A kind of energy storage system and its control method

Abstract

The invention discloses an energy storage system and a control method thereof. The energy storage system comprises an energy storage body structure (1) and a standby power supply (2), wherein the energy storage body structure (1) is used for monitoring the power state thereof and performing a charging or discharging operation under a condition that the power state does not meet a set state or being switched into a standby state under a condition that the power state meets the set state; and the standby power supply (2) is connected with the energy storage body structure (1) and used for providing a standby power supply for the energy storage body structure (1) after the energy storage body structure (1) is switched into the standby state so as to continue to monitor the power state. The scheme disclosed by the invention can overcome the defects such that self-starting cannot be realized, the self-discharging amount is great and the difficulty of state monitoring is high in the prior art, and can achieve the beneficial effects of self-starting, small self-discharging amount and low state monitoring difficulty.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to an energy storage system and a control method thereof, in particular to an energy storage system and a method for realizing automatic operation and standby intelligent switching thereof. Background technique [0002] When analyzing the energy storage process, some objects or space ranges drawn in order to determine the research object are called energy storage systems. It includes energy and material input and output, energy conversion and storage equipment. [0003] An existing energy storage system generally includes an energy storage battery, a BMS (Battery Management System, battery management system), and a charging and discharging controller. The normal startup of the system is manually powered on, and then runs normally. When the battery does not need to be charged or discharged, in order to prevent the energy storage battery from self-discharging too ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an energy storage system and its control method in view of the above-mentioned defects, so as to solve the problem in the prior art that the energy storage system needs to be manually operated after being powered on again after shutdown, and cannot realize self-starting. Power on again after shutting down can achieve the effect of self-starting
