Abstract:
1. A vehicle battery charging apparatus for outputting a charging current from a power supply to an inlet of a vehicle having an electric motor as a drive source, the vehicle battery charging apparatus comprising: a charging connector located between the power supply and the vehicle inlet, the charging connector comprising a charging current output terminal for outputting the charging current to the vehicle inlet and a proximity detection terminal for detecting a proximity of the charging connector to the vehicle inlet; a first resistor located between the power supply and the vehicle inlet; a voltage output portion located between the power supply and the vehicle inlet that outputs a DC voltage to cause a current to flow through the first resistor to the proximity detection terminal, wherein the voltage output portion comprises a DC power source that operates by converting alternating current supplied thereto; a detection means located between the power supply and the vehicle inlet that can detect a variation in the current flowing through the first resistor caused by fitting the charging connector to the vehicle inlet; and a control section located between the power supply and the vehicle inlet that detects the proximity of the charging connector to the vehicle inlet based on the variation in current flowing through the first resistor detected by the detection means, and enables the charging current output terminal to output a charging current when the proximity is detected.
