中文摘要：	随着全球对环保和可持续发展的重视，电动汽车产业迎来了前所未有的发展机遇。特别是国内新能源行业竞争持续加剧，车企在控制成本的同时，加速产品迭代，不断缩短开发周期，对电动汽车的质量管理带来了巨大挑战，而电动汽车的核心部件之一——动力电池，其性能和质量直接关系到电动汽车的续航里程、安全性和市场竞争力。电池模组作为动力电池的核心部件，其质量和性能直接影响动力电池的整体性能和用户体验。然而，电池模组在生产和使用过程中，常常受到多种因素的影响，导致电池模组的质量参差不齐。因此，电池模组质量提升管理研究，对于提高电池模组的质量稳定性、延长使用寿命、降低生产成本以及提升产品的市场竞争力具有重要意义。 本研究以L公司动力电池模组作为研究对象，遵循六西格玛DMAIC的质 量管理方法，对该公司模组汇流排焊接过程中的关键质量问题进行质量改进。首先对研究目的、研究方法、研究思路进行阐述，回顾了质量管理和六西格玛管理的相关理论研究进展。然后介绍L公司动力电池模组生产的主要流程及动力电池模组汇流排焊接过程的主要问题，探讨了使用六西格玛进行汇流排质量改善的可行性和必要性。最后将六西格玛的DMAIC改进流程应用于动力电池模组焊接质量改进，解决了乘用车动力电池模组汇流排焊接过程中出现的焊接强度不足的质量问题，提高了相关技术和质量人员的专业能力，也提升了公司保证质量的能力和客户满意度，并从多个维度制定保障措施，确保六西格玛在L公司的顺利推广。 研究结果表明，结合六西格玛质量管理方法的优化方案能够有效解决动力电池模组质量问题。它不仅提供了科学的问题分析工具，更通过实验设计找到了最优工艺参数，最终通过控制体系实现了质量的稳定与持续。本研究不仅为L公司电池生产过程的质量提升提供了实践指导，也为其他动力电池企业在生产运营中应对质量挑战提供了理论支持和参考。
英文摘要：	With the global emphasis on environmental protection and sustainable development, the electric vehicle industry has witnessed unprecedented development opportunities. Particularly, the competition in the domestic new energy sector has been intensifying continuously. While automakers strive to control costs, they are also accelerating product iterations and shortening development cycles, which poses significant challenges to the quality management of electric vehicles. One of the core components of electric vehicles - the power battery - has its performance and quality directly related to the vehicle's range, safety, and market competitiveness. As a core component of the power battery, the quality and performance of battery modules directly affect the overall performance of the power battery and the user experience. However, during the production and use of battery modules, they are often influenced by various factors, leading to inconsistent quality. Therefore, research on the quality improvement management of battery modules is of great significance for enhancing the quality stability of battery modules, extending their service life, reducing production costs, and improving the market competitiveness of products. This thesis takes the battery modules of L Company as the research object and follows the Six Sigma DMAIC quality management method to improve the key quality issues in the welding process of the module busbars. Firstly, it elaborates on the research purpose, methods, and ideas, and reviews the relevant theoretical research progress in quality management and Six Sigma management. Then, it introduces the main production process of L Company's battery modules and the main problems in the welding process of the module busbars, and discusses the feasibility and necessity of using Six Sigma to improve the quality of the busbars. Finally, the DMAIC improvement process of Six Sigma is applied to the quality improvement of battery module welding, solving the quality problem of insufficient welding strength in the welding process of the busbars of passenger vehicle battery modules, enhancing the professional capabilities of relevant technical and quality personnel, and improving the company's quality assurance capabilities and customer satisfaction. It also formulates safeguard measures from multiple dimensions to ensure the smooth promotion of Six Sigma in L Company. The research results show that the optimization plan combined with the Six Sigma quality management method can effectively solve the quality problems of battery modules. It not only provides scientific problem analysis tools but also finds the optimal process parameters through experimental design, and ultimately achieves stable and continuous quality through the control system. This thesis not only provides practical guidance for the quality improvement of L Company's battery production process but also offers theoretical support and reference for other power battery enterprises to deal with quality challenges in their production and operation.
