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.

Vehicle electric power take-off

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. An associated method includes controlling the plurality of switches to selectively connect the external charging terminals, the voltage converter, and the external load terminals; and controlling whether the voltage converter operates to increase or decrease voltage based on which one or more of the voltage converter, the external charging terminals, the external load terminals, and the traction battery are connected by the plurality of switches.
