Abstract
This application relates to the technical field of energy storage devices, and in particular, to a box body, a battery pack, and a device. The box body includes a first beam and a second beam. The first beam and the second beam intersect each other, and are connected by a connecting portion, and partition the box body into a plurality of accommodation spaces. The first beam includes a body and a recess. The recess is recessed inward relative to the body. The connecting portion is disposed in the recess. In this way, a joint position between the first beam and the second beam will not protrude from a lateral surface of the first beam, thereby preventing a short circuit of a battery cell caused by puncture of or damage to an insulation film outside the battery cell, and improving safety performance of the battery.
