) are investigated by means of computational fluid dynamics. The underbody battery box was found to induce flow separation, resulting in a massive increase in drag force. As a solution, a battery box fairing was designed and tested. The fairing significantly reduced the increase in drag. The results of this study could contribute to the design of more stable and aerodynamically efficient electric vehicles.
