Case Study

Electrical connections for battery systems

The challenge

A busbar system made of copper was to be developed for the drive battery of a fully electric vehicle. The task was to compensate for the thermally induced linear expansion and the dynamic driving vibration load.

The smk solution

We developed the entire busbar system exactly according to the customer’s specifications. In the process, we were able to identify potential for optimising the use of materials. Depending on the required degree of freedom of movement, different copper flex elements are used at specific points. In this way, we were able to implement all the requirements for the bus bar system without any problems.

The successful result

Our customer received an efficiently manufactured, functioning battery contacting system that includes extruded, plastic-moulded as well as flexible busbars.
