The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

In the description of the present specification, the terms "comprising," "including," "having," "containing," and the like are used in an open-ended fashion, i.e., to mean including, but not limited to. Reference to the description of the terms "one embodiment," "a particular embodiment," "some embodiments," "for example," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.

Research shows that the electric vehicle charging service network constructed by the current charging operators mainly has the following problems:

1. the centralized control mode of the central platform and the charging piles requires that the central platform and the network of the charging piles must be smooth, so that the requirements of the construction environment of the charging piles are improved to a certain extent, and the construction cost is increased.

2. Under the offline scene, because the credibility between the client and the charging pile can not be established through the authentication of the central platform, the charging pile can not charge the electric automobile.

3. Under the condition that the network is unstable, after charging is completed, charging and payment efficiency is low, and user experience is poor.

In view of the above problems, research and development personnel need to find a method for establishing authentication and billing locally through point-to-point communication. Therefore, the embodiment of the invention provides a charging payment method and device for an electric vehicle, wherein a charging pile and a client can establish local connection through near field communication so as to realize point-to-point identity authentication between the charging pile and the client in an offline scene; and after charging, charging pile and client end can utilize user's electronic purse to make local point-to-point payment and settlement. Under the condition that the charging pile and the client can establish network connection with a charging management platform (namely a central platform), the charging bill is sent to the charging management platform, and the balance of the electronic wallet of the user is modified by the charging management platform, so that the account information synchronization of the local account and the charging management platform can be realized.

As shown in fig. 1, a flowchart of an electric vehicle charging payment method provided in an embodiment of the present invention is applied to a charging pile, and the method may include the following steps:

step 101, receiving an electric vehicle charging request initiated by a client through near field communication;

step 102, sending a request for acquiring user authentication information to a client according to the electric vehicle charging request;

103, receiving user authentication information fed back by the client according to the request for obtaining the user authentication information;

step 104, checking the user authentication information;

105, generating charging information after the verification is passed, wherein the charging information comprises charging pile information and a charging key;

step 106, sending the charging information to the client so that the client generates a charging order according to the charging information;

step 107, receiving a charging order sent by a client, wherein the charging order comprises charging pile information, client information, a preset charging amount, a preset charging time and a preset charging amount;

step 108, confirming the charging order, and starting a charging mode to charge the electric automobile after confirming that the data in the charging order is correct;

step 109, after the charging is finished, generating a charging bill, wherein the charging bill comprises charging pile information, client information, a charging amount, a charging time period, a charging duration and a charging amount;

step 110, sending the charging bill to the client so that the client confirms the charging bill;

step 111, after receiving the bill confirmation information sent by the client, generating charge settlement information corresponding to the charging bill according to the charging rule;

step 112, sending the charge settlement information corresponding to the charging bill to the client, so that the client stores the charge settlement information corresponding to the charging bill;

and 113, under the condition that the charging pile is connected with the charging management platform through a network, sending the charging bill and the charge settlement information corresponding to the charging bill to the charging management platform, so that the charging management platform modifies account information corresponding to the client after verifying the charging bill and the charge settlement information corresponding to the charging bill, and completes charging payment.

Compared with the technical scheme that charging is carried out in a centralized control mode of 'a central platform + a charging pile' in the prior art, the embodiment of the invention can realize point-to-point local connection between the charging pile and the client side in an offline scene through near field communication, further complete user authentication and charging processes, and meanwhile, after charging is completed, local related transaction records can be synchronized to the charging management platform in an online scene, so that clearing settlement is realized, charging and payment efficiency of users can be improved, and further user experience is improved.

In the step 101, the client initiates an electric vehicle charging request to the charging pile through Near Field Communication (NFC), and the charging pile receives the electric vehicle charging request.

The electric vehicle charging request may be a request for instructing a client to request the near field communication connection with the charging pile to charge the electric vehicle.

In the embodiment of the invention, under the scene that any one of the client and the charging pile is offline or both the client and the charging pile are offline at the same time, local connection can be established through near field communication; or, in a scene that the network environment of any one of the client and the charging pile is poor, the local connection can be established through near field communication.

