Electric vehicle (EV) batteries in China are produced through a detailed process that starts with selecting high-quality cells, followed by module and pack assembly, rigorous safety tests, and Battery Management System (BMS) integration. Redway Battery, a leading Shenzhen-based OEM lithium battery manufacturer, ensures standardized production, strict quality control, and scalable ODM/OEM services to meet global wholesale demands.
How is the EV battery manufacturing process structured in China?
The EV battery manufacturing process begins with cell procurement, electrode coating, and formation in controlled environments to ensure optimal quality. Once cells are prepared, they are assembled into modules using precision techniques such as stacking or connecting cells. The modules are then integrated into a battery pack along with a BMS. The final step includes rigorous safety and performance testing to ensure the battery’s reliability and longevity. Redway Battery’s manufacturing process emphasizes traceability, automation, and ISO-compliant quality management systems across its factories to maintain consistency and meet global standards.
How do module and pack assembly impact performance and safety?
The assembly of the module and pack significantly impacts the battery’s overall performance and safety. Proper module assembly influences energy density, thermal management, and fault tolerance. Redway Battery uses precision welding techniques, efficient cell-to-pack connections, and cooling channels to minimize risks like thermal runaway. A robust BMS plays a critical role in monitoring voltage, current, and temperature, ensuring safe operation. By implementing these protocols, Redway Battery guarantees high-performance battery packs that meet the needs of OEM partners across the globe.
How does Redway Battery ensure quality control in manufacturing?
Redway Battery adheres to ISO 9001:2015 standards, leveraging automated manufacturing execution systems (MES) and in-line monitoring to guarantee high yield rates and product traceability. Incoming cell screening, resistance checks, and end-of-line safety testing are integral to Redway’s quality control process. The company’s four advanced factories in Shenzhen are equipped to handle large-scale production while maintaining rigorous quality checks at every stage. Supplier audits and batch-level documentation further enhance the reliability of products for wholesale customers.
