Efficiency-Based Energy Management Strategy of a Dual-Motor All-Wheel Drive Electric Vehicle

The design of an energy management strategy (EMS) has a considerable impact on the operation of electric vehicles. In particular, a robust EMS can increase the battery lifetime and reduce its rated parameters degradation. This paper presents an efficiency-based EMS for a dual-motor all-wheel drive electric vehicle developed for the IEEE VTS Motor Vehicles Challenge 2021. The proposed solution aims to maximize the efficiency of the two electrical machines in order to minimize the state of charge depletion of the battery installed into the vehicle. Simulation results for different speed profiles are reported, demonstrating the effectiveness of the EMS proposed
