Original Abstract Submitted
The battery system includes a battery and a control device for estimating an SOC of the battery. When SMR is not connected when the replacement of the battery is detected, SOC is estimated based on SOC-OCV property from the voltage of the unit cell when the battery ECU is activated. When SMR is connected, the SOC estimated from the voltage is corrected using an integrated value of current charged or discharged via SMR, and SOC is estimated.
