Abstract
The present invention relates to an apparatus and a method for estimating a state of a battery, and more particularly, an apparatus for estimating a state of a battery includes: a first SOC estimating unit estimating a first state of charging (SOC) of the battery based on open circuit voltage and a temperature of the battery; a first SOH estimating unit estimating a first state of health of the battery based on the first SOC and the current of the battery; and a second SOC estimating unit estimating a second SOC of the battery based on the first SOH, charging/discharging voltage, the temperature, and the current of the battery or estimating the second SOC of the battery based on the charging/discharging voltage, the temperature, and the current of the battery.
