Abstract: A battery charging control method includes receiving a destination input to a navigation device. When a vehicle starts, a switch is turned on to charge a battery. When a State Of Charge (SOC) of the battery becomes larger than a preconfigured value, the switch is turned off for a first time interval derived on the basis of an estimated destination arrival time derived from the navigation device. The switch is turned on again at a time point at which the first time interval has passed. The switch is turned on again to charge the battery for a second time interval.
