Vehicle battery cell cooling assembly

A battery cell cooling assembly for a vehicle comprising a cooling vessel having a coolant flow path between an inlet and outlet, cell apertures exterior to the flow path, a first directional directing coolant from the inlet into laterally spaced first sub-channels, a second directional receiving coolant from the first sub-channels and directing it into laterally spaced second sub-channels, the first sub-channels extending transversely between the cell apertures and aligned longitudinally between first aperture ends and second aperture ends of the cell apertures, the second sub-channels extending transversely between the cell apertures and aligned longitudinally between the first sub-channels and the second aperture ends, wherein the first sub-channels provide a first thermal pass by each of the plurality of cell apertures and the second sub-channels provide a second thermal pass by each of the same plurality of cell apertures for temperature control of the cells during operation.
