Abstract

An auxiliary failsafe engine starting apparatus locates the batteries or other power storage devices with respect to the current carrying cable(s) to provide high conformability between extended and storage configurations, and includes a protective power control switching module. High conformability of an apparatus is defined herein as being configurable between a greatest extended configuration having a length (l_e) and a storage configuration having a length (l_s), wherein l_e ≧3 l_s. Preferred apparatus have conformability ratios of ≧3, ≧4, ≧5, ≧7.5, and ≧10. Preferred power sources provide an electrical potential of at least 6 volts, and a current of at least 40 amps. More preferable power sources provide sustainable currents of at least 100 amps, and even more preferable power sources provide sustainable currents of at least 250 amps. Preferred cables are relatively long, measuring up to 4 feet or more, total extended length.

Claims

1. An auxiliary engine starting apparatus comprising:

at least two connectors;

a power source providing an electrical potential of at least 6 volts across the at least two connectors and the capacity to provide at least 20 amps to a load bridging the at least two connectors;

the apparatus configurable between a first configuration in which the apparatus has a length l_e and a second configuration in which the apparatus has a length l_s, wherein l_e ≧

3 l_s, and the length of the apparatus is equal to the greatest distance between any two points on the apparatus.

2. The device of claim 1 wherein l_e ≧

X l_s where X is one of 3.5, 4, 5, 7.5 and 10.

3. The device of claim 1 wherein the power source comprises

at least one energy storage device including at least one of a battery, a capacitor, and an ultracapacitor;

and

a power control switching module designed to sense the polarity of a charged load bridging the two connectors and to allow current to flow through the load only when

the polarity of the load matches the polarity of the voltage across the at least two connectors,

and the load current can be provided by the power source without damaging the device or any component thereof.

4. The device of claim 3 wherein the power source comprises a battery box and the device further comprises at least two cables, each of the at least two connectors coupled to a cable, each cable and connector pair removably coupled to the battery box.

5. The device of claim 3 wherein the at least one energy storage device has a preferred operating capacity and can be recharged from a state at which it has 50% or less of the preferred operating capacity to a state in which it has at least 90% of the preferred operating capacity in less than 20 minutes.

6. The device of claim 5 wherein l_e ≧

X l_s where X is one of 3.5, 4, 5, 7.5 and 10.

7. The device of claim 5 wherein the power source is elongated and has a length at least B times its width or diameter where B is one of 8, 15, 25, 40 and 70.

8. The device of claim 7 wherein the power source has a first end and a second end and the distance between the first and the second end can be modified.

9. The device of claim 8 wherein the power source comprises a plurality of cells flexibly linked together.

10. The device of any of claim 9 wherein l_e ≧

X l_s where X is one of 3.5, 4, 5, 7.5 and 10.

11. The device of claim 5 wherein the power control switching module comprises a solenoid and control logic.

12. The device of claim 5 wherein the power source detaches from the at least two cables in configuring the device in the storage configuration.

13. The device of claim 5 wherein the cable is at least L inches in length wherein L is 8, 24, and 36.

14. The device of claim 5 wherein the cable is at least 18 inches in length, and the power source provides a current of at least A amps across the at least two connectors/clamps where A is one of 100, 250, 400 and 600.

15. The device of claim 5 wherein electrical potential provided by the power source across the at least two connectors is at least V volts where V is one of 12, 24, and 36.

16. The device of claim 5 wherein the power source comprises a battery box and the device further comprises at least two cables, each of the at least two connectors coupled to a cable, each cable and connector pair removably coupled to the battery box.

17. The device of claim 16 wherein the power control switching module comprises a solenoid and control logic.
