The battery pack according to the present disclosure may simplify the assembling process and reduce the material cost since the bolting process may be omitted when the BMS plate 30 is coupled, compared to the conventional battery pack.

In addition, since the battery pack is cooled by the air ducts 20 disposed at both sides of the cell assembly, the space utilization in the cell thickness direction may be enhanced. Also, by means of the truss structure 21 provided inside the air duct 20, it is possible to sufficiently secure the mechanical stiffness and improve the cooling performance.

The present disclosure has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the disclosure, are given by way of illustration only, since various changes and modifications within the scope of the disclosure will become apparent to those skilled in the art from this detailed description.

If the present disclosure is applied, the assembling work for inserting the BMS plate into the battery pack is improved, thereby reducing a process number and material costs, compared to the conventional bolting assembling work.
