Abstract

Thermal protection is provided in systems utilizing high-current double-layer capacitors.

Claims

1. A method of reducing a double-layer capacitor temperature, comprising the steps of:

providing one or more double-layer capacitor;

coupling the one or more double-layer capacitor to an interconnection;

passing a current through the interconnection and the double-layer capacitors; and

using the interconnection to reduce a temperature of the double-layer capacitors based on a temperature external to the double-layer capacitor.

2. The method of claim 1, wherein the interconnection comprises a thermal contactor.

3. The method of claim 1, wherein the interconnection comprises a thermal fuse.
