Battery module

Abstract

The invention provides a battery module. A second fixing case of the battery module includes at least one guide structure and at least one guide hole. The guide structure, in an accommodation space, extends out from a bottom plate of the second fixing case. The guide hole is arranged in the bottom plate, and the positions of the guide hole and the guide structure are in correspondence. A pin of an electrode piece passes through the guide hole, extends along the guide structure, and is electrically connected to a connection pad of a circuit board. As a result, the pin of the electrode piece can be effectively guided, and a free end of the pin can be disposed on the connection pad of the circuit board. By adopting the above design, not only are wires in the prior art omitted, but also electric connection structures and electric connection programs between the circuit board and a plurality of batteries are simplified, so that the production cost is reduced, and working hours for assembling the battery module are saved.

Description

technical field [0001] The invention relates to a battery module, in particular to a battery module with an electrical connection structure between a circuit board and a battery device. Background technique [0002] With the advancement of science and technology, transportation vehicles have progressed from using gasoline as fuel for automobiles and locomotives to using natural gas as fuel for automobiles and as the power supply for automobiles and locomotives to operate. Bicycles have traditionally been driven by human power. Used as power for the bicycle to operate. Of course, with the gradual reduction of fuel raw materials, rising prices, and the rise of environmental awareness, transportation tools including electric bicycles, electric locomotives, and gasoline-electric vehicles have been developed. [0003] However, with the development of transportation vehicles and the emphasis on electric transportation vehicles towards the green energy industry, battery modules th...

Problems solved by technology

[0006] However, in order to transmit the voltage of the battery device 110 by piercing or lap-welding the pins 113 of the electrode sheet 112 to the wire 130, a plurality of wires 130 and connectors 131 must be used to transmit the voltage of each battery device 110. Therefore, the cost of manufacturing is increased, and in assembly, these wires 130 must be sorted out and plugged between the connector 131 and another connector, which causes inconvenience in assembly and increases production time.

[0007] Especially when other wires (not shown) for connecting to the outside are included, the wires and wires in the entire battery module 100 will be more messy, and it will also cause difficulty in assembly
