Provided is a vehicle charging device vehicle charging device (170) that charges a battery (115) installed in a vehicle (160) from a power source (101) which is outside the vehicle (160). The charger (114) is connected to the external power source (101), and uses a variable input current for charging the battery (115). A control unit (113): changes the input currents of the charger (114) into a plurality of values, and determines lower thresholds for the appropriate ranges of the input current and the input voltage, according to the corresponding relationship between the input currents, when each has been changed, and the input voltages measured by a voltage measurement unit (111); and controls the input current when the input voltage has changed, according to the corresponding relationship and the lower thresholds, after charging has started. |
