Example

[0034] See figure 2 , 3 , A first embodiment of the battery module of the present invention includes a plurality of battery cores 3, a frame 4 accommodating the plurality of battery cores 3, and four are respectively fixed to the plurality of battery cores 3 and form electrical Connected conductive electrode sheets 5 (only two are visible due to the angle).

[0035] Each conductive electrode sheet 5 includes a conductive body 51 having a conductive portion 511 and a plurality of through holes 512, and two welding bodies 52. Each welding body 52 has a first welding surface 521 and a second welding surface 522. The thickness of the plurality of welding bodies 52 is smaller than that of the plurality of conductive bodies 51, and the material of the plurality of conductive bodies 51 is copper, and the material of the plurality of welding bodies 52 is nickel. The multiple through holes 512 correspond to the positions of the multiple battery cells 3 respectively. The plurality of fir...

Abstract

Disclosed is a battery module. The battery module comprises a plurality of battery cells, and a plurality of conductive pole pieces electrically connected with the multiple battery cores; each conductive pole piece comprises a conduction body with multiple through holes, and at least one welding body fixedly connected to the conduction body; the multiple through holes are corresponding to the positions of the multiple battery cells; the thickness of the welding body is lower than that of the conduction body; and each welding body has a first welding surface electrically connected with the multiple battery cells, and a second welding surface positioned on the side opposite to the first welding surface and electrically connected with the conduction body. When the battery module needs to be welded, the welding body with relatively thin thickness is welded with the multiple battery cells; and in electric energy transmission, the conduction body with relatively thick thickness is utilized so as to provide a relatively large conductive area and heat conducting area.

Description

technical field [0001] The invention relates to a battery module, in particular to a conductive electrode sheet of the battery module. Background technique [0002] Existing vehicles (such as: motorcycles, automobiles, electric vehicles) need a battery module to supply electric energy in order to maintain operation. refer to figure 1 A traditional battery module includes a plurality of battery cells 1 and a plurality of conductive electrode sheets 2, and the plurality of conductive electrode sheets 2 are welded to the plurality of battery cells 1, so that the plurality of battery cells 1 are connected in series or in parallel, thereby obtaining a proper power. [0003] When the electric energy is transmitted to the plurality of conductive electrode sheets 2 , part of the electric energy will be converted into heat energy, causing the temperature of the battery module to rise. If the battery module is kept at high temperature for a long time, not only will the cycle life o...
