Abstract

A device, method, and system includes an integrated battery power controller configured to monitor a voltage difference between a first output terminal and a second output terminal; disconnect, via a switch, at least one of the first output terminal and the second output terminal from a power source if the voltage difference between the first output terminal and the second output terminal is less than a predetermined voltage threshold; and connect, via the switch, both the first output terminal and the second output terminal to the power source if the voltage difference between the first output terminal and the second output terminal is equal to or greater than the predetermined voltage threshold.

Claims (45)

1. A method for integrated battery power control, comprising:

monitoring a voltage difference between a first output terminal and a second output terminal;

disconnecting at least one of the first output terminal and the second output terminal from a power source if the voltage difference between the first output terminal and the second output terminal is less than a predetermined voltage threshold; and

providing coupling of both the first output terminal and the second output terminal to the power source if the voltage difference between the first output terminal and the second output terminal is equal to or greater than the predetermined voltage threshold.

2. The method of claim 1 , further comprising:

receiving a manual input to connect the first output terminal and the second output terminal to the power source; and

coupling the first output terminal and the second output terminal to the power source based on the manual input.

3. The method of claim 1 , further comprising:

receiving a manual input to disconnect the first output terminal and the second output terminal from the power source; and

decoupling the first output terminal and the second output terminal from the power source based on the manual input.

4. An apparatus, comprising:

a power source;

a first output terminal;

a second output terminal;

a switch coupled to the first output terminal and the second output terminal;

a switch controller coupled to the switch, the switch including one or more hardware, operational logic, or software features configured to:

monitor a voltage difference between the first output terminal and the second output terminal;

disconnect, via the switch, at least one of the first output terminal and the second output terminal from the power source if the voltage difference between the first output terminal and the second output terminal is less than a predetermined voltage threshold; and

connect, via the switch, both the first output terminal and the second output terminal to the power source if the voltage difference between the first output terminal and the second output terminal is equal to or greater than the predetermined voltage threshold.

5. A battery power saving device, comprising:

a first output terminal;

a second output terminal;

a switch coupled to the first output terminal and the second output terminal;

a switch controller coupled to the switch, the switch controller including:

a monitoring component for monitoring a voltage difference between the first output terminal and the second output terminal;

a coupling disconnect component for disabling power delivery, via the switch, to at least one of the first output terminal and the second output terminal, the power delivery being communicated from a power source if the voltage difference between the first output terminal and the second output terminal is less than a predetermined voltage threshold; and

a coupling connect component for enabling power delivery, via the switch, to both the first output terminal and the second output terminal from the power source if the voltage difference between the first output terminal and the second output terminal is equal to or greater than the predetermined voltage threshold.

6. A system, comprising:

means for monitoring a voltage difference between a first output terminal and a second output terminal;

means for disconnecting at least one of the first output terminal and the second output terminal from a power source if the voltage difference between the first output terminal and the second output terminal is less than a predetermined voltage threshold; and

means for connecting both the first output terminal and the second output terminal to the power source if the voltage difference between the first output terminal and the second output terminal is equal to or greater than the predetermined voltage threshold.

7. The system of claim 6 , further comprising:

means for receiving a manual input to connect the first output terminal and the second output terminal to the power source; and

means for coupling the first output terminal and the second output terminal to the power source based on the manual input.

8. The system of claim 6 , further comprising:

means for receiving a manual input to disconnect the first output terminal and the second output terminal from the power source; and

means for decoupling the first output terminal and the second output terminal from the power source based on the manual input.
