description A system and method of managing power in a hybrid vehicle are provided. The system includes an engine, first and second electronic power components, a power storage device, and a controller. The power storage device is configured to supply a power output to the second electronic power component necessary for the second electronic power component to drive a second set of drive wheels, in an electronic all-wheel drive mode. In steep grade environments, the power storage device is depleted at a higher rate, and may require a power input in addition to the power input of a conventional charge to adequately supply the second electronic power component with adequate power. To provide this power, the controller executes a series of control steps to increase a power output of the first electronic power component, by increasing the speed of the engine, thereby providing continuous power to the power storage device.
