The embodiment of the invention relates to the provided charging service method, which improves the use experience effect of users, increases the service capability of the mobile charging service, not only can fully utilize the electric energy resource of a charging vehicle, but also can ensure the flexibility of the mobile charging service, and better meets the requirements of the users.
Fig. 1 is a schematic flow chart of a charging service method according to an embodiment of the present invention, and a technical solution of the present invention is described with reference to fig. 1 as a specific embodiment.
Step 101, a background server receives charging demand information sent by a user terminal.
Specifically, the background server is a management platform server of the charging vehicles, and is used for managing all the charging vehicles, performing real-time statistics and updating on the task state, the current position, the remaining capacity, the route planning path and other related data information of the charging vehicles, performing task assignment according to the charging requirements of the users, designating the proper charging vehicles, and fully utilizing the charging vehicle resources. It should be understood that the "background server" may be a server integrating functions of vehicle management service, map navigation service, and the like, or may be a plurality of separate servers respectively including a vehicle management server, a map data server, and the like. Herein, the background servers are collectively referred to as background servers, and are not separately described, but it is not meant that only one server is included in the technical solution of the present invention.
The user terminal in the embodiment of the invention refers to a terminal device used by a user, and is used for sending charging demand information according to the charging demand of the user, requesting a charging service to a background server, and correspondingly adjusting according to charging related information of a single order fed back by a charging vehicle so as to meet the actual demand of the user.
The device to be charged in the embodiment of the invention is widely understood, and can be a pure electric vehicle or an electric bicycle, and can also be other devices needing charging service.
The charging demand information includes user information of the user terminal, demand electric quantity, charging position, charging time and information of a preselected charging type, specifically, the demand electric quantity refers to an electric quantity demand set by the user when the user requests a charging service, and the demand electric quantity here can be specific data, namely a specific electric quantity value, or fuzzy data, for example, the user only gives the battery capacity of the vehicle; the charging position refers to the position of the equipment to be charged of the charging service required by the user; the charging time is the reserved time for executing the charging task, and can be the current time or a certain future time; the pre-selection charging type comprises a fast charging mode and a slow charging mode, each charging vehicle can provide the two charging modes and is selected according to the actual requirements of the user, if the user needs to finish charging in the shortest time, the user can be recommended to select the fast charging mode, and correspondingly, if the user does not have the requirement on the charging time, the slow charging mode can be preferred.
And 102, the background server performs charging task allocation processing according to the charging demand information to generate the charging vehicle scheduling information.
Specifically, the charging vehicle scheduling information includes the vehicle ID of the assigned charging vehicle, the charging demand information, the planned driving route, and the departure time information. The background server selects and dispatches the vehicles according to the user requirements through the state information of the charging vehicles recorded in the charging vehicle management list, and further, the background server performs fuzzy calculation on the information of the charging vehicles according to the information of the charging positions and the charging time to obtain the alternative charging vehicles which can reach the charging positions in the charging time.
In a specific embodiment, the fuzzy calculation of the information of the charging vehicles is mainly used for optimally determining schedulable vehicles, so that the schedulable vehicles can be inquired at the vehicle position in a certain area range near the required charging position, specifically, the background server extracts the stored management list of the charging vehicles, obtains the current position information, the vehicle operation state information, the remaining capacity information and the road condition information of each charging vehicle in a first area near the charging position, identifies the optional vehicle according to the vehicle operation state information and the remaining capacity information, that is, the background server firstly screens out the vehicles which are idle at present and to be dispatched according to the vehicle operation state information of the charging vehicles in the first area near the charging position, then further screens the vehicles according to the required capacity and the remaining capacity of the user, and then determines the optional vehicles which can reach the charging position at the charging time according to the current position information and the road condition information of the optional vehicles And (4) vehicles. Of course, if no suitable vehicle is matched within a first area proximate to the charging location, the range of choice for charging vehicles is further expanded, e.g., within 10km of the first area proximate to the charging location and within 20km of the second area proximate to the charging location.
After the primary screening is carried out on the charging vehicles through the steps to obtain the alternative charging vehicles, further, the background server determines the assigned charging vehicles in the alternative charging vehicles according to the required electric quantity so as to ensure that the assigned charging vehicles meet the charging requirements of the vehicles and determine the vehicle IDs of the charging vehicles.
After a vehicle is selected, the background server acquires the information of the current position of the charging vehicle, carries out path planning processing according to the current position and the charging position, preferably selects the optimal driving path and generates a driving planning path, calculates departure time according to the driving planning path and the charging time, and generates charging vehicle scheduling information according to the vehicle ID of the charging vehicle, the charging demand information, the driving planning path and the departure time, so that the charging vehicle is controlled to reach the charging position on time to execute charging service.
It should be noted that when the required electric quantity is specific data, the remaining chargeable quantity is not less than the required electric quantity set by the user when the background server needs to distribute the charging position of the user when the charging vehicle is dispatched; when the required electric quantity is fuzzy data, for example, a user only gives the battery capacity of the vehicle and requires to fully charge the vehicle, but the specific charging capacity of the battery is not set, and the remaining electric quantity of the device to be charged is not given, a charging vehicle with the remaining electric quantity not lower than the battery capacity when the charging vehicle arrives at the charging position is preferred, of course, a charging vehicle with the remaining electric quantity lower than the battery capacity can be assigned, when the current charging vehicle is judged to be incapable of meeting the user requirement during actual charging, on one hand, the charging vehicle is designated to execute charging service, on the other hand, the background server assigns another charging vehicle capable of replenishing the current insufficient electric quantity, and therefore the charging service is completed through cooperation of the two charging vehicles.
