Method for Producing a Cell-Contacting System for a Battery Module of a Vehicle, Cell-Contacting System and Battery Module

A method for producing a cell-contacting system for a battery module of a vehicle, the method comprising:

• producing a plurality of connection elements for respective electrical connection of adjacent battery cells of the battery module, and
• providing a holding device for holding the connection elements, wherein:
• each of the connection elements is produced such that the connection element has a region having a reduced stiffness, wherein the region having the reduced stiffness has a lower mechanical stiffness in comparison with other regions of the connection element,
• the connection elements are produced such that the connection elements are arranged beside one another in a first row and a second row, and the adjacent battery cells are connectable to one another alternately in the first row and the second row,
• the holding device is provided by electrically insulating support elements,
• a first main body formed as a strip or as an elongated metal sheet for production of the connection elements in the first row is connected to a first support element of the support elements and to a second support element of the support elements,
• a second main body formed as a strip or as an elongated metal sheet for the production of the connection elements in the second row is connected to the second support element and to a third support element of the support elements, and
• initially the first main body and the second main body are provided and are connected to the support elements, and then the connection elements are produced from the first main body and the second main body.

A cell-contacting system for a battery module of a vehicle, the cell-contracting system comprising:

• a plurality of connection elements for respective electrical connection of adjacent battery cells of the battery module, wherein each of the connection elements has a region having reduced stiffness, and the region having the reduced stiffness has a lower mechanical stiffness in comparison with other regions of the connection element, and
• a holding device for holding the connection elements, wherein:
• the connection elements are arranged beside one another in a first row and a second row, and the adjacent battery cells are connectable to one another alternately in the first row and the second row,
• the holding device comprises electrically insulating support elements, and the connection elements are produced from two main bodies formed as strips or as elongated metal sheets connected to the support elements, wherein
• the support elements include a first support element, which is connected to an upper side of each of the connection elements in the first row,
• the support elements include a second support element, which is connected to an underside of each of the connection elements in the first row and to the upper side of each of the connection elements in the second row, and
• the support elements include a third connection element, which is connected to the underside of each of the connection elements in the second row.
