Abstract
A method and system for controlling power to a cranking subsystem in a device having a power source is disclosed. The cranking subsystem is coupled to an engine and a starter that allows a user to activate the cranking subsystem. The method and system include providing a switch and at least one controller. The switch is coupled between the power source and the cranking subsystem. The at least one controller is coupled with the switch and is for controlling the switch to be open or closed based on the starter being used to activate the cranking subsystem and at least one other criteria. The at least one other criteria is programmed into the controller.
Claims22
A system for controlling power to a cranking subsystem in a device having a power source, the cranking subsystem coupled to an engine and a starter for allowing a user to activate the cranking subsystem, the system comprising:
- a switch coupled between the power source and the cranking subsystem;
- and
- at least one controller, coupled with the switch, for controlling the switch to be open or closed based on the starter being used to activate the cranking subsystem and at least one other criteria, the at least one other criteria being programmed into the controller, the at least one other criteria including the cranking subsystem running for less than a particular time at a particular current, the controller opening the switch to cut off power to the cranking subsystem if greater than or equal to the particular current has flowed to the cranking subsystem through the switch for greater than or equal to the particular time.
A method for controlling power to a cranking subsystem in a device having a power source, the cranking subsystem coupled to an engine and a starter for allowing a user to activate the cranking subsystem, the method comprising the steps of:
- providing a switch coupled between the power source and the cranking subsystem;
- and
- providing at least one controller, coupled with the switch, for controlling the switch to be open or closed based on the starter being used to activate the cranking subsystem and at least one other criteria, the at least one other criteria being programmed into the controller, the at least one other criteria including the cranking subsystem running for less than a particular time at a particular current, the controller opening the switch to cut off power to the cranking subsystem if greater than or equal to the particular current has flowed to the cranking subsystem through the switch for greater than or equal to the particular time.
A method for controlling power to a cranking subsystem in a device having a power source, the cranking subsystem coupled to an engine and a starter for allowing a user to activate the cranking subsystem, the method comprising the steps of:
- utilizing a switch and at least one controller to control power being provided to the cranking subsystem, the switch coupled between the power source and the cranking subsystem, the at least one controller coupled with the switch and controlling the switch to be open or closed based on the starter being used to activate the cranking subsystem and at least one other criteria, the at least one other criteria being programmed into the controller, the at least one other criteria including the cranking subsystem running for less than a particular time at a particular current, the controller opening the switch to cut off power to the cranking subsystem if greater than or equal to the particular current has flowed to the cranking subsystem through the switch for greater than or equal to the particular time.
