Abstract

Claims (40)

1. A starting battery for use with an electric starting system including a starter motor and a battery receiver, comprising:

a lithium-ion battery cell;

two voltage output terminals; and

an enable terminal;

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

wherein the enable terminal is configured to connect to an enable terminal of the battery receiver to receive an enable signal to the starting battery to allow the lithium-ion battery cell to provide power to the starter motor to start an internal combustion engine.

2. The starting battery of claim 1 , wherein the voltage output terminals of the starting battery are configured to connect to the voltage output terminals of the battery receiver before the enable terminal of the starting battery connects to the enable terminal of the battery receiver.

3. The starting battery of claim 1 , wherein if the enable terminal of the starting battery is not connected to the enable terminal of the battery receiver, the lithium-ion battery cell does not provide power to the starter motor.

4. The starting battery of claim 1 , wherein the terminals of the starting battery comprise female terminals.

5. The starting battery of claim 1 , further comprising:

a latch configured to engage a latching region of the battery receiver to secure the starting battery to the battery receiver.

6. The starting battery of claim 1 , further comprising:

a bottom side including a wall that separates a lower portion of the bottom side from an upper portion of the bottom side, wherein the wall is configured to contact a wall of the battery receiver to limit the travel of the starting battery relative to the battery receiver when attaching the starting battery to the battery receiver.

7. The starting battery of claim 6 , further comprising:

a plurality of apertures formed in the bottom side, wherein each aperture is sized and positioned to receive a guide of the battery receiver to guide the starting battery into the battery receptacle.

8. The starting battery of claim 1 , further comprising:

a display for providing information to a user.

9. The starting battery of claim 1 , wherein the lithium-ion battery cell is one of a plurality of lithium-ion battery cells.

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

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

a battery receiver including a battery receptacle configured to receive the lithium-ion battery, two voltage output terminals, and an enable terminal; 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 lithium-ion battery cell and the starter motor when the lithium-ion battery is attached to the battery receptacle; and

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

11. The electric starting system of claim 10 , 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.

12. The electric starting system of claim 10 , wherein the voltage output terminals of the battery receiver are configured to connect to the voltage output terminals of the lithium-ion-battery before the enable terminal of the battery receiver connects to the enable terminal of the lithium-ion battery.

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

14. The electric starting system of claim 10 , wherein the terminals of the lithium-ion battery comprise female terminals and the terminals of the battery receiver comprise male terminals.

15. The electric starting system of claim 10 , wherein the lithium-ion 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 lithium-ion battery to the battery receiver.

16. The electric starting system of claim 10 , wherein the lithium-ion battery is configured to be selectively attached to and removed from the battery receiver without tools.

17. The electric starting system of claim 10 , 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 lithium-ion 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 lithium-ion battery relative to the battery receiver when attaching the lithium-ion battery to the battery receiver.

18. The electric starting system of claim 17 , 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 lithium-ion 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.

19. The electric starting system of claim 17 , 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.

20. The electric starting system of claim 10 , wherein the lithium-ion battery further includes a display for providing information to a user.
