the power supply device includes an alternating-current power supply device and a direct-current power supply device;
the vehicle includes
an engine, and
a motor that receives the power supplied from the battery to generate traveling drive force;

the vehicle is able to support both alternating-current charging using alternating-current power from the alternating-current power supply device and direct-current rapid charging using direct-current power from the direct-current power supply device; and
when the power supply by the direct-current power supply device is requested from the vehicle, the control device
acquires a remaining amount of fuel for the engine from the vehicle,
outputs an instruction to urge the vehicle to perform the power supply by the alternating-current power supply device when the remaining amount of fuel is larger than a reference value, the instruction including information indicating a charging time shorter than a request charging time requested for the battery, and
sets at least one of a unit price for charging power or a unit price for fuel lower when a response to accept the instruction is received from the vehicle compared with when the instruction is not accepted.
