Abstract

Systems and methods are provided for downloading battery data to a mobile communication device. A system for downloading battery data to a mobile communication device may include a mobile communication device and a data server. The mobile communication device may be configured to monitor a battery operating condition and to receive a battery profile, the battery profile including battery data for use by the mobile communication device to calculate battery status information. The data server may be used for storing battery data, the data server being configured to receive the battery operating condition from the mobile communication device and, based on the battery operating condition, send the battery profile to the mobile communication device.

Claims

1. A mobile communication device comprising:

a battery configured to power the mobile communication device;

a sensor device configured to monitor an operating condition of the battery; and

an operating system configured to;

wirelessly transmit a battery operating condition to a data server,

wirelessly receive, from the data server, a battery profile corresponding to the current battery operating condition,

measure, at said operating condition, a value relating to the battery, and

calculate battery status information from the measured value using the battery profile.

2. The mobile communication device of claim 1 wherein the battery status information is battery capacity.

3. The mobile communication device of claim 1 wherein the battery status information is usable battery capacity.

4. The mobile communication device of claim 1 wherein the battery status information is equivalent series resistance.

5. The mobile communication device of claim 1 wherein the operating system is configured to select a portion of the battery profile to be sent from the data server.

6. The mobile communication device of claim 1 wherein the operating system is configured to replace an existing battery profile with the battery profile received from the data server.

7. The mobile communication device of claim 1 wherein the operating system is configured to transmit the battery operating condition to the data server in response to a user request.

8. The mobile communication device of claim 1 wherein the operating system is configured to transmit the battery operating condition to the data server in response to a change in ambient temperature.

9. The mobile communication device of claim 1 wherein the operating system is configured to transmit the battery operating condition to the data server in response to a power-up of the communication device.

10. The mobile communication device of claim 1 wherein the operating system is configured to transmit the battery operating condition to the data server in response to a new charge cycle of the battery.

11. A data server for storing battery profiles, comprising:

battery identifiers, each identifying a different battery type;

battery operating conditions that that include operating characteristics for each battery type; and

battery profiles, each corresponding to one of the battery identifiers and one of the battery operating conditions, the battery profiles containing information used to calculate battery status information and replace an existing battery profile on a mobile communication device;

the data server being configured to wirelessly receive a current operating condition and a current battery identifier from the mobile communication device and to wirelessly transmit a battery profile to the mobile communication device corresponding to the current operating condition and the current battery identifier.

12. The data server of claim 11 wherein the battery status information is battery capacity.

13. The data server of claim 11 wherein the battery status information is usable battery capacity.

14. The data server of claim 11 wherein the battery status information is equivalent series resistance.

15. The data server of claim 11 wherein the data server is configured to store the current battery operating condition received from the mobile communication device.

16. The data server of claim 11 wherein the profiles include electrical current verses transmit power.

17. The data server of claim 11 wherein the profiles include battery capacity verses battery voltage.

18. The data server of claim 11 wherein the profiles include battery capacity compensation factor verses temperature.

19. The data server of claim 11 wherein the profiles include equivalent series resistance compensation factor verses temperature.

20. The data server of claim 11 wherein the current operating condition is state of charge.
