Abstract
In a hybrid vehicle having an internal combustion engine that is assisted by an electric motor powered by a traction battery, the electric motor is operated in a generating mode to charge the vehicle battery during periods when neither acceleration assist nor regenerative braking are being performed. Torque of the electric motor is adjusted by a controller to generate a battery charge current which regulates the voltage of the battery to a selected setpoint. The setpoint is determined as a function of vehicle operating parameters, including but not limited to battery temperature.
