[0075] Figure 1 A schematic diagram of an application scenario of a charge and discharge control method provided in an embodiment of the present application. Figure 1As shown, the electric vehicle charging and discharging two-way interactive system may include a charging and discharging control system and an electric vehicle, wherein the charging and discharging control system may include a vehicle network management and control module, a charging and discharging interactive module and a charging and discharging device; exemplarily, the charging and discharging device may include but is not limited to a charging and discharging pile, a charging pile, etc., such as a V2G pile. It can be understood that the charging and discharging device in the embodiment of the present application may be a DC charging and discharging machine, such as a non-vehicle-mounted DC charging and discharging machine (complete vehicle).

[0076] Among them, the vehicle network control module is part of the two-way interactive network integration of electric vehicles and power grid charging and discharging, and is used to achieve efficient two-way energy flow between electric vehicles and power grids. The vehicle network control module has the functions of orderly charging and discharging management and control of electric vehicles, including but not limited to charging and discharging demand processing response, orderly charging and discharging strategy generation and issuance, charging and discharging monitoring, safety protection, and information interaction between systems.

[0077] Optionally, the V2G pile can have functions such as orderly charging and two-way metering.

[0078] Exemplarily, the process of two-way interaction between electric vehicles and the power grid in charging and discharging may include: the vehicle-grid control module sends a demand response instruction to the charging and discharging interaction module / user, the vehicle-grid control module / charging and discharging interaction module and the user conduct two-way interaction on the charging and discharging equipment, and after the user uses the client (such as a mobile phone APP or other user-end method) to submit the charging and discharging demand to the vehicle-grid control module / charging and discharging interaction module, the vehicle-grid control module / charging and discharging interaction module sends the request to the corresponding V2G pile for processing.

[0079] Among them, the client can be a user terminal (abbreviated as user terminal), such as a wireless terminal; the wireless terminal can be a device that provides voice and / or other business data connectivity to the user, or a handheld device with wireless connection function, or other processing equipment connected to a wireless modem. Exemplarily, the wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a wireless access network.

[0080] It can be understood that the vehicle network control module / charge and discharge interaction module can use 4G / 5G communication technology to interact with users, confirm the user's charging and discharging needs and start the corresponding charging and discharging operations. During the entire charging and discharging process, the vehicle network control module / charge and discharge interaction module can monitor the status of each link in real time and provide relevant information to users through an information feedback mechanism.

[0081] It should be noted that the vehicle network control module and the charge-discharge interaction module can be independent devices. By encapsulating the relevant capabilities into the charge-discharge interaction module, the charge-discharge operation-related business can be managed separately, and the integration of different platforms can be supported, thereby improving flexibility and agility. Optionally, the vehicle network control module can have the ability to interact independently with the charge-discharge equipment (such as V2G piles), thereby realizing the orderly charge-discharge strategy issuance, safety protection and other scenarios.

[0082] In the embodiments of the present application, grid-side demand response can improve the stability and efficiency of the power system. By combining demand response with V2G technology, the energy storage advantages of electric vehicles can be fully utilized. The vehicle-grid interactive data interaction scheme of the embodiments of the present application is conducive to the application of V2G technology. Among them, the present application clarifies the technical requirements and data interaction methods for the two-way interaction of charging and discharging between electric vehicles and power grids, as well as the interaction content and format between the charging and discharging interaction module and the vehicle-grid control module. It can be understood that the present application is applicable to the design, construction and operation of a two-way interactive data interaction system for charging and discharging between electric vehicles and power grids.

[0083] It should be noted that the beneficial effects brought about by the embodiments of the present application or the technical problems solved are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0084] Before introducing the specific embodiments of the present application, the professional terms involved in the present application are explained first:

[0085] Vehicle to grid (V2G) is a two-way interaction between electric vehicles and the power grid. The electric vehicle power battery is connected to the public power grid through a charging and discharging device (such as a charging and discharging device), and participates in the operation of the public power grid as an energy storage unit to achieve two-way energy flow.

[0086] Charging and discharging interactive module: The charging and discharging interactive module can provide users with charging and discharging management services in V2G scenarios, is responsible for managing charging and discharging stations and charging and discharging equipment, and supports the full process management of charging and discharging services in V2G operation scenarios.

