SOC correcting method for Energy Storage System and SOC correcting system thereof

摘要

The present invention SOC and SOC correction system using the same calibration method of energy storage devices , A method for correcting the SOC of the energy storage system, generation ESS cluster by grouping a plurality of energy storage for generating the ESS cluster step; Cumulative collects information for each of the SOC of the energy storage devices contained in the cluster and the ESS, SOC calculation step of calculating the average SOC correction average value for a plurality of energy storage devices in the stacked SOC information based ESS cluster; And a SOC compensation method of the energy storage device, comprising: an SOC calculation step of calculating the actual value of SOC real value for each of the energy storage device based on the SOC correction average value, this one according to the present invention to solve the problems by stochastic according to piecemeal compensation SOC for the energy storage device by applying the correction value for the ESS SOC cluster grouping of a plurality of energy storage devices for correcting the SOC in the SOC of each of the energy storage device error is to be able to further reduce. ;
