Quality management for battery production: A 4.1. Method for quality man agement in battery production quality management during production. This procedure can be format and process structure. Hence, by detecting deviations in control and feedback are facilitated. properties. Among the external requirements are quality
A tool for quality-oriented production planning in assembly of battery modules was developed by , defining critical product and process characteristics and deriving appropriate quality assurance systems using a measurement equipment catalogue.
Quality gates in battery production equipment are identified. Depending on process layout, x 100% inspection or randomly chosen samples. assurance is to be preferred where possible. As suggested in illustrated in Fig. 1. production chain has to be carefully evaluated. Some universal . In particular, these are interrelations of processes, added
Goal is the definition of standards for battery production regardless of cell format, production processes and technology. A well-structured procedure is suggested for early process stages and, additionally, offering the possibility for process control and feedback. Based on a definition of int ernal and external
Hence, a comprehensive quality management concept is proposed, using a modified quality gate system for the operation of cell production. This Fig. 2. Aggregation of information in quality gates for decoupling of process steps and facilitation of decision making in case of target deviations. Fig. 3.
A sug- gested link to perceived product quality and actual energy of the produced battery cell is introduced. By this methodology, transparency along the manufacturing chain can be increased, which can lead to a better understanding of impacts of process deviations on the energy and material consumption.
