Description

Discharge control method and related device

[0001] The present application claims priority to Chinese application No. 202410685515.3, filed on May 29, 2024, entitled "Discharge control method and related device", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] Embodiments of the present application relate to, but are not limited to, the field of vehicle-to-grid (V2G) technology, and in particular to a discharge control method and related device. BACKGROUND

[0003] The rapid development of modern social economy has led to a sustained increase in electricity consumption in all aspects, especially during the summer and winter peak load periods of the power grid, the peak-valley difference of major power grids is increasing, and the lack of standby capacity on the power generation side causes difficulty in peak scheduling of the power grid, which easily leads to power supply shortages in some areas, and even large-scale power grid blackouts, causing significant losses and impacts on social production and people's lives.

[0004] With the explosion of new energy technology and the change in consumers' attitude towards new energy vehicles, the sales of new energy vehicles have increased year by year and are favored by consumers in the automobile market. Since new energy vehicles are usually equipped with high-capacity batteries, which are very good energy storage media. If, in addition to meeting the basic needs of new energy vehicle users, the high-capacity batteries of new energy vehicles are used as a buffer for the power grid and renewable energy, i.e., vehicle-to-grid (V2G) discharge technology emerges as the times require. For example, when the power grid load is too high, the high-capacity batteries of new energy vehicles can discharge to the power grid to reduce the load pressure of the power grid, and when the power grid load is low, the excess power generation of the power grid can be stored to avoid waste and achieve the effect of peak shaving. TECHNICAL SOLUTION

[0005] Embodiments of the present application provide a discharge control method and related device, which can allocate a discharge task to a discharge vehicle, and the discharge vehicle discharges to a charging pile based on the discharge task, which can improve the management and control capability of the discharge work of the V2G charging pile and the new energy vehicle, and also improve the measurement accuracy of the discharge capacity in the V2G discharge process.

[0006] In a first aspect, embodiments of the present application provide a discharge control method, which comprises:

[0007] allocating a discharge task to a discharge vehicle;

[0008] the discharge vehicle is a vehicle that opens the vehicle-to-grid (V2G) discharge function;

[0009] the discharge vehicle is electrically connected to a charging pile; and

[0010] The discharge task is used to instruct the discharge vehicle to discharge to the charging station.

[0011] In this embodiment, a discharge task can be assigned to the discharge vehicle, which then discharges to the charging pile based on the task. This can improve the control over the discharge operation of V2G charging piles and new energy vehicles, and also improve the accuracy of discharge measurement during V2G discharge.

[0012] In one possible implementation of the first aspect, the method further includes:

[0013] Acquire discharge data from the vehicle performing the discharge task and charging pile data; and

[0014] The execution status of the discharge task is monitored based on discharge data and charging pile data.

[0015] In the above embodiments, the execution status of the discharge task of the discharging vehicle can be monitored based on the discharge data of the discharging vehicle and the charging pile data. This improves the control over the discharge operation of V2G charging piles and new energy vehicles, and also enhances the accuracy of discharge measurement during V2G discharge. For example, when the execution status of the discharge task becomes abnormal, the discharging vehicle can be promptly notified to withdraw from the discharge task, reducing losses for the vehicle owner and preventing the owner from reducing their enthusiasm for discharging to the grid due to loss of income. Furthermore, when the number of discharging vehicles with abnormal discharge task execution status reaches a certain threshold, the management personnel of the discharge service are notified that the charging pile may be malfunctioning and requires timely maintenance, thereby minimizing the probability of discharge failure for the vehicle owner.

[0016] In yet another possible implementation of the first aspect, the method further includes:

[0017] In response to an anomaly in the execution status of the discharge mission, the discharge vehicle is instructed to withdraw from the discharge mission.

[0018] For example, if an abnormality occurs in the execution status of a discharge task, the discharge vehicle should be notified in a timely manner to withdraw from the discharge task, thereby reducing the losses of the discharge vehicle owner and preventing the discharge vehicle owner from reducing their enthusiasm for discharging to the grid due to loss of income.

[0019] In yet another possible implementation of the first aspect, the method further includes:

[0020] In response to an abnormality in the execution status of the discharge task, a first message is sent to the first device, which indicates that the discharge function is experiencing abnormal fluctuations.

[0021] For example, when the execution state of the discharging task appears abnormal, the manager of the discharging service is informed that the discharging function appears abnormal fluctuation, and the abnormal fluctuation needs to be eliminated in time to ensure the normal execution of the discharging task and to reduce the probability of discharging failure encountered by the discharging vehicle owner as much as possible.

[0022] In a further possible implementation form of the first aspect, the method further comprises:

[0023] receiving second information from the first device, the second information being used to indicate whether the abnormal fluctuation is eliminated; and

[0024] in response to the second information indicating that the abnormal fluctuation is not eliminated, sending third information to the discharging vehicle, the third information being used to instruct the discharging vehicle to quit the discharging task and / or the third information being used to indicate that the discharging vehicle is malfunctioning.

