The IEEE VTS Motor Vehicles Challenge 2021 focuses on the design of an energy management strategy (EMS) for a dual-motor all-wheel drive (AWD) electric vehicle (EV) of which the reference model is given from an urban EV developed at the University of Sherbrooke. The participants will develop their EMS to allocate the traction forces between the front and rear axles and also the mechanical and electrical braking forces of each axle.
The ultimate objective of the EMS is to minimize the battery state-of-charge (SoC) depletion respecting the torque constraints of the EDs and the temperature constraints of the battery cell. The participants will design the hybridization of a battery and supercapacitor based on commercial vehicle and cell models. Then, they will develop the real-time EMS to minimize the objective function of battery SOC, supercapacitor charge-sustaining, battery cell current rms value, and its variations.