[0087] Vehicle-grid control module: Provides technical support for the charge-discharge interaction module in the grid demand response, assists individuals who cannot participate independently to join through aggregation, and performs demand response on their behalf. The vehicle-grid control module is responsible for receiving the basic data and real-time data submitted by the charge-discharge interaction module, and interacts with the charge-discharge interaction module for power control instructions. At the same time, the vehicle-grid control module can receive demand response invitations issued by the power grid, including day-ahead invitations, intraday invitations, and real-time response business data, and collect response feedback data from the charge-discharge interaction module.

[0088] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0089] In an exemplary embodiment, Figure 2 As shown, a charge and discharge control method is provided, which is applied to Figure 1 The vehicle network control module in FIG. 1 is taken as an example to illustrate, including the following steps 202 to 204. Among them:

[0090] Step 202: Receive charging and discharging operation data of the charging and discharging device from the charging and discharging interactive module.

[0091] The charging and discharging operation data may be the operation data of the charging and discharging device, such as real-time power data related business data, etc.; the charging and discharging interaction module may receive the charging and discharging operation data sent by the charging and discharging device, and send the charging and discharging operation data to the vehicle network control module. Optionally, the charging and discharging device may be a V2G pile, and the charging and discharging operation data may be the V2G pile operation data.

[0092] Specifically, the embodiment of the present application clarifies the data interaction content between the vehicle network control module and the charge and discharge interaction module. For example, the charge and discharge operation data of the charge and discharge equipment can be used as the data interaction content or part of the data interaction content. Among them, the vehicle network control module can receive the charge and discharge operation data of the charge and discharge equipment through the charge and discharge interaction module; optionally, when the charge and discharge interaction module receives the charge and discharge operation data in real time, it can forward the charge and discharge operation data to the vehicle network control module in real time according to preset requirements (for example, technical requirements and data interaction methods, interaction content and format, etc.) to meet its demand response business data requirements.

[0093] Furthermore, the charging and discharging operation data can be understood as the response feedback data of the charging and discharging equipment to the grid-side demand. For example, the charging and discharging equipment can output the execution result according to the power control instruction issued by the vehicle network control module, and the charging and discharging interaction module can use the execution result as the response feedback data, and then the vehicle network control module collects the response feedback data of the charging and discharging interaction module.

[0094] Step 204: Determine whether the grid demand response is met based on the charging and discharging operation data.

[0095] Specifically, the vehicle-grid control module can determine whether the current grid demand response is met based on the charging and discharging operation data. It can be understood that the grid demand response can refer to the grid-side demand response. The embodiment of the present application combines the demand response with the V2G technology through the vehicle-grid control module, thereby giving full play to the energy storage advantages of electric vehicles, thereby providing a processing solution for the two-way interaction between electric vehicles and the grid charging and discharging (which can be referred to as the vehicle-grid interactive data interaction solution).

[0096] Exemplarily, the vehicle network control module can clarify the grid demand response according to the grid demand response invitation. It can be understood that the vehicle network control module can also clarify the grid demand response in other ways, not limited to the ways mentioned in the above embodiments, as long as the vehicle network control module can obtain the grid side demand response function.

[0097] In the above-mentioned charging and discharging control method, the vehicle-grid management and control module provides support for the charging and discharging interaction module in the grid demand response, wherein the electric vehicle power battery is connected to the public power grid through the charging and discharging equipment, and the charging and discharging interaction module can manage the charging and discharging stations and charging and discharging equipment, satisfying the two-way interaction of charging and discharging between the electric vehicle and the power grid and clarifying the data interaction method, thereby realizing the processing solution of the two-way interaction data of charging and discharging between the electric vehicle and the power grid.

[0098] In an exemplary embodiment, before step 202, the following steps may be included:

[0099] Send power control instructions to charging and discharging equipment.

[0100] Specifically, the embodiment of the present application clarifies the power control instruction interaction mode, wherein the vehicle network control module initiates a power control instruction for the charging and discharging device, and the power control instruction is used to instruct the charging and discharging device to participate in the demand response. Optionally, the charging and discharging device participating in the demand response needs to have a remote power control function.

