Claim 10:
11. A vehicle power system, comprising:
a vehicle, wherein the vehicle comprises an electrical distribution system;
an auxiliary power unit attached to the vehicle and electrically connected to provide electrical power to the vehicle via the electrical distribution system, the auxiliary power unit comprising:
a fuel cell comprising a first DC output and a heat output;
a pressure vessel adapted to provide pressurized hydrogen to the fuel cell;
an electrical storage unit comprising a DC input coupled to the first DC output of the fuel cell, the electrical storage unit further comprising a second DC output;
an inverter coupled to the second DC output of the electrical storage unit to receive power from the electrical storage unit, the inverter comprising a first AC output;
a contactor connected between the first AC output and an AC load bus, the AC load bus comprising an AC voltage; and
a controller comprising inputs adapted to sense a phase, a frequency, and a magnitude of the first AC output and the AC voltage, wherein the controller controls the phase, the frequency, and the magnitude of the first AC output of the inverter;
wherein the controller further comprises an output command to selectively activate the contactor when a relationship between the phase, the frequency, and the magnitude of the first AC output and the AC voltage are substantially matched;
wherein the heat output provides heat to the vehicle;
wherein the first AC output provides electrical power to the vehicle via the electrical distribution system; and
wherein the controller is further adapted to communicate with a remote computing device.
