Core Viewpoint - Huawei Digital Power has successfully passed a rigorous technical assessment by the China Electricity Council for its Full-Lifecycle BESS Safety Quantitative Assessment System, achieving a globally leading level in addressing critical safety gaps in battery energy storage systems (BESS) both in China and worldwide [1][3]. Group 1: Assessment and Innovation - The assessment committee, which included experts from Tsinghua University and various power grid organizations, unanimously praised the innovative technology and practicality of the quantitative safety assessment system for BESS [2][3]. - The project establishes a universal model for assessing the likelihood of safety risks in BESS, aiming to quantify and scientifically classify these risks, thereby filling a technical gap in safety standards [3][4]. Group 2: Safety Risk Classification - The assessment system classifies BESS safety risks into three levels: A (unacceptable), B (to be limited), and C (acceptable), with specific failure probability requirements for each level [4]. - Level A indicates extremely high risks that are unmanageable, while Level B denotes high risks that require continuous optimization and innovation in product design. Level C signifies manageable risks that can effectively prevent severe consequences like fires [4]. Group 3: Key Safety Technologies - The project has developed four key safety technologies, including: 1. Highly accurate intelligent active safety warning technology, ensuring a recall rate of at least 95% [5]. 2. Oxygen blocking under positive pressure and targeted smoke exhaust architecture, resulting in a highly safe battery resistant to thermal runaway [6]. 3. Intelligent dual-level conversion architecture for string energy storage, preventing backflow during transient voltage spikes [7][8]. 4. Sustainable high-temperature insulation and real-time detection technologies to suppress the risk of arcing due to insulation failures [9]. Group 4: Application and Impact - The project results have been applied in large-scale projects in China and globally, including energy storage installations in Ngari, Uzbekistan, and a microgrid in Saudi Arabia [10]. - The methodology developed is the first of its kind in the industry, significantly enhancing the overall safety level of the BESS industry and providing substantial economic and social benefits [11]. Group 5: Future Outlook - The President of Huawei Digital Power emphasizes that the coming years will be critical for photovoltaic (PV), wind, and energy storage to become mainstream energy sources, advocating for collaboration among industry players to promote standard development, technology sharing, and ecosystem building [12].
