Abstract
A method and a device for calibrating an SOC at tail end of charging or discharging of an energy storage system are provided. An SOC and a voltage of a battery unit are acquired in real time during charging or discharging of the battery unit. Whether the battery unit meets an SOC calibration condition is determined by comparing the SOC of the battery unit with a pre-calibrated calibration SOC at the tail end of charging/discharge and comparing the voltage of the battery unit with a calibration voltage, so that the SOC of the battery unit is timely calibrated if the SOC calibration condition is met.