[0025] For example, when the abnormal fluctuation is not eliminated, the discharging vehicle is informed in time to quit the discharging task, the loss of the discharging vehicle owner is reduced, and the enthusiasm of the discharging vehicle owner for discharging to the power grid is avoided to be reduced due to the loss of income. For another example, when the abnormal fluctuation is not eliminated, the discharging vehicle owner is informed in time that the discharging vehicle can malfunction, and the discharging vehicle needs to be maintained in time to reduce the probability of discharging failure encountered by the discharging vehicle owner as much as possible.

[0026] In a further possible implementation form of the first aspect, the execution state of the discharging task appearing abnormal comprises one or more of the following:

[0027] a deviation value between the discharging data and the charging pile data is greater than or equal to a first error threshold; and

[0028] a number of times that the deviation value between the discharging data and the charging pile data is greater than or equal to a second error threshold reaches an abnormal number threshold.

[0029] In the above implementation form, when the deviation value between the discharging data and the charging pile data is too large, it is considered that the execution state of the discharging task appears abnormal, so as to inform the discharging vehicle owner in time to reduce the loss of the owner. Further, when the number of times that the deviation value between the discharging data and the charging pile data is too large is too large, it is considered that the execution state of the discharging task appears abnormal, which can improve the accuracy of monitoring the execution state of the discharging task, so as to inform the discharging vehicle owner in time to reduce the loss of the owner.

[0030] In a further possible implementation form of the first aspect, the method further comprises:

[0031] updating a number of abnormal discharging vehicles, the abnormal discharging vehicle being a discharging vehicle whose execution state of the discharging task appears abnormal when discharging to the charging pile.

[0032] Therefore, the number of abnormal discharging vehicles is updated in time, so that whether the charging pile is faulty can be determined according to the number of abnormal discharging vehicles, and the charging pile can be maintained in time, thereby reducing the probability of discharging failure of the discharging vehicle owner as much as possible.

[0033] In a further possible implementation of the first aspect, the method further includes:

[0034] updating an abnormal discharging task indication, the abnormal discharging task indication being used to indicate a number of discharging tasks in which an execution state of the discharging task is abnormal.

[0035] Therefore, the number of discharging tasks that abnormally exit is updated in time, so that whether the charging pile is faulty can be determined according to the number of discharging tasks that abnormally exit, and the charging pile can be maintained in time, thereby reducing the probability of discharging failure of the discharging vehicle owner as much as possible.

[0036] In a further possible implementation of the first aspect, the method further includes:

[0037] sending fourth information to the charging pile in response to the number of abnormal discharging vehicles reaching a number threshold;

[0038] the fourth information being used to indicate that the charging pile is faulty;

[0039] the abnormal discharging vehicle being a discharging vehicle in which an execution state of the discharging task is abnormal when discharging to the charging pile.

[0040] Therefore, when the number of abnormal discharging vehicles reaches the number threshold, the manager of the discharging service is informed that the charging pile is possibly faulty, and the charging pile needs to be maintained in time, thereby reducing the probability of discharging failure of the discharging vehicle owner as much as possible.

[0041] In a further possible implementation of the first aspect, assigning the discharging task to the discharging vehicle includes:

[0042] assigning the discharging task to the discharging vehicle in response to determining that the discharging qualification of the discharging vehicle is passed.

[0043] In a further possible implementation of the first aspect, the method further includes:

[0044] performing a short-time discharging test on the discharging vehicle by the charging pile;

[0045] obtaining first test data of the discharging vehicle and second test data of the charging pile; and

[0046] determining that the discharging qualification of the discharging vehicle is passed in response to a test error between the first test data and the second test data being less than a third error threshold.

[0047] In a further possible implementation form of the first aspect, the method further comprises:

[0048] performing a short-time discharge test on the discharge vehicle via the charging pile again in response to the first test data and the second test data being greater than the third error threshold;

[0049] until the test error of the discharge vehicle during the short-time discharge test is less than the third error threshold or the number of tests reaches a test threshold;

[0050] the number of tests is a number of times of performing the short-time discharge test on the discharge vehicle via the charging pile; and

[0051] in response to the test error of the discharge vehicle during the short-time discharge test being less than the third error threshold, determining that the discharge qualification of the discharge vehicle is passed.

[0052] In the above implementation form, the discharge vehicle is assigned the discharge task only when it is determined that the discharge qualification of the discharge vehicle is passed, thereby reducing frequent impacts on the power grid caused by vehicles that do not meet the conditions randomly joining and / or exiting the discharge task.

[0102] Some terms in the embodiments of the present application will be described below.

[0103] Vehicle to grid (V2G) technology refers to a technology that electric vehicles send power to the power grid. The core idea is to use the storage energy of a large number of new energy vehicles as a buffer for the power grid and renewable energy. For example, when the power grid load is too high, the high-capacity battery of the new energy vehicle discharges to the power grid to reduce the load pressure of the power grid, and when the power grid load is low, it is used to store the excess power generation of the power grid to avoid waste and achieve the effect of peak load shifting. In this way, through V2G, the problems of low power grid efficiency and renewable energy fluctuation can be alleviated, and through V2G, new energy vehicle users can buy electricity from the power grid when the power grid price is low, and sell electricity to the power grid when the power grid price is high, thereby earning a price difference and creating a profit for new energy vehicle users.

