Modelling and scaling procedure of a vehicle electric drive system
This report describes the modelling and scaling of the drive systems in a small and a large BEV. Typical drive system components (electric motor, inverter, battery and transmission) are chosen, and modeled. Initially all components are sized in order for the two BEVs to fulfill a set of specified vehicle requirements. Then the electric motor is scaled by axial length in order to give a linearly varying output power and torque. A scalable inverter model is suggested that scales with the current rating, for a fixed voltage rating.
