Huawei's Comprehensive Safety Evaluation for BESS

Huawei Digital Power recently achieved a significant milestone by successfully passing a rigorous technical evaluation for its Battery Energy Storage Systems (BESS) safety evaluation system. This evaluation was conducted by the China Electricity Council and represents a collaborative effort with prominent industry partners.

The assessment committee, which included distinguished experts like Professor Ouyang Minggao from Tsinghua University and leaders from major electric power organizations, unanimously agreed that this evaluation system meets world-leading standards. It fills critical technical gaps concerning battery energy storage system safety both in China and globally.

Purpose and Structure of the Safety Evaluation System

Huawei's safety evaluation framework addresses the operational safety bottlenecks faced during mass implementation of BESS technologies. The system classifies safety risks into three categories: Level A (unacceptable), Level B (to be mitigated), and Level C (acceptable). This tiered classification helps in quantifying the risks associated with these systems.

• - Level A indicates extremely high risks that are uncontrollable, with a substantial likelihood of severe safety incidents.
• - Level B denotes high risks that necessitate continued optimization of product designs and the introduction of innovative technologies.
• - Level C signifies manageable risks where severe consequences, like fire outbreaks, can be effectively avoided.

The innovative design employs a universal model to scientifically classify and quantify safety risks, ensuring enhanced operational safety for BESS technology.

Key Technological Innovations

The success of Huawei's BESS safety system hinges on several cutting-edge technological advancements:
1. Intelligent Safety Alert Technology: A high-precision active safety alert system that operates on a hierarchical architecture to ensure an impressive recall rate of at least 95%.
2. Fire Safety Mitigation: An oxygen-blocking architecture with positive pressure evacuation effectively prevents battery flames and propagation even during thermal runaway incidents.
3. Energy Chain Conversion Architecture: This design guarantees that grid current is not reinjected during transient overvoltages, maintaining stable network energy output and safeguarding equipment.
4. High-Temperature Insulation and Real-Time Detection: Innovations in insulation technology significantly reduce risks associated with electrical short circuits and electrolyte leakage by ensuring comprehensive, real-time monitoring.

These advancements are already proving their worth in large-scale projects not just in China, including the ZDI energy storage station in Ngari Prefecture, but also in international sites such as Uzbekistan and Saudi Arabia’s Red Sea renewable energy microgrid project.

Industry Impact and Future Prospects

Professor Ouyang remarked that the quantitative safety assessment methodology created through this initiative is unprecedented in the industry and exhibits remarkable technological advancements. It plays a pivotal role in elevating the safety standards in the BESS sector, promising significant economic and social benefits as well as broad potential applications.

Steven Zhou, President of Huawei's Smart PV ESS Product Line, indicated that the next few years are crucial for the growth of photovoltaic, wind, and energy storage technologies. He emphasized the importance of collaboration across the industry, including standardization and technology sharing, aimed at creating a thriving ecosystem.

Huawei Digital Power is fully committed to fostering large-scale, standardized, and high-quality industry development, hoping to narrow the global energy gap while providing green, stable, and affordable energy solutions for all.

In conclusion, Huawei's advancements in BESS safety evaluation not only underscore its commitment to innovation but also highlight its potential to drive forward the future of energy storage and sustainability globally.
