Draft National Standard "Technical Specification for Mobile Electrochemical Energy Storage Systems" for comments
Polaris Energy Storage Network was informed that on April 24, the national standard "Technical Specification for Mobile Electrochemical Energy Storage Systems" was consulted. This document specifies the classification and architecture of mobile electrochemical energy storage systems, basic requirements, electrical performance, testing and inspection, marking, storage, transport and documentation, as well as operation and maintenance requirements. This document applies to mobile electrochemical energy storage systems of 380V and above interface voltage levels, other interface types can be implemented with reference. The rated charging or discharging power range of mobile electrochemical energy storage systems is 30kW ~ 2000kW, and the rated power supply time is not less than 1 hour.
China Energy Storage Network: State Grid Ningxia Electric Power Co., Ltd. Zhongwei Power Supply Company provided data showing that as of May 26, Zhongwei grid has now been grid-connected energy storage power station 2, capacity 350MW/700MWh, has accumulated 81.978 million kWh of charging, discharge 68.355 million kWh, equivalent to 26,200 tons of standard coal generated, reduce 64,400 tons of carbon dioxide emissions.
