Abstract

See full text

An AC inverter in a vehicle operates using a 24 V input when a vehicle powertrain is in a parked/idling state. A first 12 V battery is connected with a first bus segment. A second 12 V battery is connected with a second bus segment. A switch module selectably interconnects the first and second bus segments. In a nominal 12 V state, the batteries are connected in parallel from the bus segments to ground. In a dual voltage state, the batteries are connected in series so the first bus segment is at 12 V and the second bus segment is at 24 V. A first alternator driven by the powertrain provides a regulated voltage to the second bus segment, wherein the regulated voltage corresponds to 12 V when the switch module is in the nominal state and corresponds to 24 V when the switch module is in the dual voltage state.
