Apparatus for controlling the currents supplied for battery charging and an electric load during charging of an electric vehicle battery

摘要

When the main battery of an electric vehicle is being charged and any one of an air-conditioner ON/OFF switch, a pre-air-conditioning preference ON/OFF switch, an external-input-controlled timer pre-air- conditioning preference ON/OFF switch, and an external-input-controlled pre-air-conditioning ON/OFF switch is turned on, a charging control device causes the maximum output current from the battery charger to be distributed between the battery and a motor-driven air conditioner or other electric load at a certain ratio on a real-time basis or at a start time established by a pre-air-conditioning timer or a timer in an air- conditioner controller. Therefore, the motor-driven air conditioner or other electric load can be operated and a charging current can be supplied to the battery at the same time even if the rated output capacity of the charger is relatively small. Consequently, the motor- driven air conditioner or other electric load can efficiently be operated while the battery is being charged.
