WHAT IS CLAIMED IS:

1. A rechargeable battery pack comprising:

a housing;

a plurality of cells located within said housing;

a heat sink for dissipating heat from said plurality of cells, wherein said plurality of cells are encapsulated by said heat sink; and

at least one elongated cooling channel to provide for active cooling, said elongated cooling channel within said housing and at least partially defined by said heat sink.

2. The rechargeable battery pack as in claim 1, wherein each of said plurality of cells is immediately adjacent to said heat sink.

3. The rechargeable battery pack as in claim 1, wherein at least a portion of said heat sink is exposed to the ambient environment.

4. The rechargeable battery pack as in claim 1, wherein said heat sink is located internally within said housing.

5. The rechargeable battery pack as in claim 1, wherein said heat sink further comprises a plurality of ribs.

6. The rechargeable battery pack as in claim 5, wherein said plurality of ribs are located on the portion of said heat sink that is at least partially exposed to the ambient environment.

7. The rechargeable battery pack as in claim 1, wherein said at least one elongated cooling channel is centrally located within said housing and is completely defined by said heat sink.

8. The rechargeable battery pack as in claim 1, further including a cooling medium to flow through said at least one elongated cooling channel.

9. The rechargeable battery pack as in claim 8, wherein said cooling medium is selected from the group consisting of air, water, or coolant.

10. The rechargeable battery pack as in claim 1, wherein a thermally conductive material is disposed between said heat sink and said each of said plurality of cells.

11. The rechargeable battery pack as in claim 1, wherein said plurality of cells are sealed within said housing.

12. A rechargeable battery pack comprising:

a housing;

a plurality of cells located within said housing, wherein no single cell is completely surrounded by adjacent cells;

a heat sink for dissipating heat from said plurality of cells, wherein said plurality of cells are encapsulated by said heat sink; and

at least one elongated cooling channel to provide for active cooling, said elongated cooling channel within said housing and at least partially defined by said heat sink.

13. The rechargeable battery pack as in claim 12, wherein each of said plurality of cells is immediately adjacent to said heat sink.

14. The rechargeable battery pack as in claim 12, wherein said plurality of cells are selected from the group consisting of cylindrical cells, rectangular, square, oval, triangular, or disc-shaped.

15. The rechargeable battery pack as in claim 12, wherein said plurality of cells include fifteen individual cells arranged in two offset rows of cells, each row being positioned relative to another.

16. The rechargeable battery pack as in claim 12, wherein said plurality of cells are arranged in two separate groups of cells.

17. The rechargeable battery pack as in claim 12, wherein said at least one elongated cooling channel is centrally located within said housing and is completely defined by said heat sink.

18. The rechargeable battery pack as in claim 12, further including a cooling medium to flow through said at least one elongated cooling channel.

19. The rechargeable battery pack as in claim 12, wherein said plurality of cells are sealed within said housing.

20. A rechargeable battery pack comprising:

a housing;

a first and a second heat sink;

a first battery group, said first battery group comprising a plurality of cells, wherein said first battery group is encapsulated by said first heat sink;

a second battery group, said second battery group comprising a plurality of cells, wherein said second battery group is encapsulated by said second heat sink; a thermally conductive material to provide for intermediate heat transfer from said plurality of cells to said first and second heat sinks; and

at least one elongated cooling channel for active cooling, said elongated cooling channel being located within said housing and at least partially defined by said first and second heat sinks.
