BATTERY MODULE AND ELECTRICAL DEVICE INCLUDING THE SAME

Disclosed are a battery module and an electrical device including the battery module. The battery module includes: a battery cell array (100), a side plate (200) and an insulation barrier (201). The side plate (200) is arranged corresponding to at least one surface on the outer side of the battery cell array (100) in the circumferential direction; the insulation barrier (201) is arranged between the side plate (200) and the side wall of the battery cell array (100), and protrudes above the battery cell array (100). The battery module may overcome the problem of the existing battery module, that is, the short electrical safety distance between the housing of the battery cell (111) and the side plate (200) of the battery module.
