ENERGY MANAGEMENT IN HEAVY DUTY TRUCKS USING INEFFICIENT MOTOR OPERATION

An energy management method for a range-extended electrified vehicle (REEV) includes, in response to enablement of an inefficiency mode of the REEV, utilizing inefficient motor loss maps specifically for the inefficiency mode and separate from maximum efficiency motor loss maps, determining motor torque commands for an electric motor of the REEV using a driver torque request, the inefficient motor loss maps, and inefficient motor torque command mappings specifically for the inefficiency mode and separate from maximum efficiency motor torque command mappings, and controlling the electric motor using the determined motor torque commands to generate heat energy and dissipate energy from a battery system of the REEV configured to power the electric motor and thereby create space for storage of energy captured by a regenerative braking system of the REEV.
