Abstract
A method of modifying the charging target for the state-of-charge (SOC) of a hybrid vehicle battery in response to a sudden power draw includes determining that the hybrid vehicle has entered a steep grade environment, adjusting a power management scheme of the hybrid vehicle from a standard charging mode to an aggressive charging mode, and operating the hybrid vehicle operated using the adjusted power management scheme. The charging target may include both an immediate charging target and an ultimate charging target, where the immediate charging target is less than the ultimate charging target, and where adjusting a power management scheme from a standard charging mode to an aggressive charging mode includes increasing the immediate charging target.
