Problems solved by technology

[0002] The energy storage systems currently on the market usually use batteries for energy storage. These energy storage systems using battery energy storage have a slow discharge speed of the battery itself. Under a certain battery volume requirement, the load power of the energy storage system is large or the load power is instantaneous. When fluctuating, the battery energy storage system cannot meet the power requirements of the load, resulting in the load not working properly

Abstract

The invention discloses an energy storage system. The energy storage system comprises a charging unit, at least one energy storage unit, at least one inversion unit and a control unit, wherein the charging unit is used for charging the energy storage unit, the energy storage unit adopts a supercapacitor to store energy, the control unit is used for acquiring the stored electric quantity of the plurality of energy storage units and switching off the charging unit when the stored electric quantity of the energy storage unit reaches a set threshold, and the control unit switches off the charging unit when the inversion unit is still working. With the technical scheme disclosed by the invention, the transient output power of the energy storage system is improved.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to an energy storage system. Background technique [0002] The energy storage systems currently on the market usually use batteries for energy storage. These energy storage systems using battery energy storage have a slow discharge speed of the battery itself. Under a certain battery volume requirement, the load power of the energy storage system is large or the load power is instantaneous. When fluctuating, the battery energy storage system cannot meet the power requirements of the load, resulting in the load not working properly. Contents of the invention [0003] The main purpose of the present invention is to provide an energy storage system aimed at increasing the instantaneous output power of the energy storage system. [0004] In order to achieve the above object, the present invention proposes an energy storage system, including a charging unit, at least one energy...
