Dynamic Modelling and Performance Assessment of a Single Battery Electric Vehicle Powertrain System Employing an Induction Motor

A dynamic model of a single battery electric vehicle (BEV) powertrain employing an induction motor (IM) is developed to capture and control the steady-state and transient behaviour of the overall system. The novelty of the model is that all the electric vehicle components including the car aerodynamics, drive cycle, power electronics drive, and battery are integrated, along with their dynamics to model the response of the system, while maintaining the simplicity and feasibility of simulation. The presented control mechanism ensures the proper switching operation modes of BEV; the accelerating, cruising, and regenerative braking. The power management controller is responding efficiently to the demanded traction power while avoiding the battery blackout or over-discharging below a certain threshold level. Moreover, the implemented indirect field oriented control (IFOC) of IM is practically validated using a four-poles squirrel-cage induction machine.
