Abstract

A thermally fitted interconnect couples energy storage cells without the use of additional materials of fasteners. Variations of the interconnect can be used to facilitate fitting of multiple energy storage cell with multiple cell to cell spacings in a rapid and inexpensive manner.

Claims (10)

1. A method of using an interconnect, comprising:

providing an energy storage device, the device including a terminal having a first distance;

providing an interconnect, the interconnect including a void having a surface defined by a second distance;

subjecting the terminal and the interconnect to different temperatures;

positioning the terminal within the void; and

allowing the terminal and the interconnect to equilibrate to substantially the same temperature to form a bond between the surface and the terminal.

2. The method of claim 1 , wherein before subjecting the terminal and the interconnect to different temperatures, and before positioning the terminal within the void, at the same temperature the first distance is shorter than the second distance.

3. The method of claim 2 , wherein the device comprises a capacitor.

4. The method of claim 1 , wherein at the same temperature, the device, the terminal, and the interconnect comprise a self-supporting assembly.

5. The method of claim 1 , further comprising passing at least 1000 amps of current through the terminal and the interconnect.
