Abstract
Systems for exporting power from a vehicle with an engine are provided. Also provided is a multi-vehicle docking station having multiple connections for multiple vehicles to connect to and multiple power outputs, whereby vehicles may provide power to an external electrical load via the multi-vehicle docking station. One or more vehicles may provide export power to the load based on a remaining power capacity and fuel level in the vehicles.
Claims27
A power system for a vehicle comprising:
- a first inverter coupled to a generator, where the generator is mechanically coupleable directly to a crankshaft of an engine, the first inverter, when the generator is coupled directly to the crankshaft of the engine, is configured to receive three-phase AC power from the generator when the engine is ON and provide DC power for a DC link;
- a second inverter coupled to the DC link and configured to receive the DC power from the first inverter and provide three-phase AC power to a first power path and a second power path;
- a switch configured to switch the provided three-phase AC power from the second inverter to one of the first power path and the second power path, the second power path supplying power to an external load;
- and
- a processor configured to control the switch and cause the three-phase AC power to be supplied to the external load or to the first power path at determined frequency and determined voltage, when supplying power to the external load, the determined frequency and the determined voltage meeting power requirements for the external load.
