lithium ion based energy storage system

Battery energy storage system can be used to save the fixed equipment investment of the grid system; Improve the utilization rate of power grid equipment and reduce the cost of use for end users. Energy storage systems can reduce the peak energy load of users at the distribution end, which will facilitate the utilization of grid equipment and meet the needs of end customers. The load factor of the grid is thus improved. Battery storage systems can act as a buffer between a variety of power sources and stable power demand, increasing the capacity and legal quality of unstable power sources such as wind and solar. It can also be used for the peak cutting and valley filling of general power grid distribution users, storing the electric energy of the valley price in the form of direct current in the battery matrix (reactor), and then output it to various electrical appliances and electricity consumption at the power frequency (50Hz) during the peak price period, which is equivalent to using the electric energy of the low price period in the high price period, and the difference is the income of the peak-valley difference energy storage and power saving. Energy storage system includes energy and material input and output, energy conversion and storage equipment. Energy storage system usually involves a variety of energy, a variety of equipment, a variety of substances, a variety of processes, is a complex energy system with time changes, need a number of indicators to describe its performance. The commonly used evaluation indexes include energy storage density, energy storage power, energy storage efficiency, energy storage price and environmental impact. The energy stored per unit volume (volumetric heat storage density) is high, that is, the system stores as much energy as possible. Some customers consult the price list of lithium energy storage system, today the author gives an example to introduce the price of lithium energy storage system.
