Huawei Digital Power's Groundbreaking BESS Safety System

Huawei Digital Power has made headlines recently with its remarkable achievement in the energy storage sector. The company, in collaboration with various leading industry partners, has successfully completed a rigorous technical evaluation conducted by the China Electricity Council. This evaluation put the Full-Lifecycle Quantitative Safety Assessment System for Battery Energy Storage Systems (BESS) on the map, as it received the highest appraisal possible.

This high-level recognition signals that Huawei's BESS safety system is not only effective within China but also on a global scale. The assessment committee, comprising experts such as Professor Ouyang Minggao from Tsinghua University and various industry leaders, unanimously agreed that the system represents a world-leading standard, effectively addressing critical safety gaps in BESS technology.

Innovative Safety Features

One of the key attributes of Huawei's system is its innovative risk classification model, which categorizes safety risks into three levels: A (unacceptable), B (to be mitigated), and C (acceptable). This classification allows for a more structured approach to risk management, with Level A signaling extremely high, uncontrolled risks that need immediate action. On the other hand, Levels B and C present pathways for continuous improvement and ensure that serious consequences, such as fires, can be effectively prevented.

The evaluation also identified several key technologies that enhance the safety of BESS:

1. High-Precision Safety Alert Technology: This sophisticated alert system enhances operational condition coverage and ensures a remarkable recovery rate of 95% or more when faults occur.
2. Safe Battery Pack Architecture: The design incorporates pressure positive oxygen blocking and directional smoke extraction, making the battery packs resistant to thermal runaway, even when multiple cells overheat simultaneously.
3. Smart Energy Storage Conversion Architecture: This unique architecture prevents current feedback during network overvoltages across all states of charge (SOC), ensuring a consistent energy output and stable recovery during network disturbances.
4. High-Temperature Insulation and Real-Time Detection Technologies: These innovations reduce the risk of ignition from insulation failures, ensuring robust operational security.

Real-World Applications

Huawei's assessment framework has already been employed in large-scale energy projects across China and the broader global community. Notable projects include the ZDI Grid-Forming Energy Storage Plant in Ngari Prefecture, China, energy storage plants in Uzbekistan, and a 100% renewable energy microgrid project in Saudi Arabia.

Expert Endorsements

Professor Ouyang Minggao highlighted that the methodology behind Huawei's quantitative safety assessment system is revolutionary, offering exceptional technological innovations that significantly elevate the safety standards in the BESS industry. The professor noted that the project not only brings substantial economic benefits but also paves the way for enhanced social application, marking it as a frontrunner on a worldwide scale.

Steven Zhou, President of the Smart PV and ESS Product Line at Huawei Digital Power, expressed optimism about the future. He believes that the coming years will be pivotal for photovoltaic, wind, and storage energy to become mainstream energy sources. Zhou emphasized the need for industry stakeholders and organizations to collaborate on three crucial goals: developing standards, sharing technology, and creating a cohesive ecosystem.

As Huawei Digital Power strives to promote scaled-up, standardized, and high-quality industry growth, it aims to accelerate the adoption of renewable energy solutions. The end goal is to bridge the energy gap globally, providing greener, stable, and cost-effective energy for all.

In conclusion, Huawei Digital Power's advancements in battery energy storage safety not only showcase technological ingenuity but also a commitment to building a sustainable energy future. This unique combination of innovation and practical application underlines the company's leadership role in the energy sector.
