Abstract
A charge control device includes a charge state (SOC) calculation unit that calculates the SOC of a battery using the voltage and current of the battery. A chargeable power calculation unit calculates the power with which to charge the battery and a charge power calculation unit calculates the charge power to be supplied from the charger. A charge time calculation unit uses a map that correlates in part combinations of charge state values and charge power values to output charge time values is used by the charge state calculation unit when the chargeable power is greater than the outputtable power. When the chargeable power for charging is less than the outputtable power, the charge time calculation unit calculates the remaining charge time by using the map to reduce the remaining charge time determined from the map.
