A charging control unit is used in a system which includes an engine, a generator, and a battery charged with power generated by the generator, the system providing suspension control for inhibiting the restart of an engine during the suspension state of the engine. A charging control device comprises: a charging-to-discharging ratio calculation unit for calculating the charging-to-discharging ratio that is a ratio of the absolute value of the integrated value for the current charging a battery, to the absolute value of the integrated value for discharging current from the battery after the battery is fully charged; a pre-charge execution unit for allowing suspension control, charging the battery with power generated by the generator, and pre-charging to thereby increase the average remaining capacity of the battery, the precharge execution unit shortening the precharge period when the calculated charging-to-discharging ratio is high; and a refresh charging execution unit for allowing the battery to be fully charged with refresh charging which charges the battery with the power generated by the generator without the suspension control after the pre-charge.
