This chapter introduces relevant background information about the production of battery components and the assembly of battery systems (Sect. 2.1) as well as about how simulation can be used to imitate the behavior of production systems (Sect. 2.2).
They are a major component in battery packs — each battery pack has multiple cells, and each cell has multiple electrodes in it. While traceability is becoming more common for EV battery cell assembly, it''s not occurring at the electrode level.
The aim of this work was to demonstrate that a traceability system in battery cell production was used to determine the electrode balancing in multi-layer pouch cells. This approach can be used to detect production deviations and, consequently, establish quality gates.
