Electric vehicle charging management system using delivery-based connector attachment and detachment

A substitution system comprising:

• a vehicle comprising a vehicle battery and a charging port electrically coupled to the vehicle battery;
• a charge/discharge connector configured to be attached to the charging port in a detachable manner, the charge/discharge connector being configured to supply electric power from outside of the vehicle to the vehicle or supply electric power from the vehicle to outside of the vehicle;
• and
• a control device comprising at least one processor and at least one memory coupled to the at least one processor, wherein
• the at least one processor is configured to perform an operation comprising:
• when a delivery person is to deliver an item to a delivery destination, determining whether the vehicle is present at the delivery destination by comparing location information of the vehicle, acquired via a global positioning system, with location information of the delivery destination within a predetermined allowable range of error;
• and
• in a case where the processor determines that the vehicle is present at the delivery destination, acquiring a SOC of the vehicle battery via electronic communication with the vehicle and coupling condition information indicating whether the charge/discharge connector is coupled to the charging port via a coupling sensor configured to detect attachment of the charge/discharge connector to the charging port or detachment of the charge/discharge connector from the charging port, and determining whether to set attachment substitution or detachment substitution in accordance with the SOC and the coupling condition information by executing predetermined substitution determination logic,
• wherein, in the attachment substitution, the delivery person who visits the delivery destination to deliver the item attaches the charge/discharge connector to the charging port to start charging or discharging of the vehicle battery, and
• wherein, in the detachment substitution, the delivery person who visits the delivery destination to deliver the item detaches the charge/discharge connector from the charging port to stop charging or discharging of the vehicle battery.
