Abstract

The invention relates to the technical field of battery production, in particular to a battery pack. The battery pack comprises a box body, a wiring harness plate and a plurality of battery cells. The box body comprises a box bottom and a box wall. The box wall is connected to the box bottom. A plurality of first grooves are formed in the box bottom. The wiring harness plate is opposite to the box bottom and connected to the box body. The side, close to the box bottom, of the wiring harness plate is provided with a plurality of second grooves. The number of the second grooves is equal to the number of the first grooves. The second grooves correspond to the first grooves one to one. The openings of the second grooves face the box bottom. The openings of the first grooves face the wiring harness plate. In the corresponding set of the first groove and the second groove, one end of the corresponding battery cell is placed in the first groove, and the other end of the battery cell is installed in the second groove. A module frame is omitted, the structural layer outside the battery cells is omitted, the weight of the battery pack is reduced, and the mass and energy density of the battery pack can be improved.

Description

technical field [0001] The present application relates to the technical field of battery production, in particular to a battery pack. Background technique [0002] The battery pack in the prior art includes a box body, a bottom plate, a side plate, an end plate and a plurality of battery cells. The end plate, the box wall and the box bottom are connected to each other to form a module frame; multiple battery cells are bonded by structural adhesive to form a battery cell The cell group is fixed in the module frame to form a cell module, and the cell module is placed in the box as a whole. [0003] In the existing battery pack, since the battery cell is provided with a two-layer structure of a module frame and a box body, and the module frame is made of metal, the weight of the entire battery pack is increased and the mass energy density of the battery pack is reduced. Contents of the invention [0004] The embodiment of the present application provides a battery pack, whic...
