<p>Provided is a vehicle charging device (170) that uses a power source (101) outside of a vehicle (160) to charge a battery (115) installed in the vehicle (160). A charger (114) charges the battery (115). A voltage measurement unit (111) measures the input voltage corresponding to the input current in the charger (114). A current measurement unit (112) measures the input current (Ic) in the charger (114). A control unit (113) changes the input currents (Ic) of the charger (114) into a plurality of values, and controls the input current (Ic) when the input voltage (Vc) has changed, according to the corresponding relationship between the input currents (Ic), when each has been changed, and the measured input voltages (Vc).</p> |
