Systems and methods for providing charge to an energy storage system of a vehicle are provided. The method may include receiving, by a vehicle control system, an indication that a vehicle is coasting, slowing, and/or braking. Based on the received indication, engaging, by the vehicle control system, an electric motor coupled to an internal combustion engine to generate electric charge and provide the generated electric charge to the energy storage system, and while engaging the electric motor to generate electric charge, deactivating, by the vehicle control system, a cylinder of the internal combustion engine by maintaining an inlet valve of the cylinder and an exhaust valve the cylinder in a constant position, such as a closed position. In some instances, the inlet valve and exhaust valve may be maintained in an open state to further slow the vehicle.
