A vehicle is provided including a battery module with front and rear battery cell arrays arranged generally parallel to and spaced apart from one another. The battery module includes a cover having an inlet port proximate to the front battery cell array and arranged obliquely thereto. A blower unit is configured to draw air through the inlet port such that a first portion of the air travels into the front battery cell array. A tray cooperates with the front battery cell array to define a passageway configured to direct a second portion of the air underneath the front battery cell array. The tray also defines a ramp underneath, and extending substantially a length of, the rear battery cell array and is configured to direct the second portion of air into the rear array.
