An apparatus controls the charging of a storage battery of an electric vehicle to optimize charging while accommodating any electrical loads that may be imposed on the storage battery, such as an air-conditioning unit or an accessory. The load is energized by the battery charger before the storage battery starts being charged by the charger while the charger is being connected to the storage battery and also after the charging of the storage battery is finished and until the charger is de-energized. In such instances, therefore, the load is energized by the charger without allowing a charging current to flow to or a discharge current to flow from the storage battery. Even when the load on the storage battery is actuated before the electric vehicle is operated, the electric energy stored in the storage battery is prevented from being unduly consumed.
