Abstract

A charge control device that charges a battery using a power output from a charger has a charge state (SOC) calculation unit for calculating the SOC of the battery using the voltage and current of the battery, a charger control unit that controls a charger that charges the battery, and a charge time calculation unit for calculating, on the basis of the SOC calculated by the SOC calculation unit, the remaining charge time of the battery till the SOC of the battery reaches a prescribed SOC. When the charge current falls below a current threshold, the charger control unit sends intermittent power commands to the charger based on the prescribed SOC, and the charge time calculation unit subtracts, from the charge time calculated when the charge current has fallen below the current threshold, predetermined time values based on the power commands.
