A power system for a vehicle comprises a first power supply network configured to operate at a first voltage. The first power supply network comprises a first alternator, a starter motor, and a battery conductively connected to the first alternator and the starter motor. The system further comprises a second power supply network configured to operate at a second voltage. The second power supply network comprises a second alternator, a power supply receptacle configured to output power to an external accessory, and a capacitive energy storage device conductively connected to the second alternator and the power supply receptacle. A directional conduction device interconnects the first power supply network and the second power supply network.

Vehicle auxiliary power supply system

A vehicle operates an internal combustion engine according to an automatic start-stop function to reduce fuel consumption. A first DC bus is adapted to connect to a plurality of DC loads. A primary battery is coupled between the first DC bus and a ground. A first alternator is driven by the internal combustion engine to supply electrical power to the first DC bus. A second DC bus is connected to a positive terminal of an auxiliary battery. A negative terminal of the auxiliary battery is connected to the first DC bus. A second alternator is driven by the internal combustion engine to supply electrical power to the second bus at a voltage corresponding to a sum of voltages of the primary and auxiliary batteries. An inverter receives electrical power from the second DC bus to generate an AC output adapted to connect to accessory AC loads.
