Original Abstract Submitted
The battery system includes a battery and a control device for estimating an SOC of the battery. SOC-OCV properties of the cell have a voltage-flat area. When the control device is activated for the first time, the control device estimates SOC of the cell based on SOC-OCV properties. At this time, when the voltage of the battery is in the voltage flat region (Vaâ¤VBâ¤Vb), S1 that is the intermediate value of the voltage flat region a is estimated to be SOC of the battery.