[0104] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0105] The system architecture to which the embodiments of the present application are applied will be described below. It should be noted that the system architecture and business scenarios described in the present application are used to more accurately identify the technical solutions of the present application and do not constitute a limitation on the technical solutions provided by the present application. Those skilled in the art can know that as the system architecture evolves and new business scenarios appear, the technical solutions provided by the present application are also applicable to similar technical problems.

[0106] Please refer to FIG. 1, which is an architecture schematic diagram of a discharging system provided by an embodiment of the present application. As shown in FIG. 1, the discharging system includes a server 10, a charging pile 20, and a vehicle 30. Further, the discharging system also includes a power grid information center 40 and a first device 50.

[0107] The server 10 is a device with centralized computing power. Optionally, the server 10 can be a physical device such as a server or a host, etc., or a virtual device such as a virtual machine or a container, etc. Optionally, the server 10 can also be a cloud, such as a single service of the cloud or a server cluster composed of multiple servers, or a local device, such as a single service of the local or a server cluster composed of multiple servers. Illustratively, the server 10 can assign a discharging task to the vehicle 30. Further illustratively, the server 10 can monitor the execution status of the discharging task according to the discharging data when the vehicle 30 executes the discharging task and the electric pile data of the charging pile 20. Further illustratively, the server 10 can also instruct the vehicle 30 to exit the discharging task when the execution status of the discharging task appears abnormal.

[0108] Further, the server 10 can also have a communication capability. Illustratively, the server 10 can communicate with the vehicle 30, send information to the vehicle 30 and / or receive information from the vehicle 30. For example, the server 10 can obtain the discharge data of the vehicle 30 when performing the discharge task, and send third information to the vehicle 30. The third information is used to instruct the vehicle 30 to exit the discharge task and / or the third information is used to indicate that the vehicle 30 has a fault. Further illustratively, the server 10 can communicate with the charging pile 20, send information to the charging pile 20 and / or receive information from the charging pile 20. For example, the server 10 can receive the pile data from the charging pile 20, and send fourth information to the charging pile 20. The fourth information is used to indicate that the charging pile 20 has a fault.

[0109] The charging pile 20 is a discharge device for providing energy supplement for the electric vehicle or a charging device for receiving the electric energy transmitted by the electric vehicle, can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, can charge various models of electric vehicles according to different voltage levels, and can also receive the electric energy transmitted by various models of electric vehicles. Optionally, the charging pile 20 can include a second power supply connection interface 201. The second power supply connection interface 201 can be a device that can connect the electric transmission line to the power supply or the electric vehicle power supply equipment, and can also be a device that can connect the electric transmission line to the charging equipment for charging. The power supply connection interface is usually in pairs when electrically connected, for example, the second power supply connection interface 201 can be a female end (or called a socket), which can be coupled with a male end (or called a plug) to achieve electrical connection. Conversely, when the second power supply connection interface 201 is a male end, it is coupled with the corresponding female end.

[0110] Further, the charging pile 20 can also have a communication capability. Illustratively, the charging pile 20 can communicate with the server 10, send information to the server 10 and / or receive information from the server 10. For example, the charging pile 20 can send the pile data of the charging pile 20 to the server 10, and receive the fourth information from the server 10.

[0111] The vehicle 30 is a vehicle driven by electric energy. Exemplarily, the vehicle can be a new energy vehicle, such as a pure electric vehicle, a range-extended electric vehicle, a hybrid electric vehicle, a fuel cell electric vehicle, etc. Optionally, the vehicle 30 can further include a first power supply connection interface 301. The first power supply connection interface 301 can be a device for charging the vehicle 30 after being connected with the second power supply connection interface 201, and the first power supply connection interface 301 can also be a device for discharging the vehicle 30 after being connected with the second power supply connection interface 201. For example, the first power supply connection interface 301 can be a male end (or referred to as a plug), which can be coupled with a female end (or referred to as a socket, such as the second power supply connection interface 201) to achieve electrical connection. Optionally, the vehicle 30 can further include an on-board charger (OBC), which is a device capable of converting power meeting the power grid into direct current required by the on-board energy storage device (such as a battery) to charge the on-board energy storage device, and also capable of converting the power in the on-board energy storage device into alternating current meeting the requirements of the power grid to transmit the power to the power grid.

[0112] Further, the vehicle 30 can also have communication capability. Exemplarily, the vehicle 30 can communicate with the server 10 to send information to the server 10 and / or receive information from the server 10. For example, the vehicle 30 can send discharge data of the vehicle 30 performing the discharging task to the server 10, and receive third information from the server 10. Further, the vehicle 30 can also have processing capability. Exemplarily, the vehicle 30 can obtain the discharging task assigned by the server 10, and control the vehicle 30 to discharge to the charging pile 20 according to the discharging task.

