Abstract

A vehicle includes a traction battery, a human-machine interface (HMI), and a controller. The controller responsive to detecting electric vehicle supply equipment (EVSE) utilizing multiple price tiers corresponding to multiple maximum charge powers, outputs a message indicating a charge price corresponding to the maximum charge power for each of the price tiers via the HMI. The controller also, responsive to receiving user input indicating an adjusted maximum charge power less that a default maximum charge power of the vehicle, sends the adjusted maximum charge power to the EVSE and permits charging from the EVSE at or below the adjusted maximum charge power.

First claim

What is claimed is:

1. A vehicle, comprising:
a traction battery;
a human-machine interface (HMI); and
a controller programmed to
responsive to detecting electric vehicle supply equipment (EVSE) utilizing multiple price tiers corresponding to multiple default maximum charge powers, output a message indicating a charge price corresponding to the default maximum charge power for each of the price tiers via the HMI,
responsive to receiving user input defining an adjusted maximum charge power different than the default maximum charge powers and less than a greatest of the default maximum charge powers, send the adjusted maximum charge power to the EVSE and permit charging from the EVSE at or below the adjusted maximum charge power, and
responsive detecting a vehicle charge preference matching one of the multiple price tiers of the EVSE, automatically select a previously set maximum charge power and send the previously set maximum charge power to the EVSE.

2. The vehicle of claim 1 , wherein the vehicle charge preference matches one of the price tiers when a charge price difference between the charge preference and price for each tier is within a price threshold.

3. The vehicle of claim 1 , wherein the controller is further programmed to record the adjusted maximum charge power.

4. The vehicle of claim 1 , wherein the controller is further programmed to, responsive to detecting the EVSE utilizing a universal price structure, automatically select the default maximum charge power and send the default maximum charge power to the EVSE.

5. A method comprising:
in a presence of electric vehicle supply equipment (EVSE) utilizing multiple price tiers corresponding to multiple default maximum charge powers, outputting a message indicating a charge price corresponding to the default maximum charge power for each of the price tiers;
receiving input indicating a user specified adjusted maximum charge power different than the default maximum charge powers;
permitting charging from the EVSE at or below the adjusted maximum charge power; and
automatically selecting a previously set maximum charge power and sending the previously set maximum charge power to the EVSE responsive to detecting a vehicle charge preference matching one of the multiple price tiers of the EVSE.

6. The method of claim 5 , wherein the vehicle charge preference matches one of the price tiers when a charge price difference between the charge preference and price for each tier is within a price threshold.

7. The method of claim 5 further comprising sending the adjusted maximum charge power to the EVSE.

8. The method of claim 6 further comprising recording the adjusted maximum charge power.

9. The method of claim 5 further comprising automatically selecting the default maximum charge power and sending the default maximum charge power to the EVSE responsive to detecting the EVSE utilizing a universal price structure.

10. A charge system comprising:
a controller programmed to
control charging from a charge station based on a user defined adjusted maximum charge power different than default maximum charge powers available from the charge station,
output a message that the charge station is utilizing a plurality of price tiers corresponding to the default maximum charge powers and indicating a charge price corresponding to each of the price tiers, and receive user input defining the user defined adjusted maximum charge power, and
automatically select a previously set maximum charge power and send the previously set maximum charge power to the charge station responsive to detecting a vehicle charge preference matching one of the multiple price tiers of the charge station.

11. The charge station of claim 10 , wherein the vehicle charge preference matches one of the price tiers when a charge price difference between the charge preference and price for each tier is within a price threshold.

12. The charge station of claim 10 , wherein the controller is further programmed to send the adjusted maximum charge power to the charge station.

13. The charge station of claim 10 , wherein the controller is further programmed to record the adjusted maximum charge power.

14. The charge station of claim 10 , wherein the controller is further programmed to automatically select the default maximum charge power and send the default maximum charge power to the charge station responsive to detecting the charge utilizing a universal price structure.
