Abstract

A diagnostic system configured to test the performance of a vehicle component may include a processor configured to process test information from the vehicle component and control the vehicle component to be tested. The system may also include a memory configured to store the test information of the vehicle component and software that operates the vehicle component and a capacitive element configured to supply power to perform the testing of the vehicle component, wherein the memory and the capacitive element are in communication with the processor.

Claims

1. A diagnostic tool configured to test a performance of a vehicle component, the diagnostic tool comprising:

a processor configured to process test information from the vehicle component and control the vehicle component to be tested;

a memory configured to store the test information of the vehicle component and software that operates the vehicle component; and

a capacitive element configured to supply power to perform the testing of the vehicle component, wherein the memory and the capacitive element are in communication with the processor.

2. The diagnostic tool of claim 1, wherein the vehicle component is a starter motor component and the processor is also configured to control the starter motor and process starter motor information.

3. The diagnostic tool of claim 1, wherein the vehicle component is an alternator and the processor is also configured to control the alternator and process alternator information.

4. The diagnostic tool of claim 1, further comprising a charging module that controls a timing and an amount of charge provided to the capacitive element.

5. The diagnostic tool of claim 4, wherein the charging module charges the capacitive element with a constant voltage potential and/or current.

6. The diagnostic tool of claim 4, wherein the charging module charges the capacitive element with a variable voltage potential and/or current.

7. The diagnostic tool of claim 4, wherein the charging module charges the capacitive element based at least in part on an amount of power required to perform the testing of the vehicle component.

8. The diagnostic tool of claim 1, further comprising an interface module configured to receive identification information of a component of the vehicle to be tested.

9. The diagnostic tool of claim 8, wherein the interface module is configured to receive the identification information from a barcode reader, a RFID reader or a point-of-sale (POS).

10. The diagnostic tool of claim 1, wherein the test information includes at least one of the following:

test specification, test values, test results, data, time, employee, location and weather condition.

11. The diagnostic tool of claim 1, wherein the capacitive element comprises a plurality of capacitive elements.

12. A method of testing a vehicle component, comprising the steps of:

receiving, via an input device, a selection of the vehicle component for testing;

identifying, via an interface module, information associated with the vehicle component; and

charging, via a charging module, a capacitive element based at least in part on information associated with the vehicle component in order to perform the testing of the vehicle component.

13. The method of claim 12, wherein identifying information associated with the vehicle component comprises identifying a power level at which the vehicle component should be tested at.

14. The method of claim 12, wherein charging the capacitive element comprises charging the capacitive element before performing the testing of the vehicle component.

15. The method of claim 12, wherein charging the capacitive element comprises charging the capacitive element during the testing of the vehicle component.

16. The method of claim 12, further comprising starting the testing of the vehicle component using the capacitive element.

17. The method of claim 12, further comprising coupling a power source to perform the testing of the vehicle component.

18. The method of claim 17, wherein the power source is coupled when an output voltage potential and/or current falls to a testing threshold power level.

19. The method of claim 12, further comprising charging the capacitive element after completion of the testing of the vehicle component.

20. A diagnostic tool for testing a performance of a vehicle component, comprising:

an electrical connection for coupling the diagnostic tool to an external power source;

a power supply circuitry for processing power received from the external power source;

a test and control circuitry for controlling the testing of the vehicle component; and

a capacitive element for receiving processed power from the power supply circuitry to power the testing of the vehicle component.
