[0003] With the rapid development of electric vehicle charging networks, more and more charging operators have their own charging networks. In order to provide customers with more convenient charging services, various operators can interconnect and enable customers of one operator to charge on the charging networks of multiple operators, which greatly improves customer experience and has a positive impact on the promotion of electric vehicles.

[0004] At present, the interconnection of charging operators is basically to build an interconnection interface for two (or more) operators that need to interconnect, so as to achieve their respective interconnection. When charging across operator platforms through this method, multiple interactions between the central platforms of two (or more) operators through the interconnection interface are required to complete.

[0065] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0066] In the description of this specification, the terms "include", "including", "have", "contain", etc. are all open terms, which mean including but not limited to. The descriptions with reference to the terms "one embodiment", "a specific embodiment", "some embodiments", "for example", etc. mean that the specific features, structures or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be appropriately adjusted as needed.

[0067] At present, the interconnection and interoperability of charging operators is basically based on the specification of "T / CEC 102.1-2016 Electric Vehicle Charging and Battery Swapping Service Information Exchange" and the interconnection and interoperability of the operators' respective central platforms. The existing technology connects the Iserv, Icomm and Ipay interfaces of the central platforms of two (or more) operators to achieve interconnection and interoperability. For example, when a user of operator A charges in the charging network of operator B, the user's identity authentication information will be transmitted to the central platform of operator B through the network of operator B, and then the central platform of operator B will send the user's identity authentication information to the central platform of operator A through the interconnection interface. After the authentication of the central platform of operator A is passed, it will be fed back to the central platform of operator B, and the central platform of operator B will control the start and stop of charging. When charging is completed, the central platform of operator B completes the billing and settles with the central platform of operator A through the interconnection interface.

[0068] The study found that the interconnection solutions of the above operators have the following shortcomings based on the actual operation results:

[0069] 1. To complete a charging process, multiple interactions are required between the central platforms of two (or more) operators, and the response speed is slow. When the business volume of the operator's central platform is large, the interconnection interface can easily become a bottleneck for the entire business.

[0070] 2. When the network of the central platform or charging pile is unstable, it is easy to cause the interconnection interface interaction to fail, so that customers cannot complete charging and the customer experience is poor.

[0071] 3. The needs of various operators vary. Although there are reference industry specifications, when actually connecting interconnection interfaces, operators often add personalized content based on industry specifications, which makes interface development and connection work time-consuming, labor-intensive and costly.

[0072] In response to the above problems, the embodiments of the present invention provide a method and device for cross-operator platform charging payment for electric vehicles, which can make the cross-operator platform charging process unaffected by the network environment and business volume, achieve more economical and efficient interconnection, and reduce the difficulty and cost of interconnection among charging operators while ensuring customer experience.

[0073] like Figure 1 As shown, it is a flow chart of a method for charging and paying for an electric vehicle across operator platforms provided by an embodiment of the present invention, which is applied to a first charging pile, and the first charging pile is a charging pile of a first operator. The method may include the following steps:

[0074] Step 101: receiving a near field communication connection request sent by a second client, and establishing a near field communication connection with the second client according to the near field communication connection request, where the second client is a client of a second operator;

[0075] Step 102: Receive cross-operator platform charging request information sent by the second client;

[0076] Step 103: Perform charging compliance verification on the cross-operator platform charging request information;

[0077] Step 104: Send the charging compliance verification result to the second client, so that the second client generates a charging order after the charging compliance verification passes, wherein the charging order includes charging pile information, client information, preset charging amount, preset charging time and preset charging amount;

[0078] Step 105: receiving a charging order sent by a second client;

[0079] Step 106: Verify the data of the charging order;

[0080] Step 107: After the data in the charging order is confirmed to be correct through data verification, the charging mode is started to charge according to the charging order;

[0081] Step 108: after charging is completed, a charging bill is generated, the charging bill including charging pile information, client information, charging amount, charging time period, charging duration and charging amount;

[0082] Step 109: Send the charging bill to the second client, so that the second client sends the charging bill to the charging management platform of the second operator;

[0083] Step 110: Send the charging bill to the charging management platform of the first operator, so that the charging management platform of the first operator and the charging management platform of the second operator complete the charging payment according to the charging bill.

