Charging method, device and storage medium

Technical Field

The present application relates to the field of automobile charging technologies, and in particular, to a charging method, a device and a storage medium.

Background

The mode of the two-dimensional code scanning identification of the charging of the new energy automobile is gradually replaced by the plug-and-play technology. The plug-and-play technology greatly improves the user experience and is a development trend of intelligent charging in the future. The plug-and-play function enables vehicles, piles, vehicle clouds and pile clouds to be communicated through the vehicle networking platform, and plug-and-play charging of the plug gun is achieved. After the plug-and-play function is started, the automobile charging only needs two steps: the charging gun is inserted, the 'plug and play' button on the charging pile is clicked, other operations are not needed, and the system is automatically authenticated and charged through starting.

At present, plug-and-play has two defects: on the one hand, when the plug-and-play function is firstly opened, a 4G/5G network is needed, and a cloud platform without the 4G/5G network cannot communicate with an APP or a charging pile, so that the plug-and-play function cannot be realized; on the other hand, after the plug-and-play function is started, the mobile phone needs to be carried close to the charging pile during each charging, bluetooth needs to be started on the mobile phone, and the mobile phone is successfully connected with the charging pile manually or automatically, so that the plug-and-play function can be realized.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application.

Before describing the embodiments of the present application, a brief description will be first made of the technical concept of the present application.

CAN communication: the CAN bus communication system is one of serial communication and is superior to an RS485 bus. Unlike I2C, SPI, which is synchronous with a clock signal, CAN communication is not synchronous with a clock signal, which is an asynchronous half duplex communication. The synchronous data communication is driven by the same clock, and the half duplex receiving and transmitting cannot be performed simultaneously.

The present inventors have noted that there are two prior art approaches to the plug-and-play technique, prior art 1: based on the cellular mobile data communication network such as 4G and the like, the cloud platform is used as an overall information dispatcher to realize the plug-and-play function. Specifically: the user starts the plug and play authorization process through the APP, the APP sends an authorization instruction to the cloud platform, the cloud platform sends the authorization instruction to the charging pile, the charging pile stores the vehicle identification code uploaded by the BMS through CAN communication into a plug and play function authorization list, and the vehicle identification code CAN be regarded as being opened by the plug and play function (the vehicle identification code CAN be uploaded to the cloud platform by the charging pile firstly and stored into the authorization list by the cloud platform). After the subsequent charging only needs to be carried out by inserting a gun, the charging pile or the cloud platform automatically identifies whether the vehicle identification code uploaded by the BMS is matched with the identification code in the authorized list, and if so, the charging is directly started. Prior art 2: based on Bluetooth communication, after Bluetooth of a mobile phone is connected with Bluetooth of a charging pile, a user starts a plug-and-play authorization process through an APP, and after Bluetooth keys are matched, the charging pile adds a mobile phone Bluetooth MAC address into a plug-and-play authorization list; after the subsequent charging gun insertion, the mobile phone is close to the charging pile, the mobile phone Bluetooth is opened, and the charging pile Bluetooth identifies that the mobile phone MAC Bluetooth address is the Bluetooth MAC address in the authorized list, and then charging is started.

However, prior art 1 has the following drawbacks: when the plug-and-play function is first opened, a 4G network is needed, and a cloud platform without the 4G network cannot communicate with the APP or the charging pile, so that the plug-and-play function cannot be realized. Likewise, prior art 2 suffers from the following drawbacks: after the plug-and-play function is started, the mobile phone needs to be carried close to the charging pile after each charging, and the mobile phone needs to be started with Bluetooth and is successfully or automatically connected with the charging pile (the automatic connection needs to be carried out by the charging pile Bluetooth to support noninductive authentication, and the cost is increased), so that the plug-and-play function can be realized. That is, the plug-and-play function does not truly implement plug-and-play, with the additional condition that the user needs to complete bluetooth connection between the mobile phone and the charging post each time the user charges. In view of this, the embodiment of the present application provides a charging method as described below:

referring to fig. 1, fig. 1 is a schematic flow chart of a charging method according to an embodiment of the present application, where the charging method is applied to a system including a charging pile end and a user terminal, and the charging pile end is connected with the user terminal in a communication manner; the method may include: step 100, step 110, step 120, step 130, step 140 and step 150.

