Estimating vehicle state of charge using Bluetooth identification
Techniques for estimating a vehicle state of charge (“SoC”) are disclosed. A computing device may determine a first instance of connectivity between the computing device and an electric vehicle and determine a first location of the computing device associated with the first instance of connectivity. The computing device may detect completion of a first trip of the electric vehicle, wherein the first trip reflects movement of the electric vehicle from the first location to a second location, and determine a first distance traveled by the electric vehicle during the first trip based on the first location and the second location. The computing device may select the electric vehicle for charging using the determined first instance of connectivity between the computing device and the electric vehicle, estimate a SoC of the selected electric vehicle using the determined first distance, and transmit the estimated SoC to a charging station.
1. A computing device for charging an electric vehicle based on an estimated state of charge of the electric vehicle, comprising:
a network interface to provide network connectivity over a communication network;
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the computing device to:
receive, from a mobile device, location data of the mobile device reflecting a distance traveled by an electric vehicle during one or more instances of connectivity between the electric vehicle and the mobile device;
receive, from the mobile device, a user input indicating selection corresponding to a media access control (MAC) address of the electric vehicle;
determine an estimated state of charge of the electric vehicle based on the received location data;
receive, from the mobile device, a current location of the mobile device that reflects a current location of the electric vehicle;
determine that the current location of the mobile device is within a predetermined distance of a known location of a charging station;
transmit the estimated state of charge to the charging station; and
authorize the charging station to charge the electric vehicle using the estimated state of charge.
2. The computing device of claim 1 , wherein a first instance of connectivity occurs when a driver or occupant of the electric vehicle is located within a predetermined distance of the vehicle.
3. The computing device of claim 1 , wherein the electric vehicle is automatically selected for charging due to a match between the MAC address of the electric vehicle and a stored MAC address.
4. The computing device of claim 1 , wherein the selecting of the electric vehicle for charging includes detecting an input via a user interface of the computing device that indicates a selection of the electric vehicle from a driver profile.
5. The computing device of claim 1 , wherein the computing device determines the current location using global positioning system (GPS) circuitry of the computing device.
6. The computing device of claim 1 , wherein the computing device determines the current location using GPS data from a charging station located within a predetermined distance of the computing device.
7. The computing device of claim 1 , wherein the computing device determines the current location using triangulation based on two or more wireless communication network access points for which respective locations are known.
