Abstract

The invention belongs to the technical field of energy storage, and particularly relates to an energy storage system, which comprises a master controller, a battery unit, a charging unit, a battery management unit, an inverter and an operation interface, wherein the battery unit stores electric energy, and comprises a plurality of battery packs which are connected in parallel; the charging unit charges the battery unit, and comprises a plurality of chargers which are connected with the battery packs in a one-to-one correspondence to charge single battery packs respectively; the battery management unit performs charging management on the battery unit; the inverter converts the direct current of the battery unit into alternating current; the operation interface displays and operates each parameter state of the energy storage system; in a valley period or other periods when the electric energy is required to be stored, the charging unit charges the battery unit by using alternating current commercial power; and in a peak period or other periods when the electric energy is required to be supplemented, the inverter converts the direct current of the battery unit into the alternating current for a load. By the energy storage system, a user can rationally utilize electric energy resources, and peak shaving and valley filling functions in a power grid are realized.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to an energy storage system. Background technique [0002] With the sustained and rapid development of the national economy and the continuous improvement of people's living standards, the demand for electricity is increasing day by day. Although the country's power generation continues to increase, it cannot meet the needs of people's life and industrial and agricultural development. At the same time, there is also a contradiction in the actual power consumption: during the peak of power consumption during the day, the power supply is seriously insufficient, which restricts the development of industries such as industry, agriculture, commerce, and transportation; The period is the low point of electricity consumption, and the excess electricity can not be well utilized, resulting in a serious waste of resources. Based on the above contradictions in electricity c...
