Abstract

This disclosure describes exemplary electrified vehicle charging systems for charging battery packs. An exemplary charging system includes a visual indicator (e.g., pictogram, text, or both) located on-board the vehicle that can be automatically illuminated once the battery pack has been charged to a predefined minimum state of charge (SOC) threshold. The visual indicator communicates charging status messages to other electrified vehicle users, and once illuminated, provides an intuitive indication to the other vehicle users that the electrified vehicle that is currently on-plug has received a sufficient amount of charge and therefore may be unplugged from a charging station. The visual indicator therefore facilitates a courtesy hand-off of charging station components from one electrified vehicle user to another. In addition to or instead of the on-board visual indicator, the charging system may facilitate courtesy hand-offs between electrified vehicle users by broadcasting charging status messages through one or more mobile applications.

Claims

1. A charging system for an electrified vehicle, comprising:

a battery pack;

a charging component in charging connection with the battery pack; and

a control module located on-board the electrified vehicle and being configured to;

receive an input from a mobile device associated with the electrified vehicle indicating that a charge hand-off feature is enabled; and

command the mobile device to broadcast a charging status message that facilitates a courtesy hand-off of a charging station component to another electrified vehicle user,

wherein the charging status message is broadcast from the mobile device to a second, different mobile device.

2. The charging system as recited in claim 1, wherein the charging component is a vehicle inlet assembly.

3. The charging system as recited in claim 1, wherein the mobile device is configured through an application to input a predefined minimum state of charge (SOC) threshold associated with the charge hand-off feature.

4. The charging system as recited in claim 3, wherein the charging status message indicates that the predefined minimum SOC has been reached and thus the courtesy hand-off can occur.

5. The charging system as recited in claim 3, wherein the charging status message indicates an amount of time remaining before reaching the predefined minimum SOC.

6. The charging system as recited in claim 1, comprising a visual indicator on the charging component.

7. The charging system as recited in claim 6, wherein the control module is configured to illuminate the visual indicator in response to reaching a predefined state of charge (SOC) threshold of the battery pack.

8. The charging system as recited in claim 1, comprising a communication system having a first transceiver configured to wirelessly communicate with a second transceiver of the mobile device.

9. The charging system as recited in claim 1, wherein the charging station component is a charge cord of a public charging station.

10. The charging system as recited in claim 1, wherein the mobile device includes an application having a user interface configured to enter the input and to set a predefined minimum SOC threshold that is associated with the charge hand-off feature.

11. The charging system as recited in claim 10, wherein the user interface includes a first toggle for entering the input and a second toggle for setting the predefined minimum SOC threshold.

12. The charging system as recited in claim 1, wherein the charging component is a vehicle inlet assembly equipped with a pictogram, and the control module is configured to illuminate the pictogram in response to reaching a predefined state of charge (SOC) threshold of the battery pack.

13. A charging system for an electrified vehicle, comprising:

a battery pack;

a charging component in charging connection with the battery pack; and

a control module configured to;

receive an input from a mobile device associated with the electrified vehicle indicating that a charge hand-off feature is enabled; and

command the mobile device to broadcast a charging status message that facilitates a courtesy hand-off of a charging station component to another electrified vehicle user,

wherein the charging status message is broadcast from the mobile device to at least one other mobile device associated with the another electrified vehicle user.

14. A method, comprising:

receiving, at an on-board control module of an electrified vehicle, an input from a mobile device associated with the electrified vehicle indicating that a charge hand-off feature is enabled; and

commanding, via the control module, the mobile device to broadcast a charging status message that facilitates a courtesy hand-off of a charging station component to another electrified vehicle user,

wherein the charging status message is broadcast from the mobile device to at least one other mobile device associated with the another electrified vehicle user.

15. The method as recited in claim 14, comprising illuminating a visual indicator of a charging component located on-board the electrified vehicle in response to reaching a predefined minimum state of charge (SOC) threshold when charging a battery pack of the electrified vehicle.

16. The method as recited in claim 14, wherein the mobile device is configured through an application to input a predefined minimum state of charge (SOC) threshold associated with the charge hand-off feature.

17. The method as recited in claim 16, wherein the charging status message indicates that the predefined minimum SOC has been reached and thus the courtesy hand-off can occur.

18. The method as recited in claim 16, wherein the charging status message indicates an amount of time remaining before reaching the predefined minimum SOC.
