摘要： A vehicle includes a vehicle battery; a vehicle sensor configured to detect a current, a voltage and a temperature of the vehicle battery; and an alternator configured to output a target voltage to the vehicle battery. A controller is configured to calculate state of charge (SOC) estimation based on the current, voltage and temperature of the vehicle battery, calculate an initial SOC based on a direct current internal resistance (DCIR) map and apply the initial SOC to the SOC estimation, when an open circuit voltage (OCV) is maintained in a predetermined range after engine-off, and adjust an available SOC range based on a difference between an actual battery charge current amount, to which the initial SOC is applied, and the calculated SOC estimation.
