Abstract
An electric power management system for a vehicle includes a first power bus arranged in parallel with a second power bus between first and second nodes. A third power bus couples a first battery and an auxiliary load at the second node. The second power bus couples a starter, a second battery and a generator at the first node, and selectively couples the first node to the second node when a first switch is activated. The second battery couples to the first node when a second switch is activated and the engine starter couples to the first node when a starter switch is activated. The second power bus couples the first node to the second node when a third switch is activated. A controller monitors states of charge of the first battery and the second battery and controls activations of the first switch, the second switch and the third switch.
