when the reservation information obtained by the battery charger makes charge reservations with a plurality of battery chargers, the reservation in question is set to a lower priority than priorities of other reservations.
4. A reservation system, wherein:
the reservation system comprises a navigation device, a server and a battery charger;
the navigation device generates reservation information of a charge and sends the reservation information to the battery charger;
the server makes a schedule by using the reservation information and sends the schedule to the battery charger;
the battery charger performs charging according to the schedule;
further, the battery charger notifies an arrival time of a booked vehicle to the server;
the server makes again a schedule according to the arrival time of the booked vehicle; and
the server:
sets a higher priority in order reservation information is obtained;
changes the schedule to a schedule in which a charge start time appointed at a time of booking is set ahead if another booked vehicle is not in course of charging, when a booked vehicle arrives earlier than an appointed time; and
changes the schedule to a schedule in which a charge time reserved for a booked vehicle of a higher priority can be secured, when a booked vehicle arrives later than an appointed time.
5. A battery charger, comprising:
an information acquisition part, which acquires reservation information of a charge from a navigation device;
a scheduling part, which makes a schedule by using the reservation information;
a rescheduling part, which makes again a schedule according to an arrival time of a booked vehicle; and
a charging part, which performs charging of a predetermined booked vehicle according to the schedule made by the rescheduling part, wherein:
the scheduling part sets a higher priority in order reservation information is obtained; and
the rescheduling part:
changes the schedule to a schedule in which a charge start time appointed at a time of booking is set ahead if another booked vehicle is not in course of charging, when a booked vehicle arrives earlier than an appointed time; and
changes the schedule to a schedule in which a charge time reserved for a booked vehicle of a higher priority can be secured, when a booked vehicle arrives later than an appointed time.
6. A battery charger of claim 5 , further comprises:
a message generation part, which generates a message when a reserved charge time cannot be secured because a booked vehicle arrives later than an appointed time; and
a sending part, which sends the message to the navigation device of the booked vehicle.
7. A battery charger, comprising:
an information acquisition part, which acquires reservation information of a charge from a navigation device;
a scheduling part, which makes a schedule by using the reservation information;
a rescheduling part, which makes again a schedule according to an arrival time of a booked vehicle; and
a charging part, which performs charging of a predetermined booked vehicle according to the schedule made by the rescheduling part;
a receiving part, which periodically receives update information including an amount of charge required for attaining full charge from a booked vehicle; and
a calculation part, which calculates a charge time from the amount of charge; wherein:
when a newest charge time calculated from the amount of charge in the update information is longer than a reserved charge time, the rescheduling part changes the schedule to a schedule in which the newest charge time can be secured; and
when the newest charge time is shorter than the reserved charge time, the rescheduling part changes the schedule to a schedule in which charge start times of booked vehicles later than a reservation for the vehicle are set ahead.
8. A battery charger, comprising:
