Abstract

An electric vehicle charging control device includes an electronic dynamic charging schedule generator, a non-transitory computer readable medium and an electronic communicator. The non-transitory computer readable medium stores vehicle profile data and building profile data. The electronic communicator is configured to receive profile updates to the vehicle profile data from an electronic user interface. The electronic controller is programmed to generate a driver charging profile based on the vehicle profile data and the building profile data. The electronic controller is programmed to update the driver charging profile based on the electric vehicle user's behavior. The electronic controller is programmed to generate a charging schedule for the electric vehicle based on the updated driver charging profile. The electronic controller is programmed to controlling the charging port in accordance with the charging schedule upon the electric vehicle user confirming acceptance of the charging schedule on the electronic user interface.

First claim

What is claimed is:

1 . An electric vehicle charging control device comprising:
an electronic dynamic charging schedule generator having an electronic controller configured to determine when an electric vehicle user accesses a charging port provided at a building structure being powered by an electric source; a non-transitory computer readable medium storing vehicle profile data for the electric vehicle and building structure profile data for the building structure, the building structure profile data including building electric load and utility use data; and an electronic communicator configured to receive profile updates to the vehicle profile data from an electronic user interface, the electronic controller being programmed to
generate a driver charging profile based on the vehicle profile data and the building structure profile data,
update the driver charging profile based on the electric vehicle user's behavior,
generate a charging schedule for the electric vehicle based on the updated driver charging profile, the charging schedule including a charging end time determined from a current state-of-charge of the electric vehicle, and
control the charging port in accordance with the charging schedule upon the electric vehicle user confirming acceptance of the charging schedule on the electronic user interface.

2 . The electric vehicle charging control device according to claim 1 , wherein
the charging schedule has a charge period in which the electric vehicle is receiving charge from the building structure and a discharge period in which the electric vehicle is providing charge to the building structure.

3 . The electric vehicle charging control device according to claim 2 , wherein
the electronic controller is programmed to determine that the charge period substantially corresponds to a period in which the building structure is in a low electric use period based on the building structure profile data.

4 . The electric vehicle charging control device according to claim 3 , wherein
the electronic controller is programmed to determine that the discharge period corresponds to a period in which the building structure is in a high electric use period based on the building structure profile data.

5 . The electric vehicle charging control device according to claim 4 , wherein
the electronic controller is further programmed to determine a recharge period in which the electric vehicle further receives charge from the building structure.

6 . The electric vehicle charging control device according to claim 5 , wherein
the electronic controller is further programmed to update the driver charging profile upon the electric vehicle initiating a charging incident.

7 . The electric vehicle charging control device according to claim 5 , wherein
the electronic controller is further programmed to update the driver charging profile upon the electric vehicle ending a charging incident.

8 . The electric vehicle charging control device according to claim 5 , wherein
the electronic controller is further programmed to update the driver charging profile by calculating an average charging period per instance for the electric vehicle.

9 . The electric vehicle charging control device according to claim 8 , wherein
the electronic controller is further programmed to update the driver charging profile by calculating an aggregate electric demand of the building structure.

10 . An electronic dynamic charging control method to be executed by a computer, the method comprising:
determining when an electric vehicle user accesses a charging port provided at a building structure being powered by an electric source; accessing vehicle profile data for the electric vehicle from a non-transitory computer readable medium storing the vehicle profile data; accessing building structure profile data for the building, the building structure profile data including building electric load and utility use data; receiving profile updates to the vehicle profile data from a user interface; generating a charging schedule for the electric vehicle based on an updated driver charging profile including the profile updates, the charging schedule including a charging end time determined from a current state-of-charge of a vehicle battery; and controlling the charging port in accordance with the charging schedule upon the electric vehicle user confirming acceptance of the charging schedule on the electronic user interface.

11 . The electronic dynamic charging control method according to claim 10 , wherein
the charging schedule has a charge period in which the electric vehicle is receiving charge from the building structure and a discharge period in which the electric vehicle is providing charge to the building structure.

12 . The electronic dynamic charging control method according to claim 11 , further comprising
determining that the charge period substantially corresponds to a period in which the building structure is in a low electric use period based on the building structure profile data.

13 . Electronic dynamic charging control method according to claim 12 , further comprising
determining that the discharge period corresponds to a period in which the building structure is in a high electric use period based on the building structure profile data.

14 . The electronic dynamic charging control method according to claim 13 , further comprising
determining a recharge period in which the electric vehicle further receives charge from the building structure.

15 . The electronic dynamic charging control method according to claim 14 , further comprising
updating the driver charging profile upon the electric vehicle initiating a charging incident.

16 . The electronic dynamic charging control method according to claim 15 , further comprising
updating the driver charging profile upon the electric vehicle ending a charging incident.

17 . The electronic dynamic charging control method according to claim 16 , further comprising
updating the driver charging profile by calculating an average charging period per instance for the electric vehicle.

18 . The electronic dynamic charging control method according to claim 17 , further comprising
updating the driver charging profile by calculating an aggregate electric demand of the building structure.
