Abstract

As global demand for electric vehicles (EVs) surges, the traditional internal combustion engine vehicle supply chain is undergoing significant structural adjustments. Batteries, being a core component of EV performance and a major cost factor in new energy vehicles, make advancements in battery technology crucial for industry growth. This study analyzes CATL’s quality management strategies within the battery supply chain, focusing on procurement, research and development, and partnerships with suppliers. By examining CATL’s strategies in increasing procurement volumes, boosting R&D investment, and collaborating with upstream and downstream suppliers, this study reveals how the company enhances production efficiency and quality control through innovation and management optimization. The study compares CATL with BYD, highlighting differences in supply chain management strategies and effectiveness. Research indicates that CATL has strengthened market competitiveness and addressed industry challenges by optimizing supply chain management, enhancing supplier collaborations, and increasing R&D investment. This study provides an effective quality management model for the battery industry and suggests future research directions.