Step 100: under the condition that near field communication connection is established between the user terminal and the charging pile, receiving a request of the user for authorizing the charging vehicle to open the plug-and-play function, and sending a plug-and-play binding instruction to the charging pile based on the request; the method comprises the steps of requesting to carry identity information of a charging vehicle input by a user;

step 110: receiving a plug-and-play binding instruction sent by a user terminal by a charging pile terminal under the condition of establishing near field communication connection with the user terminal; the plug-and-play binding instruction is generated by triggering after the user terminal agrees to authorize the binding of the identity information of the charging vehicle;

step 120: judging whether to write the identity information of the charging vehicle into a plug-and-play authorization list based on a plug-and-play binding instruction by the charging pile terminal, and correspondingly sending a binding result of whether the charging vehicle is successfully bound to the user terminal;

step 130: the user terminal receives a binding result of whether the charging vehicle is successfully bound or not, wherein the binding result is sent by the charging pile;

step 140: if the identity information of the charging vehicle is written into the plug-and-play authorization list, the charging pile terminal authorizes the charging of the charging vehicle;

step 150: and prompting the user whether the charging vehicle successfully opens the plug-and-play function at the user terminal by the user terminal according to the binding result.

The charging pile end can be a charging pile distributed on a vehicle, can charge various types of electric automobiles according to different voltage levels, and can be a direct current private pile. The user terminal can be a mobile terminal or an application program APP on a computer terminal which can control the charging pile terminal to start charging after registering and logging in an account. The user terminal and the charging pile terminal may establish a communication connection through near field communication, for example: the communication between the charging pile and the mobile phone APP is realized through Bluetooth.

Wherein, the near field communication connection may be: communication connection established based on a near-distance wireless communication technology can also comprise Radio Frequency Identification (RFID), NFC, zigBee, infrared, wi-Fi and other technologies besides Bluetooth (Bluetooth). The authorization list may be: the concept of the authorized list corresponds to an "unauthorized list", for example, in a computer system, a user (or an IP address, an IP packet, mail, virus, etc.) listed in the unauthorized list cannot pass through; if the authorization list is established, users (or IP addresses, IP packets, mails and the like) in the authorization list can pass preferentially and cannot be rejected as junk mails, and the same charging field is like that of the charging pile system, so that the binding vehicles in the authorization list can have the authority of plug and play, and plug and play charging is realized. The identity information may be: the vehicle identification number VIN representing the unique identification of the charged vehicle or the simple identification number of the vehicle identification number VIN, the engine number, the vehicle license information, the purchase invoice information, the license plate number, the vehicle brand type, and the like.

The plug-and-play function may be: when the electric automobile or the plug-in hybrid electric automobile is plugged in the charging gun, the battery can be started to be charged, a series of operations such as authentication and charging are automatically realized on the automobile, and the card swiping/code scanning is omitted, so that the user can charge the battery as conveniently as oiling. At present, the charging equipment newly developed by each vehicle type is respectively provided with a plug-and-play function, a user can bind the vehicle identity information of a target vehicle through a mobile phone APP, and the APP can be the mobile phone APP which is self-developed by a host factory of a manufacturer.

As shown in fig. 2, the following embodiment uses a mobile phone APP as a user terminal, and the near field communication is illustrated by taking bluetooth communication to establish a connection as an example.