[0113] The power grid information center 40 is used for power transmission with the charging pile 20. Exemplarily, the power grid information center 40 can send a discharging instruction to the server 10, indicating that a discharging vehicle is required to transmit power to the power grid.

[0114] The first device 50 is a device used by an operator to send discharging benefits to a user of a discharging vehicle and to obtain benefits from charging the discharging vehicle. Optionally, the first device 50 can also be a device used by a manager of a discharging service. The first device 50 can communicate with the server 10 to manage the charging work and the discharging work of the charging pile 20 through the server 10. Exemplarily, the first device 50 can send a discharging instruction to the server 10, indicating that a discharging vehicle is required to transmit power to the power grid.

[0115] In a possible implementation, the server 10 establishes a communication connection with the vehicle 30, the charging pile 20, the power grid information center 40, and the first device 50. The communication connection can include one or more types of connection media, including a wired link (for example, an optical fiber), a wireless link, or a combination of a wired link and a wireless link. For example, the connection medium can be a wireless link that indirectly connects through wireless communication, such as ultra-wideband (UWB) technology, long term evolution (LTE) communication technology, 5th generation mobile networks or 5th generation wireless systems, 5th-Generation (5G or 5G technology), global system for mobile communications (GSM), general packet radio service (GPRS), or universal mobile telecommunications system (UMTS).

[0116] As a possible implementation, the server 10 can assign a discharging task to the vehicle 30, and the vehicle 30 discharges electricity to the charging pile 20 through the first power supply connection interface 301 according to the discharging task, and the charging pile 20 receives the electricity transmitted by the vehicle 30 through the second power supply connection interface 201, thereby improving the management and control capability of the V2G charging pile and the new energy vehicle discharging work, and improving the measurement accuracy of the discharging amount in the V2G discharging process.

[0117] Further, the server 10 can also obtain discharging data of the vehicle 30 when performing the discharging task and charging pile data of the charging pile 20, and monitor the execution state of the discharging task according to the discharging data and the charging pile data, thereby improving the management and control capability of the V2G charging pile and the new energy vehicle discharging work. For example, when the execution state of the discharging task is abnormal, the server timely informs the discharging vehicle to exit the discharging task, reduces the loss of the discharging vehicle owner, and avoids the discharging vehicle owner reducing the enthusiasm of discharging to the power grid due to the loss of income. For another example, when the number of discharging vehicles whose execution state of the discharging task is abnormal reaches a quantity threshold when discharging to the charging pile, the server informs the management personnel of the discharging service that the charging pile may be malfunctioning and needs to be maintained in time, thereby minimizing the probability of the discharging vehicle owner encountering discharging failure.

[0134] Optionally, the first connection information is used to indicate that the discharge vehicle is electrically connected to the charging pile.

[0135] Optionally, the discharge control device and the discharge vehicle can establish a communication connection, and the discharge control device and the charging pile can establish a communication connection. For example, the discharge control device can obtain the first connection information from the discharge vehicle. For another example, the discharge control device can obtain the first connection information from the charging pile.

[0136] Correspondingly, when the discharge vehicle is successfully electrically connected to the charging pile, the discharge vehicle can send the first connection information to the discharge control device to indicate that the discharge vehicle is electrically connected to the charging pile.

[0137] In one possible implementation, the discharge vehicle and the charging pile can be preconfigured with a software port applicable to the present application, and the discharge control device can obtain the first connection information from the discharge vehicle through the software port configured by the discharge vehicle. For another example, the discharge control device can obtain the first connection information from the charging pile through the software port configured by the charging pile.

[0138] Correspondingly, when the discharging vehicle is successfully connected with the charging pile, the discharging vehicle can send first connection information to the discharging control device through a configured software port, and the first connection information indicates that the discharging vehicle is connected with the charging pile.

[0139] The discharging task is used to instruct the discharging vehicle to discharge to the charging pile.

[0140] Exemplarily, the discharging control device obtains the first connection information, the first connection information indicates that the discharging vehicle A is connected with the charging pile B, and the discharging control device allocates a discharging task to the discharging vehicle A, the discharging task is "the discharging vehicle A discharges to the charging pile B, and the discharging amount is H".

[0141] Correspondingly, the discharging vehicle receives the discharging task and controls the discharging vehicle to execute the discharging task. Exemplarily, the discharging vehicle A receives the discharging task and controls the discharging vehicle A to discharge to the charging pile B, and the discharging amount is H.

[0142] In a possible implementation, the discharging vehicle and the charging pile are preconfigured with a software port applicable to the present application, and the discharging control device can allocate a discharging task to the discharging vehicle through the software port configured by the discharging vehicle. Correspondingly, the discharging vehicle receives the discharging task through the software port configured by the discharging vehicle.

[0143] Optionally, a user of the discharging vehicle can select whether to execute the discharging task, and if the user of the discharging vehicle selects not to execute the discharging task, the discharging vehicle can be controlled to exit the electrical connection with the charging pile.

[0144] In addition, the discharging control device can allocate the discharging task to the discharging vehicle based on the following manners.

