Abstract

A charging system includes a power transfer device and a rapid charging battery. The power transfer device includes a first power transfer unit being compatible with a first charging standard specifying that the rapid charging battery is to be charged at a predetermined current value. The rapid charging battery includes a first charging unit being compatible with the first charging standard, and a second power transfer unit being compatible with a second charging standard specifying that power is to be transferred at a predetermined current value that is lower than the predetermined current value specified by the first charging standard.

First claim

What is claimed is:

1. A charging system comprising:
a power transfer device;
a rapid charging battery; and
a server for providing a charging service to users, wherein:
the power transfer device includes a first power transfer unit being compatible with a first charging standard specifying that the rapid charging battery is to be charged at a predetermined current value;
the rapid charging battery includes:
a first charging unit being compatible with the first charging standard; and
a second power transfer unit being compatible with a second charging standard specifying that power is to be transferred at a predetermined current value that is lower than the predetermined current value specified by the first charging standard; and

the server comprises:
a memory storage unit storing at least one of user information for identifying a user who is eligible to receive the charging service and an identity information of a rapid charging battery that is eligible to receive the charging service;
a communication unit communicatively connected to at least one of the power transfer device and the rapid charging battery; and
a controller, and

the controller is configured to execute:
a process a1 of acquiring predetermined information that is verifiable with the user information and the identity information stored in the memory storage unit from at least one of the power transfer device and the rapid charging battery that are included in the charging system;
a process a2 of determining whether or not it is permissible to provide the charging service based on the predetermined information that is acquired in the process a1; and
a process a3 of charging the rapid charging battery with the power transfer device according to the first charging standard if it is determined in the process a2 that it is permissible to provide the charging service.

2. The charging system according to claim 1 , wherein the current value specified by the first charging standard is higher than or equal to 5 C rate of the rapid charging battery.

3. The charging system according to claim 1 , wherein:
the first charging unit pre-stores a predetermined current value corresponding to charging performance of the rapid charging battery; and
a current value at which the rapid charging battery is charged from the power transfer device is determined based on the current value that is stored in the first charging unit.

4. The charging system according to claim 1 , configured to execute a process of communicating usage information between the power transfer device and the rapid charging battery when the rapid charging battery is charged from the power transfer device.

5. The charging system according to claim 4 , configured to execute billing to a user of the rapid charging battery based on the usage information.

6. The charging system according to claim 1 , further comprising:
a mobile terminal,
the mobile terminal including:
an internal battery supplying electric power to the mobile terminal; and
a second charging unit electrically connected to the rapid charging battery and being compatible with the second charging standard.

7. The charging system according to claim 6 , wherein the rapid charging battery is incorporated in a protective case for the mobile terminal.

8. The charging system according to claim 7 , wherein:
the second charging unit stores a predetermined current value corresponding to charging performance of the internal battery; and
a current value at which the internal battery is charged from the rapid charging battery is determined based on the current value that is stored in the second charging unit.

9. The charging system according to claim 6 , wherein the rapid charging battery is built into the mobile terminal.

10. The charging system according to claim 6 , configured to execute:
a first charging process of charging the rapid charging battery from the power transfer device at a current value specified by the first charging standard; and
a second charging process of, subsequent to the first charging process, charging the internal battery from the rapid charging battery at a current value specified by the second charging standard.

11. The charging system according to claim 6 , configured to execute a process of communicating usage information between the power transfer device and the mobile terminal when the first charging process is executed.

12. The charging system according to claim 11 , configured to execute a process of billing to a user of the mobile terminal based on the usage information.

13. The charging system according to claim 6 , wherein
the server further comprises:
a memory storage unit storing at least one of user information for identifying a user who is eligible to receive a service and an identity information of a mobile terminal or a rapid charging battery that is eligible to receive the service;
a communication unit communicatively connected to at least one of the power transfer device, the rapid charging battery, and the mobile terminal; and
a controller; and

the controller is configured to execute:
a process b1 of acquiring predetermined information that is verifiable with the user information and the identity information stored in the memory storage unit from at least one of the power transfer device, the rapid charging battery, and the mobile terminal that are included in the charging system;
a process b2 of determining whether or not it is permissible to provide the service based on the predetermined information that is acquired in the process b1; and
a process b3 of charging the rapid charging battery with the power transfer device according to the first charging standard if it is determined in the process b2 that it is permissible to provide the service.

14. The charging system according to claim 13 , wherein the server is configured to communicate usage information with at least one of the power transfer device and the mobile terminal when the first charging process is executed.

15. The charging system according to claim 14 , wherein the server is configured to execute a process of billing to a user of the mobile terminal based on the usage information.

16. The charging system according to claim 14 , configured to execute a process of billing to a user of the rapid charging battery based on the usage information.

17. A charging system comprising:
a power transfer device;
a mobile terminal; and
a server for providing a charging service to users, wherein:
the power transfer device includes a first power transfer unit being compatible with a first charging standard specifying that a rapid charging battery is to be charged at a predetermined current value;
the mobile terminal includes:
a rapid charging battery;
an internal battery supplying electric power to the mobile terminal;
a first charging unit being compatible with the first charging standard and configured to charge the rapid charging battery; and
a second charging unit being compatible with a second charging standard specifying that charging is to be performed at a predetermined current value that is lower than the predetermined current value specified by the first charging standard, the second charging unit charging the internal battery from the rapid charging battery; and

the server comprises:
a memory storage unit storing at least one of user information for identifying a user who is eligible to receive the charging service and an identity information of a rapid charging battery that is eligible to receive the charging service;
a communication unit commun
