Abstract
Electro mobility is becoming increasingly important in the automotive industry, with energy storage becoming the main topic. AVL List GmbH is creating the Battery Innovation Center (BIC) located in Graz in order to address this problem and offer corresponding solutions for the automotive market in the future.
Different types of battery cells are assembled in the BIC in the area of prototype and small series production for a wide variety of vehicles. From electric scooters, cars to heavy-duty vehicles, the cells are assembled to modules and after-wards completed as a compact battery pack for installation in the vehicle. In the course of this process, a flexible production system has to be designed that enables the assembly of battery modules for all variants.
The Institute of Production Engineering acts as a project partner and supports this project with master's theses, among other things. This work deals with quality assurance in this form of production unit, which should be flexible and expandable. For this purpose, the structure and basics of the battery were worked out and subsequently, based on previous AVL projects, a flexible production process for battery module production for all cell types was designed.
Quality assurance can be found in many areas of the production process. The main focus was placed on the electrical and optical inspection of the battery cells before assembly, as well as on data management.
The topic of data management deals with data storage and data transfer as well as traceability of the product. For this purpose, types of identification options were compared with each other and possible solutions were proposed.
For the electrical and optical inspection of the battery cells, solution variants were developed and evaluated in order to finally obtain a flexible and sustainable quality assurance process.
Elaborations and solutions can afterwards be adopted and used as analogies for downstream process steps in the battery module production.
