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.
Claims20
An electric power take-off system for a vehicle, comprising:
- a connector including at least one pin configured to transfer communication data and a first pin and a second pin configured to transfer electric power;
- a DC/DC converter electrically coupled to a traction battery and a first relay group, the first relay group electrically coupled to the first pin and the second pin;
- and
- a power source electrically coupled to a second relay group, the second relay group electrically coupled to the first pin and the second pin.
An electric power take-off method for a vehicle, comprising:
- supplying power from a first power source to a first pin and a second pin of a connector while a second power source is not electrically coupled to the first pin and the second pin, where the first power source is a DC/DC converter, and where the second power source is an electric energy storage device;
- and
- supplying power from the second power source to the first pin and the second pin of the connector while the first power source is not electrically coupled to the first pin and the second pin, where the first power source outputs a first voltage and the second power source outputs a second voltage, the first voltage greater than the second voltage.
A system for receiving electric power from an electric power take-off system of a vehicle, comprising:
- a connector including at least one pin configured to transfer communication data and a first pin and a second pin configured to transfer electric power;
- a DC/DC converter electrically coupled to a capacitor and a controller, the DC/DC converter electrically coupled to the first pin and the second pin;
- and
- an accessory load coupled to a relay group, the relay group electrically coupled to the first pin and the second pin.
