Abstract
A vehicle includes a combustion engine (CE) and electric machine (EM) coupled to an energy storage system (ESS) and a controller, which are configured to maximize ESS/battery charge recovery during high performance operation. The controller commands the CE to generate power exceeding road load power and power demand (PD), to recharge the ESS at a maximum rate for rapid ESS charge recovery. Responsive to the PD, the CE generates a maximum power to drive the EM to recharge the ESS at a maximum rate during acceleration, deceleration, and when maintaining velocity of the vehicle, and to generate positive torque and discharge the ESS when PD and road load power exceeds CE maximum power, according to the PD, road load power, and maximum ESS charge rate. Power regeneration during deceleration may also be enabled for the electric machine and/or regenerative brakes, which further maximizes ESS SoC recovery during high performance operation.
