Modeling, analysis and improvement of production throughput and energy consumption in Li-ion battery manufacturing lines
通过结构建模和聚合技术，分析并改进锂离子电池生产线的产量和能耗，识别瓶颈并缓解，实现产量提升和能耗降低。
The rapid growth in demands of Li-ion batteries (LIBs) has prompted manufacturing companies to improve productivity continuously. In addition, to meet with carbon peak and carbon neutral strategies, increasing efforts are contributed to energy savings during production. This paper presents a case study involving modelling, analysis, and improvement of an LIB cell production line, from both productivity and energy saving perspectives. Through structural modelling of the line, a serial production line model with exponential machine reliability is developed. By using aggregation techniques, the system production throughput and energy consumption are evaluated and analysed. Upon this, continuous improvement efforts through bottleneck identification and mitigation are devoted to the system, leading to noticeable increments in line throughput and reduction in energy usage. Such a study provides an effective approach for analysing and improving LIB cell production lines in both productivity and energy metrics as well as other manufacturing systems.
