Abstract

A battery SOC estimating apparatus according to an embodiment of the present disclosure includes a charging and discharging unit configured to receive a control signal including C-rate information and charge and discharge a battery at a C-rate included in the control signal; a measuring unit configured to measure a voltage of the battery in a charging and discharging process of the battery; and a control unit configured to transmit the control signal to the charging and discharging unit, change the C-rate included in the control signal whenever the voltage value measured by the measuring unit reaches a preset threshold value, and estimate SOC of the battery based on the result of comparing the changed C-rate with a preset cutoff value.
