Title:
BATTERY MODULE
Document Type and Number:
Japanese Patent JP2021047982
Kind Code:
A
Abstract:
To provide a battery module, equipped with a detection mechanism for voltages of a plurality of battery cells, in which electrical connection failure is prevented.SOLUTION: A battery module has a laminate, a binding tool, and a wiring board 50. The laminate comprises: a plurality of power generation elements (battery cells) each of which has a positive electrode and a negative electrode aligned in a manner spaced away from each other in a z-direction; and a plurality of conductive plates 12 which are connected to the electrodes in a manner facing them in the z-direction. The binding tool holds the alignment of the plurality of power generation elements and the conductive plates in the z-direction. A conductive projection 20 extends from each of the plurality of conductive plates. A tip side of the conductive projection has elasticity in a y-direction. The tip side of the conductive projection comes into contact with the wiring board in a manner elastically deformed in the y-direction. Thus, the conductive projection and the wiring board are electrically connected to each other.SELECTED DRAWING: Figure 12