[0145] As a possible implementation, when the discharging control device detects that the current time is in a peak shaving time period, or the discharging control device receives a discharging instruction, the discharging task is allocated to the discharging vehicle, and the charging pile is instructed to start the charging function and the V2G discharging function. Optionally, the discharging instruction can come from a power grid information center or from a first device. The first device is a device used by an operator who sends discharging benefits to a user of the discharging vehicle.

[0146] Optionally, when the discharging control device detects that the current time is not in a peak shaving time period or does not receive a discharging instruction, the discharging control device instructs the charging pile to start the charging function.

[0147] Further, the discharging control device can acquire charging data of the vehicle charging through the charging pile and electric pile data of the charging pile, and monitor a state of a charging service according to the charging data and the electric pile data. The charging service is used to indicate that the charging pile charges the vehicle. For example, when the state of the charging service is abnormal, the discharging control device determines a reason for the abnormality and sends the reason for the abnormality to the vehicle and / or the charging pile.

[0148] For another example, when the discharging control device detects that the current time is in a peak load shifting time period or the discharging control device receives a discharging instruction, the discharging control device instructs the charging pile to start the V2G discharging function and the charging function. If the user of the discharging vehicle selects discharging, the discharging control device assigns a discharging task to the discharging vehicle, so that the discharging vehicle performs a discharging operation on the power grid through the charging pile to provide energy to the power grid. If the user of the discharging vehicle selects charging, the discharging vehicle performs a charging operation on the discharging vehicle through the charging pile.

[0149] As a possible implementation, when it is determined that the discharging qualification of the discharging vehicle is passed, the discharging control device assigns a discharging task to the discharging vehicle. Alternatively, when it is determined that the discharging qualification of the discharging vehicle is not passed, the discharging control device instructs that the discharging vehicle may have a fault and needs to be repaired. For example, when it is determined that the discharging qualification of the discharging vehicle is not passed, the discharging control device sends a message to the discharging vehicle that “discharging is not allowed, the vehicle may have a fault and needs to be repaired in an institution”. In this way, when the discharging qualification is passed, the discharging task is assigned to the discharging vehicle, so as to reduce the frequent impact on the power grid caused by the vehicles that do not meet the conditions and randomly join and / or exit the discharging task.

[0150] A possible example of determining whether the discharging qualification of the discharging vehicle is passed is introduced below.

[0151] In a possible example, the discharging control device performs a short-time discharging test on the discharging vehicle through the charging pile, and acquires first test data of the discharging vehicle and second test data of the charging pile. When a test error between the first test data and the second test data is less than a third error threshold, it is determined that the discharging qualification of the discharging vehicle is passed. The discharging control device can perform the short-time discharging test on the discharging vehicle according to a discharging test curve task corresponding to the vehicle model of the discharging vehicle.

[0152] In a possible implementation, the discharging vehicle and the charging pile are preconfigured with a software port applicable to the present application. The discharging vehicle can send the first test data of the discharging vehicle to the discharging control device through the software port configured by the discharging vehicle, and the charging pile can send the second test data of the charging pile to the discharging control device through the software port configured by the charging pile.

[0153] Exemplarily, when the test error between the first test data and the second test data is less than the third error threshold, it is determined that the discharging qualification of the discharging vehicle passes the test, and when the test error between the first test data and the second test data is greater than or equal to the third error threshold, the discharging control device performs the short-time discharging test on the discharging vehicle again through the charging pile until the test error of the discharging vehicle in the short-time discharging test is less than the third error threshold, or the number of tests reaches a test threshold. When the number of tests reaches the test threshold, the discharging control device stops performing the short-time discharging test on the discharging vehicle A again. The number of tests is the number of times of performing the short-time discharging test on the discharging vehicle through the charging pile. The third error threshold (for example, Δp3) is a parameter set by an operator who sends the discharging benefit to the user of the discharging vehicle, and the third error threshold is related to factors such as the vehicle model of the vehicle and the model of the charging pile. The test threshold (for example, k) is a parameter set by an operator who sends the discharging benefit to the user of the discharging vehicle, and the test threshold is related to factors such as the vehicle model of the vehicle and the model of the charging pile.

[0154] Exemplarily, taking the test threshold of 3 times as an example, if the discharging control device determines that the first test error of the discharging vehicle A is greater than or equal to the third error threshold in the process of performing the first short-time discharging test on the discharging vehicle A through the charging pile B, the discharging control device performs the second short-time discharging test on the discharging vehicle A through the charging pile B. If the discharging control device determines that the second test error of the discharging vehicle A is less than the third error threshold in the process of performing the second short-time discharging test, the discharging control device determines that the discharging qualification of the discharging vehicle A passes the test. If the discharging control device determines that the second test error of the discharging vehicle A is still greater than or equal to the third error threshold in the process of performing the second short-time discharging test, the discharging control device performs the third short-time discharging test on the discharging vehicle A through the charging pile B. If the discharging control device determines that the third test error of the discharging vehicle A is still greater than or equal to the third error threshold in the process of performing the third short-time discharging test, since the number of tests is 3 which has reached the test threshold, the discharging control device cannot perform the short-time discharging test on the discharging vehicle A again, and it is determined that the discharging qualification of the discharging vehicle A does not pass the test. If the discharging control device determines that the test error of the discharging vehicle A in the process of performing the first, second, or third short-time discharging test is less than the third error threshold, the discharging control device determines that the discharging qualification of the discharging vehicle A passes the test.

