摘要： 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.

摘要： Provided are battery SOC estimating apparatus and method. The battery SOC estimating apparatus according to the present invention includes a first SOC calculating unit which applies a predetermined parameter to calculate a first state of charge (SOC) of a battery; one or more second SOC calculating units which individually apply different parameters to calculate one or more second SOCs of the battery; and an optimal parameter extracting unit which confirms a second SOC which is the closest to an actual SOC of the battery from one or more second SOCs to extract a parameter which is applied to the second SOC which is the closest to the actual SOC as an optimal parameter, in which the first SOC calculating unit applies the optimal parameter to calculate a final SOC of the battery.
