Abstract

Systems and methods may coordinate and execute bidirectional energy transfer events between electrified vehicles and other devices or structures. Weather related data and/or grid related data may be leveraged for predicting the likelihood of power outage conditions of a grid power source. When power outage conditions are likely, a charging storage limit of a traction battery pack of the electrified vehicle may be automatically increased. The increased charging storage limit temporarily increases the energy storage capacity of the traction battery pack in anticipation of expected power outage conditions, thereby better preparing the traction battery pack for use as a backup power source during the power outage conditions.

First claim

What is claimed is:

1. A bidirectional energy transfer system, comprising:
a traction battery pack; and
a control module programmed to automatically increase a charging storage limit of the traction battery pack in response to predicting that a power outage condition of a grid power source is likely.

2. The system as recited in claim 1 , wherein the control module is programmed to predict that the power outage condition is likely based on weather related data received from a weather data server.

3. The system as recited in claim 1 , wherein the control module is programmed to predict that the power outage condition is likely based on data received from a grid announcement server associated with the grid power source.

4. The system as recited in claim 1 , wherein the control module is a component of an electrified vehicle that is powered by the traction battery pack.

5. The system as recited in claim 1 , wherein the control module is a component of a cloud-based storage system.

6. The system as recited in claim 1 , wherein the control module is programmed to increase the charging storage limit of the traction battery pack from 80% to 100% in response to predicting that the power outage condition is likely.

7. The system as recited in claim 1 , wherein the charging storage limit is part of a smart bidirectional charging schedule that is created by the control module in response to predicting that the power outage condition is likely.

8. The system as recited in claim 7 , wherein the control module is programmed to control a transfer of energy between the traction battery pack and a structure.

9. The system as recited in claim 8 , wherein the smart bidirectional charging schedule includes instructions for transferring power from the traction battery pack to the structure for powering an AC infrastructure of the structure in response to detecting an actual power outage condition.

10. The system as recited in claim 1 , wherein the control module is further programmed to:
notify a user in response to predicting that the power outage condition is likely; and
provide a list of available charging options for charging the traction battery pack or provide turn-by-turn instructions for guiding the user back to a home location.

11. A method, comprising:
automatically adjusting, via a control module of a bidirectional energy transfer system, a charging storage limit of a traction battery pack of an electrified vehicle when a power outage condition of a grid power source is predicted as being likely.

12. The method as recited in claim 11 , wherein automatically adjusting the charging storage limit includes:
increasing the charging storage limit of the traction battery pack from 80% to 100%.

13. The method as recited in claim 11 , wherein the control module is a component of the electrified vehicle.

14. The method as recited in claim 11 , wherein the control module is a component of a cloud-based server system.

15. The method as recited in claim 11 , comprising:
receiving weather related data from a weather data server; and
predicting whether or not the power outage condition is likely based on the weather related data.

16. The method as recited in claim 11 , comprising:
receiving data from a grid announcement server associated with the grid power source; and
predicting whether or not the power outage condition is likely based on the data from the grid announcement server.

17. The method as recited in claim 11 , comprising:
determining whether the electrified vehicle is at a home location;
determining whether the electrified vehicle is on-plug;
determining whether an actual power outage is occurring; and
delivering power from the traction battery pack to the home location when 1) the electrified vehicle is at the home location; 2) the electrified vehicle is on-plug; and 3) the actual power outage condition is occurring.

18. The method as recited in claim 11 , comprising:
determining whether the electrified vehicle is at a home location;
determining whether the electrified vehicle is on-plug;
charging the traction battery pack to the charging storage limit when the electrified vehicle is at the home location and is on-plug.

19. The method as recited in claim 18 , comprising:
notifying a user that the electrified vehicle is located in a power outage zone when the electrified vehicle is not at the home location; and
providing the user with a list of available charging options for charging the traction battery pack.

20. The method as recited in claim 18 , comprising:
notifying a user that the power outage condition is likely while the electrified vehicle is away from the home location; and
providing the user with turn-by-turn instructions for returning to the home location.
