Abstract
In the manufacture of components and systems for electromobility, almost all functional and safety-relevant components are now subject to limit values for particle cleanliness. What began 25 years ago for individual components in the area of the power train for combustion engines can now be found across the board in systems of the electric power train.
So far, attempts have always been made to ensure the necessary component cleanliness through measures in production and assembly. However, it is now becoming increasingly clear that the required technical cleanliness cannot be reliably produced with this approach alone. In this article, the limits of technical cleanliness for the materials and manufacturing processes used today will be shown. Even if further optimization and investments are made here, this alone is not expedient.
The only viable way to achieve the high cleanliness specifications is to integrate development and construction into the process in a different way than before. The degree of cleanliness to be achieved in the later product and at what cost is already largely determined by the design. So far, development has usually only been responsible for creating the cleanliness specifications, but not for their accessibility. How a rethinking can take place here and what expedient approaches there are for this will be presented and explained in the article.