Therefore, the embodiment of the invention can establish the point-to-point credible authentication of the charging pile and the client through the near field communication technology, and realize the distributed control of the charging process. And the near field communication technology has no requirement on the charging management platform and the charging pile network, so that the coupling of the charging management platform and the charging pile and the complexity of the charging control service logic are reduced to a certain extent, the network construction cost is reduced, and the operation benefit is improved.

In addition, since the charging transaction is in an offline scenario, the charging business process is vulnerable to various types of security attacks, such as agent attack, which causes losses to users and operators, and therefore, various security risks in the offline scenario must be fully considered. Therefore, in the embodiment of the present invention, a Public Key Infrastructure (PKI) is further adopted to establish a unified trusted domain of the client and the charging pile, so as to reduce various security risks of the charging service flow in an offline environment.

In the step 102, the charging pile establishes a local connection with the client according to the electric vehicle charging request initiated by the client. And sends a request for obtaining user authentication information to the client.

The request for obtaining the user authentication information may include a charging pile public key.

Specifically, the client receives the request for obtaining the user authentication information, and obtains the user authentication information from the security module SE, where the user authentication information may include a client public key, a user electronic wallet record, user identity information, charging vehicle information, and the like.

The user electronic wallet record may be a historical charging transaction record of a user corresponding to the client, or another historical transaction record performed by the user using the electronic wallet.

It should be noted that the security module SE of the client may be used to implement functions such as secure storage of data, encryption and decryption operations, and improve security of data storage and data transmission.

In the embodiment of the invention, in order to ensure the security of user data transmission, a client needs to encrypt and sign user authentication information, and specifically, the client encrypts a user electronic wallet record by using a charging pile public key; and signing the encrypted user electronic wallet record by using the client private key, and sending the client public key and the signed encrypted user electronic wallet record to the charging pile.

In step 103, the charging pile receives the user authentication information fed back by the client. The user authentication information comprises a client public key and a user electronic wallet record which is signed by the client private key and encrypted by the charging pile public key.

In step 104, the charging pile verifies the user authentication information.

Specifically, the step 104 may include:

carrying out signature verification on the user electronic wallet record by using a client public key;

after the signature verification is passed, decrypting the user electronic wallet record by using a charging pile private key;

and performing compliance verification on the decrypted user electronic wallet record, wherein the compliance verification comprises whether the user electronic wallet record is blacklisted and/or whether an unpaid charging record exists.

Therefore, in the embodiment of the invention, the compliance verification is carried out on the records of the electronic wallet of the user, so that the charging of the user which does not conform to the regulations can be avoided, and the loss brought to a charging operator is avoided.

In step 105, after the user authentication information is verified, the charging pile may generate charging information for the current charging according to the user authentication information. The charging information may include charging pile information and a charging key.

Wherein, the charging pile information can comprise a charging pile number, charging operator information to which the charging pile belongs, charging billing information and the like. The charging key is a key for encrypting data of the current charging.

In step 106, the charging pile sends the charging information to the client.

Specifically, in order to ensure the security of the data transmission process, before the step 106, the method further includes:

generating a charging key, and encrypting charging pile information by using the charging key;

encrypting the charging key by using a client public key carried by the user authentication information;

signing the encrypted charging pile information and the encrypted charging key by using a charging pile private key;

the step 106 may specifically include:

and sending the signed encrypted charging pile information and the encrypted charging key to the client.

The client receives the signature sent by the charging pile by using the private key of the charging pile: after the charging pile information encrypted by the charging key and the charging key encrypted by the client public key, the charging information needs to be decrypted and signed.

Specifically, the client side utilizes the charging pile public key to perform signature verification on the charging pile information and the charging key; after the signature verification is passed, the client decrypts the charging key by using a client private key; and the client decrypts the encrypted charging pile information by using the decrypted charging key to obtain the decrypted charging pile information.

And the client generates a charging order according to the decrypted charging pile information. The charge order may include: charging pile information, client information, charging amount, charging time period, charging duration and charging amount.

In order to ensure data security, the client may encrypt and sign the charging order and then send the charging order to the charging pile. Specifically, the client encrypts the charging order by using the charging key; the client signs the encrypted charging order by using a client private key; and the client sends the signed encrypted charging order to the charging pile.

In the embodiment of the invention, after the client generates the charging order, the preset bill amount can be frozen in the user electronic wallet.