[0101] In some examples, the power control instruction may include charging and discharging equipment information, power control parameters and a limited deadline. Exemplarily, based on the power control instruction, the vehicle network control module can actually control the charging power of the DC charger and discharger.

[0102] In one embodiment, sending a power control instruction to a charging and discharging device may include:

[0103] The power control command is sent to the charging and discharging equipment through the charging and discharging interactive module.

[0104] Specifically, the vehicle network management and control module can issue power control instructions through the charging and discharging interaction module or directly to the charging and discharging equipment (such as charging and discharging piles). If the charging and discharging equipment supports the power control function, it can respond to the power control instructions and feedback the execution results.

[0105] Furthermore, the power control function of the power control instruction corresponds to the data type of the power control instruction; wherein, the charging and discharging equipment participating in the demand response needs to have the remote power control function; taking the charging and discharging equipment as a charging pile as an example, if the charging pile does not support the power control function (such as the remote power control function), the vehicle network control module can provide a power control upgrade and transformation requirement document for upgrading and transforming the charging pile as needed. If the vehicle network control module determines that the execution accuracy or execution completion of the function does not meet the requirements of the vehicle network control module during the process of testing the power control function of the charging pile, it can instruct the charging pile to perform a power control upgrade and transformation.

[0106] Taking remote power control as an example, the power control instruction is used by the vehicle network control module to send power control instructions to the charging and discharging pile. In order to ensure that the vehicle network control module can actually realize the charging power control of the DC charger and discharger, the power control instruction can include the following content: charging point device number, charging and discharging interface number, power control parameters and charging and discharging time, where the charging and discharging time can represent a limited deadline (for example, the charging device can automatically cancel the restriction after exceeding this time). In one embodiment, the method can also include:

[0107] Obtain authorization to perform power control on the charging and discharging equipment from the charging and discharging interaction module.

[0108] Specifically, before sending the power control instruction, the vehicle network control module needs to obtain the power control authorization of the charge-discharge interaction module. Exemplarily, the vehicle network control module can obtain the authorization for power control of the charge-discharge device from the charge-discharge interaction module.

[0109] Alternatively, if Figure 3As shown, taking the example of the vehicle network control module sending the power control instruction to the charging and discharging device through the charging and discharging interaction module, after receiving the power control instruction, the charging and discharging interaction module can reply to the original content of the instruction to ensure that the instruction is received correctly and forwarded to the charging and discharging device in real time. After receiving the power control instruction, the charging and discharging device can reply the remote power control result to the charging and discharging interaction module, and the charging and discharging interaction module can forward the remote power control result to the vehicle network control module in real time. It can be understood that the charging and discharging operation data in the embodiment of the present application can include the above-mentioned remote power control result.

[0110] Among them, regarding the remote power control result, the data type of the remote power control result can be used for the vehicle network control module to receive the power control instruction execution result feedback. Optionally, in order to ensure that the vehicle network control module can grasp the execution result of the charging and discharging power control instruction of the DC charger in real time, the remote power control result can include the following: charging and discharging equipment number, charging and discharging interface number and power control result.

[0111] In one embodiment, before sending a power control instruction to a charging and discharging device, the process includes:

[0112] In response to receiving a demand response invitation from the power grid, a solicitation demand response execution phase is entered.

[0113] Specifically, when the vehicle network control module receives a demand response invitation from the power grid, it can enter the invitation demand response execution stage, and the invitation demand response execution stage can indicate that the vehicle network control module is in real-time and invitation demand response execution period.

[0114] Exemplarily, after the vehicle network control module obtains the power control authorization of the charge-discharge interaction module, during the execution of real-time and invitation demand response, the vehicle network control module initiates a power control instruction for the charge-discharge device.

[0115] In one embodiment, the demand response invitation may include a day-ahead invitation, an intra-day invitation, and demand response service data.

[0116] Specifically, the vehicle network management and control module can receive a demand response invitation issued by the power grid, which may include a day-ahead invitation, an intraday invitation and demand response business data, wherein the demand response business data may represent business data that requires a real-time response.

