Disclosed is a battery pack (200). The battery pack comprises a battery cell module (201), two first side covers (10) and two second side covers (20). The battery cell module (201) comprises a plurality of battery cells (2015) stacked in a first direction (X), and a first groove (2012) extending in the first direction (X) is formed at each of the two ends of a first side edge of the battery cell module (201). In a second direction (Y), the two first side covers (10) are arranged on two opposite sides of the battery cell module (201). First bodies (12) of the two first side covers (10) are substantially parallel to a third direction (Z) of the battery cell module (201), each first side cover (10) is provided with an abutting portion (11), the abutting portion (11) extends from the edge of the first side cover (10) and is substantially perpendicular to the first body (12) of the first side cover (10), and the abutting portion (11) is connected to groove walls (2013, 2014) of a first groove (2012) of the battery cell module (201), the second direction (Y) is perpendicular to the third direction (Z), and the first direction (X) is perpendicular to the second direction (Y) and the third direction (Z) at the same time. In the third direction (Z), the two second side covers (20) are arranged on two opposite sides of the battery cell module (201), the two second side covers (20) are substantially parallel to the second direction (Y), and the two second side covers (20) are fixed to the two first side covers (10). The battery cell module (201) is fixed by embedding the abutting portion (11) into the first groove (2012), and the installation is convenient.