[0084] Compared with the technical solution of completing charging across operator platforms through an interconnection interface in the prior art, in the embodiment of the present invention, a point-to-point local connection is established between the charging pile of the first operator and the client of the second operator through near-field communication, so as to realize user authentication and billing process in the cross-operator charging process. The operator's charging management platform only performs charging payment, which greatly reduces the dependence on the charging management platform during cross-operator charging, and also reduces the impact of network quality on the charging process, thereby improving charging efficiency and providing users with a better charging experience. At the same time, by establishing a local connection between the client and the charging pile through near-field communication, the development difficulty and cost of interconnection between the charging management platforms of each operator are greatly reduced, which is conducive to the rapid promotion of charging across operator platforms.

[0085] In the embodiment of the present invention, during the charging process of electric vehicles across operator platforms, the security of charging data transmission also needs to be considered. Specifically, the embodiment of the present invention adopts the key mechanism of the trusted certification body IBC (Identity-Based Cryptograph) to ensure the security of data transmission. Specifically, IBC uses an asymmetric cryptographic system, and encryption and decryption use two different sets of keys. The public key of each user is his identity, such as email address, telephone number, etc. The private key is controlled by the user himself in the form of data, and the key management is quite simple, and data information can be easily encrypted and decrypted.

[0086] In the embodiment of the present invention, the charging piles of each operator and the clients (Apps) of each operator can download the identity authentication information (public key and private key of IBC) locally from the trusted authentication agency.

[0087] In one embodiment of the present invention, in order to ensure the security of data transmission, before the above step 102, the following steps may also be included:

[0094] In one embodiment of the present invention, the cross-operator platform charging request information may include: user identity information and user historical charging records. Therefore, the above step 103 may specifically include:

[0095] Check whether the customer to which the second client belongs is included in the blacklist and / or whether there is any unpaid charging record.

[0096] In this way, users who do not comply with regulations can be prevented from charging across platforms, thus avoiding losses to charging operators.

[0097] In one embodiment of the present invention, in order to ensure the data security of the charging compliance verification result, before the above step 104, the following may also be included:

[0098] Encrypting the charging compliance verification result using the second client public key;

[0106] The above step 109 may specifically include:

[0107] The charging bill encrypted with the second client's public key is sent to the second client.

[0108] like Figure 2As shown, it is a flowchart of another electric vehicle cross-operator platform charging payment method provided by an embodiment of the present invention, which is applied to a second client, and the second client is a client of a second operator. The method may include the following steps:

[0109] Step 201, sending a near field communication connection request to a first charging pile, so that the first charging pile establishes a near field communication connection with a second client according to the near field communication connection request, wherein the first charging pile is a charging pile of a first operator;

[0110] Step 202, sending a cross-operator platform charging request message to the first charging pile;

[0111] Step 203, receiving a charging compliance verification result of the first charging pile on the cross-operator platform charging request information;

[0112] Step 204, if the charging compliance check passes, generating a charging order, the charging order including charging pile information, client information, preset charging amount, preset charging time and preset charging amount;

[0113] Step 205, sending the charging order to the first charging pile, so that the first charging pile performs data verification on the charging order, and when the data in the charging order is confirmed to be correct through data verification, charging is performed according to the charging order, and a charging bill is generated;

[0115] Step 207: Send the charging bill to the charging management platform of the second operator, so that the charging management platform of the second operator and the charging management platform of the first operator complete the charging payment according to the charging bill.

[0116] In the embodiment of the present invention, during the charging process of electric vehicles across operator platforms, the security of charging data transmission also needs to be considered. Specifically, the embodiment of the present invention adopts the key mechanism of the trusted certification body IBC (Identity-Based Cryptograph) to ensure the security of data transmission. Specifically, IBC uses an asymmetric cryptographic system, and encryption and decryption use two different sets of keys. The public key of each user is his identity, such as email address, telephone number, etc. The private key is controlled by the user himself in the form of data, and the key management is quite simple, and data information can be easily encrypted and decrypted.