The process of establishing near field communication connection between the user terminal and the charging pile can be as follows: the mobile phone APP end completes user registration and login, and binds an APP account with the charging pile end by means of scanning or manually inputting charging pile codes and the like; the charging pile end is electrified (Bluetooth broadcasting is automatically started), and the mobile phone opens Bluetooth and completes connection with the charging pile Bluetooth; after a user clicks 'plug and play' in a mobile phone APP terminal, the APP can send a Bluetooth key to a charging pile terminal, and the charging pile terminal checks whether the Bluetooth key is consistent with a locally generated Bluetooth key after receiving the Bluetooth key of the APP, and returns an APP key checking result; the mobile phone APP end receives the key verification success, and the popup frame prompts the user to complete connection of the charging pile and the vehicle; re-sending the Bluetooth key if the verification fails, and exiting the plug-and-play binding process (a is a calibration value) if the verification exceeds a times; after detecting the connection of the charging gun, the charging pile end sends the connection state to the mobile phone APP end, and after receiving the connection OK of the charging gun, the APP prompts a user whether to agree to authorize the current connected vehicle to open the plug-and-play function; when the charging gun is not connected with OK, the user is prompted to connect the charging pile with the vehicle, and when the charging gun is not connected for more than b minutes, the plug-and-play charging binding process can be exited (b is a calibration value).

The Bluetooth key can be automatically generated by the APP after the charging pile codes are input according to a given algorithm, and the charging pile generates the Bluetooth key when the number is input from a factory; one charging pile code can only generate a unique Bluetooth key, and the charging pile and the APP are unified in algorithm, namely, the Bluetooth keys generated by the charging pile code are consistent.

For step 100: after the Bluetooth connection is established between the user terminal and the charging pile terminal, namely after a user clicks a charging interface related to the mobile phone APP terminal to agree with authorizing to open the plug-and-play function, an instruction for requesting authorization is initiated to the system, and a popup frame prompts the user to input a simple identification code (identity information) of the vehicle; if the user does not click on the approval authority for more than c minutes, the plug-and-play process can be exited (c is a calibration value); after the user clicks the grant and inputs the simple identification code, the mobile phone APP end sends a plug-and-play binding instruction to the charging pile end, and the instruction information synchronously transmits the simple identification code. Wherein: the simple identification code is used for distinguishing and binding the identity of the vehicle for the user, and the simple identification code and the vehicle identification code VIN belong to a one-to-one correspondence.

For steps 110 and 120: after Bluetooth connection is established between the charging pile end and the user terminal, namely after the charging pile receives a plug-and-play charging binding instruction sent by the mobile phone APP end, whether identity information of the charging vehicle is written into a plug-and-play charging authorization list or not is judged according to the current states of the vehicle and the charging pile, and a binding result of whether the charging vehicle is successfully bound or not is correspondingly sent to the mobile phone APP.

For step 130: and the mobile phone APP receives a binding result of whether the charging vehicle sent back by the charging pile end is successfully bound or not, and carries out related popup prompt on the user according to the binding result.

For step 140: if the charging pile end and the vehicle are successfully bound, namely the identity information of the charging vehicle is written into the plug-and-play charging authorization list, the charging can be directly started, and the charging pile directly and locally authorizes to start charging. Meanwhile, a mobile phone APP end plug-and-play binding result is returned, and a binding flow is completed. If the APP binding instruction or BMS effective vehicle identification code is not received in the overtime, the gun inserting charging process is ended according to the GB/T27930 (communication protocol between the national standard electric vehicle non-vehicle-mounted conductive charger and the battery management system) communication overtime specification. Through the means of bluetooth communication, the vehicle identity information is directly written into the local plug-and-play function authorization list of the charging pile, the identity of the mobile phone is identified in a bluetooth communication mode, and the authorization instruction is not dispatched through the cloud platform in a 4G communication mode.

Optionally, the application can also be applied to the field of alternating-current charging, and the core idea is that the charging pile records the vehicle identity information to the plug-and-play function authorization list through a Bluetooth communication means. Because the communication between the alternating-current charging pile and the vehicle is hard-wire communication, the vehicle identity information is not easy to record, but the vehicle identity information can be transmitted by defining a combined edge signal of a CP signal (control guide signal), and meanwhile, a specific communication protocol between the charging equipment and the vehicle is established.

