Abstract
A vehicle power and battery management system. The system includes a high-voltage DC bus, a first battery, a second battery, at least one bidirectional DC/DC converter, and a controller. The controller monitors the state of at least one of the high-voltage bus, the first battery and the second battery, and transfers energy between at least two of the high-voltage bus, first battery and second battery with the bidirectional DC/DC converter. A method employs the system.