[0117] Exemplarily, the vehicle network control module can determine whether the grid demand response is met based on the demand response invitation and when the charging and discharging operation data of the charging and discharging equipment is obtained through the charging and discharging interaction module.

[0118] The above-mentioned charging and discharging control method, through a clear power control interaction method, the vehicle network management and control module can obtain the execution result of the charging and discharging equipment for the power control instruction through the charging and discharging interaction module. The execution result can be included in the charging and discharging operation data as the data interaction content or part of the data interaction content between the vehicle network management and control module and the charging and discharging interaction module, and then determine whether the grid side demand response is met, thereby realizing the orderly charging and discharging management and control function of the electric vehicle.

[0119] In an exemplary embodiment, the charging and discharging operation data may include real-time data; the real-time data is used to characterize the interaction content between the charging and discharging interaction module and the vehicle network control module regarding the charging and discharging equipment.

[0120] Specifically, based on the data interaction content between the vehicle network control module and the charge and discharge interaction module in the embodiment of the present application, it can be ensured that the vehicle network control module accurately and efficiently collects, monitors, predicts and controls the data of the charge and discharge interaction module. Exemplarily, the charge and discharge operation data as the data interaction content or a part of the data interaction content may include real-time data, which may be used to characterize the interaction content between the charge and discharge interaction module and the vehicle network control module regarding the charge and discharge equipment. For example, the real-time data may be divided into three categories according to the charge and discharge process of the V2G pile of the electric vehicle: charge and discharge start, charge and discharge process and charge and discharge end.

[0121] Optionally, the real-time data may be transmitted via a protocol such as MQTT (Message Queuing Telemetry Transport).

[0122] In one of the embodiments, the real-time data includes real-time data of the charging and discharging process, service data, device clock uplink data, and feedback content of the charging and discharging device in response to the power control instruction.

[0123] Specifically, real-time data may include real-time data of the charging and discharging process, business data, device clock uplink data, and feedback content of the charging and discharging device for power control instructions. Among them, the real-time data of the charging and discharging process can be used to instruct the vehicle network control module to monitor the real-time operating status of the charging and discharging device in real time. Business data can be data related to the charging and discharging business.

[0124] The device clock uplink data can be used for time synchronization between the vehicle network control module and the charging and discharging equipment, such as the time synchronization between the vehicle network control module and the DC charger and discharger. Exemplarily, the device clock uplink data may include the following content: the charging and discharging equipment number and the equipment time. Furthermore, the feedback content of the charging and discharging equipment for the power control instruction may refer to the execution result of the charging and discharging equipment for the power control instruction. In one embodiment, the power control instruction is used to perform remote power control on the charging and discharging equipment; the feedback content of the charging and discharging equipment for the power control instruction may include the remote power control result.

[0139] Among them, the real-time data can be divided into three categories according to the charging and discharging process of the electric vehicle V2G pile, namely, charging and discharging start, charging and discharging process, and charging and discharging end. Taking the charging process as an example, when charging is started through the vehicle VIN from the electric start, the interactive process is "charging authentication uplink-charging authentication downlink-vehicle identification authentication to start charging execution result", when charging through the vehicle charging card, the interactive process is "charging authentication uplink-charging authentication downlink", and when charging is started through mobile devices such as mobile phones, the interactive process is "remote start charging-remote start charging execution result". After the charging start is completed, the charging and discharging interactive module uploads the latest charging process uplink data and charging process real-time data to the vehicle network control module in real time. When the charging service ends normally, the charging and discharging interactive module shall send the collected charging and discharging record uplink data to the vehicle network control module. If the charging and discharging interactive module sends a remote termination charging instruction to the charging device, it shall also be forwarded to the vehicle network control module simultaneously.

[0140] In one of the embodiments, the real-time data of the charging and discharging process includes real-time electrical monitoring data of the off-vehicle DC charger and discharger and the operating status data of the charger and discharger equipment.

