POWER BATTERY MODULE

摘要

A power battery module (100) includes a battery pack (9), an upper case (6), a lower case (7) matched with the upper case (6), and at least one baffle plate (8) longitudinally disposed at a lateral side of the battery pack (9) between the upper case (6) and the lower case (7). At least one projection (76) is provided on at least one of the inner surface of the upper case (6) and the inner surface of the lower case (7). The upper case (6) and the lower case (7) fix the battery pack (9) in a first direction, the baffle plate (8) fixes the battery pack (9) in a second direction, the projection (76) fixes the battery pack (9) in a third direction, and the first direction, the second direction and the third direction are mutually orthogonal. The power battery module (10) achieves stable three-dimensional fixing with simplified assembly process.
