The invention relates to the technical field of batteries, and provides a battery pack, an assembling method of the battery pack and a battery cluster. The battery pack comprises a battery box body; the battery assembly, the buffer piece and the first baffle plate are arranged in the battery box body, and the battery assembly comprises a plurality of batteries stacked along a first direction; the buffer piece is located between the first baffle and the battery assembly; and the first baffle plate is detachably connected with the battery box body, so that the first baffle plate moves relative to the battery box body to extrude the buffer piece. The buffering piece is located between the first baffle and the battery assembly, the buffering piece plays a role in isolating the first baffle from the battery assembly, the first baffle extrudes the battery assembly by extruding the buffering piece so as to achieve the compression process of the battery assembly, and the buffering piece provides a certain buffering expansion space for the battery assembly; and the situation that the movement amount of the battery adjacent to the buffer piece is large is avoided. And the first baffle plate is connected with the battery box body, so that the battery assembly is fixed, and the pre-tightening force among a plurality of batteries is improved.
Description
technical field [0001] The present invention relates to the technical field of batteries, and in particular, to a battery pack, a method for assembling the battery pack, and a battery cluster. Background technique [0002] After multiple batteries are stacked in the battery pack, when the baffles are used to press the batteries, the battery may have a large displacement, resulting in excessive pressing force of the battery, which affects the performance of the battery pack. SUMMARY OF THE INVENTION [0003] The invention provides a battery pack, an assembling method of the battery pack and a battery cluster, which can reduce the compressed movement of the battery and improve the use performance of the battery pack. [0004] According to a first aspect of the present invention, there is provided a battery pack comprising: [0005] battery box; [0006] a battery assembly, the battery assembly is disposed in the battery box, and the battery assembly includes a plurality of...
