Abstract

A plug-in energy storage system is presented. The system includes: a plurality of battery racks configured to store power; and a panel configured to control charging or discharging of the plurality of battery racks, in which each of the battery racks includes: a plurality of battery modules configured to store power; a control module connected to each of the battery modules and the panel to control charging or discharging of each of the battery modules according to a control signal received from the panel; the conversion module is connected to the control module so as to convert the waveform of the electric power into direct current or alternating current according to the control signal received from the control module; and a case configured to accommodate each of the battery modules, the conversion module, and the control module. In addition, the plurality of battery modules and the battery power management unit integrally constitute each of the battery racks.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to Korean Patent Application No. 10-2021-0000936 filed on January 5, 2021, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The present disclosure relates to a plug-in energy storage system. Background technique [0004] The power grid that supplies the electricity produced by the power plant does not perform the function of storing electricity. Recently, as the amount of generation of renewable energy increases, there is a need to develop an energy storage system configured to store electricity. An energy storage system can store electrical energy generated from renewable energy sources and provide the electrical energy to a power grid when needed. The energy storage system may operate by charging and discharging the battery. Each battery composed of a rechargeable secondary battery deteriorates when charging and discharging...
