On-board battery assembly

An on-board battery assembly comprising:

• a cell stack that includes a plurality of cell modules, which is electrically connected in series with each other, wherein:
• each of the plurality of cell modules has a side surface that extends along a longitudinal axis of each of the plurality of cell modules, the plurality of cell modules being integrally arranged such that the side surfaces of the plurality of cell modules are opposed to each other along a width axis that is orthogonal to the longitudinal axis;
• and
• the cell stack has one side face that extends generally along the width axis;
• a blowing member that is provided adjacent the one side face of the cell stack, the blowing member having a blow-out port that has a dimension generally equivalent to a dimension of the one side face of the cell stack measured along the width axis, the blowing member supplying cooling air to the cell stack through the blow-out port;
• and
• a control component that is electrically connected with the plurality of cell modules, the control component being adapted to control electric power supply from the cell stack, wherein:
• the blowing member includes a casing that has:
• a suction port adapted to suction air generally in a direction of the width axis;
• and
• a flow channel defined within the casing, the flow channel connecting the suction port with the blow-out port, the flow channel has a dimension along the width axis, which becomes greater toward the blow-out port;
• and
• the control component is provided in a space defined between the casing and a plane, which is perpendicular to the width axis, and which includes an end portion of the one side face of the cell stack along the width axis.