[0141] Specifically, the real-time data of the charging and discharging process may include the real-time electrical monitoring data of the DC charging and discharging machine and the operating status data of the charging and discharging machine equipment. In order to ensure that the vehicle network control module monitors the real-time operating status of the charging and discharging pile in real time, the real-time data of the charging and discharging process may include the following: charging and discharging equipment number, charging and discharging interface number, charging and discharging machine output voltage, charging and discharging machine output current, SOC and charging and discharging machine status.

[0143] It should be noted that the present application also proposes a data interaction method between the vehicle network control module and the charging and discharging equipment. Exemplarily, the data interaction method between the vehicle network control module and the charging and discharging equipment may include: the charging and discharging equipment involved in the charging and discharging startup process sends the device clock uplink data and the charging and discharging authentication uplink data to the vehicle network control module, and then the vehicle network control module sends the remote start charging and discharging and the charging and discharging authentication downlink data to the charging and discharging equipment, and the charging and discharging equipment can feedback the remote start charging and discharging execution results and the vehicle identification authentication start charging and discharging execution results. Furthermore, it also includes the charging and discharging equipment involved in the charging and discharging process sending the charging and discharging process uplink data and the charging and discharging process real-time data to the vehicle network control module. And the vehicle network control module involved in the charging and discharging end process sends the remote termination discharge to the charging and discharging equipment, and the charging and discharging equipment feeds back the charging and discharging record uplink data.

[0144] The specific description of the above-mentioned related data can be found in the previous text, which will not be repeated here. It can be understood that the vehicle network control module can have the ability to interact independently with the charging and discharging equipment, and can be applied to the orderly charging and discharging strategy issuance, safety protection and other scenarios.

[0145] In an exemplary embodiment, the method may further include:

[0146] Receive basic data from the charge-discharge interaction module; the basic data is used by the vehicle network control module to manage the charge-discharge equipment and each charge-discharge interaction module.

[0147] Specifically, regarding the data interaction method between the vehicle network control module and the charge and discharge interaction module, the embodiment of the present application also proposes a basic data interaction method, wherein the charge and discharge interaction module transmits basic data to the vehicle network control module to meet its demand response business data requirements.

[0148] Exemplarily, the basic data can be used to assist the vehicle network control module in managing the charging and discharging station information of each charging and discharging interactive module and the real-time data of the charging and discharging equipment.

[0149] In one embodiment, the basic data may include at least one of charging and discharging station information, charging and discharging equipment information, charging and discharging gun information, and charging and discharging interactive module registration information.

[0150] Specifically, Figure 4 As shown, the charge-discharge interaction module can transmit the information of the charge-discharge station, charge-discharge equipment (e.g., V2G pile), and charge-discharge gun to the vehicle network control module. Exemplarily, the charge-discharge station information may include: the charge-discharge station number, the charge-discharge station name, the power supply line, the voltage level, the power supply capacity, the number of charge-discharge piles, and the operation information, address information, asset information, and price information.

[0151] Exemplarily, the charging and discharging equipment information may include equipment ID (e.g., charging and discharging machine number), charging and discharging pile number (e.g., equipment number of the charging and discharging station where the charging and discharging equipment is located), associated station number, equipment operating status, charging and discharging equipment type (e.g., DC equipment, AC equipment, or AC / DC integrated equipment, etc.), number of charging and discharging guns, rated power, set output power, battery state of charge (SOC), equipment temperature, and equipment properties (e.g., dedicated or public).

[0152] Optionally, the charge-discharge gun information may include the charge-discharge gun number. Exemplarily, the registration information of the charge-discharge interaction module may include network information, interface information, and charge-discharge station, pile, gun basic data interface address, etc.

[0153] In one embodiment, the method may further include:

[0154] In response to receiving the authentication information sent by the charge-discharge interactive module after the registration is completed, a signature key is sent to the charge-discharge interactive module.

[0155] Specifically, regarding the data interaction method between the vehicle network control module and the charge and discharge interaction module, the embodiment of the present application also proposes a charge and discharge interaction module registration and data authentication interaction method, wherein the prerequisite for the charge and discharge interaction module and the vehicle network control module to realize data interaction includes completing the following three steps: charge and discharge interaction module registration, completion of authentication information, and completion of data signature.

