Abstract
A vehicle charging apparatus includes: an electric generatorthat is driven by an internal combustion engineand outputs an adjustable alternating-current voltage; a rectifierthat converts the outputted alternating-current voltage to a direct-current voltage; an electric storage devicethat is charged with the converted direct-current voltage; and a voltage sensorthat measures an output voltage of the rectifier. The vehicle charging apparatus is provided with a control devicethat controls the electric generatorfor a charging voltage to be a target charging voltage calculated from the output voltage in order to suppress a charging current to be lower than a charging current upper limit value when the electric storage deviceis charged. It thus becomes possible to achieve efficiency higher than that of a charging apparatus in the related art while preventing deterioration or damage of the electric storage device.
