Abstract

A system of rigid insulating insert separators for mounting energy storage cell canisters within a sealed module of multiple energy storage cell canisters to maintain the exact position of the energy storage cell canisters to eliminate stress and resistance variation at the point of contact between the bus bar interconnections and the cell terminals. The separators also have provision for mounting balancing circuit boards between the energy storage cell canisters and allowing wiring connections between the circuit boards and the bus bar interconnections.

Claims

1. A system for mounting energy storage cell canisters within a multi-cell energy storage module, the energy storage cell canisters having an outer surface, a central longitudinal axis, and opposite ends, comprising:

a plurality of shaped separator inserts to position and support the energy storage cell canisters, the plurality of shaped separator inserts configured to extend substantially perpendicularly relative to central longitudinal axis of the energy storage cell canisters; and

a plurality of bus bar interconnections to electrically connect the energy storage cell canisters.

2. The system of claim 1, wherein the shaped separator inserts are made from a hard plastic insulating material.

3. The system of claim 2, wherein the shaped separator inserts are made from a hard nylon.

4. The system of claim 1, wherein the shaped separator inserts are shaped to match and receive the outer surface of the energy storage cell canisters.

5. The system of claim 1, wherein the shaped separator inserts include holes for wiring access.

6. The system of claim 1, further including cell balancing circuit boards mounted between at least one of rows and columns of energy storage cell canisters and wiring to connect the cell balancing circuit boards to the bus bar interconnections, and wherein the shaped separator inserts, the circuit boards, and wiring are one of a modification, conversion, and retrofit kit for an ultracapacitor module.

7. The system of claim 1, wherein the energy storage cell canisters are ultracapacitors.

8. The system of claim 1, wherein the energy storage cell canisters are batteries.

9. The system of claim 1, wherein the energy storage cell canisters are shaped as a cylinder.

10. The system of claim 1, wherein the energy storage cell canisters are shaped as square cans.

11. The system of claim 1, wherein one or more shaped separator inserts extend along the outer surface of the energy storage cell canisters.

12. The system of claim 1, wherein more than one of the bus bar interconnections have different lengths.

13. The system of claim 1, wherein more than one of the shaped separator inserts have different widths.

14. The system of claim 1, wherein the shaped separator inserts include grooves to mount circuit boards at least partially therein.

15. The system of claim 1, wherein the energy storage cell canisters are organized in at least one of rows and columns, and further including circuit boards disposed parallel relative to central longitudinal axis of the energy storage cell canisters in respective spaces between at least one of rows and columns.

16. The system of claim 15, wherein more than one of the circuit boards are different.

17. The system of claim 15, wherein the circuit boards also contain circuits for reporting the module status external to the multi-cell energy storage module.

18. The system of claim 1, wherein the energy storage cell canisters are organized in at least one of rows and columns, and the shaped separator inserts extend substantially the entire length of at least one of rows and columns in spaces between at least one of rows and columns.

19. The system of claim 1, wherein the energy storage cell canisters are organized in at least one of rows and columns, and the shaped separator inserts extend adjacent both ends of the energy storage cell canisters in spaces between at least one of rows and columns.