[0155] Optionally, if the discharge control device determines that the discharge qualification of the discharging vehicle fails to pass the detection, the discharge control device can instruct the discharging vehicle to replace the charging pile. When the number of times of replacing the charging pile by the discharging vehicle reaches a replacement number threshold, the discharge control device instructs the discharging vehicle to have a fault and needs to be repaired. The replacement number threshold (for example, K) is a parameter set by an operator sending a discharge benefit to a user of the discharging vehicle, and the replacement number threshold is related to factors such as the vehicle model of the vehicle and the model of the charging pile.

[0156] Illustratively, when the number of times of replacing the charging pile by the discharging vehicle reaches the replacement number threshold, the discharge control device sends a message to the discharging vehicle that "discharge cannot be performed, the vehicle may have a fault and needs to go to an agency for repair".

[0157] As a possible implementation, when the discharge control device detects that the current time is in a peak shaving time period, or the discharge control device receives a discharge instruction, and determines that the discharge qualification of the discharging vehicle passes the detection, the discharge control device assigns a discharge task to the discharging vehicle.

[0158] Since the discharging vehicle needs to have a discharge capability to participate in discharge, the discharge capability of the vehicle can be affected by low power or vehicle hardware failure, so the discharging vehicle also needs to meet a preset condition.

[0159] As a possible implementation, the preset condition includes but is not limited to that the vehicle hardware of the discharging vehicle has no fault, the remaining power of the discharging vehicle is higher than a power threshold, and a handshake protocol is successful. The power threshold is a parameter set by an operator sending a discharge benefit to a user of the discharging vehicle, and the power threshold is related to factors such as the vehicle model of the vehicle and the model of the charging pile. For example, the power threshold is 60% or 65%. Optionally, the discharging vehicle and the charging pile can be preconfigured with a handshake protocol applicable to the present application. When the discharging vehicle and the charging pile are successfully connected, the discharging vehicle and the charging pile send indication information to the discharge control device to indicate that the handshake protocol is successful.

[0160] As a possible implementation, when the discharging vehicle does not meet the preset condition, the discharge control device instructs the discharging vehicle to have a fault and needs to be repaired. Illustratively, when the discharging vehicle does not meet the preset condition, the discharge control device sends a message to the discharging vehicle that "discharge cannot be performed, the vehicle may have a fault and needs to go to an agency for repair".

[0161] As a possible implementation, when the discharging vehicle meets the preset condition, the discharge control device determines whether the discharge qualification of the discharging vehicle passes the detection.

[0162] Further, the discharge control device obtains discharge data when the discharging vehicle performs the discharge task and pile data of the charging pile.

[0163] Correspondingly, when performing the discharging task, the discharging vehicle can send the discharging data of the discharging vehicle performing the discharging task to the discharging control device. The charging pile can send the pile data of the charging pile to the discharging control device. For example, the charging pile B can send the charging data of the charging pile B when the discharging vehicle A discharges to the charging pile B to the discharging control device.

[0164] In a possible implementation, the discharging vehicle and the charging pile are preconfigured with a software port applicable to the application. The discharging vehicle can send the discharging data of the discharging vehicle performing the discharging task to the discharging control device through the software port configured by the discharging vehicle. The charging pile can send the pile data of the charging pile to the discharging control device through the software port configured by the charging pile.

[0165] As a possible implementation, the discharging control device obtains the discharging data of the discharging vehicle performing the discharging task and the pile data of the charging pile once every first time length. The first time length is a pre-set parameter, for example, 5 seconds, 8 seconds, etc.

[0166] As a possible implementation, the discharging control device obtains the discharging data of the discharging vehicle performing the discharging task and the pile data of the charging pile in real time.

[0167] Further, the discharging control device monitors the execution state of the discharging task according to the discharging data and the pile data.

[0168] As a possible implementation, when the execution state of the discharging task is abnormal, the discharging control device instructs the discharging vehicle to exit the discharging task. Alternatively, when the number of times that the execution state of the discharging task is abnormal reaches a discharging abnormality number threshold, the discharging control device instructs the discharging vehicle to exit the discharging task. The discharging abnormality number threshold is a parameter set by an operator sending the discharging benefit to the user of the discharging vehicle. The discharging abnormality number threshold is related to factors such as the vehicle model of the discharging vehicle and the model of the charging pile.

[0169] Illustratively, when the execution state of the discharging task is abnormal, the discharging control device sends “discharging abnormality, it is suggested to exit the discharging task in time” to the discharging vehicle. In this way, the discharging vehicle is notified to exit the discharging task in time, the loss of the owner of the discharging vehicle is reduced, and the enthusiasm of the owner of the discharging vehicle for discharging to the power grid is avoided to be reduced due to the loss of the benefit.

