Abstract

A charge management device includes a communication unit that communicates with a terminal device of an operator who delivers a charger for charging a vehicle of a user to a location desired by the user and collects the charger, and a control unit that transmits a collection instruction that instructs collection of the charger to the terminal device via the communication unit based on charging information that indicates a state of charge to the vehicle from the charger.

Claims (12)

1 . A charge management device comprising:

a communication unit that communicates with a terminal device of an operator who

delivers a charger to a location designated by a user, the charger being used to charge a vehicle of the user, and

collects the charger; and

a control unit configured to

transmit a collection instruction to the terminal device, via the communication unit, the collection instruction instructing the operator to collect the charger based on charging information that indicates a state of charge to the vehicle from the charger;

acquire connection data indicating a connection state between the charger and the vehicle as the charging information,

determine whether the charger is connected to the vehicle based on the acquired connection data, wherein

the collection instruction that is transmitted is a preferential collection instruction when the control unit determines that the charger is not connected to the vehicle, the preferential collection instruction instructing the operator to collect the charger without waiting for completion of charging of the vehicle.

2 . The charge management device according to claim 1 , wherein the control unit acquires charging rate data that indicates a charging rate of the vehicle as the charging information, determines whether a charging rate indicated by the acquired charging rate data is equal to or higher than a charging threshold value, and transmits a normal collection instruction as the collection instruction when determination is made that the charging rate is equal to or higher than the charging threshold value.

3 . The charge management device according to claim 1 , wherein the control unit further acquires position data that indicates a position of the charger when determination is made that the charger is not connected to the vehicle, and further transmits the position data when a distance between a position indicated by the acquired position data and the location is equal to or greater than a distance threshold value.

4 . The charge management device according to claim 1 , wherein the control unit further acquires access data that indicates whether to enter the location when determination is made that the charger is not connected to the vehicle, determines whether to enter the location based on the acquired access data, and lowers priority of the collection of the charger when determination is made that entry is not possible.
