Abstract

The present invention relates to an individual discharge system and method of a battery rack, and more particularly, to an individual discharge system and method of a battery rack capable of individually discharging a battery rack without depending on an external load.

Description

technical field [0001] The present invention relates to an individual discharge system and method of a battery rack, and more particularly, to an individual discharge system and method of a battery rack capable of individually discharging a battery rack without relying on an external load. Background technique [0002] With environmental damage and resource depletion increasing as serious problems, interest in energy storage systems (ESS) that store energy and efficiently utilize the stored energy is increasing. An energy storage device (ESS) configures a battery module by connecting a plurality of battery cells in series or parallel for maintaining driving voltage and efficient energy output, and includes a plurality of battery racks configured by connecting a plurality of battery modules in series or parallel . [0003] Generally, an energy storage device (ESS) is a passive system in which power is discharged by a power conditioning system during the daytime when power de...
