Vehicle charge device and vehicle charge system

Abstract

A vehicle charge device and a vehicle charge system include: a power converter that is connected to an AC power supply outside the first vehicle and converts AC power input from the AC power supply into first DC power; a voltage converter that transforms an input DC voltage into a charging voltage of the first battery; a voltage conversion control unit that controls the voltage converter; and a DC input terminal connected to a DC power supply outside the first vehicle, in which the DC input terminal inputs a DC voltage of second DC power input from the DC power supply to the voltage converter, and in which the voltage converter transforms the DC voltage of at least one of the first DC power or the second DC power into the charging voltage of the first battery according to an instruction from the voltage conversion control unit.
