Battery pack and power-consuming device

Abstract

Battery pack, characterized in that it comprises: a box body, wherein the box body comprises an enclosed frame and a base plate, wherein the base plate and the enclosed frame form a receiving space, wherein at least one longitudinal beam is arranged in the receiving space, wherein the at least one longitudinal beam extends along a first direction and is firmly connected to the enclosed frame in order to divide the receiving space into several battery compartments which are arranged one after the other along a second direction;Several battery sets permanently attached to the base plate, the several battery sets each being housed in several battery compartments, the battery set comprising several batteries arranged sequentially along the first direction, the battery having a bottom end surface and a top end surface along a third direction, the bottom end surface of the battery being attached to the top of the base plate, the first direction, the second direction, and the third direction being perpendicular to each other; and several boundary plates, the boundary plates being designed to be attached to the top end surfaces of the at least two batteries, the sum of the maximum dimensions of the longitudinal beams in the second direction being A, the sum of the maximum dimensions of the boundary plates in a single battery compartment being B, the units for A and B being mm, and 0.2 ≤ A / B ≤ 4.5.
