The research shows that the electric automobile charging service network built by the charging operators at present mainly has the following problems:

1. the centralized control mode of the central platform and the charging pile requires that the network of the central platform and the charging pile is unobstructed, which improves the requirements of the construction environment of the charging pile to a certain extent and increases the construction cost.

2. Under the off-line scene, because the credibility between the client and the charging pile cannot be established through the authentication of the center platform, the charging pile cannot charge the electric automobile.

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

In view of the above, there is a need for developers to find a way to establish authentication and billing locally through point-to-point communication. Therefore, the embodiment of the invention provides a charging payment method and a charging payment device for an electric automobile, 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 the charging is completed, the charging pile and the client can utilize the electronic wallet of the user to carry out local point-to-point payment settlement. Under the condition that the charging pile and the client can establish network connection with a charging management platform (namely a center platform), a charging bill is sent to the charging management platform, and the charging management platform carries out balance modification of the user electronic wallet, so that account information synchronization of a 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 by 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, according to the electric automobile charging request, a request for acquiring user authentication information is sent to a client;

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

104, checking the user authentication information;

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

step 106, the charging information is sent 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 duration 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 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, the charging bill is sent to the client so that the client confirms the charging bill;

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

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

and 113, under the condition that the charging pile and the charging management platform are connected in 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 the account information corresponding to the client after verifying the charging bill and the charge settlement information corresponding to the charging bill, and charging payment is completed.

In the embodiment of the invention, compared with the technical scheme of charging in a centralized control mode of a central platform and a charging pile in the prior art, the embodiment of the invention can realize the point-to-point local connection of the charging pile and a client under an offline scene through near field communication so as to finish user authentication and charging flow, and simultaneously, after charging is finished, local related transaction records can be synchronized to a charging management platform under an online scene so as to realize clear settlement, thereby improving the charging and payment efficiency of users and further improving user experience.

In 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 indicating that the client requests to establish near field communication connection with the charging pile so as to charge the electric vehicle.

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

In this way, the embodiment of the invention can establish the point-to-point trusted 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 network of the charging management platform and the charging pile, so that the coupling property of the charging management platform and the charging pile and the complexity of charging control business 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 easily subjected to various security attacks, such as agent attacks, which cause losses to users and operators, and therefore, various security risks in the offline scenario must be fully considered. Therefore, in the embodiment of the invention, a public key infrastructure (Public Key Infrastructure, PKI) is also adopted to establish a unified trusted domain of the client and the charging pile, so that various security risks of the charging business process in an offline environment are reduced.

In 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 acquiring 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 secure 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 so on.

The electronic wallet record of the user can be a historical charging transaction record of the user corresponding to the client, or other historical transaction records of the user using the electronic wallet.

The secure module SE of the client may be used to implement functions such as secure storage of data, encryption and decryption operations, and the like, so as to improve security of data storage and data transmission.

In the embodiment of the invention, in order to ensure the safety of user data transmission, a client needs to encrypt and sign user authentication information, and specifically, the client encrypts a user electronic purse 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 includes a client public key and a user electronic wallet record signed with a client private key and encrypted with a charging stub public key.

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

Specifically, the step 104 may include:

In this way, in the embodiment of the invention, through compliance verification on the electronic wallet records of the user, the charging of the user which does not meet the regulations can be avoided, and the loss to the charging operator is avoided.

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

The charging pile information may include 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 charging information to the client.

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

generating a charging key, and encrypting the 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 a signature sent by the charging pile and signed by the charging pile private key: after the charging pile information is encrypted with the charging key and the charging key is encrypted with the client public key, the charging information needs to be decrypted and signed.

Specifically, the client performs signature verification on charging pile information and a charging key by using a charging pile public key; after the signature verification is passed, the client decrypts the charging key by using the client private key; and the client decrypts the encrypted charging pile information by using the decrypted charging key to obtain 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, a charging amount, a charging period, a charging duration, and a charging amount.

To ensure data security, the client may encrypt and sign the charging order before sending it to the charging stake. 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 electronic wallet of the user.

Therefore, by freezing the preset bill amount, smooth payment after the current charging can be ensured, and charging failure caused by insufficient balance in the electronic wallet to pay the amount of the current charging is avoided.

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

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

Specifically, since the charging order sent by the client is a charging order signed with the client private key and encrypted with the charging key, in step 108, the confirmation of the charging order may include:

carrying out signature verification on the charging order by using the public key of the client;

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

and confirming whether the data in the decrypted charging order is correct.

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

In the above step 109, after the end of the charging, the charging stake generates a charging bill, which may include a transaction serial number, charging stake information, client information, a charge amount, a charging period, a charging duration, a charging amount, and the like.

In step 110 described above, the charging stake transmits a charging bill to the client.

To ensure the security of the data transmission, before the step 110, the method may further include:

encrypting a charging bill by using a charging key;

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

step 110 may specifically include:

And sending the signed encrypted charging bill to the client.

After receiving a charging bill sent by a charging pile, signed by a charging pile private key and encrypted by the charging key, the client performs signature verification on the charging bill by using the charging pile public key; after the signature verification is passed, the client decrypts the charging bill by using the charging key; the client confirms whether the data in the decrypted charging bill is correct.

And when the client confirms that the data in the decrypted charging bill is correct, encrypting the bill confirmation information by using the charging key, signing the encrypted bill confirmation information by using a private key of the client, and sending the signed encrypted bill confirmation information to the charging pile.

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

The charging rule may be a charging rule preset by the charging pile, and may be calculated according to a charging unit price, a duration, a charging amount, and the like.

In addition, in the embodiment of the present invention, after the charging pile generates the charge bill corresponding to the charge settlement information, the charging pile may store the charge bill of the present charge and the corresponding charge settlement information into the security module SE of the charging pile, so as to ensure that the data cannot be stolen or lost.

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

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

Therefore, the embodiment of the invention can realize local point-to-point charging transaction settlement without passing through 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 that local related transaction records may be synchronized to the central platform in a suitable manner.

In step 113, in the case that the charging pile is online, the charging bill and the charge settlement information corresponding to the charging bill may be sent to the charging management platform, and the charging management platform may perform verification according to the charging bill and the charge settlement information corresponding to the charging bill sent by the charging pile and the client respectively, and after the verification passes, modify the account information corresponding to the client, so as to complete charging payment.

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

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