Battery pack and power-consuming device

Abstract

Battery pack, characterized in that the battery pack comprises: a base plate, several batteries fixedly arranged on the base plate along a first direction, each individual battery comprising a metal housing, the metal housing comprising two opposing first wall sections and two opposing second wall sections, one area of ​​the first wall section being larger than one area of ​​the second wall section, the first wall sections of two adjacent batteries being opposite each other, an insulating layer being arranged on an outer surface of the first wall section, the first direction being perpendicular to the first wall section, the insulating layer partially covering the first wall section so that the first wall section has a second exposed area.wherein a first section at least partially covers the second exposed area, wherein the metal housing further comprises a bottom surface, the bottom surface being arranged facing the base plate, wherein a first exposed area is arranged on the bottom surface, an insulating adhesive comprising a first section and a second section, the first section being arranged between two adjacent batteries and firmly connecting the two adjacent batteries to each other, wherein at least a part of the second section being arranged between the first exposed area and the base plate and firmly connecting the battery to the base plate, furthermore a separating element, the separating element being located between the first wall sections of two adjacent batteries, wherein a part of the separating element being firmly bonded to the insulating adhesive, wherein the insulating layer and the insulating adhesive satisfy the following: 0.001 mm ≤ [(2D1+D2) / 2L] × H ≤ 2.5 mm,where D1 is a thickness (unit: mm) of the insulating layer in the first direction, where D2 is a thickness (unit: mm) of the first section in the first direction, where L is a length (unit: mm) of the battery in the first direction, where H is a distance (unit: mm) between an upper end of the first section and a top surface of the base plate.
