5. The cooling jacket of claim 3 , wherein the cavities include a first draft and a second draft to secure the energy storage cell with a wedge fit.
6. The cooling jacket of claim 2 , wherein the second surface includes a plurality of ribs to prevent crushing or warping of the energy storage cells.
7. The cooling jacket of claim 2 , wherein the second surface includes a plurality of integral fastening points.
8. The cooling jacket of claim 7 , wherein the plurality of integral fastening points are provided to include one of welding and gluing.
9. The cooling jacket of claim 1 further includes integrated openings to receive the energy storage cell terminals.
10. A battery pack for retaining a plurality of energy storage cells comprising:
a first plate provided with an inlet opening to allow a coolant;
a second plate provided with an outlet opening to exit the coolant;
a group of stacked cooling jackets are provided in between the first plate and the second plate, each of the group of stacked cooling jackets comprising:
a first half, comprising:
a first half first end,
a first half second end disposed opposite the first half first end, and
a first half coolant opening through the first half proximate the first half first end;
a second half, comprising:
a second half first end,
a second half second end disposed opposite the second half first end, and
a second half coolant opening through the second half proximate the second half first end, wherein the first half and the second half are substantially identical and flip-ably connected to each other with the first half first end disposed adjacent to the second half second end and the second half first end disposed adjacent to the first half second end, wherein the flip-ably connected first half and second half are in direct contact with one another;
a channel provided in between the first half and the second half to allow fluid flow within the cooling jacket between the first half coolant opening and the second half coolant opening; and
the coolant flows in the channel provided between the first half and the second half.
11. The battery pack of claim 10 , wherein the plurality of energy storage cells retained in the stacked cooling jackets are set to a common plane to mount a buss bar.
12. The battery pack of claim 10 , wherein the cooling jacket includes integrated openings to receive the energy storage cell terminals.
