Power management system and method for an automobile

1. A system for managing a vehicle's electrical power consumption, the vehicle having a plurality of electrical components, the electrical components having varying power requirements, the system comprising:

a first battery for supplying power to at least one of the plurality of electrical components;

a second battery for supplying power to at least one other of the plurality of electrical components;

an isolator for electrically isolating the first battery from the second battery;

a power supply connected to at least one of the first and second batteries for supplying a regulated supply of electrical power to at least one of the plurality of electrical components;

a power distributor in communication with the power supply and at least one of the first and second batteries for selectively providing electrical power to the plurality of electrical components; and

a processor in communication with the power supply and the power distribution box, wherein the processor is configured to execute program code for managing the vehicle's electrical power consumption by manipulating an output of the power distributor.

2. The system of claim 1 further comprising an override switch for bypassing the isolator and electrically connecting the first and second batteries.

3. The system of claim 1 further comprising an alternator in communication with the first and second batteries for electrically charging same.

4. The system of claim 3 wherein the alternator is connected to the isolator such that the first and second batteries are selectively charged.

5. The system of claim 1 wherein the power supply further comprises a plurality of separate power supply portions that may be independently activated and deactivated.

6. The system of claim 5 wherein the plurality of separate power supply portions further comprises a processor power supply portion for supplying power to the processor.

7. The system of claim 1 further comprising a vehicle control module in communication with the processor and the power distributor, wherein the processor manipulates the vehicle control module to output a control signal to the power distributor to change the vehicle's power consumption.

8. The system of claim 1 further comprising a vehicle status indicator in communication with the processor for communicating a vehicle status thereto.

9. The system of claim 8 wherein the vehicle status indicator is in communication with the power supply for receiving electrical power there from.

10. A method for managing a vehicle's electrical power consumption, the vehicle having a plurality of electrical components, the electrical components having varying power requirements, the method comprising:

supplying power to at least one of the plurality of electrical components using a first battery;

supplying power to at least one other of the plurality of electrical components using a second battery;

electrically isolating the first battery from the second battery using an isolator;

supplying a regulated source of electrical power to at least one of the plurality of electrical components using a power supply;

selectively providing electrical power to the plurality of electrical components using a power distributor in communication at least one of the first and second batteries and the power supply; and

manipulating the power distributor by executing program code on a processor configured to manage the vehicle's electrical power consumption, wherein the processor is an communication with the power supply and the power distributor.

11. The method of claim 10 further comprising bypassing the isolator and electrically connecting the first and second batteries using an override switch.

12. The method of claim 10 further comprising charging the first and second batteries using an alternator in communication therewith.

13. The method of claim 12 further comprising selectively charging the first and second batteries using the alternator and the isolator.

14. The method of claim 10 further comprising outputting a control signal to the power distributor to change the vehicle's power consumption using a vehicle control module in communication with the processor and the power distributor.

15. The method of claim 10 further comprising communicating a vehicle status signal indicative of a status of the vehicle.

16. The method of claim 15 further comprising supplying electrical power to a vehicle status indicator in communication with the power supply.

17. The method of claim 10 wherein manipulating the power distributor further comprises reducing the vehicle power consumption to a first predefined power shutdown stage.

18. The method of claim 17 wherein reducing the vehicle power consumption further comprises limiting a current draw to a predefined maximum current draw.

19. The method of claim 10 wherein manipulating the power distributor further comprises reducing the vehicle power consumption to a second predefined power shutdown stage.

20. The method of claim 19 wherein reducing the vehicle power consumption further comprises limiting a voltage level drop to a predefined minimum battery voltage level.

21. The method of claim 10 wherein manipulating the power distributor further comprises reducing the vehicle power consumption to a third predefined power shutdown stage.

22. The method of claim 10 wherein manipulating the power distributor further comprises reducing vehicle power consumption after a predefined default time limit has expired.