[0117] In the embodiment of the present invention, the charging piles of each operator and the clients (Apps) of each operator can download the identity authentication information (public key and private key of IBC) locally from the trusted authentication agency.

[0118] In the embodiment of the present invention, before the above step 202, the following steps may also be included:

[0119] Sending a second client public key to the first charging pile, where the second client public key is downloaded in advance by the second client from a trusted certification authority IBC;

[0120] A first charging pile public key sent by the first charging pile is received, where the first charging pile public key is downloaded in advance by the first charging pile from a trusted certification body IBC.

[0121] Among them, the above-mentioned second client public key can be used by the first charging pile to encrypt charging data; the above-mentioned first charging pile public key can be used by the second client to encrypt charging data.

[0122] In one embodiment of the present invention, data can be stored through the storage mechanism of the security module SE to ensure data security. Therefore, before the above step 202, the following may also be included:

[0145] 2. The second client sends the second client public key to the first charging pile.

[0146] Here, after the second client receives the information that the near field communication connection is successful fed back by the first charging pile, the second client public key may be sent to the first charging pile.

[0147] 3. The first charging pile sends the first charging pile public key to the second client.

[0148] 4. The second client obtains the user authentication information from the security module SE and generates cross-operator platform charging request information, and the cross-operator platform charging request information carries the user authentication information.

[0149] It should be noted that the user authentication information may be the user's historical charging records.

[0150] 5. The second client uses the first charging pile public key to encrypt the cross-operator platform charging request information.

[0151] 6. The second client sends the cross-operator platform charging request information encrypted with the public key of the first charging pile to the first charging pile.

[0152] 7. The first charging pile uses the first charging pile private key to decrypt the cross-operator platform charging request information.

[0153] 8. The first charging pile performs a charging compliance check on the decrypted cross-operator platform charging request information to obtain a check result.

[0154] Here, the charging compliance check may include checking whether the customer to which the second client belongs is included in the blacklist, and / or whether there is an unpaid charging record.

[0155] 9. The first charging pile uses the second client public key to encrypt the charging compliance verification result;

[0156] 10. The first charging pile sends the charging compliance verification result encrypted with the second client's public key to the second client.

[0157] 11. The second client uses the second client private key to decrypt the charging compliance verification result to obtain the charging compliance verification result.

[0158] 12. When the charging compliance check is passed, the second client generates a charging order, which includes charging pile information, client information, preset charging amount, preset charging time and preset charging amount.

[0159] 13. The second client uses the first charging pile public key to encrypt the charging order;

[0160] 14. The second client sends the charging order encrypted with the public key of the first charging pile to the first charging pile.

[0161] 15. The first charging pile uses the first charging pile private key to decrypt the charging order and perform data verification on the charging order.

[0162] 16. After the first charging pile confirms that the data in the charging order is correct through data verification, it starts charging mode and charges according to the charging order;

[0163] 17. After charging is completed, the first charging pile generates a charging bill, which includes charging pile information, client information, charging amount, charging time period, charging duration and charging amount.

[0164] 18. The first charging pile uses the second client public key to encrypt the charging bill.

[0165] 19. The first charging pile sends the charging bill encrypted with the public key of the second client to the second client;

[0166] 20. The second client uses the second client private key to decrypt the charging bill.

[0167] 21. When the charging bill is correct, the second client sends the charging bill to the charging management platform of the second operator.

[0168] Here, the charging bill may be sent to the charging management platform of the second operator when the second client confirms that the data in the charging bill is correct. At the same time, the second client may also send a response message to the first charging pile that the data in the charging bill is correct.

[0169] It should be noted that this can only be completed when the network connection between the second client and the charging management platform of the second operator is normal.

[0170] 22. The first charging pile sends the charging bill to the charging management platform of the first operator.

[0171] Here, after the first charging pile receives the response information indicating that the data in the charging bill of the second client is correct, the charging bill may be sent to the charging management platform of the first operator.

[0172] It should be noted that this can only be completed when the network connection between the first charging pile and the charging management platform of the first operator is normal.

[0173] 23. The charging management platform of the first operator and the charging management platform of the second operator complete the charging payment according to the charging bill.