[0170] As a possible implementation, when the execution state of the discharging task is abnormal, the discharging control device sends first information to the first device, the first information being used to indicate that the discharging function is abnormally fluctuated. Optionally, when the number of times that the execution state of the discharging task is abnormal reaches a discharging abnormality threshold, the discharging control device sends the first information to the first device. For example, the manager of the discharging service is informed that the discharging function is abnormally fluctuated, and the abnormal fluctuation needs to be eliminated in time to ensure the normal execution of the discharging task and to reduce the probability of discharging failure encountered by the discharging vehicle owner as much as possible.

[0171] Further, the discharging control device receives second information from the first device, and when the second information indicates that the abnormal fluctuation is not eliminated, the discharging control device sends third information to the discharging vehicle. The second information is used to indicate whether the abnormal fluctuation is eliminated, and the third information is used to indicate that the discharging vehicle exits the discharging task and / or the third information is used to indicate that the discharging vehicle is faulty. Optionally, when the second information indicates that the abnormal fluctuation is eliminated, the discharging control device instructs the discharging vehicle to continue the discharging task.

[0172] For example, when the execution state of the discharging task is abnormal, the discharging control device sends “the discharging function between the charging pile B and the discharging vehicle A is abnormally fluctuated, and the fluctuation needs to be eliminated” to the first device. The operator of the discharging benefit of the user of the discharging vehicle learns through the first device that the abnormal fluctuation of the discharging function between the charging pile B and the discharging vehicle A needs to be eliminated, eliminates the abnormal fluctuation, and sends second information to the discharging control device through the first device. The discharging control device receives the second information, and when the second information indicates that the abnormal fluctuation is not eliminated, the discharging control device sends “discharging abnormality, it is suggested to exit the discharging task in time” and / or “discharging abnormality, the vehicle may be faulty and needs to be repaired in an institution” to the discharging vehicle A. For example, when the abnormal fluctuation is not eliminated, the discharging control device informs the discharging vehicle to exit the discharging task in time, reduces the loss of the discharging vehicle owner, and avoids the discharging vehicle owner reducing the enthusiasm of discharging to the power grid due to the loss of benefits. For another example, when the abnormal fluctuation is not eliminated, the discharging vehicle owner is informed in time that the discharging vehicle may be faulty, and the discharging vehicle needs to be maintained in time to reduce the probability of discharging failure encountered by the discharging vehicle owner as much as possible.

[0173] Exemplarily, the abnormality of the execution state of the discharging task includes one or more of the following: the deviation between the discharging data and the charging pile data is greater than or equal to a first error threshold value, the number of times that the deviation between the discharging data and the charging pile data is greater than or equal to a second error threshold value reaches an abnormal number threshold value. The first error threshold value (for example, Δp1) and the second error threshold value (for example, Δp2) can be the same or different. The first error threshold value and the second error threshold value are parameters set by the operator who sends the discharging benefit to the user of the discharging vehicle, and are related to factors such as the vehicle model of the vehicle and the model of the charging pile.

[0174] Exemplarily, when the deviation between the discharging data and the charging pile data is greater than or equal to the first error threshold value, the discharging control device determines that the execution state of the discharging task is abnormal. For example, the first error threshold value is set to be large, and when the deviation between the discharging data and the charging pile data is greater than or equal to the first error threshold value, the discharging control device determines that the deviation between the discharging data and the charging pile data is too large, and the possibility that the execution state of the discharging task is abnormal is large, thereby timely informing the owner of the discharging vehicle to reduce the loss of the owner.

[0175] Exemplarily, when the number of times that the deviation between the discharging data and the charging pile data is greater than or equal to the second error threshold value reaches the abnormal number threshold value, the discharging control device determines that the execution state of the discharging task is abnormal. For example, the deviation between the discharging data and the charging pile data is large, and the number of times that the deviation is large is large and frequent, and the discharging control device determines that the possibility that the execution state of the discharging task is abnormal is large, which can improve the accuracy of monitoring the execution state of the discharging task, thereby timely informing the owner of the discharging vehicle to reduce the loss of the owner. Alternatively, when the number of times that the deviation between the discharging data and the charging pile data is greater than or equal to the second error threshold value does not reach the abnormal number threshold value, the discharging control device determines that the execution state of the discharging task is normal fluctuation.

[0176] As a possible implementation, when the execution state of the discharging task is not abnormal, the discharging control device performs metering and charging according to the charging pile data until the discharging task ends. Exemplarily, the discharging control device performs metering and charging according to the actual charging amount of the charging pile to determine the discharging benefit, and when the discharging task ends, the discharging benefit is transferred to the account of the user of the discharging vehicle. Exemplarily, the account information of the user of the discharging vehicle is input by the user in advance, and the discharging control device obtains the account information of the user and stores it in the discharging control device.

[0177] As a possible implementation, the discharge control device can update the number of abnormal discharge vehicles. The abnormal discharge vehicle is a discharge vehicle whose discharge task execution state is abnormal when discharging to the charging pile. For example, if there are 5 discharge vehicles whose discharge task execution state is abnormal when discharging to the charging pile B, then these 5 discharge vehicles are all abnormal discharge vehicles.