And 103, the background server sends the charging demand information, the driving planning path and the departure time information to the assigned charging vehicle according to the vehicle ID.
Specifically, the background server extracts the vehicle ID of the assigned charging vehicle, so as to send the planned driving route and departure time generated in the step 102 to the assigned charging vehicle together with the charging demand information of the user, so as to communicate the assignment task to the charging vehicle.
And step 104, the charging vehicle receives the information of the planned driving path and the departure time, and generates a departure instruction at the departure time, so that the charging vehicle automatically travels to a charging position according to the planned driving path.
Specifically, when a new charging service task is assigned to the charging vehicle, the charging vehicle receives the information of the planned driving path and the departure time sent by the background server, and the charging vehicle updates the navigation data of the driving path according to the information of the planned driving path. Meanwhile, in order to ensure that the background server can better manage the state information of the charging vehicle, the charging vehicle and the background server preferably share the position in real time through 4G/5G. When the departure time is up, the charging vehicle generates a departure instruction, so that the charging vehicle travels to the charging position according to the updated travel path navigation data, and the charging vehicle executes more specific operation.
In order to ensure the charging safety of a user and prevent the electric quantity resource of the charging vehicle from being stolen randomly, the user is required to verify before the charging vehicle arrives at a charging position for charging service, and after the verification is passed, the charging vehicle executes the charging service again.
And 105, generating vehicle arrival information by the charging vehicle, and sending the vehicle arrival information to the user terminal through the background server to prompt the user that the charging vehicle arrives at the charging position and enters a charging preparation stage.
Specifically, when the charging vehicle reaches the charging position, the charging vehicle receives the verification code, matches the received verification code with the authentication code, and provides charging service for the user when the matching is successful.
After the identity authentication of the user is successful, the charging car generates vehicle arrival information and sends the vehicle arrival information to the background server, the background server updates the state information of the charging car according to the vehicle arrival information, and meanwhile, the vehicle arrival information is sent to the user terminal so as to prompt the user that the assigned charging car is in place and is about to enter a charging preparation stage.
The charging vehicle and the equipment to be charged can be charged through wired connection or wireless connection. When the wired connection is adopted for charging, the following two connection modes can be mainly adopted:
firstly, the connection between the charging vehicle and the device to be charged needs the user to participate in the completion, and after the charging vehicle enters the charging preparation stage, the charging vehicle waits for the operation of the user to assist in completing the physical connection between the charging vehicle and the device to be charged.
Secondly, the charging vehicle can automatically and intelligently complete connection with the equipment to be charged, namely, the whole connection process does not need participation of a user, and after the charging vehicle enters a charging preparation stage, the charging vehicle automatically completes physical connection with the equipment to be charged.
And step 106, judging whether the charging vehicle is successfully connected with a charging connector of the equipment to be charged.
Specifically, after the charging vehicle enters the charging preparation stage, the connection state between the charging vehicle and the outside needs to be monitored in real time, when the charging vehicle is connected with the charging connector of the device to be charged, whether the charging vehicle is successfully connected with the charging connector of the device to be charged needs to be detected, after the charging vehicle is successfully connected, the next operation is performed, that is, step 108 is performed, when the connection fails, prompt information needs to be generated to remind a user of the connection failure, the reason of the failure is detected, the connection is performed again, and step 107 is performed. By ensuring the safe connection between the charging device and the charging device, the charging safety is ensured, so that accidents are avoided in the charging process.
When the charging vehicle detects that the charging connector of the charging vehicle and the device to be charged is failed to be connected, the step 106 is proceeded to step 107.
And step 107, when the charging vehicle detects that the charging connector of the charging vehicle and the device to be charged is failed to be connected, generating a connection failure prompt message by the charging vehicle, and sending the connection failure prompt message to the user terminal by the background server.
Specifically, the charging vehicle detects the connection state between the charging connector and the charging connector of the device to be charged, when connection failure is detected, the connection failure reason is further detected, connection failure prompt information is generated according to the detection result and sent to the background server, the background server records the connection failure prompt information and sends the connection failure prompt information to the user terminal, and therefore the user can conveniently know the charging progress in real time and know the reason of the current connection failure.
When the charging vehicle detects that it is successfully connected to the charging connector of the device to be charged, step 108 is entered from step 106.
And 108, when the charging vehicle detects that the charging vehicle is successfully connected with the charging connector of the device to be charged, the charging vehicle generates a charging information extraction instruction, and acquires the information of the residual electric quantity and the actual required electric quantity of the device to be charged according to the charging information extraction instruction.
Specifically, after the physical connection between the charging vehicle and the device to be charged is detected to be successful, the actual residual electric quantity and the required electric quantity of the device to be charged are detected, so that estimation and judgment are carried out according to the actual situation after connection, the estimated and judged result is informed to the user, and therefore the user confirms the charging task according to the self requirement or readjusts the charging task.
And step 109, calculating the estimated charging cost by the charging vehicle according to the preset cost calculation rule according to the planned driving path, the actual power demand and the information of the preselected charging type, and calculating the estimated charging time according to the actual power demand and the information of the preselected charging type and the charging time calculation rule.
Specifically, in order to facilitate the user to know the actual charging cost, the cost calculation is performed according to the actual required electric quantity of the device to be charged after the charging vehicle is physically connected with the device to be charged.
