Recently, the core component stack in the third-generation all-vanadium redox flow battery energy storage system of Beijing Puneng Century Technology Co., Ltd. ("Beijing Puneng") successfully passed the tests stipulated in the UL 1973:2018 standard and obtained the CSA (Canadian Standards Association) ANSI/CAN/UL 1973 certification issued according to the standard .
UL 1973 is the safety standard for energy storage battery systems in North America . Battery cells, battery modules and battery systems, etc. Due to the authority, comprehensiveness and maturity of the UL 1973 standard, it is currently an internationally recognized and widely accepted battery safety standard, and it is also an important basis for related products to enter regional markets such as North America, Australia and South America. As an authoritative certification body, CSA has rich experience in standard setting, certification and commercial testing. The company has a history of more than 100 years in North America, and its logo is widely used on various products around the world.
Beijing Pu Neng's third-generation product ( VRB ESS Gen3 ) stack has passed a series of strict, complex and long-term tests of UL 1973:2018 , including material resistance test, vibration test, high temperature test, drop test and in-product test After 90 days of charging and discharging , the short-circuit test and many other safety tests can only be carried out by qualified third-party testing institutions. The third-generation stack certified this time has a rated power of 60 kW and a maximum power of 75 kW for long-term operation.
"The stacks in the third-generation energy storage products of Beijing Puneng can successfully pass the test and obtain the CSA certificate, which shows that the safety of Beijing Puneng's latest generation core stack products has reached international standards in terms of design, operation and manufacturing. It is an important basis for ensuring the intrinsic safety of vanadium flow battery energy storage products, and it is also the basis for us to expand domestic and foreign markets with third -generation energy storage products.” Dr. Huang Mianyan, President of Beijing Puneng said, "At the same time, through close communication and cooperation with the CSA team, Beijing Puneng has a deeper understanding of the UL1973 standard, which provides us with the design and manufacture, quality protection, and safe operation of subsequent products. clearer guidance."
Ms. Ge Yanqing, Vice President of CSA Group China, said, " CSA Group congratulates Beijing Puneng's third -generation stack products for obtaining the ANSI/CAN/UL 1973 certification. Puneng's products have been certified, marking the development of its all-vanadium flow technology. The core stack has excellent performance in terms of safety. We hope that Beijing Pudong can obtain the certification of its products from authoritative organizations like CSA , so that domestic and foreign customers can choose its all-vanadium flow energy storage products with more confidence.”
About Beijing Pu Neng
Pu Neng is a fast-growing global leader in energy storage technology innovation, focusing on the development of green, sustainable, long-life and intrinsically safe energy storage systems based on all-vanadium redox flow battery energy storage system (VRB-ESS®) . able solution. At present, PuNeng has installed and put into operation more than 70 projects in 12 countries and regions around the world. The cumulative safe and stable operation time is close to 1 million hours, and the total capacity is close to 70MWh . The total capacity of the projects in the development stage reaches 3GWh .
As a technology leader in the field of all-vanadium redox flow batteries, Poneng differentiates itself from other manufacturers with its unique low-cost ion exchange membrane, long-life electrolyte formulation and innovative stack design. The VRB-ESS® , patented by Pu Neng, is based on the redox reaction of metallic vanadium to store energy in the electrolyte. Since this is a process that can be nearly infinitely cycled, VRB-ESS® is safe, reliable, and almost 100% recyclable of the electrolyte. Compared with battery systems such as lead-acid and lithium batteries, the green energy storage solution of VRB-ESS® greatly improves the economic benefits of recycling, and is environmentally friendly throughout the process, which has huge advantages.
