Charging method, apparatus, and system

1 . A charging method comprising:

displaying a charging reservation interface, wherein the charging reservation interface comprises a map that displays one or more available charging points;

receiving an operation on the charging reservation interface;

obtaining charging reservation information of an electric vehicle in response to the operation, wherein the charging reservation information comprises a charging location of the electric vehicle, and wherein the charging location is a location of a target charging point in the one or more available charging points;

obtaining target unlocking information of a charging port cover of the electric vehicle, wherein the target unlocking information is a randomly generated character string, or comprises an account registered with a vehicle management server of the electric vehicle and a password used to log in to the account, wherein obtaining the target unlocking information comprises:

receiving, (a) from the electric vehicle, the target unlocking information of the charging port cover in response to an unlocking information generation request; or

receiving, (b) from a mobile terminal, the unlocking information generation request at a vehicle management server of the electric vehicle, and receiving the target unlocking information that is of the charging port cover of the electric vehicle and that is from the vehicle management server;

after receiving (a) or (b), generating a charging reservation request based on the charging reservation information and the target unlocking information; and

sending the charging reservation request to a charging server comprising a computing system, wherein the charging reservation request instructs the charging server to schedule a mobile charging vehicle at the charging location based on the charging reservation information and to send the target unlocking information to an unlocking device on the mobile charging vehicle after detecting the mobile charging vehicle at the charging location.

2 . The charging method of claim 1 , further comprising:

receiving, by the electric vehicle, an unlocking request from the unlocking device; and

unlocking, by the electric vehicle, the charging port cover when the unlocking request meets an unlocking condition, wherein the unlocking condition includes that unlocking information carried in the unlocking request matches the target unlocking information.

3 . The charging method of claim 2 , wherein the charging reservation information further comprises a valid time period of the target unlocking information, and wherein the unlocking condition further includes a moment at which the unlocking request is received is within the valid time period.

4 . The charging method of claim 2 , further comprising receiving, by the electric vehicle, an unlocking request after the mobile charging vehicle is at the charging location.

5 . The charging method of claim 1 , wherein the charging reservation information further comprises at least one of a charging time period, vehicle information, or charging requirement information.

6 . The charging method of claim 1 , further comprising displaying the charging reservation interface with the map that displays a location of a mobile charging vehicle near a current location of the electric vehicle.

7 . A charging method, comprising:

receiving, from an electric vehicle or a vehicle management server, a charging reservation request, and receiving, from the vehicle management server, target unlocking information of a charging port cover of the electric vehicle, wherein the charging reservation request comprises charging reservation information of the electric vehicle and the target unlocking information of the charging port cover of the electric vehicle, wherein the target unlocking information is a randomly generated character string, or comprises an account registered with the vehicle management server of the electric vehicle and a password for the account, wherein the charging reservation information comprises a charging location of the electric vehicle, and wherein the charging location is a location of a target charging point of one or more available charging points;

scheduling, based on the charging reservation information, a mobile charging vehicle at the charging location for charging the electric vehicle;

sending the charging location to the mobile charging vehicle; and

sending, by a computing system, the target unlocking information to an unlocking device on the mobile charging vehicle after detecting the mobile charging vehicle at the charging location.

8 . The charging method of claim 7 , wherein the target unlocking information is based on an unlocking information generation request.

9 . The charging method of claim 8 , wherein the charging reservation information further comprises a valid time period of the target unlocking information.

10 . The charging method of claim 7 , wherein the charging reservation information further comprises a charging time period.

11 . The charging method of claim 7 , further comprising receiving, from the mobile charging vehicle, the unlocking request.

12 . The charging method of claim 11 , wherein the unlocking request includes an identifier of the electric vehicle and unlocking information.

13 . The charging method of claim 12 , further comprising sending, to the electric vehicle, an unlocking instruction instructing the electric vehicle to unlock the charging port cover.

14 . A charging apparatus, comprising:

a computer-readable storage medium configured to store instructions; and

a processor coupled to the computer-readable storage medium and configured to execute the instructions to cause the charging apparatus to:

receive, from an electric vehicle or a vehicle management server, a charging reservation request, and receive, from the vehicle management server, target unlocking information of a charging port cover of the electric vehicle, wherein the charging reservation request comprises charging reservation information of the electric vehicle and the target unlocking information of the charging port cover of the electric vehicle, wherein the target unlocking information is a randomly generated character string, or comprises an account registered with the vehicle management server of the electric vehicle and a password for the account, and wherein the charging reservation information comprises at least a charging location of the electric vehicle;

schedule, based on the charging reservation information, a mobile charging vehicle at the charging location for charging the electric vehicle;

send the charging location to the mobile charging vehicle; and

send the target unlocking information to an unlocking device on the mobile charging vehicle after detecting the mobile charging vehicle at the charging location.

15 . The charging apparatus of claim 14 , wherein the target unlocking information is based on an unlocking information generation request.

16 . The charging apparatus of claim 15 , wherein the charging reservation information further comprises a valid time period of the target unlocking information.

17 . The charging apparatus of claim 14 , wherein the charging reservation information further comprises a charging time period.

18 . The charging apparatus of claim 14 , wherein the instructions, when executed by the processor, further cause the charging apparatus to display a charging reservation interface, wherein the charging reservation interface comprises a map that displays one or more available charging points.

19 . The charging apparatus of claim 18 , wherein the instructions, when executed by the processor, further cause the charging apparatus to receive an operation on the charging reservation interface.
