SE Training Manual: Lithium-Ion Battery Cell Design and Testing

The SE Training Manual provides a comprehensive guide to lithium-ion battery science and engineering philosophy, focusing on prismatic hard case power cell design for electric vehicles. It covers general principles, cell design and product roadmap, structural functional requirements, and development models. Detailed sections address insulation design between the cap plate and terminal, advanced functional requirements, and structural testing and reliability assessment methods. Testing protocols include salt spray, high and low temperature storage, temperature cycling, high temperature high humidity, and mechanical shock/vibration tests. The manual also outlines structural component processes, main supplier capabilities, and cell application in modules. It emphasizes safety, reliability, and performance optimization for EV applications, serving as a technical reference for engineers and designers in the new energy industry.
