Effect of mass distribution on cornering dynamics of retrofitted EV

Vehicle dynamics data in different maneuvering condition is vital for developing more robust control approach. This study includes the calculation of center of gravity (CG) in case of retrofitting of a vehicle to maintain the mass redistribution of the vehicle as existing or to make it better by analyzing the effect on cornering dynamics of the vehicle. It comprises a comparative study on the optimal placement of EV drive train subsystems, such as batteries, power electronics and other accessories. Analysis has been conducted based on different modules of vehicle dynamics as example, lateral load transfer in different mass distribution layouts during cornering, effect of load transfers on tire grip; slip angle, polar moment of inertia etc. Different positioning of drive train components to obtain an optimum solution for vehicle handling and its stability in dynamic condition are proposed and evaluated.
