Abstract

A starter battery pack with a start button included as part of the starter battery pack is shown and described. The starter battery pack includes a start button that, when the starter battery pack is received within a receptacle of outdoor power equipment, such as a lawn tractor, allows the starter battery pack to provide power to a starting circuit of the power equipment. The battery pack is selectively rechargeable and preferably is a type of battery, such as lithium ion, that can be repeatedly discharged and recharged without affecting battery life. When the starter battery pack is received within the receptacle, activation of the start button provides current and voltage front the starter battery pack to an electric starter motor, which initiates operation of the internal combustion engine.

Claims (29)

1. Outdoor power equipment comprising:

an internal combustion engine;

an electric starter motor coupled to the internal combustion engine to start the internal combustion engine;

a battery receptacle mounted on the outdoor power equipment and electrically connected to the starter motor; and

a starter battery pack configured to be received within the battery receptacle to provide electric power to the starter motor, wherein the starter battery pack includes a start button such that when the starter battery pack is received within the battery receptacle and the start button is activated, electric power is supplied to the starter motor.

2. The outdoor power equipment of claim 1 wherein the starter battery pack includes a plurality of battery cells and the plurality of battery cells and the start button are contained within an outer housing.

3. The outdoor power equipment of claim 2 wherein the start button is located on the outer housing such that the start button is accessible by a user when the starter battery pack is received in the battery receptacle.

4. The outdoor power equipment of claim 1 wherein the starter battery pack includes at least one indicator to visually indicate an operating parameter of the starter batter pack or the internal combustion engine.

5. The outdoor power equipment of claim 4 wherein the operating parameter is at least one of a state of charge of the starter battery pack and an operating status of the internal combustion engine.

6. The outdoor power equipment of claim 1 wherein the starter battery pack is removable without tools.

7. The outdoor power equipment of claim 1 further comprising an engine control circuit configured to allow electric power to be provided to the starter motor upon activation of the start button when the internal combustion engine is not operating and terminate operation of the internal combustion engine upon activation of the start button when the internal combustion engine is operating.

8. The outdoor power equipment of claim 7 wherein the engine control circuit is located on the outdoor power equipment.

9. A lawn tractor comprising:

an internal combustion engine;

an electric starter motor coupled to the internal combustion engine to start the internal combustion engine; and

a starter battery pack configured to be received on the lawn tractor to provide electric power to the starter motor, wherein the starter battery pack includes a start button such that when the starter battery pack is received on the lawn tractor and the start button is activated, electric power is supplied to the starter motor.

10. The lawn tractor of claim 9 further comprising a battery receptacle positioned on the lawn tractor and sized to receive the starter battery pack and allow removal of the starter battery pack without tools.

11. The lawn tractor of claim 10 wherein the battery receptacle electrically connects the starter battery pack to the starter motor.

12. The lawn tractor of claim 10 wherein the battery receptacle is contained within a dashboard of the lawn tractor.

13. The lawn tractor of claim 9 wherein the starter battery pack includes at least one indicator to visually indicate at least one of an operating parameter of the starter battery pack.

14. The lawn tractor of claim 9 wherein the starter battery pack includes at least one indicator to visually indicate an operating parameter of the lawn tractor.

15. The lawn tractor of claim 9 further comprising an engine control circuit configured to allow electric power to be provided to the starter motor upon activation of the start button when the internal combustion engine is not operating and to terminate operation of the internal combustion engine upon activation of the start button when the internal combustion engine is operating.

16. A starting circuit for providing electric power to a starter motor to start an internal combustion engine of outdoor power equipment, comprising:

a battery receptacle mounted on the outdoor power equipment and electrically connected to the starter motor; and

a starter battery pack configured to be removably received in the battery receptacle to provide electric power to the starter motor, wherein the starter battery pack includes a start button such that when the starter battery pack is received within the battery receptacle and the start button is activated, electric power is supplied to the starter motor.

17. The starting circuit of claim 16 wherein the starter battery pack includes a plurality of battery cells and the plurality of battery cells and the start button are contained within an outer housing.

18. The starting circuit of claim 17 wherein the plurality of battery cells are lithium ion battery cells.

19. The starting circuit of claim 16 further comprising an engine control circuit configured to allow electric power to be provided to the starter motor upon activation of the start button when the internal combustion engine is not operating and to terminate operation of the internal combustion engine upon activation of the start button when the internal combustion engine is operating.

20. The starting circuit of claim 16 wherein the battery receptacle and the starter battery pack communicate with each other to authenticate the starter battery pack with the battery receptacle.
