Safety Management of Sustainable Reuse of Power Batteries White Paper 2025

This white paper, jointly released by Shanghai Weixiang Zhongyi New Energy Technology Co., Ltd., Shanghai Institute of Chemical Industry Testing Co., Ltd., and TÜV Rheinland, addresses the safety management of sustainable reuse of power batteries. It covers industry overview, global market status, policies, business and technology trends, transportation safety requirements, and European and North American standards for safety testing of reused, repurposed, and remanufactured batteries. The document introduces a three-level classification system for old, waste, and bad batteries to support graded transportation. It also discusses safety design for energy storage utilization of vehicle-grade power batteries, including battery safety, electrical safety, software security, fire safety, and carbon emission reduction. The white paper aims to provide technical guidance for safety management, inspection, utilization, and recycling of used power batteries, aligning with international standards such as EU Battery Regulation 2023/1542, IEC, EN, and UL standards. It emphasizes the need for unified definitions and standards in battery echelon utilization to bridge gaps between domestic and international frameworks.
