APPARATUS FOR CORRECTING STATE OF CHARGE OF LOW-VOLTAGE BATTERY IN VEHICLE AND METHOD FOR THE SAME

An apparatus for correcting a state of charge (SOC) of a low-voltage battery inside a vehicle and a method for the same are provided. The apparatus includes a storage storing a table having an SOC value corresponding to a charging voltage and a charging time of the low-voltage battery inside the vehicle, a voltage sensor to measure the charging voltage of the low-voltage battery, and a controller to measure the charging time of the low-voltage battery, determine, from the table, the SOC value corresponding to the measured charging time and the measured charging voltage, and correct the SOC value of the low-voltage battery, based on the determined SOC value.
