Abstract

System, methods, and other embodiments described herein relate to controlling power delivery to a consumer appliance in a vehicle. In one embodiment, a method includes receiving a connection signal from the consumer appliance indicating presence of the consumer appliance. The method also includes directly providing electrical power from a propulsion device providing DC voltage to the consumer appliance without substantially lowering a voltage level of the propulsion device.

First claim

What is claimed is:

1. A power delivery system for controlling power delivery to a consumer appliance in a vehicle, the power delivery system comprising:
one or more processors; and
a memory communicably coupled to the one or more processors and storing:
a connection module including instructions that when executed by the one or more processors cause the one or more processors to:
receive a connection signal from the consumer appliance indicating presence of the consumer appliance, wherein the connection signal includes power requirements for the consumer appliance; and

a delivery module including instructions that when executed by the one or more processors cause the one or more processors to:
directly provide electrical power from a propulsion device providing DC voltage to the consumer appliance without substantially lowering a voltage level of the propulsion device.

2. The power delivery system of claim 1 , wherein the delivery module further includes instructions to directly provide the electrical power from the propulsion device providing DC voltage to the consumer appliance without converting a voltage type of the propulsion device from DC to AC.

3. The power delivery system of claim 1 , wherein the delivery module further includes instructions to disengage the consumer appliance based the connection signal.

4. The power delivery system of claim 1 , wherein the delivery module further includes instructions to receive a propulsion device state from the propulsion device, and to determine whether the propulsion device state fulfills the power requirements.

5. The power delivery system of claim 4 , wherein the delivery module further includes instructions to output, in response to a determination that the propulsion device state does not fulfill the power requirements, a message to at least one of an output system of the vehicle or a wireless device.

6. The power delivery system of claim 4 , wherein the propulsion device state includes at least one of an available energy, a state of charge, an output voltage, or a propulsion device temperature.

7. The power delivery system of claim 4 , wherein the delivery module further includes instructions to output, in response to a determination that the propulsion device state fulfills the power requirements, a supply signal to a power distributor, the power distributor configured to deliver the electrical power from the propulsion device to the consumer appliance in response to a receipt of the supply signal.

8. The power delivery system of claim 4 , wherein the delivery module further includes instruction to output, in response to a determination that the propulsion device state fulfills the power requirements, a supply signal to the propulsion device, the propulsion device configured to deliver the electrical power to the consumer appliance in response to a receipt of the supply signal.

9. A power delivery system for controlling power delivery to a consumer appliance in a vehicle, the power delivery system comprising:
one or more processors; and
a memory communicably coupled to the one or more processors and storing:
a connection module including instructions that when executed by the one or more processors cause the one or more processors to:
receive a connection signal from the consumer appliance indicating presence of the consumer appliance, wherein the connection signal includes power requirements for the consumer appliance; and

a delivery module including instructions that when executed by the one or more processors cause the one or more processors to:
directly provide electrical power from a propulsion device providing DC voltage to the consumer appliance without substantially lowering a voltage level of the propulsion device;
receive a propulsion device state from the propulsion device, and to determine whether the propulsion device state fulfills the power requirements; and
selectively engage and disengage one or more consumer appliances based on the propulsion device state.

10. The power delivery system of claim 1 , wherein the vehicle includes a compartment accessible from an exterior of the vehicle, the compartment configured to receive the consumer appliance.

11. A method for controlling power delivery to a consumer appliance in a vehicle, comprising:
receiving a connection signal from the consumer appliance indicating presence of the consumer appliance, wherein the connection signal includes power requirements for the consumer appliance; and
directly providing electrical power from a propulsion device providing DC voltage to the consumer appliance without substantially lowering a voltage level of the propulsion device.

12. The method of claim 11 , wherein the directly providing the electrical power from the propulsion device providing DC voltage to the consumer appliance comprises directly providing the electrical power from the propulsion device providing DC voltage to the consumer appliance without converting a voltage type of the propulsion device from DC to AC.

13. The method of claim 11 , further comprising:
receiving a propulsion device state from the propulsion device; and
determining whether the propulsion device state fulfills the power requirements.

14. The method of claim 13 , further comprising:
in response to determining the propulsion device state fulfills the power requirements, outputting a supply signal to a power distributor, the power distributor configured to deliver the electrical power from the propulsion device to the consumer appliance in response to a receipt of the supply signal.

15. The method of claim 13 , further comprising:
in response to determining the propulsion device state fulfills the power requirements, outputting a supply signal to the propulsion device, the propulsion device configured to deliver the electrical power to the consumer appliance in response to a receipt of the supply signal.

16. The method of claim 13 , further comprising:
selectively engaging and disengaging one or more consumer appliances based on the propulsion device state.

17. A non-transitory computer-readable medium for controlling power delivery to a consumer appliance in a vehicle and storing instructions that when executed by one or more processor cause the one or more processors to:
receive a connection signal from the consumer appliance indicating presence of the consumer appliance, wherein the connection signal includes power requirements for the consumer appliance; and
directly provide electrical power from a propulsion device providing DC voltage to the consumer appliance without substantially lowering a voltage level of the propulsion device.

18. The non-transitory computer-readable medium of claim 17 , wherein the instructions that directly provide the electrical power from the propulsion device providing DC voltage to the consumer appliance comprise instructions that directly provide the electrical power from the propulsion device providing DC voltage to the consumer appliance without converting a voltage type of the propulsion device from DC to AC.

19. The non-transitory computer-readable medium of claim 17 , wherein the computer-readable medium further includes instructions that when executed by the one or more processors cause the one or more processors to:
receive a propulsion device state from the propulsion device, and determine whether the propulsion device state fulfills the power requirements.

20. The non-transitory computer-readable medium of claim 19 , wherein the computer-readable medium furthe
