Abstract

An apparatus and method for determining the status of a stand-alone power source, which includes a communications port that attaches to the power source, a processor linked to the communications port to process the data and output device to view the data. Additionally, a charger can be incorporated as a dual function to better diagnosis the power source as well as a means for charging the power source.

8. A method for determining and managing the status of a stand-alone power source comprising:

emulating a power management system with a processor;

retrieving data from the power source through a communications port that attaches to a power source data port;

processing the data received from the power source data port; and

displaying the processed data.

9. The method as in claim 8, wherein the step of processing the data is accomplished with a processor.

10. The method as in claim 9, further comprising entering codes into the processor.

11. The method of claim 8, wherein the step of displaying the data utilizes a display.

12. The method of claim 8, wherein step of displaying the data utilizes a printer.

13. The method of claim 8, wherein the communications port is serial port.

14. The method of claim 8, wherein the communication port is a parallel port.

15. A diagnostic apparatus that determines specific information and the status of a stand-alone power source, comprising:

means for emulating a power management system;

means for retrieving data from a power source data port, the means for retrieving data is linked to the means for emulating;

means for processing the data received from the power source is linked to the means for emulating; and

means for displaying the processed data is linked to the means for emulating.

16. The apparatus as in claim 15, wherein the means for processing the data is a processor.

17. The apparatus as in claim 15, further comprising means for entering codes into the processor.

18. The apparatus of claim 15, wherein the means for displaying the data is a display.

19. The apparatus of claim 15, wherein the means for displaying the data is a printer.

20. The apparatus of claim 15, wherein the communication port is a serial port.

21. The apparatus of claim 15, wherein the communication port is a parallel port.

22. A diagnostic apparatus that determines specific information and the status of a stand-alone power source, comprising:
