CHARGING CONTROL DEVICE AND CHARGING TIME CALCULATION METHOD

A charge control device that charges a battery (20) using power output from a charger (10), wherein detecting means, charge state (SOC) calculation means, chargeable power calculation means, charge power calculation means, and charge time calculation means are provided. The detecting means detects the voltage and current of the battery (20). The charge state (SOC) calculation means calculates the SOC of the battery (20) using the detected values of detecting means. The chargeable power calculation means uses the detected values to calculate the power with which to charge the battery (20). The charge power calculation means calculates the charge power to be supplied to the battery (20) from the charger. The charge time calculation means refers to a map indicative of a relationship of the charge time of the battery (20) with respect to the charge state and charge power when the chargeable power for charging is greater than the outputtable power, which represents the power that is available to be outputted from the charger, and calculates, on the basis of the charge state calculated by the charge state calculation means and the charge power calculated by the charge power calculation means, the remaining charge time for the battery until the charge state of the battery (20) reaches a predetermined charge state. When the chargeable power for charging is less than the outputtable power, the charge time calculation means calculates the remaining charge time by subtracting the time according to the charge state from the remaining charge time calculated using the map.
