Abstract

A cable is provided that may be used to provide an alternate source of voltage of a vehicular electrical system when the main battery of a vehicle is removed. The cable typically makes use of the battery or battery pack of a hand-held cordless power tool to provide the voltage. Also, the cable is typically electrically connected to the vehicle through the cigarette lighter outlet or through the j1962 connector of the vehicle. Also, a method of using the cable to preserve volatile memory data in a vehicle when the vehicle'"'"'s main battery is removed.

Claims

1. A cable, comprising:

a first adapter configured to be electrically connected to a cordless power tool battery;

a cord connected at a first end thereof to the first adapter; and

a second adapter connected to a second end of the cord and configured to be electrically connected to a vehicle.

2. The cable of claim 1, wherein the second adapter is configured to be electrically connected to a cigarette lighter outlet of the vehicle.

3. The cable of claim 1, wherein the second adapter is configured to be electrically connected to a j1962 connector of the vehicle.

4. The cable of claim 1, wherein the second adapter is configured to be electrically connected to a lead to a main battery of the vehicle.

5. The cable of claim 1, wherein the first adapter is configured to be electrically connected to at least one of an 18.8 V cordless power tool battery or a 14 V cordless power tool battery.

6. The cable of claim 1, further comprising:

a voltage regulator electrically connected to the first adapter and configured to regulate a voltage level that reaches the vehicle.

7. The cable of claim 1, further comprising:

a reverse polarity protector electrically connected to the first adapter.

8. The cable of claim 1, further comprising:

a charge indicator electrically connected to the first adapter.

9. The cable of claim 1, wherein the cord comprises a first wire and a second wire.

10. The cable of claim 9, wherein the first wire is a zip cord wire.

11. A method of saving volatile memory settings in a vehicle, the method comprising:

attaching a first adapter to a cordless power tool battery;

attaching a second adapter to a vehicle, wherein the second adapter is electrically connected to the first adapter; and

supplying voltage from the cordless power tool battery to the vehicle through the first adapter and the second adapter.

12. The method of claim 11, wherein the supplying step comprises:

electrically connecting the second adapter to a cigarette lighter outlet of the vehicle.

13. The method of claim 11, wherein the supplying step comprises:

electrically connecting the second adapter to a j1962 connector of the vehicle.

14. The method of claim 11, further comprising:

regulating a voltage level that reaches the vehicle with a voltage regulator electrically connected between the cordless power tool battery and the vehicle.

15. The method of claim 11, further comprising:

protecting against a reverse polarity surge using a reverse polarity protector electrically connected between the cordless power tool battery and the vehicle.

16. The method of claim 11, further comprising:

indicating whether the first adapter is charged using a charge indicator electrically connected between the cordless power tool battery and the vehicle.

17. A cable, comprising:

a first adapter configured to be electrically connected to a voltage source;

a cord connected at a first end thereof to the first adapter; and

a second adapter connected to a second end of the cord and configured to be electrically connected to a j1962 connector of a vehicle and to transfer power from the voltage source to the vehicle.

18. The cable of claim 17, further comprising:

a voltage regulator electrically connected to the first adapter and configured to regulate a voltage level that reaches the vehicle.

19. The cable of claim 17, further comprising:

a reverse polarity protector electrically connected to the first adapter.

20. A cable, comprising:

first connecting means for electrically connecting to a cordless power tool battery;

second connecting means for electrically connecting to a j1962 connector of a vehicle; and

third connecting means for connecting the first connecting means and the second connecting means.

21. The cable of claim 20, further comprising:

voltage regulating means for matching a first voltage from the cordless power tool battery and a second voltage level of an electrical system in the vehicle, wherein the voltage regulating means is electrically connected to the first connecting means.
