Abstract

A system for updating battery software includes a programmable battery unit that includes an internal access point. The programmable battery unit includes a battery control unit that controls the overall functionality of the programmable battery unit. A programmable storage medium may be included on the battery control unit. The storage medium has stored therein battery software operable to control certain features of the programmable battery unit. An input port may be connected with the battery control unit. An update device that includes a second storage medium having stored therein updated battery software for the programmable battery unit. A connector may be included for connecting the update device to the input port of the programmable battery unit. A software routine on the update device is operable to automatically transfer the updated battery software from the update device to the first storage medium of the programmable battery unit thereby reprogramming the programmable battery unit.

Claims

1. A system for updating battery software, comprising:

a programmable battery unit that includes an programming access point;

a battery control unit associated with said programmable battery unit;

a first storage medium associated with said battery control unit;

an input port associated with said battery control unit accessible via said access point;

an update device including a second storage medium having stored therein updated battery software for said programmable battery unit;

a connector for connecting said update device to said input port of said programmable battery unit; and

a software module operable to transmit said updated battery software from said update device to said first storage medium of said programmable battery unit.

2. The system of claim 1, wherein said access point is located on an outside surface of said programmable battery unit and comprises an aperture formed in said programmable battery unit.

3. The system of claim 1, wherein said access point includes a sliding door operable to expose an aperture when positioned in an open state and to cover said aperture when positioned in a closed state.

4. The system of claim 3, wherein said sliding door includes a base portion that fits within at least one track of said programmable battery unit, wherein said sliding door is operable to move back and forth within said track.

5. The system of claim 4, wherein said sliding door includes a grip that protrudes upwardly from said base section of said sliding door.

6. The system of claim 1, wherein said first storage medium comprises a non-volatile memory.

7. The system of claim 1, further comprising a computing device connected with said update device for transferring said updated battery software to said update device.

8. The system of claim 1, wherein said software module automatically transfers said updated battery software to said programmable battery unit when a connection is established between said update device and said programmable battery unit.

9. The system of claim 1, further comprising means for indicating when a valid connection between said update device and said programmable battery unit has been made and said update device.

10. The system of claim 1, further comprising means for indicating when said software routine has completed updating said programmable battery unit.

11. A method of updating software in rechargeable batteries for use with portable electronic devices, comprising the steps of:

providing an access point in a programmable battery unit;

connecting an update device with an input port exposed through said access point of said programmable battery unit;

transferring updated battery software from said update device to said programmable battery unit; and

storing said updated battery software in a storage medium of said programmable battery unit.

12. The method of claim 11, wherein said access point comprises a sliding door operable to be moved between an open state and a closed state.

13. The method of claim 11, further comprising the step of generating an update in progress indication while said updated battery software is being transferred to said programmable battery unit.

14. The method of claim 11, further comprising the step of generating an update complete indication after said updated battery software has been successfully transferred to said programmable battery unit.

15. The method of claim 11, further comprising the step of disconnecting said update device from said input port.

16. The method of claim 11, wherein said update device comprises a portable handheld unit.

17. A battery update system, comprising:

a programmable battery unit including a housing having an access point located on an outside surface of said housing;

means for connecting an update device with an input port of said programmable battery unit that is exposed by said access point;

means for transmitting updated battery software stored in said update device to said programmable battery unit; and

means for storing said updated battery software in said programmable battery unit.

18. The battery update system of claim 17, wherein said access point comprises an aperture, wherein said programmable battery unit may include a sliding door operable to be positioned between an open state and a closed state thereby exposing and closing said aperture.

19. The battery update system of claim 17, further including means for generating an indication that an update is in progress.

20. The battery update system of claim 19, further including means for generating an second indication that said update is complete.
