The control unit 31 associates the received information regarding the amount of charge with the tourist ID and registers it in the charge management table 32A (step S108).

FIG. 8 is a conceptual diagram illustrating the contents registered in the charging management table 32A. In the charging management table 32A, a record is prepared for each tourist to whom the electric vehicle 2 is lent. Each record includes, for example, tourist ID, tourist name, lending period, total charging amount, charging fee (total), charging date and time, parking lot ID, device ID, unit price (price per unit charging), charging amount , and the charging fee are recorded. The charging date and time is, for example, the charging start date and time, but may include both the charging start date and time and the charging end date and time. In the example of FIG. 8, the unit price is constant regardless of the parking lot, but the unit price may be different for each parking lot.

Next, the control unit 31 of the management server 3 determines whether to execute payment processing (step S109). When the electric vehicle 2 lent to a tourist is returned and the operating unit 34 receives a payment instruction from the business operator, the control unit 31 determines to execute payment processing. If it is determined that the payment process is not to be executed (S109: NO), the control unit 31 returns the process to step S107.

If it is determined that the payment process is to be executed (S109: YES), the control unit 31 reads the record of the corresponding tourist from the charging management table 32A, and outputs the charging fee based on the read record (Step S110). The output charging fee is displayed on the display unit 35.

As described above, in this embodiment, the charging amount and charging fee are managed for each tourist to whom the electric vehicle 2 is lent. Tourists can be billed for charging fees during the period. Tourists can pay the charging fee all at once when returning the electric vehicle 2, so they feel less troubled.

In Embodiment 2, a mode will be described in which the location of a parking lot in a tourist area where the non-contact power supply device 1 is installed is guided.
Note that the overall configuration of the charging management system and the configurations of the non-contact power supply device 1, the electric vehicle 2, and the management server 3 are the same as those in Embodiment 1, so the description thereof will be omitted.

FIG. 9 is a flowchart illustrating the operation procedure of the charging management system according to the second embodiment. The control unit 31 of the management server 3 reads information on the location of the parking lot where the non-contact power supply device 1 is installed from the storage unit 32, and transmits the read information from the communication unit 33 (step S201). At this time, the control unit 31 may transmit the information to the in-vehicle unit 21 included in the specific electric vehicle 2, or may transmit the information to the plurality of in-vehicle units 21 simultaneously by broadcasting.

Furthermore, when the electric vehicle 2 is equipped with a navigation device and the destination information inputted into the navigation device is acquired through communication, the control unit 31 of the management server 3 selects the parking lot closest to the destination. The location may be specified and information on the location of the specified parking lot may be transmitted to the electric vehicle 2. Furthermore, the control unit 31 may store advertising information including tourist information in the storage unit 32 and transmit the advertising information to the in-vehicle unit 21 at an appropriate timing.

The in-vehicle unit 21 included in the electric vehicle 2 receives information transmitted from the management server 3 through the wide area wireless communication unit 215 (step S202). The control unit 211 outputs the information received by the wide area wireless communication unit 215 from the connection unit 213 to the display unit 24, and displays the output information on the display unit 24 (step S203).

As described above, in the second embodiment, since the management server 3 transmits information on the location of the parking lot where the non-contact power supply device 1 is installed to the electric vehicle 2, the remaining capacity of the battery 222 is low. In this case, the tourist driving the electric vehicle 2 can refer to the information provided by the management server 3 to move to the nearest parking lot and charge the battery 222.

Furthermore, the GPS receiving unit 216 included in the electric vehicle 2 receives a GPS signal transmitted from a GPS satellite (not shown), and measures the current position of the electric vehicle 2 based on the received GPS signal (step S302). GPS receiving section 216 outputs the current position of electric vehicle 2 to control section 211 .

The control unit 211 determines whether the value of the remaining capacity of the battery 222 output from the power receiving unit 22 is less than or equal to a preset value (step S303). If it is determined that it is not less than the set value (S303: NO), the control unit 211 returns the process to step S301.

If it is determined that the remaining capacity of the battery 222 is less than or equal to the set value (S303: YES), the control unit 211 transmits position information indicating the current position of the electric vehicle 2 from the wide area wireless communication unit 215 to the management server 3. (Step S304).

The control unit 31 of the management server 3 receives the position information of the electric vehicle 2 transmitted from the in-vehicle unit 21 through the communication unit 33 (step S305). The control unit 31 identifies the location of the parking lot closest to the electric vehicle 2 based on the received position information (step S306). Information on the location of the parking lot is stored in the storage unit 32, and includes latitude and longitude information indicating the location of the parking lot, or map information indicating the location of the parking lot within the tourist area.

The control unit 31 reads information on the identified parking lot location from the storage unit 32, and transmits the read parking lot location information from the communication unit 33 to the in-vehicle unit 21 (step S307).

The control unit 211 of the in-vehicle unit 21 receives the information on the location of the parking lot transmitted from the management server 3 through the wide area wireless communication unit 215 (step S308). The control unit 211 outputs the information on the location of the parking lot to the display unit 24, and causes the display unit 24 to display the information on the location of the parking lot (step S309).

As described above, in the third embodiment, since the management server 3 transmits information on the location of the nearest parking lot where the non-contact power supply device 1 is installed to the electric vehicle 2, the remaining capacity of the battery 222 is When the amount of electricity becomes low, the tourist driving the electric vehicle 2 can refer to the information provided by the management server 3 to move the electric vehicle to the nearest parking lot and charge the battery 222.

Each record includes, for example, tourist ID, tourist name, lending period, total charging amount, charging fee (total), charging date and time, parking lot ID, device ID, unit price (price per unit charging), charging amount , charging fee, parking time, and parking fee are recorded.

The management server 3 can acquire information such as tourist ID, charging date and time, parking lot ID, device ID, charging amount, parking time, etc. by communicating with the power transmission control unit 12 or the in-vehicle unit 21. . Note that the power transmission control unit 12 may be equipped with a known sensor such as an infrared sensor in order to detect whether the electric vehicle 2 is parked. Further, the power transmission control unit 12 (vehicle-mounted unit 21) may detect parking of the electric vehicle 2 based on communication with the vehicle-mounted unit 21 (power transmission control unit 12).

The control unit 31 of the management server 3 calculates the charging fee and parking fee based on the acquired information, and registers each piece of information including the calculated charging fee and parking fee in the charging management table 32B. The method of calculating the charging fee is the same as in Embodiment 1, and the control unit 31 can calculate the charging fee, for example, by multiplying the charging amount and the unit price (charge per unit charging amount). Further, the control unit 31 can calculate the parking fee by multiplying the parking time and the unit price (parking fee per unit time).

Note that the parking fee can be set as appropriate, and the fee may be different depending on the time slot, or may be a fixed amount regardless of the time. Further, instead of the configuration in which the parking time is registered in the charging management table 32B, a configuration in which the parking start time and the parking end time are registered in the charging management table 32B may be used. Furthermore, information regarding the amount of charge and charging fee, and information regarding parking time and parking fee may be recorded in separate tables.

The control unit 31 of the management server 3 executes a payment process when the electric vehicle 2 lent to a tourist is returned and a payment instruction from the business operator is received by the operation unit 34 . At this time, the control unit 31 may perform payment processing by reading the record of the corresponding tourist from the charging management table 32B and outputting the charging fee and parking fee based on the read record.

As described above, in this embodiment, the charging amount and parking time are managed for each tourist to whom the electric vehicle 2 is lent. Tourists can be billed for charging fees and parking fees during the period. Tourists can pay the charging fee and parking fee all at once when returning the electric vehicle 2, so they feel less troubled.
