Abstract: A system for starting an internal combustion engine includes a battery system, a charger to receive DC battery power from the battery system and convert the power to a DC charging current, a supercapacitor array having a plurality of supercapacitor cells connected to the charger to receive the DC charging current therefrom, and a motor starter to start the internal combustion engine responsive to a DC input from the supercapacitor array. The charger modifies a voltage of the supercapacitor cells in an on-demand fashion, with the charger programmed to provide DC charging current to the supercapacitor array to hold the supercapacitor cells at a first voltage, receive a bump-up command indicative of an upcoming engine start and, responsive to receiving the bump-up command, provide DC charging current to the supercapacitor array to increase a voltage of the supercapacitor cells temporarily to a second voltage higher than the first voltage.

Abstract: A protection device for connection to a power bus of an electrical power system includes a bidirectional clamping apparatus configured to conduct current when a voltage across the bidirectional clamping apparatus is more positive than a positive voltage standoff and when the voltage across the bidirectional clamping apparatus is more negative than a negative voltage standoff; and a control element in series with the bidirectional clamping apparatus, the control element and the bidirectional clamping apparatus providing a current path across the power bus when a magnitude of a voltage on the power bus exceeds a positive voltage threshold or a negative voltage threshold, the positive voltage threshold being greater than the positive voltage standoff of the bidirectional clamping apparatus and the negative voltage threshold being more negative than the negative voltage standoff of the bidirectional clamping device.
