First Claim
1. An electrical system for a vehicle, comprising:
- a first power source generating a first voltage level, the first power source being in electrical communication with a first bus;
a second power source generating a second voltage level greater than the first voltage level, the second power source being in electrical communication with a second bus;
a starter generator configured to provide power to at least one of the first bus and the second bus;
at least one additional power source configured to provide power to at least one of the first bus and the second bus;
at least one power consumer in electrical communication with the first bus;
at least one power consumer in electrical communication with the second bus; and
a mode selector having at least a first position, a second position, and a third position,wherein the first bus is partitioned into at least a first sub-bus and a second sub-bus, andwherein neither the first sub-bus nor the second sub-bus is energized when the mode selector is in the first position, only the first sub-bus is energized when the mode selector is in the second position, and both the first sub-bus and the second sub-bus are energized when the mode selector is in the third position.

Abstract
An electrical system for a vehicle includes a first power source generating a first voltage level, the first power source being in electrical communication with a first bus. A second power source generates a second voltage level greater than the first voltage level, the second power source being in electrical communication with a second bus. A starter generator may be configured to provide power to at least one of the first bus and the second bus, and at least one additional power source may be configured to provide power to at least one of the first bus and the second bus. The electrical system also includes at least one power consumer in electrical communication with the first bus and at least one power consumer in electrical communication with the second bus.
