Industrial & Commercial Energy Storage Safety White Paper

This white paper, jointly issued by SIG New Energy and Intertek Tianxiang Group, addresses the critical safety challenges in commercial and industrial energy storage systems (C&I ESS) amid global energy transformation. It highlights the explosive growth driven by cost reduction, grid stability, and carbon neutrality goals, while emphasizing safety as a key barrier to adoption. The document reviews frequent explosion incidents in 2025, such as fires in Scotland, Essex, and California, and analyzes core hazards including battery thermal runaway, electrical risks, and design/operation difficulties. It critiques traditional centralized cabinet solutions and battery designs for their limitations in safety and reliability. The paper then presents SIG's comprehensive modular solution, covering cell design, battery pack protection, system architecture, and cloud platform integration, alongside critical safety and reliability tests at cell, module, and system levels. It concludes that safety standards, circular economy, and cross-field innovation are essential for sustainable industry growth.
