Abstract

A prognostics-enabled power system includes a power source and a removably connected load. A sensor is connected to the power source and situated to identify at least one characteristic produced in response to the removably connected load on the power source. A programmable system is in communication with the sensor, the programmable system situated to calculate a value from the at least one characteristic, wherein the calculated value is indicative of a health status of the power source.

7. The prognostics-enabled power system of claim 1, further comprising a communication element in communication with the sensor, the communication element situated to communicate at least one of the characteristic, the calculated value and a health status of the power source.

8. The prognostics-enabled power system of claim 1, wherein the programmable system may be reconfigured programmatically by a user.

9. The prognostic-enabled power system of claim 1, wherein the programmable system further comprises a programmable measurement mode wherein the programmable system calculates a value from the at least one characteristic indicative of a health status of the sensor itself.

10. The prognostic-enabled power system of claim 1, wherein the programmable system calculates a confidence interval associated with the calculated value indicative of the health status of the power source.

11. A system for sensing at least one of a state of health or a remaining useful life of a power source, the system comprising:
