All-vanadium Liquid Flow Energy Storage System
The intelligent temperature control system installed in the energy storage product can meet the requirements of operation within the temperature range of -20℃ - 55℃, in areas with elevation below 2,000 m, and in severe environments such as deserts and polar regions. The system is of modular design, and the power unit of a single stack can be expanded to 500kW, meeting the demand for megawatt-class power storage systems by parallel connection of multiple stacks.
Product Introduction
Having the advantages of intrinsic safety and independent design of system power and capacity, the all-vanadium liquid flow energy storage system can be applied to scenarios of special demand, such as remote well sites, and can meet the long-term energy storage demand for more than 4 h. Therefore, it has significant technical advantages in the construction of zero-carbon well sites in oil fields. The whole product is of container type, facilitating management, and operation and maintenance. The system features low self-discharge performance and low capacity attenuation rate, and the comprehensive efficiency can reach over 70%.