Therefore, the payment can be ensured to be smoothly finished after the current charging by freezing the preset bill amount, and the charging failure caused by the fact that the balance in the electronic wallet is not enough to pay the current charging amount is avoided.

In step 107, the charging pile receives the charging order sent by the client.

In step 108, the charging pile confirms the charging order, and after confirming that the data in the charging order is correct, the charging mode is started to charge the electric vehicle.

Specifically, since the charge order sent by the client is a charge order signed by the client private key and encrypted by the charge key, the step 108 of confirming the charge order may include:

utilizing a client public key to carry out signature verification on the charging order;

after the signature verification is passed, decrypting the charging order by using the charging key;

and confirming whether the data in the decrypted charging order is correct or not.

After the charging pile determines that the data in the decrypted charging order are correct, the charging mode can be started to charge the electric automobile.

In step 109, after the charging is finished, the charging pile generates a charging bill, which may include a transaction serial number, charging pile information, client information, a charging amount, a charging time period, a charging amount, and the like.

In the step 110, the charging pile sends the charging bill to the client.

In order to ensure the security of data transmission, before step 110, the method may further include:

encrypting the charging bill by using the charging key;

signing the encrypted charging bill by using a private key of the charging pile;

step 110 may specifically include:

and sending the encrypted charging bill after signature to the client.

After receiving a charging bill which is sent by a charging pile and is signed by a private key of the charging pile and encrypted by a charging key, the client side utilizes a public key of the charging pile to carry out signature verification on the charging bill; after the signature verification is passed, the client decrypts the charging bill by using the charging key; and the client side confirms whether the data in the decrypted charging bill is correct or not.

And the client encrypts the bill confirmation information by using the charging key under the condition of confirming that the data in the decrypted charging bill is correct, signs the encrypted bill confirmation information by using a client private key, and sends the signed encrypted bill confirmation information to the charging pile.

In step 111, after receiving the signed encrypted bill validation information sent by the client, the charging pile performs signature verification on the bill validation information by using the client public key, decrypts the bill validation information by using the charging key after the signature verification is passed, and generates charge settlement information corresponding to the charging bill according to the charging rule under the condition that the bill validation information is correct.

The charging rules can be charging rules preset by the charging pile, and can be calculated according to charging unit price, duration, charging amount and the like.

In addition, in the embodiment of the invention, after the charging pile generates the charge settlement information corresponding to the charging bill, the charging pile can also store the charging bill and the corresponding charge settlement information which are charged at this time into the safety module SE of the charging pile so as to ensure that the data cannot be stolen or lost.

In step 112, the charging pile encrypts the charge settlement information corresponding to the charging bill by using the charging key, signs by using the private key of the charging pile, and sends the information to the client.

The client receives charge settlement information which is sent by the charging pile and is signed by the charging pile private key and encrypted by the charging key, signature verification is carried out on the charge settlement information by using the charging pile public key, after the signature verification is passed, the charge settlement information is decrypted by using the charging key, the decrypted charge settlement information is confirmed to be correct, and a charging bill and the corresponding charge settlement information are stored in a security module SE of the client, so that data cannot be stolen or lost.

Therefore, the embodiment of the invention can realize local point-to-point charging transaction settlement without the charging management platform under the condition that the charging pile and the client cannot be connected with the charging management platform through the near field communication technology.

In addition, in embodiments of the present invention, it is also contemplated to synchronize local related transaction records to the central platform in an appropriate manner.

In the step 113, in the case that the charging pile is online, the charging bill and the charge settlement information corresponding to the charging bill can be sent to the charging management platform, the charging management platform can verify the charging bill and the charge settlement information corresponding to the charging bill, which are sent by the charging pile and the client respectively, and after the verification is passed, the account information corresponding to the client is modified, and the charging payment is completed.

Specifically, the charging management platform verifies the charging bill and the charge settlement information corresponding to the charging bill, and may confirm that the charging bill and the charge settlement information corresponding to the charging bill sent by the charging pile and the client are consistent.

Therefore, the synchronization of the local account information and the account information of the charging management platform can be ensured, and the clearing settlement is realized.

Based on the above description, an embodiment of the present invention provides another electric vehicle charging payment method, which is applied to a client of the electric vehicle charging payment system. The implementation of the method can refer to the implementation of the electric vehicle charging payment method taking the charging pile as the execution main body, and repeated parts are not repeated.