For step 150: the mobile phone APP end successfully binds according to the binding result returned by the charging pile end, namely, the identity information of the charging vehicle is written into a plug-and-play authorization list, and the user is prompted that the current connecting vehicle has an opening plug-and-play function; otherwise, prompting the binding failure and displaying the reason, and ending the binding flow. In particular, one charging stake can bind a plurality of vehicle identification codes, open plug and play function for a plurality of vehicles. And as long as unbinding is not carried out after binding, when the charging vehicle charges for the second time or for a plurality of times later, bluetooth connection is not required to be re-established again for binding again, namely, application and vehicle binding operation are only required to be carried out once on a mobile phone APP, the effect of permanent authorization of once binding is realized, convenience and quickness are realized, and the use experience of a user is improved.

Referring to fig. 3, fig. 3 is a flowchart of a charging method applied to a charging pile end according to an embodiment of the present application, and a specific flow of the embodiment is explained in detail below. The method may include: step 111, step 112 and step 113.

Step 111: under the condition of establishing near field communication connection with a user terminal, receiving a plug-and-play binding instruction sent by the user terminal; the plug-and-play binding instruction is generated by triggering after the user terminal agrees to authorize the binding of the identity information of the charging vehicle;

Step 112: based on the plug-and-play binding instruction, judging whether to write the identity information of the charging vehicle into a plug-and-play authorization list, and correspondingly sending a binding result of whether the charging vehicle is successfully bound to the user terminal;

step 113: and if the identity information of the charging vehicle is written into the plug-and-play authorization list, authorizing the charging vehicle to charge.

The charging pile end is connected with the mobile phone APP end in a Bluetooth mode, and after the charging pile receives a plug-and-play charging binding instruction sent by the mobile phone APP end, whether identity information of the charging vehicle is written into a plug-and-play charging authorization list or not is judged according to the current states of the vehicle and the charging pile, and a plug-and-play charging binding result of the mobile phone APP end is returned to complete a binding flow. If the charging pile end and the vehicle are successfully bound, namely the identity information of the charging vehicle is written into the plug-and-play charging authorization list, the charging can be directly started, and the charging pile directly and locally authorizes to start charging.

When a user uses the plug-and-play function, the user only needs to insert the charging gun into a charging port of a target charging vehicle, the vehicle can automatically upload vehicle identity information and charging pile information to a cloud (for example, a charging service platform), and the cloud verifies whether the vehicle enables the plug-and-play function. After the user completes the connection between the vehicle and the charging pile, the charging pile outputs an auxiliary power supply to wake up the vehicle, the vehicle BMS sends a vehicle identification code to the charging pile, the charging pile judges whether the vehicle identification code is an identification code in a local plug-and-play function authorization list, and if so, the charging pile directly authorizes to start charging; if not, other instructions are waited to be executed or the GB/T27930 communication is overtime to exit the charging process.

The vehicle and the charging pile are communicated through CAN communication, and the communication protocol of national standard GB/T27930 is met. Particularly, according to the charging flow after the plug-and-play function is started, the plug-and-play function can be started only after a user plugs a gun in each charging, so that the plug-and-play function is truly plug-and-play. In the prior art 2, after the plug-and-play function is opened, connection of the mobile phone bluetooth and the charging pile bluetooth needs to be completed every time of charging, otherwise, plug-and-play cannot be realized. Firstly, the Bluetooth of the mobile phone is always open and is not the use habit of all users, and the always open Bluetooth of the mobile phone also has the risks of high power consumption of the mobile phone, unsafe information of the mobile phone and the like; secondly, the connection reliability of the Bluetooth network is also a problem; meanwhile, to realize the automatic connection of the Bluetooth after binding, the charging pile Bluetooth also needs to support noninductive authentication to realize the automatic connection with the mobile phone Bluetooth, and the cost is increased due to the selection of a Bluetooth chip; finally, the mobile phone cannot be charged by plug-and-play without being at hand, and the charging pile without the card reader cannot be charged even. The present invention avoids the above problems.

