A battery module includes an array of electrochemical cells, and a frame configured to support the cells within the battery module, the fame encircling the array in such a way as to overlie the cell sidewall of each cell and expose the cell first end and the cell second end of each cell. The frame is surrounded by a spacer. The spacer includes a first wall portions that faces the cell first ends, and a second wall portion that faces the cell second ends. The first and second wall portions include grooves that serve as coolant fluid passages. The frame is disposed in the spacer interior space in such a way that each of the cell first ends and each of the cell second ends are exposed to the fluid passages of the first wall portion and the second wall portion.
