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 receiver device, comprising:
a processing system and a non-transitory storage machine-readable storage medium that provides instructions that, when executed by the processing system, cause the receiver device to perform operations including:
receiving a plurality of wireless signals from a plurality of electric vehicle supply equipments (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 receiver device of claim 1 , wherein the received plurality of wireless signals are Bluetooth Low Energy (BLE) beacon signals.
3. The receiver device 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 receiver device 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 receiver device 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 receiver device 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 receiver device 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 receiver device 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. The receiver device 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 initiate a charging port unlocking procedure.
10. The receiver device of claim 9 , 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.
11. A system, comprising:
a plurality of electric vehicle supply equipment (EVSEs) that each include:
a beacon to broadcast a plurality of wireless signals, wherein each wireless signal from a particular one of the plurality of EVSEs includes an identifier that is uniquely associated with that one of the plurality of EVSEs, wherein the plurality of wireless signals are 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;
a transceiver to receive a communication from a server that indicates to enable charging; and
a charging port that is unlocked responsive to the transceiver receiving the communication from the server that indicates to enable charging;
wherein charging service is enabled through the unlocked charging port.
12. The system of claim 11 , wherein the wireless signals are each a Bluetooth Low Energy (BLE) beacon signal.
13. The system of claim 11 , further comprising:
a visual indicator that signifies whether that EVSE has been automatically identified.
14. The system of claim 11 , further comprising:
an audio indicator that signifies whether that EVSE has been automatically identified.
15. The system of claim 11 , wherein each EVSE is configured to broadcast the plurality of wireless signals after determining that the EVSE is available for charging an electric vehicle.
