Abstract

Systems and methods may coordinate and execute bidirectional energy transfer events between electrified vehicles and one or more participating electrified recreational vehicles. The proposed systems and methods may be configured to provide charging alert notifications from the electrified vehicle to the one or more electrified recreational vehicles during group off-roading events. The charging alert notifications indicate the need for the one or more electrified recreational vehicles to return to the electrified vehicle for charging during the off-roading event in order to avoid a no start/stranded condition.

First claim

What is claimed is:

1. A vehicle-to-recreational vehicle energy transfer system, comprising:
an electrified vehicle;
an electrified recreational vehicle; and
a control module programmed to command communication of a charging alert notification to the electrified recreational vehicle when a no start/stranded condition of the electrified recreational vehicle is predicted to be likely.

2. The system as recited in claim 1 , wherein the electrified vehicle includes a first traction battery pack and a first electric machine, and the electrified recreational vehicle includes a second traction battery pack and a second electric machine.

3. The system as recited in claim 1 , wherein the control module is programmed to predict that the no start/stranded condition is likely when greater than a predefined percentage of a remaining state of charge of a traction battery pack of the electrified recreational vehicle is required in order for the electrified recreational vehicle to travel a relative distance between the electrified recreational vehicle and the electrified vehicle.

4. The system as recited in claim 1 , wherein the control module is programmed to predict that the no start/stranded condition is likely when a remaining state of charge of a traction battery pack of the electrified recreational vehicle is less than or equal to a predefined percentage of an amount of charge required to reach a current location of the electrified recreational vehicle relative to the electrified vehicle.

5. The system as recited in claim 1 , comprising a charge cable that is connectable to a first charge port assembly of the electrified vehicle and a second charge port assembly of the electrified recreational vehicle during a bidirectional energy transfer event.

6. The system as recited in claim 1 , wherein the control module is further programmed to collect data from the electrified recreational vehicle during an off-roading event.

7. The system as recited in claim 6 , wherein the data includes location data and battery capacity/range data.

8. The system as recited in claim 1 , wherein the control module is a component of the electrified vehicle.

9. The system as recited in claim 1 , wherein the control module is further programmed to receive a charging profile from the electrified recreational vehicle.

10. The system as recited in claim 1 , wherein the control module is further programmed to command an alert system of the electrified vehicle to emit audible instructions for guiding a connection of the electrified vehicle to the electrified recreational vehicle prior to performing a bidirectional energy transfer event.

11. The system as recited in claim 1 , wherein the control module is further programmed to communicate the charging alert notification to at least one additional electrified recreational vehicle.

12. The system as recited in claim 1 , wherein the control module is further programmed to communicate driving instructions to the electrified recreational vehicle when the electrified recreational vehicle has an insufficient amount of remaining travel range to return to the electrified vehicle during an off-roading event.

13. The system as recited in claim 1 , wherein the electrified vehicle is a pickup truck, and the electrified recreational vehicle is an all-terrain vehicle, a utility vehicle, a motorcycle, or a snowmobile.

14. An electrified vehicle, comprising:
a telecommunications module; and
a control module operably connected to the telecommunications module, wherein the control module is programmed to:
collect data from an electrified recreational vehicle during an off-roading event;
predict a likelihood of a no start/stranded condition of the electrified recreational vehicle based on the data; and
in response to predicting the no start/stranded condition is likely, command the telecommunications module to communicate a charging alert notification to the electrified recreational vehicle.

15. The electrified vehicle as recited in claim 14 , wherein the data includes location data and battery capacity/travel range data.

16. The electrified vehicle as recited in claim 14 , wherein the no start/stranded condition is predicted as being likely when a relative distance between the electrified recreational vehicle and the electrified vehicle is greater than a predefined percentage of an available travel range of the electrified recreational vehicle.

17. The electrified vehicle as recited in claim 14 , wherein the no start/stranded condition is predicted as being likely when a remaining state of charge of a traction battery pack of the electrified recreational vehicle is less than or equal to a predefined percentage of an amount of charge that was required to reach a current location of the electrified recreational vehicle.

18. The electrified vehicle as recited in claim 14 , wherein the control module is further programmed to communicate driving instructions to the electrified recreational vehicle when the electrified recreational vehicle has an insufficient amount of remaining travel range to return to the electrified vehicle during the off-roading event.

19. The electrified vehicle as recited in claim 14 , wherein the charging alert notification indicates a need to return to the electrified vehicle for charging to a user of the electrified recreational vehicle.

20. A method, comprising:
collecting data from an electrified recreational vehicle during an off-roading event;
predicting a likelihood of a no start/stranded condition of the electrified recreational vehicle based on the data; and
in response to predicting that the no start/stranded condition is likely, communicating a charging alert notification to the electrified recreational vehicle.
