Abstract: Methods and systems are provided for combining output of two or more power sources of an electric vehicle to supply electric power to an electric power consumer that is external of a vehicle. In one example, output of the two or more power sources is combined via an aggregation cable.

Abstract: While a state of charge of a supplemental battery, that provides power to an electrical bus via a first DC/DC converter, is greater than a predefined threshold and responsive to a magnitude of current associated with loads on the electrical bus exceeding a predefined value, a controller reduces a setpoint of the first DC/DC converter to equal that of a second DC/DC converter, that transfers power between the electrical bus and a traction battery, such that the loads are powered by the supplemental and traction batteries.

Abstract: Electric vehicle supply equipment may include a pair of parallel contactors that electrically connect a vehicle with a power source. It also includes a controller that closes one of the pair before the other of the pair based on a cumulative exposure to in-rush current of each of the pair.

Abstract: Methods and systems are provided for communicating operating conditions and operational limitations of an electric coupler that is external of a vehicle to the vehicle. In one example, functionality of a proximity detection circuit is enhanced to double as a serial communications link between a vehicle and an electric coupler.

Abstract: Methods and systems for supplying electrical power from a vehicle to an external accessory are described. In one example, two different voltages may be applied at different times to a connector so that the external accessory device need not include a battery. In particular, a first voltage may power a main load of the external accessory and a second voltage may power a microcontroller that communicates with the vehicle.

Abstract: An electrified vehicle includes a synchronous switching DC/DC voltage converter, switches configured to selectively connect external charging terminals to a traction battery, the voltage converter, and external load terminals, and at least one controller programmed to operate the voltage converter and control the switches to connect the external charging terminals to the voltage converter and the external load terminals based on nominal voltage of the traction battery relative to voltage at the external charging terminals and a requested voltage supplied to the external load terminals.