After the flow shows that the plug-and-play function is started, the user only needs to plug a gun, other additional complicated operations are not needed, the complexity of the charging authentication process is reduced, and likewise, only one-time starting application and vehicle binding operation are needed at the APP end of the mobile phone, so that one-time binding permanent authorization can be realized, and the user experience is improved. Meanwhile, near field communication in the application includes near field communication modes such as bluetooth communication and NFC communication which are common in the art, and in the process of configuring related execution algorithms, an execution chip (e.g. bluetooth chip) of the near field communication is not required to support non-inductive authentication, so that authentication and communication by using the near field communication have the advantage of low cost.

In one embodiment, step 112 may specifically include: step 112a and step 112b.

Step 112a: if a plug-and-play binding instruction and a vehicle identification code are received, writing the identity information into a plug-and-play authorization list, and correspondingly sending a binding result of successful binding of the charging vehicle to the user terminal; the vehicle identification code is obtained from a charging vehicle which is awakened based on the plug-and-play charging binding instruction through the charging pile;

step 112b: and if the plug-and-play binding instruction or the vehicle identification code is not received, correspondingly sending a binding result that the charging vehicle is not successfully bound to the user terminal.

For example, after receiving a plug-and-play binding instruction sent by a mobile phone APP end, the charging pile outputs an auxiliary power supply to wake up a vehicle, and a vehicle BMS (Battery Management System ) sends vehicle identification code information to the charging pile end through a handshake link between the vehicle and the pile; the charging pile terminal judges whether a plug-and-play binding instruction sent by the mobile phone APP terminal is received or not, receives an effective vehicle identification code sent by the BMS, writes the vehicle identification code and simple identification code information into a plug-and-play authorization list if the vehicle identification code and the simple identification code information are received, returns a plug-and-play binding result of the mobile phone APP terminal, and completes a binding process. After the plug-and-play binding instruction is determined to be received, the auxiliary power supply is output to wake the vehicle to acquire the vehicle identification code sent by the vehicle BMS, so that the problem of communication overtime of the charging process caused by untimely authorization of the gun insertion can be avoided, and the binding success rate is improved.

In one embodiment, step 113 may further specifically include: step 114 and step 115.

Step 114: under the condition of establishing near field communication connection with a user terminal, receiving a plug-and-play binding instruction sent by the user terminal; the plug-and-play unbinding instruction is generated by triggering after the user terminal agrees to authorize unbinding the identity information of the charging vehicle;

step 115: based on the plug-and-play unbinding instruction, the identity information is removed from the plug-and-play authorization list, and an unbinding result of whether unbinding of the charging vehicle is successful or not is sent to the user terminal.

Illustratively, as shown in fig. 4, a plug-and-play charging and unbinding flow is shown, after the charging pile is powered on (bluetooth broadcast is automatically turned on), the mobile phone turns on bluetooth and completes connection with the charging pile bluetooth; after receiving the plug-and-play charging and unbinding instruction of the mobile phone APP end, the charging stake removes the serial number corresponding to the simple identification code, the vehicle identification code and the simple identification code information from the charging stake local plug-and-play charging authorization list, and returns a unbinding result to the mobile phone APP end.

According to the plug-and-play binding or unbinding flow at the charging pile end, the realization of the binding and unbinding does not need the on-line or WIFI network of 4G, 5G and other cellular networks, namely the network can finish the opening or closing of the plug-and-play function, the situation that the plug-and-play function is required to be used under the condition that a plurality of charging pile installation sites have no network or network is bad can be solved, the user experience is greatly improved, and the opening of the plug-and-play function can not be finished in the 4G communication without the prior art 1.

