CLASSIFICATION ## Abstract An exemplary embodiment includes a method of sealing battery cooling plates. ## Claims ### Claim 1 A battery comprising a battery cell positioned between a first cooling plate and a second cooling plate, the first and second cooling plates being supported by frame segments, a first inlet header extension provided extending in an upward direction and a second inlet header extension provided extending in a downward direction from a plane extending through the main portion of the first cooling plate, a first outlet header extension provided extending in an upward direction and a second outlet header extension provided extending in a downward direction from a plane extending through the main portion of the second cooling plate, and wherein the inlet and outlet extensions are provided by at least one of the frame segments, first cooling plate or second cooling plate or a combination thereof. ### Claim 2 (depends on 1) A battery as set forth in claim 1 further comprising a seal positioned to provide one of a plate-to-plate seal or a frame segment-to-plate seal. ### Claim 3 (depends on 2) A battery as set forth in claim 2 wherein the seal is one of an O-ring or compression seal. ### Claim 4 (depends on 2) A battery as set forth in claim 2 wherein the seal is a one piece seal that wraps around a portion of the frame segment to provide a frame segment-to-plate seal between the frame segment and the first cooling plate and a frame segment-to-plate seal between the frame segment and the second cooling plate. ### Claim 5 (depends on 2) A battery as set forth in claim 2 wherein the seal is a compression seal. ### Claim 6 A battery comprising a battery cell positioned between a first cooling plate and a second cooling plate and at least one header defined circumferentially by first and second header inlet extensions, the first inlet header extension provided extending in an upward direction and the second inlet header extension provided extending in a downward direction from a plane extending through the main portion of the first cooling plate, a portion of the first inlet header extension being received in one of the first cooling plate or second cooling plate and a portion of the second inlet header extension being received in the other of the first cooling plate or second cooling plate, a first outlet header extension provided extending in an upward direction and a second outlet header extension provided extending in a downward direction from a plane extending through the main portion of the second cooling plate, a portion of the first outlet header extension being received in one of the first cooling plate or second cooling plate and a portion of the second outlet header extension being received in the other of the first cooling plate or second cooling plate, and wherein the inlet and outlet extensions are provided by at least one of a frame, the first cooling plate or the second cooling plate or a combination thereof. ### Claim 7 A battery comprising a battery cell positioned between a first cooling plate and a second cooling plate and a header defined by at least frame segments, the first and second cooling plates being supported the frame segments, a first inlet header extension provided extending in an upward direction and a second inlet header extension provided extending in a downward direction from a plane extending through the main portion of the first cooling plate, a portion of the first inlet header extension being received in one of the first cooling plate or second cooling plate and a portion of the second inlet header extension being received in the other of the first cooling plate or second cooling plate, a first outlet header extension provided extending in an upward direction and a second outlet header extension provided extending in a downward direction from a plane extending through the main portion of the second cooling plate, a portion of the first outlet header extension being received in one of the first cooling plate or second cooling plate and a portion of the second outlet header extension being received in the other of the first cooling plate or second cooling plate, and wherein the inlet and outlet extensions are provided by at least one of the frame segments, first cooling plate or second cooling plate or a combination thereof. ### Claim 8 (depends on 6) The battery of claim 6 wherein the header is also defined by at least one seal. ### Claim 9 (depends on 7) The battery of claim 7 wherein the header is also defined by at least one seal. ### Claim 10 A battery comprising a battery cell positioned between a first cooling plate and a second cooling plate, a first inlet header extension provided extending in an upward direction and a second inlet header extension provided extending in a downward direction from a plane extending through the main portion of the first cooling plate, a first outlet header extension provided extending in an upward direction and a second outlet header extension provided extending in a downward direction from a plane extending through the main portion of the second cooling plate, and a seal positioned to provide seal wherein the inlet and outlet extensions are provided by at least one of a frame, the first cooling plate or the second cooling plate or a combination thereof. ### Claim 11 (depends on 10) The battery of claim 10 wherein the seal is separate component and is position between adjacent plates to provide a plate to plate seal. ### Claim 12 (depends on 10) The battery of claim 10 wherein the seal is separate component and is position between a plate and a frame to provide a plate to frame seal.
