Abstract

The present disclosure relates to a system and a method for electric vehicle charging. The system may perform the method to: receive a request for charging station recommendation from a client terminal; determine at least one charging station within a preset distance range of the client terminal; determine an evaluation for each of the at least one charging station based on one or more evaluation parameters; and transmitting, by the first computing device, the evaluation of the each of the at least one charging station and an identifier of the each of the at least one charging station to the client terminal.

First claim

We claim:

1. A method implemented on one or more computing devices for charging an electric vehicle, each of the one or more computing devices having at least one processor, at least one storage device and a data exchange port communicatively connected to a network, the one or more computing devices including at least one of a first computing device for charging station recommendation or a second computing device for charging control, the method comprising:
receiving, by the first computing device, a request for charging station recommendation from a client terminal;
determining, by the first computing device, at least one charging station within a preset distance range of the client terminal;
determining, by the first computing device, an evaluation for each of the at least one charging station based on one or more evaluation parameters, wherein the one or more evaluation parameters include at least one of:
a price discount provided by the each of the at least one charging station, a distance between the each of the at least one charging station and the client terminal, a preset recommendation value for the each of the at least one charging station, or a historical evaluation of the each of the at least one charging station;
transmitting, by the first computing device, the evaluation of the each of the at least one charging station and an identifier of the each of the at least one charging station to the client terminal;
receiving, by the second computing device, a charging request and an associating request for connecting the client terminal and the second computing device from a target charging pile at one of the at least one charging station;
determining, by the second computing device, charging information for charging an electric vehicle associated with the client terminal based on the charging request;
establishing, by the second computing device, a connection between the second computing device and the client terminal based on the associating request;
sending, by the second computing device, the charging information to the target charging pile for charging the electric vehicle based on the charging information; and
sending, by the second computing device, a charging signal to the target charging pile causing the target charging pile to charge the electric vehicle.

2. The method of claim 1 , wherein the determining, by the first computing device, an evaluation for each of the at least one charging station includes:
obtaining one or more preset weight values corresponding to the one or more evaluation parameters, respectively;
estimating a weighted sum of the one or more evaluation parameters based on the one or more preset weight values; and
designating the weighted sum of the one or more evaluation parameters as the evaluation of the each of the at least one charging station.

3. The method of claim 2 , wherein the one or more preset weight values include at least one of:
a first preset weight value corresponding to the price discount provided by the each of the at least one charging station being 40%,
a second preset weight value corresponding to the distance between the each of the at least one charging station and the client terminal being 35%,
a third preset weight value corresponding to the preset recommendation value of the each of the at least one charging station being 20%, or
the fourth preset weight value corresponding to the historical evaluation value of the each of the at least one charging station being 5%.

4. The method of claim 1 , further comprising:
for each of the at least one charging station,
determining, by the first computing device, the preset recommendation value based on one or more recommendation parameters, wherein the one or more recommendation parameters include at least one of:
a number of charging piles at the each of the at least one charging station,
a real-time parking fee at the each of the at least one charging station, or
a unit charging price associated with the each of the at least one charging station.

5. The method of claim 4 , wherein the determining the preset recommendation value includes:
obtaining one or more preset percentages corresponding to one of the one or more recommendation parameters, respectively; and
determining the preset recommendation value based on the one or more preset percentages, wherein the preset recommendation value is equal to a sum of the one or more recommendation parameters multiplying the corresponding preset percentage, respectively.

6. The method of claim 5 , wherein the one or more preset percentages include at least one of:
a first preset percentage corresponding to the number of charging piles at the each of the charging station being 45%,
a second preset percentage corresponding to the real-time parking fee at the each of the at least one charging station being 35%, or
a third preset percentage corresponding to the charging unit price associated with the each of the at least one charging station being 20%.

7. The method of claim 1 , wherein the transmitting the evaluation of each of the at least one charging station and an identifier of each of the at least one charging station to the client terminal includes:
sorting the at least one charging station in a descending order according to the evaluation of the at least one charging station; and
sending the evaluation of each of the sorted at least one charging station and the identifier of each of the sorted at least one charging station to the client terminal for display.

8. The method of claim 1 , wherein the transmitting the evaluation of each of the at least one charging station and an identifier of each of the at least one charging station to the client terminal includes:
determining whether the evaluation of the each of the at least one charging station is greater than or equal to a preset threshold; and
sending the identifier of the each of the at least one charging station to the client terminal for display in response to a determination that the evaluation is greater than or equal to the preset threshold.

9. The method of claim 1 , further comprising:
obtaining, by the second computing device, a current charging status of the electric vehicle from the target charging pile; and
sending, by the second computing device, the current charging status to the client terminal through the connection between the client terminal and the second computing device.

10. The method of claim 1 , further comprising:
determining, by the second computing device, whether the charging for the electric vehicle is completed;
in response to a determination that the charging for the electric vehicle is completed, determining, by the second computing device, a charging fee corresponding to the charging information;
sending, by the second computing device, the charging fee to the client terminal; and
deducting, by the second computing device, the charging fee from an electronic financial account associated with the client terminal upon receiving a payment confirmation for the charging fee from the client terminal.

11. A method for charging control of an electric vehicle implemented on a charging management device having at least one processor, at least one storage device and a data exchange port communicatively connected to a network, the method comprising:
receiving, by the at least one processor, a charging request and an associating request for connecting a client terminal and the charging management device from a charging pile;
determining, by the at least one processor, charging information for charging an electric vehicle associated with the client terminal based on the charging request;
establishing, by the at least one pro
