Abstract

Electric vehicles indicate charge levels in different ways. A lighting control module is communicatively is configured to illuminate an exterior light of an electric vehicle to indicate a charge status of a battery for the electric vehicle. The charge status is indicated based on varying an intensity of the exterior light, based on illuminating a subset of the exterior lights, and/or based on an animation. The display of the charge indicator varies based on a location of the vehicle, the presence of a person in proximity to the vehicle, and/or a charger connected to the vehicle.

First claim

What is claimed is:

1 . A system, comprising:
a light control module configured to indicate charging of a battery of a vehicle with a first side lamp and a second side lamp of an exterior of the vehicle, wherein the light control module is configured, in response to determining that the battery is receiving an inflow of current, to:
illuminate a portion of the first side lamp and a portion of the second side lamp based on an initial illuminated size;
progressively increase the sizes of the illuminated portions of the first side lamp and the second side lamp over time inwardly in a direction from an outside perimeter of the first side lamp and the second side lamp toward a center between the first side lamp and the second side lamp; and
decrease, after the first side lamp and the second side lamp are a maximum size of the illuminated portions and while the battery is receiving an inflow of current, the sizes of the illuminated portions of the first side lamp and the second side lamp to the initial illuminated size.

2 . The system of claim 1 , wherein progressively increasing the sizes of the illuminated portions inwardly from the outside perimeter provides an animation the vehicle is currently receiving a charge.

3 . The system of claim 1 , wherein the first side lamp and the second side lamp comprise a set of light emitting diodes (LEDs), and wherein illuminating the portions of the first side lamp and the second side lamp comprises illuminating certain LEDs inwardly from the outside perimeter to indicate charging of the vehicle.

4 . The system of claim 1 , further comprising a light bar that progressively increases the sizes of the illuminated portions over time.

5 . The system of claim 1 , wherein the first side lamp is located on a front left side of the vehicle, and wherein the second side lamp is located on a front right side of the vehicle.

6 . The system of claim 1 , wherein the first side lamp and the second side lamp comprise a plurality of segments, and wherein the light control module is further configured to illuminate a subset of the plurality of segments based on a charge level of the vehicle.

7 . A method, comprising:
indicating charging of a battery of a vehicle through a first side lamp and a second side lamp of an exterior of the vehicle, in response to determining that the battery is receiving an inflow of current, by:
illuminating a portion of the first side lamp and a portion of the second side lamp based on an initial illuminated size;
progressively increasing the sizes of the illuminated portions of the first side lamp and the second side lamp over time inwardly in a direction from an outside perimeter of the first side lamp and the second side lamp toward a center between the first side lamp and the second side lamp; and
decrease, after the first side lamp and the second side lamp are a maximum size of the illuminated portions and while the battery is receiving the inflow of current, the sizes of the illuminated portions of the first side lamp and the second side lamp to the initial illuminated size.

8 . The method of claim 7 , wherein progressively increasing the sizes of the illuminated portions inwardly from the outside perimeter provides an animation the vehicle is currently receiving a charge.

9 . The method of claim 7 , wherein the first side lamp and the second side lamp comprise a set of light emitting diodes (LEDs), and wherein illuminating the portions of the first side lamp and the second side lamp comprises illuminating certain LEDs to indicate charging of the vehicle.

10 . The method of claim 7 , wherein the first side lamp is located on a front left side of the vehicle, and wherein the second side lamp is located on a front right side of the vehicle.

11 . The method of claim 7 , further comprising illuminating a subset of a plurality of segments corresponding to the first side lamp and the second side lamp based on a charge level of the vehicle.

12 . A vehicle, comprising:
a battery; a first side lamp and a second side lamp on an exterior of the vehicle; and a light control module configured to indicate charging of the battery of the vehicle with the first side lamp and the second side lamp, wherein the light control module is configured, in response to determining that the battery is receiving an inflow of current, to:
illuminate a portion of the first side lamp and a portion of the second side lamp based on an initial illuminated size;
progressively increase the sizes of the illuminated portions of the first side lamp and the second side lamp over time inwardly in a direction from an outside perimeter of the first side lamp and the second side lamp toward a center between the first side lamp and the second side lamp; and
decrease, after the first side lamp and the second side lamp are a maximum size of the illuminated portions and while the battery is receiving the inflow of current, the sizes of the illuminated portions of the first side lamp and the second side lamp to the initial illuminated size.

13 . The vehicle of claim 12 , wherein the progressively increasing the sizes of the illuminated portions inwardly from the outside perimeter provides an animation the vehicle is currently receiving a charge.

14 . The vehicle of claim 12 , wherein the first side lamp and the second side lamp comprise a set of light emitting diodes (LEDs), and wherein illuminating the portions of the first side lamp and the second side lamp comprises illuminating certain LEDs inwardly from the outside perimeter to indicate charging of the vehicle.

15 . The vehicle of claim 12 , the light control module further configured to repeat a cycle of progressively increasing the sizes of the illuminated portions of the first side lamp and the second side lamp.

16 . The vehicle of claim 12 , wherein the first side lamp is located on a front left side of the vehicle, and wherein the second side lamp is located on a front right side of the vehicle.

17 . The vehicle of claim 12 , wherein the first side lamp and the second side lamp comprise a plurality of segments, and wherein the light control module is further configured to illuminate a subset of the plurality of segments based on a charge level of the vehicle.
