Abstract

A battery or battery pack for a portable radio telephone is provided with a machine readable identification on its exterior. An electrical device, such as a portable radio telephone main unit and/or battery charger, has a battery identifier for reading or sensing the identification. Based upon the identification read by the identifier, the electrical device can prevent or establish an operational electrical connection with the battery cells in the battery.

Claims

1. A portable electronic apparatus battery comprising:

a frame;

at least one rechargeable battery cell located inside the frame; and

means for identifying a predetermined characteristic of the battery by an apparatus which the battery is intended to be operably used with, the identifying means including a machine readable identification code on an exterior of the frame.

2. A battery as in

claim 1

wherein the identifying means comprises an indicator of a battery cell type of the rechargeable battery cell.

3. A battery as in

claim 2

wherein the indication of the battery cell type indicates battery cell material.

4. A battery as in

claim 1

wherein the machine readable identification code comprises a bar code.

5. A battery as in

claim 1

wherein the identifying means comprises a section of semi-conductive material on the exterior of the frame, the machine readable identification code comprising an electrical resistance value of the section of semi-conductive material.

6. A battery as in

claim 1

wherein the machine readable identification code comprises a digitally encoded series of conductive film segments.

7. A battery as in

claim 1

wherein the battery has a plurality of the battery cells, the frame is a portable radio telephone battery pack housing, and the machine readable identifier code is on an exterior surface of the battery pack housing.

8. A portable electronic apparatus battery pack comprising:

a housing;

at least two rechargeable battery cells located inside the housing; and

means for identifying the battery cells inside the housing by an electronic apparatus which the battery pack is intended to be operably used with, the identifying means including a machine readable identification code at an exterior of the housing.

9. A battery pack as in

claim 8

wherein the machine readable identification code is coded to indicate the material which the battery cells are made of.

10. A battery pack as in

claim 8

wherein the machine readable identification code comprises a bar code.

11. A battery pack as in

claim 8

wherein the identifying means comprises a section of semi-conductive material on the exterior of the frame, the machine readable identification code comprising an electrical resistance value of the section of semi-conductive material.

12. A battery pack as in

claim 8

wherein the machine readable identification code comprises a digitally encoded series of conductive film segments.

13. A combined apparatus having a battery and an electrical device, the combined apparatus comprising:

the battery having a frame, at least one rechargeable battery cell located inside the frame, electrical battery terminals connected to the battery cell and extending to an exterior of the battery, and an identification section located, at least partially, at the exterior of the battery, the identification section comprising a machine readable identification;

the electrical device being connected to the battery and having electrical contacts operably connected to the battery terminals, the electrical device comprising a battery identifier adapted to read the machine readable identification of the battery when the battery is connected to the electrical device.

14. A combined apparatus as in

claim 13

wherein the electrical device comprises a portable radio telephone main unit.

15. A combined apparatus as in

claim 13

wherein the electrical device comprises a battery charger with a pocket for receiving a portion of the battery frame.

16. A combined apparatus as in

claim 13

wherein the machine readable identification comprises a bar code and the battery identifier comprises a bar code reader.

17. A combined apparatus as in

claim 13

wherein the identification section at the exterior of the battery comprises a section of semi-conductive material and the battery identifier of the electrical device measures resistance across the section of semi-conductive material.

18. A combined apparatus as in

claim 13

wherein the identification section at the exterior of the battery comprises a series of conductive and non-conductive strip areas.

19. A method of identifying a rechargeable battery device, the method comprising steps of:

connecting the rechargeable battery device to an electrical device, the rechargeable battery device having a machine readable identification on an exterior thereof and the electrical device having a battery identifier adapted to read the machine readable identification when the battery device is operably connected to the electrical device; and

the battery identifier reading the machine readable identification and comparing the machine readable identification to an acceptable battery identification for the electrical device.

20. A method as in

claim 19

wherein the electrical device is a portable radio telephone main unit and the step of connecting connects the battery device to the portable radio telephone main unit to form a complete portable radio telephone.

21. A method as in

claim 20

further comprising connecting the complete portable radio telephone to a combined telephone holder and battery recharger, wherein the combined telephone holder and battery recharger has a second battery identifier.

22. A method as in

claim 21

wherein the second battery identifier reads the machine readable identification on the battery device when the complete telephone is connected to the combined telephone holder and battery recharger.

23. A method as in

claim 21

wherein circuitry in the complete telephone transmits a signal to the combined telephone holder and battery recharger corresponding to the battery device machine readable identifier.

24. A method as in

claim 19

wherein the electrical device is a battery recharger and the step of connecting connects the battery terminals of the battery device to electrical contacts of the battery recharger.

25. A method as in

claim 19

further comprising preventing operable electrical connection of the electrical device to battery cells in the battery device unless the machine readable identification corresponds to the acceptable battery identification.

26. A method as in

claim 19

wherein the electrical device has at least two acceptable battery identifications.

27. A method as in

claim 26

wherein the electrical device is adapted to switch between at least two different active modes of operation based upon which of the acceptable battery identifications are read by the battery identifier.

28. A method of preventing improper use of a portable radio telephone rechargeable battery with an electrical device, the method comprising steps of:

providing the battery with an identification on an exterior thereof;

providing the electrical device with means for sensing the identification;

connecting the battery to the electrical device, the sensing means thereby sensing the identification; and

the electrical device establishing an operable electrical connection with the battery only if the battery and electrical device are operationally configured and intended to be used with each other based upon the sensed identification and an acceptable identification recognizable by the electrical device.

29. A method of manufacturing portable radio telephones comprising:

providing at least two different types of radio telephone batteries, the two different types of batteries having different types of rechargeable battery cells, the two different types of batteries each having a housing with a connection section which have similar sizes and shapes;

connecting two different machine readable identifiers to exteriors of the two different types of batteries, respectively; and

connecting one of the batteries to a first portable radio telephone main unit and the other battery to a second portable radio telephone main unit.
