Abstract

Claims (43)

1. An electric starting system for an internal combustion engine, comprising:

a rechargeable battery including two voltage output terminals and an enable terminal, wherein the enable terminal of the rechargeable battery is positioned remote from the two voltage output terminals of the battery;

a battery receiver including a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and an enable terminal, wherein the enable terminal of the battery receiver is positioned remote from the two voltage output terminals of the battery receiver; and

a starter motor configured to start the internal combustion engine;

wherein the voltage output terminals of the lithium-ion battery and the battery receiver are configured to connect to complete a circuit between the rechargeable battery and the starter motor when the rechargeable battery is attached to the battery receptacle; and

wherein the enable terminal of the rechargeable battery must be connected with the enable terminal of the battery receiver for the rechargeable battery to receive an enable signal to allow the rechargeable battery to provide power to the starter motor to start the internal combustion engine.

2. The electric starting system of claim 1 , wherein if the enable terminal of the rechargeable battery is not connected to the enable terminal of the battery receiver, the rechargeable battery does not provide power to the starter motor.

3. The electric starting system of claim 1 , wherein the terminals of the rechargeable battery comprise female terminals and the terminals of the battery receiver comprise male terminals.

4. The electric starting system of claim 1 , wherein the rechargeable battery further includes a latch and the battery receptacle further includes a latching region; and

wherein the latch engages the latching region to secure the rechargeable battery to the battery receiver.

5. The electric starting system of claim 1 , wherein the rechargeable battery is configured to be selectively attached to and removed from the battery receiver without tools.

6. The electric starting system of claim 1 , wherein the rechargeable battery further includes a display for providing information to a user.

7. An electric starting system for an internal combustion engine, comprising:

a rechargeable battery including two voltage output terminals and an enable terminal, wherein the enable terminal of the rechargeable battery is positioned proximate to the two voltage output terminals of the battery;

a battery receiver including a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and an enable terminal, wherein the enable terminal of the battery receiver is positioned proximate to the two voltage output terminals of the battery receiver; and

a starter motor configured to start the internal combustion engine;

wherein the voltage output terminals of the lithium-ion battery and the battery receiver are configured to connect to complete a circuit between the rechargeable battery and the starter motor when the rechargeable battery is attached to the battery receptacle; and

wherein the enable terminal of the rechargeable battery must be connected with the enable terminal of the battery receiver for the rechargeable battery to receive an enable signal to allow the rechargeable battery to provide power to the starter motor to start the internal combustion engine.

8. The electric starting system of claim 7 , wherein the battery receptacle is defined at least in part by a wall; and

wherein the voltage output terminals and the enable terminal of the battery receiver extend outward from the wall and the enable terminal of the battery receiver extends to a distance less than the voltage output terminals of the battery receiver.

9. The electric starting system of claim 7 , wherein the voltage output terminals of the battery receiver are configured to connect to the voltage output terminals of the rechargeable battery before the enable terminal of the battery receiver connects to the enable terminal of the lithium-ion battery.

10. The electric starting system of claim 7 , wherein if the enable terminal of the rechargeable battery is not connected to the enable terminal of the battery receiver, the rechargeable battery does not provide power to the starter motor.

11. The electric starting system of claim 7 , wherein the terminals of the rechargeable battery comprise female terminals and the terminals of the battery receiver comprise male terminals.

12. The electric starting system of claim 7 , wherein the rechargeable battery further includes a latch and the battery receptacle further includes a latching region; and

wherein the latch engages the latching region to secure the rechargeable battery to the battery receiver.

13. The electric starting system of claim 7 , wherein the rechargeable battery is configured to be selectively attached to and removed from the battery receiver without tools.

14. The electric starting system of claim 7 , wherein the battery receptacle is defined at least in part by a floor including a wall that separates a lower portion of the floor from an upper portion of the floor;

wherein the rechargeable battery includes a bottom side including a wall that separates a lower portion of the bottom side from an upper portion of the bottom side; and

wherein the wall of the battery receptacle contacts the wall of the lithium-ion battery to limit the travel of the rechargeable battery relative to the battery receiver when attaching the rechargeable battery to the battery receiver.

15. The electric starting system of claim 14 , wherein the battery receiver further includes a plurality of guides that extend outward from the wall of the battery receptacle to a distance greater than that of the terminals of the battery receiver; and

wherein the rechargeable battery further includes a plurality of apertures formed in the bottom side;

wherein each aperture is sized and positioned to receive one of the guides of the battery receiver to guide the lithium-ion battery into the battery receptacle.

16. The electric starting system of claim 14 , wherein the voltage output terminals and the enable terminal of the battery receiver extend outward from the wall of the battery receptacle and the enable terminal of the battery receiver extends to a distance less than the voltage output terminals of the battery receiver.

17. The electric starting system of claim 7 , wherein the rechargeable battery further includes a display for providing information to a user.

18. An electric starting system for an internal combustion engine, comprising:

a rechargeable battery including two voltage output terminals and an enable terminal;

a battery receiver including a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and an enable terminal;

a starter motor configured to start the internal combustion engine;
