Patent ID: 8010250

Claim:
A method for power management for an aircraft having a plurality of subsystems and a plurality of electrical energy storage devices, the method comprising: determining a power priority for each of the subsystems based on a specific function of each of the subsystems, a sequence of operation of the subsystems, and a forecasted power requirement for operating each of the subsystems; allocating the electrical energy storage devices based on health of each of the electrical energy storage devices and a capability to supply power to the subsystems, wherein the health of each of the electrical energy storage devices depends on a maximum actual capacity of each of the electrical energy storage devices relative to an initial specification of the corresponding electrical energy storage device, and wherein the health of each of the electrical energy storage devices is determined by comparing the maximum actual capacity of each of the electrical energy storage devices to data sets corresponding to various levels of health; providing power from the electrical energy storage devices to the subsystems according to the allocation and to the power priority for each of the subsystems; and controlling the health of the electrical energy storage devices, concurrently with selectively distributing power, based on a plurality of operating status parameters of the electrical energy storage devices.
