Abstract

A communication method to discharge energy is enabled. For example, a vehicle can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise a connection component that, based on receiving a connection from a first vehicle, establishes a communication link with the first vehicle, a communication component that, based on receiving the connection, receives a charge sharing request message, from the first vehicle, comprising charge transfer data, and a charge sharing determination component that, based on a charge sharing request message, determines a type of charge sharing request extracted from the charge sharing request message.

based on the type of charge sharing request and a first criterion, identifies one or more other vehicles of the at least three vehicles that satisfy the type of charge sharing request and the first criterion;

based on a second criterion, selects a second vehicle of the one or more other vehicles to perform a vehicle-to-vehicle charging of the first vehicle; and

initiates the vehicle-to-vehicle charging from the second vehicle to the first vehicle, comprising routing a charge from a second bidirectional charging port of the at least three bidirectional charging ports having the charging connection with the second vehicle and a first bidirectional charging port of the at least three bidirectional charging ports having the charging connection with the first vehicle.

3 . The charging station of claim 2 , wherein the charge sharing indicator comprises a discharge indicator and the charge data comprises a charge value.

4 . The charging station of claim 1 , wherein the at least one of the computer executable components further:

requests, from the second vehicle, authorization to initiate the vehicle-to-vehicle charging from the second vehicle to the first vehicle.

5 . The charging station of claim 1 , wherein computer the first criterion comprises an amount of charge remaining in a respective battery of the one or more other vehicles satisfying a defined threshold.

6 . The charging station of claim 1 , wherein the second criterion is based on at least one of a safety criterion, a payment criterion, or a user confirmation criterion.

7 . The charging station of claim 1 , wherein the at least one of the computer executable components further:

based on the first criterion, selects a third vehicle of the one or more other vehicles to perform the vehicle-to-vehicle charging of the first vehicle; and

concurrent with the vehicle-to-vehicle charging from the second vehicle to the first vehicle, initiates the vehicle-to-vehicle charging from the third vehicle to the first vehicle, comprising routing another charge from a third bidirectional charging port of the at least three bidirectional charging ports having the charging connection with the third vehicle and the first bidirectional charging port having the charging connection with the first vehicle.

8 . A method, comprising:

performing, by a charging station, vehicle-to-vehicle charging, wherein the charging station comprises at least three bidirectional charging ports, wherein each of the at least three bidirectional charging ports are routable to all others of the at least three bidirectional charging ports for charging connections therebetween, and wherein the performing the vehicle-to-vehicle charging comprises:

based on receiving respective charging connections to the at least three bidirectional charging ports from at least three vehicles, establishing, by the charging station, respective communication links with the at least three vehicles;

receiving, by the charging station, a charge sharing request message from a first vehicle of the at least three vehicles, wherein the charge sharing request message comprises charge transfer data specifying a type of charge sharing request;

based on the type of charge sharing request and a first criterion, identifying, by the charging station, one or more other vehicles of the at least three vehicles that satisfy the type of charge sharing request and the first criterion;

based on a second criterion, selecting, by the charging station, a second vehicle of the one or more other vehicles to perform the vehicle-to-vehicle charging of the first vehicle; and

initiating, by the charging station, the vehicle-to-vehicle charging from the second vehicle to the first vehicle, comprising routing a charge from a second bidirectional charging port of the at least three bidirectional charging ports having the charging connection with the second vehicle and a first bidirectional charging port of the at least three bidirectional charging ports having the charging connection with the first vehicle.

9 . The method of claim 8 , wherein the charge transfer data comprises a discharge indicator, charge data, a session time value, a price offer value, and a payment method.

10 . The method of claim 8 , wherein the charge transfer data comprises a charge sharing indicator, charge data, a session time value, a price offer value, and a payment method.

11 . The method of claim 8 , wherein the method further comprises:

requesting, by the charging station, from the second vehicle, authorization to initiate the vehicle-to-vehicle charging from the second vehicle to the first vehicle.

12 . The method of claim 8 , wherein the first criterion comprises an amount of charge remaining in a respective battery of the one or more other vehicles satisfying a defined threshold.

13 . The method of claim 8 , wherein the second criterion is based on at least one of a safety criterion, a payment criterion, or a user confirmation criterion.

14 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, cause a charging station to perform operations comprising:

performing, by the charging station, vehicle-to-vehicle charging, wherein the charging station comprises at least three bidirectional charging ports, wherein each of the at least three bidirectional charging ports are routable to all others of the at least three bidirectional charging ports for charging connections therebetween, and wherein the performing the vehicle-to-vehicle charging comprises:

based on receiving respective charging connections to the at least three bidirectional charging ports from at least three vehicles, establishing, by the charging station, respective communication links with the at least three vehicles;

receiving, by the charging station, a charge sharing request message from a first vehicle of the at least three vehicles, wherein the charge sharing request message comprises charge transfer data specifying a type of charge sharing request;

based on the type of charge sharing request and a first criterion, identifying, by the charging station, one or more other vehicles of the at least three vehicles that satisfy the type of charge sharing request and the first criterion;

based on a second criterion, selecting, by the charging station, a second vehicle of the one or more other vehicles to perform the vehicle-to-vehicle charging of the first vehicle; and