In one embodiment, the charging method further comprises: if the user terminal inquires the plug-and-play binding list after successful binding or unbinding, the plug-and-play binding list is correspondingly updated according to the plug-and-play authorization list stored by the charging pile.

After the binding procedure is finished, a user can inquire a plug-and-play binding list after the binding is successful through the mobile phone APP end, the list is based on the charging pile local, and the mobile phone APP end synchronously updates the charging pile local plug-and-play list in the inquiring process; after the unbinding flow is finished, the user can inquire the plug-and-play binding list after unbinding success through the mobile phone APP terminal, the list is based on the charging pile local, and the mobile phone APP terminal synchronously updates the charging pile local plug-and-play list in the inquiring process. By inquiring the plug-and-play binding list after successful binding or unbinding, whether the charging vehicle is successful in binding or unbinding can be determined more intuitively, and the list can be updated in real time, so that a maintenance effect is achieved.

step 122: receiving a binding result of whether the charging vehicle is successfully bound or not, which is sent by the charging pile;

step 123: and prompting the user whether the charging vehicle successfully opens the plug-and-play function at the user terminal according to the binding result.

After the bluetooth connection is established between the user terminal and the charging pile terminal, namely after the user clicks a charging interface related to the mobile phone APP terminal to agree with authorizing to open the plug-and-play function, an instruction for requesting authorization is initiated to the system, and a popup frame prompts the user to input a simple identification code (identity information) of the vehicle; after a user clicks and agrees with authorization and inputs a simple identification code, the mobile phone APP end sends a plug-and-play binding instruction to the charging pile end, and instruction information synchronously transmits the simple identification code; the mobile phone APP receives a binding result of whether the charging vehicle sent back by the charging pile end is successfully bound or not, and carries out related popup prompt on a user according to the binding result; the mobile phone APP end prompts the user that the vehicle is connected currently and the plug-and-play function is opened according to the binding result returned by the charging pile end after the binding is successful; otherwise, prompting the binding failure and displaying the reason, and ending the binding flow.

As long as unbinding is not carried out after binding, when the charging vehicle charges for the second time or for a plurality of times later, bluetooth connection is not required to be re-established for binding again, namely, application and vehicle binding operation are only required to be carried out once at the mobile phone APP, the effect of permanent authorization of once binding is achieved, convenience and quickness are realized, and the user experience is improved.

In one embodiment, after step 123, the method further comprises: step 124, step 125 and step 126.

Step 124: under the condition of establishing Bluetooth connection with a charging pile, receiving a request of a user agreeing to authorize a charging vehicle to close a plug-and-play function, and sending a plug-and-play unbinding instruction to the charging pile based on the request; the method comprises the steps of requesting to carry identity information of a charging vehicle input by a user;

step 125: receiving a unbinding result of whether unbinding of the charging vehicle is successful or not, which is sent by the charging pile;

step 126: and prompting the user whether the charging vehicle successfully closes the plug-and-play function at the user terminal according to the binding-releasing result.

After the user clicks the plug-and-play inlet, selecting a simple identification code corresponding to the vehicle to be unbinding, and sending an unbinding plug-and-play instruction (synchronous transmission simple identification code) to the charging pile after the user authorization confirmation is obtained; and the mobile phone APP end prompts the user according to the unbinding result, if unbinding is successful, prompts the user that the vehicle has closed the plug-and-play function, otherwise prompts unbinding failure and reasons, and the unbinding flow is ended.

According to the plug-and-play binding or unbinding flow of the user terminal, the implementation of the binding and unbinding does not need 4G network on-line, namely the network can be opened or closed by completing the plug-and-play function on-line or off-line, the situation that the plug-and-play function is required to be used under the condition that a plurality of charging piles are installed on a site without the network or the network is bad can be solved, the user experience is greatly improved, and the opening of the plug-and-play function can not be completed in the case that the 4G communication is not available in the prior art 1.
