Huawei Digital Power Achieves a Milestone in BESS Safety Evaluation
In a commendable achievement for the renewable energy sector, Huawei Digital Power has successfully topped a rigorous technical evaluation conducted by the China Electricity Council. This assessment was designed to scrutinize the
Battery Energy Storage System (BESS) safety evaluation system, which is vital for ensuring the safety of battery storage systems throughout their lifecycle.
The evaluation committee, containing experts from various prestigious institutions such as Tsinghua University, China Southern Power Grid, and TÜV Rheinland, unanimously recognized that Huawei's innovative approach fills critical technological gaps in BESS safety both within China and on a global scale. This system is not just a theoretical framework but represents an actionable roadmap to enhance the safety and reliability of energy storage solutions.
Innovative Framework for Safety Assessment
The safety evaluation system proposed by Huawei categorizes BESS safety risks into three distinct levels:
A (unacceptable risk),
B (risk to be mitigated), and
C (acceptable risk). This structured classification allows for a clear understanding of potential hazards associated with battery storage systems:
- - Level A signifies extremely high risk, indicating a substantial probability of severe safety incidents.
- - Level B highlights elevated risks that necessitate ongoing improvements through design optimization and technological advancements.
- - Level C denotes manageable risks, suggesting that severe consequences, such as fires, can be effectively avoided.
This methodology serves as a pivotal advancement in addressing operational bottlenecks in large-scale BESS applications and seeks to create a universal risk evolution model.
Key Technologies Enhancing Safety
Huawei's system integrates four main safety technologies:
1.
High-Precision Smart Safety Alert Technology: This proactive measure enhances the coverage of fault detection algorithms, achieving a recall rate of over 95%, thereby significantly mitigating risks before they escalate.
2.
Oxygen Blocking Architecture: A newly developed battery pack structure provides a high degree of heat resistance and positive pressure, preventing thermal instability of battery cells—even in challenging conditions.
3.
Double-Level Conversion Architecture: This innovative design prevents voltage backflow during transient voltage spikes across the entire state of charge (SOC), ensuring stable power outputs and equipment safety.
4.
High-Temperature Insulation Technologies: Real-time monitoring capabilities drastically reduce risks associated with electrolyte leakage, further bolstering system reliability.
These technologies have already been implemented in numerous projects across China and globally, including renewable energy microgrid setups in Saudi Arabia and energy storage facilities in Uzbekistan.
Industry Impact and Future Outlook
Professor Ouyang Minggao from Tsinghua University emphasized that this methodology marks a significant first in the industry, with outstanding technological innovations that promise to uplift the safety level of the BESS segment. He noted that the project stems not only economic benefits but also opens expansive application prospects in the renewable energy arena.
Looking ahead, Steven Zhou, president of the Smart PV ESS Product Line at Huawei Digital Power, stated that the next few years are poised to be transformative for photovoltaic and wind energy systems alongside energy storage solutions.
Huawei Digital Power is committed to collaborating closely with industry partners to promote a wide-scale, standardized, and high-quality development of the sector, ultimately striving to bridge the global energy gap and deliver reliable, green energy for all. This collective effort underscores the importance of creating robust ecosystems built on shared technology standards.
In conclusion, this groundbreaking evaluation system by Huawei Digital Power not only sets a benchmark in safety practices but also showcases the potential of innovative technologies to drive the energy storage market forward strategically and sustainably.
