The present disclosure relates to a method of fabricating a cooling plate 5 for a battery module comprising: taking first and second planar substrates 22 and selectively etching material from at least one of the faces of the substrates 22 to form at least one fluid passageway 26 therein; juxtaposing the planar substrates 22 in a face to face arrangement with the fluid passageways 26 facing inwards; and joining the two substrates 22 each to the other. Etching may be accomplished by chemical etching, plasma etching and ion beam milling. Optionally, both substrates 22 have material selectively etched therefrom in spatial arrangements which are respectively the mirror image of one another so that the fluid passageways may be brought in to registration to form a single passageway 30 when the plates 22 are joined. The present disclosure also relates to a traction battery (52, fig 5) having at least one battery cell (50-1 , 50-n, fig 5) arranged in thermal communication with at least one of said cooling plates 5; and to a vehicle (9, fig 5) incorporating the cooling plate 5. |
