    Abstract: Discussed is a battery pack including a structure for reducing damage to a component of a Battery Management Unit (BMU), and more particularly, to a battery pack with a structure that mitigates a concentration of stress caused by external vibration or force on the BMU mounted on a BMU mounting part and facilitates the assembly of the BMU, so that the BMU can be stably fixed to an assembled position to reduce damage to BMU components. The battery pack includes a partition configured to divide cell mounting parts and the BMU mounting part, and the partition have a stress concentration relaxation structure.

    CPC classification number: H01M50/24 B23K20/10 H01M50/244

    Abstract: Discussed is a battery pack case that may include a first case and a second case configured such that outer peripheries of the first case and the second case are coupled to each other by ultrasonic welding, wherein the outer periphery of the first case comprises a flat portion and a projecting portion formed as a result of a middle of the first case in a thickness direction projecting from the flat portion. Further, the outer periphery of the second case comprises a receiving portion configured to be fused with the projecting portion and an outer guide portion projecting from the receiving portion so as to face the flat portion, and a control rib projecting from at least a part of the flat portion is provided.
