Method and apparatus for electric power management in a vehicle

This invention describes a system for managing the electrical power in a vehicle. It uses a DC/DC converter to change high-voltage power from the main source into lower-voltage power for accessories like lights and radios. The system monitors the low-voltage battery's charge and temperature, and the total electrical load, adjusting the converter's output voltage. Specifically, it reduces the voltage to a minimum level when the vehicle is moving slowly and there's a high electrical load, especially if headlamps are on.
