Abstract

A mobile terminal having one or more of the following modes: a standby mode, talk mode, send/receive mode, and read/write mode, includes a cell array being capable of providing a cell array power and a backup battery being capable of providing battery power. The mobile terminal has a power management system that when the mobile terminal enters standby mode and/or read/write mode, has the ability to supply the mobile terminal with only cell array power. The power management system further has, when the mobile terminal enters talk mode and/or send/receive mode, the ability to supply the mobile terminal with battery power and/or cell array power. In both events, the power management system has the ability to send any excess cell array power to recharge the battery.

Claims

1. A power management system for a mobile phone having as a primary power source a cell array and having as a backup power source a battery, the power management system comprising:

a first switch positioned to control power to and/or from the cell array; and

a second switch positioned to control power to and/or from the battery supply,

wherein in response to a power requirement from the mobile phone being equal to and/or less than an cell array power provided by the cell array, said first switch and said second switch being set to supply the mobile phone with only said cell array power, and

wherein in response to said power requirement from the mobile phone being greater than said cell array power but less than a combined power provided from the cell array and the battery, said first switch and said second switch being set to supply the mobile phone with said cell array power and battery power provided by the battery.

2. The system of claim 1, wherein the battery is a rechargeable battery.

3. The system of claim 2, wherein in response to said power requirement from the mobile phone being greater than said combined power provided from the cell array and the battery, said first switch and said second switch being set to supply the rechargeable battery with said cell array power.

4. The system of claim 2, wherein said power management system further includes a third switch, and when said mobile phone is attached to an external charger capable of providing charger power, said third switch being set to supply said mobile phone with said charger power.

5. The system of claim 4, wherein said second switch and said third switch being set to supply said rechargeable battery with said charger power.

6. The system of claim 4, wherein said first switch and said third switch being set to supply said cell array with said charger power.

7. A mobile terminal having one or more of the following modes:

a standby mode, talk mode, send/receive mode, and read/write mode, said mobile terminal further comprising;

a cell array being capable of providing a cell array power;

a backup battery being capable of providing battery power; and

a power management system including;

when said mobile terminal enters standby mode and/or read/write mode, means to supply said mobile terminal with only said cell array power, and

when said mobile terminal enters talk mode and/or send/receive mode, means to supply said mobile terminal with said battery power and/or said cell array power.

8. The mobile terminal of claim 7, wherein the backup battery is a rechargeable battery.

9. The mobile terminal of claim 8, wherein when said mobile terminal enters standby mode and/or read/write mode, said power management system includes means to supply said rechargeable battery with any excess cell array power not being used by said mobile terminal.

10. The mobile terminal of claim 9, further comprising an external charger being capable of providing charger power and said power management system including, when said external charger is supplying charger power, means to supply said mobile terminal with said charger power and/or said rechargeable battery with said charger power.

11. A portable electronic device, having as a primary power source a cell array and having as a backup power source a battery, the portable electronic device further having a power management system comprising:

a first switch positioned to control power to and/or from the cell array; and

a second switch positioned to control power to and/or from the battery supply,

wherein in response to a power requirement from the portable electronic device being equal to and/or less than an cell array power provided by the cell array, said first switch and said second switch being set to supply the mobile phone only cell array power, and

wherein response to said power requirement from the portable electronic device being greater than said cell array power but less than a combined power provided from the cell array and the battery, said first switch and said second switch being set to supply the portable electronic device cell array power and battery power provided by the battery.

12. The device of claim 11, wherein the battery is a rechargeable battery.

13. The device of claim 12, wherein in response to said power requirement from the portable electronic device being greater than said combined power provided from the cell array and the battery, said first switch and said second switch being set to supply the rechargeable battery with said cell array power.

14. The device of claim 12, wherein said power management system further includes a third switch, and when said portable electronic device is attached to an external charger capable of providing charger power, said third switch being set to supply said portable electronic device with said charger power.

15. The device of claim 14, wherein said second switch and said third switch being set to supply said rechargeable battery with said charger power.

16. The device of claim 14, wherein said first switch and said third switch being set to supply said cell array with said charger power.
