A charging device includes a battery charger, a resistance heater, and a cooler. The battery charger is connected to an external power source and supplies electric power to a battery. The resistance heater is connected to the battery charger and converts electric power from the battery charger into heat. The cooler cools the battery charger and the battery with a cooling medium by causing the cooling medium to flow from the battery charger to the battery. When the charging device charges the battery under an environment of a predetermined temperature or lower, the battery charger supplies the electric power to the resistance heater, and heat generated in the battery charger is transmitted to the battery via the cooling medium.
