Abstract
There is provided a method and article of manufacture for monitoring an electrical energy storage device for a system. The method comprises stabilizing the electrical energy storage device. Once the device is stabilized, a discrete electrical load is cyclically applied to the electrical energy storage device and state variables of the electrical energy storage device are monitored. A resistance of the electrical energy storage device is determined, and a remaining useful life parameter of the electrical energy storage device is determined based upon the determined resistance.