[0156] Among them, Figure 5 As shown, regarding the registration interaction method of the charge-discharge interaction module, the charge-discharge interaction module can complete relevant registration work before connecting to the vehicle network control module, such as providing the charge-discharge interaction module registration information to the vehicle network control module.

[0157] like Figure 6As shown, regarding the authentication information interaction method of the charge-discharge interaction module, the authentication information of the charge-discharge interaction module may refer to a key (SigSecret) that the charge-discharge interaction module needs to obtain from the vehicle network control module after completing the registration. The key is mainly used by the vehicle network control module to securely identify and authenticate the charge-discharge interaction module. Before each charge-discharge interaction module obtains an independent key, it is necessary to fill in the authentication message in the vehicle network control module. After the review is passed, the platform assigns a key (SigSecret) to the charge-discharge interaction module. After the vehicle network control module passes the authentication review, the key (SigSecret) assigned by the charge-discharge interaction module according to the platform authentication address is used to sign the data during the information interaction process with the vehicle network control module.

[0158] Furthermore, regarding the data signature method, after completing the registration and authentication information, the charging and discharging interaction module has obtained the key used to identify and authenticate itself, and subsequently realizes data interaction with the vehicle network control module. It can encrypt all interactive data content based on its own key, and then form a data signature for the secure transmission of data between the charging and discharging interaction module and the vehicle network control module.

[0159] In one of the embodiments, the network transmission mode between the vehicle network control module and the charging and discharging interaction module includes one or more of the following: a charging service protocol network transmission mode and an MQTT protocol network transmission mode.

[0160] Specifically, the present application also proposes a network transmission mode between the charging and discharging interaction module and the vehicle network control module, wherein the network transmission mode may refer to a network transmission mode between the vehicle network control module and the charging and discharging interaction module. Exemplarily, the network transmission mode may include one or more of the following: a charging service protocol network transmission mode and an MQTT protocol network transmission mode.

[0161] In one embodiment, the charging service protocol network transmission mode may use the Transmission Control Protocol (TCP).

[0162] Specifically, regarding the charging service protocol network transmission mode, the communication between the charging and discharging interaction module and the charging and discharging equipment (such as V2G piles) can adopt the reliable transmission protocol TCP of the network transmission layer. Among them, the charging and discharging interaction module can be a TCP server, and the charging and discharging equipment can be a TCP client. Furthermore, the communication between the charging and discharging interaction module and the vehicle network control module can adopt the reliable transmission protocol TCP of the network transmission layer, the vehicle network control module is the TCP server, and the charging and discharging interaction module is the TCP client. Among them, the charging and discharging interaction module is configured with a protocol docking service for interacting with the charging and discharging equipment, and the vehicle network control module can be configured with a power control service for message transmission with the protocol docking service.

[0163] In addition, regarding the MQTT protocol network transmission mode, taking the charging and discharging device as a V2G pile as an example, after the V2G pile communicates with the server through the protocol stack, the real-time data message can be written into the message queue (MQ) of the V2G pile charging and discharging interactive module in real time; after the deployed transit server reads the MQ, it is forwarded to the MQ of the server of the vehicle network control module in the form of a message; when the vehicle network control module (power control service) issues an instruction, the message will be written into the MQ of the server of the vehicle network control module, and the charging and discharging interactive module (protocol docking service) actively reads and sends it to the protocol stack, and finally the protocol stack sends it to the V2G pile. Among them, the charging and discharging interactive module is configured with a first message queue (MQ) and a protocol docking service for interacting with the charging and discharging device, and the vehicle network control module can be configured with a second message queue (MQ) and a power control service, the power control service can transmit messages with the second message queue (MQ), and then the second message queue (MQ) and the first message queue (MQ) transmit messages, and the first message queue (MQ) can transmit messages with the protocol docking service.

[0167] Step 304, sending the charging and discharging operation data to the vehicle network control module; the charging and discharging operation data is used to instruct the vehicle network control module to determine whether the grid demand response is met.

[0168] Specifically, the charge-discharge interaction module sends the charge-discharge operation data to the vehicle-grid control module, and then the vehicle-grid control module can determine whether the grid demand response is met based on the charge-discharge operation data.
