Claim 0:
1. An in-vehicle charging device for converting, in a charging circuit, electric power supplied from an external power source, and supplying the electric power to a battery and a battery temperature adjustment device in parallel, the in-vehicle charging device comprising:
a control device for controlling an output current of the charging circuit such that the output current approaches a total value of an allowable value of a charging current of the battery and a current consumption of the battery temperature adjustment device at each time point during execution of charging, when temperature adjustment of the battery by the battery temperature adjustment device and charging of the battery are simultaneously executed,
wherein the allowable value of the charging current of the battery and the current consumption of the battery temperature adjustment device are identified based on battery characteristic information of the battery and heater characteristic information of the battery temperature adjustment device, the battery characteristic information and the heater characteristic information being stored in advance, and
wherein the control device controls the output current of the charging circuit such that the output current is larger than the allowable value of the charging current of the battery at each time point during execution of charging and is equal to or less than the total value of the allowable value of the charging current of the battery and the current consumption of the battery temperature adjustment device at each time point during execution of charging.
