Abstract

An apparatus includes an apparatus body and a battery pack removable from the apparatus body. Each of the apparatus body and the battery pack includes a memory unit configured to store a use permission flag written after authentications for a pair of the apparatus body and the battery pack through near field communication with a portable terminal, and a control unit configured to permit energization when the use permission flag of the memory unit is ON.

Claims

1. An apparatus comprising:

an apparatus body; and

a battery pack removable from the apparatus body, wherein each of the apparatus body and the battery pack includes

a memory unit configured to store a use permission flag written after authentications for a pair of the apparatus body and the battery pack through near field communication with a portable terminal; and

a control unit configured to permit energization then the use permission flag of the memory unit is ON.

2. The apparatus as claimed in claim 1, wherein the battery pack includes a checking unit configured to check battery status and the control unit is configured to permit energization when the battery status is normal.

3. The apparatus as claimed in claim 1, wherein each of the apparatus body and the battery pack includes an RFID chip configured to communicate with the portable terminal through the near field communication.

4. The apparatus as claimed in claim 1, wherein the battery pack includes an RFID chip configured to communicate with the portable terminal, and the use permission flag of the memory unit of the apparatus body is written through the near field communication between the battery pack and the apparatus body.

5. The apparatus as claimed in claim 1, wherein the control unit includes a determining unit configured to determine an elapsed time between a last usage and a present usage, and when the elapsed time between the last usage and the present usage is less than a predetermined length of time, the control unit permits energization even if the use permission flag of the memory unit is not ON.

6. The apparatus as claimed in claim 1, wherein the apparatus is an electric power tool, and the apparatus body is a tool body.

7. An apparatus authentication management system comprising:

an apparatus body;

a battery pack removable from the apparatus body; and

a portable terminal, wherein

each of the apparatus body and the battery pack includes

a memory unit configured to store a use permission flag written after authentications for a pair of the apparatus body and the battery pack through near field communication with the portable terminal; and

a control unit configured to permit energization when the use permission flag of the memory unit is ON.

9. The apparatus authentication management system as claimed in claim 7, wherein the battery pack includes a checking unit configured to check battery status and the control unit is configured to permit energization when the battery status is normal.

10. The apparatus authentication management system as claimed in claim 7, wherein each of the apparatus body and the battery pack includes an RFID chip configured to communicate with the portable terminal through the near field communication.

11. The apparatus authentication management system as claimed in claim 7, wherein the battery pack includes an RFID chip configured to communicate with the portable terminal, and the use permission flag of the memory unit of the apparatus body is written through the near field communication between the battery pack and the apparatus body,

12. The apparatus authentication management system as claimed in claim 7, wherein the control unit includes a determining unit configured to determine an elapsed time between a last usage and a present usage, and when the elapsed time between the last usage and the present usage is less than a predetermined length of time the control unit permits energization even if the use permission flag of the memory unit is not ON.

13. The apparatus authentication management system as claimed in claim 7, wherein the apparatus is an electric power tool, and the apparatus body is a tool body.

8. An apparatus authentication method in an apparatus authentication system, the apparatus authentication system comprising an apparatus body, a battery pack removable from the apparatus body, and

a portable terminal, the apparatus authentication method comprising:

a storing step of storing a use permission flag in a memory unit written after authentications for a pair of the apparatus body and the battery pack through near field communication with the portable terminal; and

a permitting step of permitting energization when the use permission flag of the memory unit is ON.
