at least one cartridge to accommodate the plurality of cells and the plurality of heat plates, wherein the plurality of cells includes a first cell group, and a second cell group arranged in parallel with the first cell group, wherein the plurality of heat plates includes a first heat plate to absorb heat from the first cell group, and a second heat plate to absorb heat from the second cell group, wherein the cooling channels include a central cooling channel defined between the first and second heat plates, and outer cooling channels defined between outer edges of the first and second heat plates and inner walls of the at least one cartridge, wherein each of the first and second heat plates includes:
a flat plate that contacts least two of the plurality of cells to receive heat from the at least two of the plurality of cells;
a plurality of outer cooling fins that extends in a flow direction of air flowing through the outer cooling channel;
a plurality of central cooling fins that extends in a flow direction of air flowing through the central cooling channel;
an outer connecting member provided between the plurality of outer cooling fins and the flat plate to form the outer cooling channel with the at least one cartridge, the outer connecting member transferring heat from the flat plate to the plurality of outer cooling fins, the plurality of outer cooling fins being arranged at the outer connecting member; and
a central connecting member provided between the plurality of central cooling fins and the flat plate to form the central cooling channel, the central connecting members transferring heat from the flat plate to the plurality of central cooling fins, the plurality of central cooling fins being arranged at the central connecting member, wherein the plurality of outer cooling fins includes inner cooling fins and peripheral, cooling fins, wherein the inner cooling fins of the outer cooling fins have a longer horizontal length than the peripheral cooling fins of the outer cooling fins, wherein the plurality of central cooling fins includes inner cooling fins and peripheral cooling fins, wherein the inner cooling fins of the central cooling fins have a shorter horizontal length than the peripheral cooling fins of the central cooling fins, and wherein at least one of the peripheral cooling fins of the central cooling fins has a bent portion, such that the bent portion of the peripheral cooling fins of the central cooling fins of the first heat plate is forcibly engaged to be connected with the peripheral cooling fins of the central cooling fins of the second heat plate, and the bent portion of the peripheral cooling fins of the central cooling fins of the second heat plate is forcibly engaged to be connected with the peripheral cooling fins of the central cooling fins of the first heat plate.
2. The cell module assembly according to claim 1 , wherein the first beat plate and the second heat plate have the same shape.
3. The cell module assembly according to claim 1 , wherein each of the first and second heat plates further includes an engagement protrusion, to prevent a respective cell of the plurality of cells from moving with respect to each of the outer and central connecting members, the engagement protrusion contacting the respective cell, to absorb heat from the contacted cell.
4. The cell module assembly according to claim 3 , wherein a thermal pad is disposed at an area were the engagement protrusion contacts the respective cell.
5. The cell module assembly according to claim 3 , wherein each of the plurality of cells includes cell packing portions formed by folding ends of a cover that covers the cell, and sealing the folded ends, and wherein the engagement protrusion extends below the cell packing portions.
6. The cell module assembly according to claim 1 , further including at least one covet that encloses the at least one cartridge, wherein the at least one cartridge is formed with a side opening that communicates with the outer cooling channel, and wherein the at least one cover is formed with a side communication hole that communicates with the side opening.
7. The cell module assembly according to claim 1 , wherein the at least one cartridge is formed with a central opening that communicates with the central cooling channel.
8. The cell module assembly according to claim 7 , further including at least one cover that encloses the at least one cartridge, wherein the at least one cover is formed with a central communication hole that communicates with the central cooling channel.
9. The cell module assembly according to claim 1 , wherein the at least one cartridge includes a plurality of cartridges, wherein the plurality of cartridges is vertically stacked while being laterally connected, wherein the cooling channels extend substantially in parallel, and wherein each of the plurality of cartridges is formed with a groove and a protrusion, for engagement of adjacent ones of the plurality of cartridges.
