On April 1, the 14th Energy Storage International Conference & Expo (ESIE 2026) opened in Beijing. During the event, Shenzhen ZH Energy Storage Technology Co., Ltd. was among the companies presented with certifications by SGS. Its FStack series flow battery stacks were certified to both UL 1973 and IEC 62932-2-2. The certification covers the full FStack range (FStack-35, FStack-32, FStack-16, and FStack-10), corresponding to different stack configurations. It indicates alignment with international requirements in safety, reliability, and technical performance. During the ceremony, Dr. Wei Xie, Founder and Chief Scientist of ZH Energy, noted that the certification reflects the team’s continued focus on flow battery technology, as well as its approach to safety and product quality. The FStack series has been deployed in more than ten countries, with ongoing collaborations across different applications. The stacks are developed in-house, covering material selection, structural design, manufacturing, and testing. This integrated approach helps maintain consistency and quality across production. Each batch undergoes multiple rounds of performance and safety testing before delivery to support stable operation in practical use. #Stack #FlowBattery