[0178] Further, when the number of abnormal discharge vehicles reaches a number threshold, the fourth information is sent to the charging pile and / or the first device. The number threshold is a parameter set by the operator who sends the discharge benefit to the user of the discharge vehicle, and the number threshold is related to factors such as the model of the charging pile. The fourth information is used to indicate that the charging pile has a fault. For example, when the number of abnormal discharge vehicles reaches the number threshold, the first device is sent "discharge abnormality, charging pile B may have a fault, and needs to be repaired". In this way, the number of discharge tasks that have exited abnormally is updated in a timely manner, and when the number of abnormal discharge vehicles reaches the number threshold, the management personnel of the discharge service is notified that the charging pile may have a fault and needs to be maintained in a timely manner, thereby minimizing the probability of discharge failure encountered by the owner of the discharge vehicle.

[0179] As another possible implementation, the discharge control device can update the abnormal discharge task indication. The abnormal discharge task indication is used to indicate the number of discharge tasks whose execution state is abnormal when discharging to the charging pile.

[0180] Further, when the number of discharge tasks whose execution state is abnormal reaches a number threshold, the second information is sent to the first device.

[0181] In one possible implementation, when the discharge control device detects that the peak shaving period ends, or when the discharge control device receives a stop discharge indication, the discharge control device instructs the charging pile to close the V2G discharge function and only open the charging function, and at the same time instructs the discharge vehicle to exit the discharge task. Optionally, the stop discharge indication can come from the power grid information center or from the first device.

[0182] As a possible implementation, the discharge control device can also monitor and debug the discharge quality of the vehicle type of the discharge vehicle, the discharge task completion rate of the user of the discharge vehicle, and fault data according to the discharge data and the pile data, so as to improve the supervision ability of the discharge function.

[0183] In the embodiment shown in FIG. 3, the discharge control device can assign discharge tasks to discharge vehicles, and the discharge vehicles discharge to the charging pile based on the discharge tasks, which can improve the control ability of the V2G charging pile and the discharge work of new energy vehicles, and also improve the measurement accuracy of the discharge amount in the V2G discharge process.

[0184] Further, the discharge control device can also monitor the execution state of the discharge task of the discharge vehicle according to the discharge data of the discharge vehicle and the electric pile data of the charging pile, so as to improve the management and control capability of the V2G charging pile and the discharge work of the new energy vehicle. For example, when the execution state of the discharge task appears abnormal, the discharge control device timely informs the discharge vehicle to exit the discharge task, reduces the loss of the owner of the discharge vehicle, and avoids the owner of the discharge vehicle from reducing the enthusiasm of discharging to the power grid due to the loss of income. For another example, when the number of discharge vehicles whose execution state of the discharge task appears abnormal reaches a quantity threshold when discharging to the charging pile, the discharge control device informs the manager of the discharge service that the charging pile may be malfunctioning and needs to be maintained in time, so as to minimize the probability of the owner of the discharge vehicle encountering discharge failure.

[0185] The above describes the method of the embodiments of the application in detail, and the device of the embodiments of the application is provided below.

The third information may be used to instruct the discharge vehicle to exit the discharge task and / or to indicate that the discharge vehicle has malfunctioned.

[0192] In one possible implementation, an abnormality in the execution status of the discharge task includes one or more of the following: the deviation between the discharge data and the charging pile data is greater than or equal to a first error threshold, and the number of times the deviation between the discharge data and the charging pile data is greater than or equal to a second error threshold reaches an abnormal number threshold.

[0193] In one possible implementation, the processor 401 is also used to update the number of vehicles with abnormal discharge, which are vehicles whose discharge task execution status is abnormal when discharging to the charging pile.

The fourth message is used to indicate that the charging pile has malfunctioned, and the abnormally discharging vehicles are those whose discharge task execution status has become abnormal when discharging to the charging pile.

[0196] In one possible implementation, the processor 401 is also configured to assign a discharge task to the discharge vehicle if it is determined that the discharge vehicle has passed the discharge qualification test.

[0197] In one possible implementation, the processor 401 is further configured to perform a short-term discharge test on the discharge vehicle via a charging pile, the acquirer 402 is further configured to acquire first test data of the discharge vehicle and second test data of the charging pile, and the processor 401 is further configured to determine that the discharge qualification of the discharge vehicle is passed if the test error between the first test data and the second test data is less than a third error threshold.

[0198] In one possible implementation, the processor 401 is further configured to:

[0199] If the first test data and the second test data are greater than the third error threshold, the vehicle will be tested again through the charging pile for a short time until the test error of the vehicle during the short time discharge test is less than the third error threshold or the number of tests reaches the test threshold. The number of tests is the number of times the vehicle is tested for a short time through the charging pile.

[0200] In a case where the test error of the discharging vehicle in the short-time discharging test process is less than a third error threshold, it is determined that the discharging qualification of the discharging vehicle is passed.
