Automatically identifying an intended electric vehicle supply equipment
Automatically identifying an electric vehicle supply equipment (EVSE) is described. A receiver device receives wireless signals from EVSEs, where each wireless signal includes an identifier that is associated with the one of the EVSEs from which that wireless signal is received. The receiver device records signal strength values of the wireless signals and determines, based on the recorded signal strength values, which of the EVSEs is closest to the receiver device. The receiver device initiates a request for an action at the EVSE determined to be closest to the receiver device.
1. A method for automatically identifying an electric vehicle supply equipment (EVSE), comprising:
receiving, at a receiver device, a plurality of wireless signals from a plurality of EVSEs respectively, wherein each of the plurality of wireless signals includes an identifier that is associated with the one of the plurality of EVSEs from which that wireless signal is received;
recording signal strength values of the plurality of wireless signals;
determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device; and
initiating a request for an action at the EVSE determined to be closest to the receiver device.
2. The method of claim 1 , wherein the received plurality of wireless signals are Bluetooth Low Energy (BLE) beacon signals.
3. The method of claim 1 , wherein the receiver device is included within an electric vehicle, and wherein determining which of the plurality of EVSEs is closest to the receiver device is performed by an application executing within the electric vehicle.
4. The method of claim 3 , wherein determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device is performed responsive to detecting that a door of the electric vehicle has been opened or the electric vehicle has been put into park.
5. The method of claim 1 , wherein the receiver device is a smartphone, and wherein determining which of the plurality of EVSEs is closest to the receiver device is performed by an application executing within the smartphone.
6. The method of claim 5 , wherein determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device is performed responsive to detecting that the smartphone has transitioned from driving mode to non-driving mode.
7. The method of claim 1 , wherein initiating the request for the action at the determined EVSE includes transmitting an EVSE identifier that is associated with the EVSE that is determined to be closest to the receiver device to a server to perform an authorization procedure.
8. The method of claim 7 , wherein initiating the request for an action at the determined EVSE includes transmitting an identifier associated with an operator of an electric vehicle or an identifier associated with the electric vehicle to the server.
9. A method, comprising:
broadcasting, from a plurality of electric vehicle supply equipments (EVSEs), a plurality of wireless signals, wherein each wireless signal from one of the plurality of EVSEs includes an identifier that is uniquely associated with that one of the plurality of EVSEs, the plurality of wireless signals being capable of being used by an application of a receiver device as a basis to automatically identify which of the plurality of EVSEs is closest to the receiver device;
receiving, at one of the plurality of EVSEs, a communication from a server that indicates to enable charging;
unlocking a charging port at that one of the plurality of EVSEs responsive to the received communication; and
enabling charging service through the unlocked charging port.
10. The method of claim 9 , wherein the wireless signals are each a Bluetooth Low Energy (BLE) beacon signal.
11. The method of claim 9 , further comprising:
showing a visual indicator on the one of the plurality of EVSEs that signifies that the one of the plurality of EVSEs has been automatically identified.
12. The method of claim 9 , wherein prior to broadcasting the wireless signals, each of the plurality of EVSEs determining that it is available for charging an electric vehicle.
13. The method of claim 12 , wherein determining that the EVSE is available for charging an electric vehicle includes determining that the EVSE is not currently charging an electric vehicle.
14. A non-transitory machine-readable storage medium that provides instructions that, if executed by a processor, will cause said processor to perform operations for automatically identifying an electric vehicle supply equipment (EVSE) comprising:
receiving, at a receiver device, a plurality of wireless signals from a plurality of EVSEs respectively, wherein each of the plurality of wireless signals includes an identifier that is associated with the one of the plurality of EVSEs from which that wireless signal is received;
recording signal strength values of the plurality of wireless signals;
determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device; and
initiating a request for an action at the EVSE determined to be closest to the receiver device.
15. The non-transitory machine-readable storage medium of claim 14 , wherein the received plurality of wireless signals are Bluetooth Low Energy (BLE) beacon signals.
16. The non-transitory machine-readable storage medium of claim 14 , wherein the receiver device is included within an electric vehicle, and wherein determining which of the plurality of EVSEs is closest to the receiver device is performed by an application executing within the electric vehicle.
17. The non-transitory machine-readable storage medium of claim 16 , wherein determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device is performed responsive to detecting that a door of the electric vehicle has been opened or the electric vehicle has been put into park.
18. The non-transitory machine-readable storage medium of claim 14 , wherein the receiver device is a smartphone, and wherein determining which of the plurality of EVSEs is closest to the receiver device is performed by an application executing within the smartphone.
19. The non-transitory machine-readable storage medium of claim 18 , wherein determining, based on the recorded signal strength values of the plurality of wireless signals, which of the plurality of EVSEs is closest to the receiver device is performed responsive to detecting that the smartphone has transitioned from driving mode to non-driving mode.
20. The non-transitory machine-readable storage medium of claim 14 , wherein initiating the request for the action at the determined EVSE includes transmitting an EVSE identifier that is associated with the EVSE that is determined to be closest to the receiver device to a server to perform an authorization procedure.
