Patent ID: 8242624

Claim:
An electric accumulator for selectively operating an aircraft device, comprising: an ultra-capacitor for storing electrical energy; an input connector configured to couple the ultra-capacitor to a power source; an output connector configured to couple both the ultra-capacitor and the power source to the aircraft device; and a power distribution controller operatively connected to the input connector and the output connector for controlling the flow of electrical energy to and from the ultra-capacitor, the power distribution controller configured to: determine power demand on the power source; selectively close the input connector to charge the ultra-capacitor by allowing electrical energy to flow into the ultra-capacitor if the power demand is low; selectively open the input connector to restrict electrical energy from flowing into the ultra-capacitor if the power demand is high; and selectively close the output connector to power the aircraft device using the electrical energy from both the ultra-capacitor and the power source by allowing it to flow to the aircraft device.
