MW-class Energy Storage System
MW-class energy storage systems are used in industrial and commercial buildings for energy load shifting, cost saving as well as power backup when there is power failure.
The system is charged automatically during valley time when eletricity is very cheap and discharge at peak time and the user can save cost from the huge price difference. Also, the energy storage system supplies power during power failure.
MW-class Energy storage systems are usually containerized for the advantages of high capacity, high reliability, high flexibility and environmental adaptability, which has a wide application prospect in the power grid system. The lithium battery energy storage system is more mature than other energy storage batteries, and the upstream and downstream industry chain is complete, so there is more room for cost reduction; at the same time, in countries where clean energy is not effectively utilized, the power system is in the situation of tight power supply during peak periods, low utilization of transmission and distribution capacity, shortage of active and reactive reserves and low transmission efficiency. The user side is also putting higher demands on load-side power quality. All these problems have accelerated the rapid development of energy storage technology.
The MW-calss energy storage battery uses lithium iron phosphate power battery, which has the advantages of stable charge and discharge performance, long service life, clean and environmental protection, and can save energy to the maximum extent.
The storage medium of the energy storage system is lithium iron phosphate battery with high safety and high cycle life, which is modular and easy to install and maintain.
The battery PACK box is 1P16S, and the parameter is 51.2V/280Ah (14.336kwh). The series of 14 battery modules consist one cluster, and the energy is 51.2V*280Ah*14=200kWh and five clusters consist the system.
