Abstract

A portable electronic device receives notification from a base station showing that the amount of energy or fuel remaining in a battery is low. The portable electronic device then has a display showing the remaining amount of energy or fuel in the battery is low in accordance with the notification. Location information is received by a location information receiving section, and is transmitted to the base station. The portable electronic device receives fuel supplying device information showing the location of a device able to supply fuel or give a charge of electricity to the battery from the base station. A supplying device provides the fuel or gives the charge of electricity in accordance with information transmitted from the portable electronic device, and transmits information showing the compensation owed to the base station.

Claims

1. A portable electronic device having a battery as a power source, comprising:

a display which displays that a remaining energy of the battery is small;

a position receiver which receives position information;

a transmitter which transmits position information received by the position receiver and information showing a portable electronic device model to a base station; and

a device information receiver which receives supplying device information showing a position of a supplying device able to supply fuel or give a charge of electricity to the battery from the base station.

2. A portable electronic device according to claim 1, wherein

the portable electronic device has a notification receiver which receives notification showing that the remaining amount of the battery is small from the base station, and

the display performs display in accordance with the notification received by the notification receiver.

3. A portable electronic device according to claim 2, wherein the notification received by the notification receiver has information showing a required fuel supplying amount or charging amount.

4. A portable electronic device according to claim 1, wherein

the portable electronic device transmits identification information for discriminating the portable electronic device and information showing a fuel supplying amount or a charging amount to a supplying device able to supply the fuel or give the charge of electricity to the battery.

5. A supplying device able to supply fuel or give a charge of electricity to a battery of a portable electronic device, comprising:

a mounting section which mounts the portable electronic device;

a receiving section which receives ID information for discriminating the portable electronic device from the portable electronic device;

a supplying section which supplies the fuel or giving the charge of electricity to the battery of the portable electronic device; and

a transmitting section which transmits information corresponding to compensation for the fuel supply or the charging performed by the supplying section to a base station.

6. A supplying device according to claim 5, wherein

the receiving section receives supplying information showing the supplying amount of the fuel or the charging amount from the portable electronic device;

and

the supplying section supplies the fuel or gives the charge of electricity to the battery of the portable electronic device in accordance with the supplying information.

7. A supplying device according to claim 5, wherein

the supplying device has a selecting section which selects a paying method of the compensation, and the transmitting section transmits no information corresponding to the compensation to the base station when the paying method using cash is selected by the selecting section.

8. A replenishing method for replenishing fuel to a portable electronic device, comprising the steps of:

transmitting position information relating to the position of the portable electronic device and device information showing a portable electronic device model from the portable electronic device to a base station;

transmitting information showing the position of a supplying device able to replenish the fuel from the base station to the portable electronic device in accordance with the position information and the device information when the base section receives the position information relating to the position of the portable electronic device;

transmitting identification information able to discriminate the portable electronic device from the portable electronic device to the supplying device; and

transmitting the identification information and information relating to compensation of the fuel supply from the supplying device to the base station after the supplying device supplies the fuel to the portable electronic device.

9. A portable electronic device having a battery as a power source, comprising:

a notifying section which performs predetermined notification when a remaining amount of the battery is smaller than a predetermined amount;

a position receiving section which receives position information;

a transmitting section which transmits the position information received by the position receiving section, and information showing a portable electronic device model to a base station; and

a device information receiving section for receiving supplying device information showing the position of a supplying device able to supply fuel or give a charge of electricity to the battery from the base station.
