Description

Technical Field

[0001] This application belongs to the technical field of management systems, and more particularly, relates to a charging pile power distribution method and device. Background Art

[0003] With the increasing popularity of electric vehicles, the number of charging piles is constantly increasing. When the grid load is too high, simultaneous charging of a large number of charging piles can easily affect the grid load, which may cause problems such as grid failures or a decline in power quality. Summary of the Invention

Obviously, the following drawings are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

Detailed Embodiments

[0012] In the following description, specific details such as specific system structures and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0013] To make the objectives, technical solutions, and advantages of the present application clearer, the following will be described through specific embodiments with reference to the drawings.

[0014] Please refer to Figure 1 , Figure 1 It is a schematic flowchart of a charging pile power distribution method provided by an embodiment of the present application, and the method includes: S101: Determine the priority of each charging pile based on the charging pile information and the corresponding charging vehicle information.

[0015] In this embodiment, the charging pile information may include the type of the charging pile (such as fast charging pile, slow charging pile), power size, etc. For charging piles with different types and powers, their importance is different. For example, a fast charging pile can replenish the vehicle's power in a short time and reduce the queuing time, so its priority is relatively high; a slow charging pile has a slower charging speed, and the corresponding vehicle usually does not need to be fully charged immediately and can complete charging within a longer time period, so its priority is relatively low.

[0016] The charging vehicle information may include information such as vehicle type and remaining vehicle power. Among them, the vehicle type information can be identified according to the communication protocol between the vehicle and the charging pile. When different types of vehicles communicate with the charging pile, they will follow different communication protocols or contain specific identification information, and the vehicle type can be determined by parsing the communication data between the vehicle and the charging pile; the remaining vehicle power can be obtained through the data of the vehicle's battery management system.

[0017] Considering some special types of vehicles, such as emergency rescue vehicles like ambulances and fire trucks, in order to ensure their execution of emergency tasks, the highest priority should be given to ensure that they can charge quickly. In addition, to avoid the vehicle being unable to drive due to exhausted power, causing traffic congestion or other inconveniences, vehicles with relatively low remaining power should usually be charged first. For example, when the remaining vehicle power is less than 20%, the charging priority of the vehicle can be appropriately increased.

[0018] Therefore, in this embodiment, the priority of each charging pile is determined based on the charging pile information and the corresponding charging vehicle information, and the power distribution of the charging pile in the subsequent steps is based on the priority, which can make the power distribution of the charging pile more in line with the actual needs.

[0019] S102: In response to the grid load in the area where the charging pile is located being greater than the first threshold, select the first target charging pile based on the priority of each charging pile, and reduce the charging power of the first target charging pile by the first step size.

[0020] In this embodiment, the grid load in the area where the charging pile is located can be obtained by reading the data of the power monitoring system (SCADA). This system can monitor the operating status of the power system in real time, including parameters such as the voltage, current, and power of the grid. When the grid load in the area where the charging pile is located is greater than the first threshold, it indicates that the grid load is large. At this time, according to the priority of each charging pile, a charging pile with a lower priority can be selected as the first target charging pile, and the charging power of the first target charging pile is reduced by the first step size to reduce the grid load. Among them, both the first threshold and the first step size are preset constants, and those skilled in the art can flexibly design the specific values of the second threshold and the second step size according to actual needs.

[0021] Specifically, the selection of the first target charging pile based on the priority of each charging pile can be described in detail as follows: Select the charging pile with the lowest priority from multiple first charging piles, and determine the charging pile with the lowest priority as the first target charging pile; the first charging pile is a charging pile that has not undergone power reduction processing.

[0022] In this embodiment, it is possible to detect whether the grid load in the area where the charging pile is located is greater than the first threshold in each control cycle of the charging pile. If the grid load in the area where the charging pile is located is greater than the first threshold, then determine the charging pile with the lowest priority as the first target charging pile, reduce the charging power of the first target charging pile, and mark the charging pile as the second charging pile (indicating that the charging pile has undergone power adjustment and the charging power has been reduced). In this way, in the next control cycle, the second charging pile will no longer be power-adjusted, but the charging pile with the lowest priority will be selected as the first target charging pile from other charging piles that have not undergone power reduction processing (i.e., the first charging piles), thereby avoiding reducing the power of the same charging pile multiple times and causing the power of the charging pile to be too low.

[0023] In the above process, if there are multiple first charging piles with the lowest priority (the same priority), one charging pile can be randomly selected from the multiple first charging piles as the first target charging pile.

[0024] It can be concluded from the above that in order to avoid the impact of a large number of charging piles charging simultaneously on the grid load, in this embodiment, when the grid load is high, the charging power of the charging pile is timely reduced to avoid excessive impact on the grid and ensure the stable operation of the grid. At the same time, considering that the battery capacities, remaining battery powers, and charging power requirements of different electric vehicles are different, therefore, the priorities of each charging pile are determined based on the charging pile information and the corresponding charging vehicle information. When the grid load in the area where the charging pile is located exceeds the preset first threshold, the first target charging pile whose power needs to be adjusted is selected according to the priorities of each charging pile, and the power of the charging pile with a lower priority is preferentially reduced, which can not only relieve the grid pressure but also try to meet the charging needs of users and avoid affecting the user experience.

[0025] In an embodiment of the present application, the charging pile information includes the type of the charging pile, and the charging vehicle information includes the vehicle type and the remaining battery power of the vehicle. Determining the priorities of each charging pile based on the charging pile information and the corresponding charging vehicle information includes: Determining the first sorting number of each charging pile based on the vehicle type corresponding to the charging pile; Determining the second sorting number of each charging pile based on the remaining battery power of the vehicle corresponding to the charging pile; Determining the third sorting number of each charging pile based on the type of the charging pile; Determine the priority of each charging pile based on the first sorting number, the second sorting number, and the third sorting number.

[0026] In this embodiment, the priority of each charging pile can be sorted at three levels according to the vehicle type, the remaining power of the vehicle, and the type of the charging pile.

[0027] In the first-level sorting, the first sorting number of each charging pile can be determined according to the vehicle type. Specifically, when the vehicle type belongs to a specified vehicle type (such as an ambulance, a fire truck, etc.), the corresponding first sorting number is 1, and when the vehicle type belongs to other vehicle types, the corresponding first sorting number is 2.

[0028] In the second-level sorting, the second sorting number of each charging pile can be determined according to the remaining power of the vehicle. Specifically, when the remaining power of the vehicle is less than the set power (such as 20%), the corresponding second sorting number is 1, otherwise, the corresponding second sorting number is 2.

[0029] In the third-level sorting, the third sorting number of each charging pile can be determined according to the type of the charging pile. Specifically, when the type of the charging pile is a fast charging pile, the corresponding third sorting number is 1, otherwise, the corresponding third sorting number is 2.

[0030] On the basis of obtaining the first sorting number, the second sorting number, and the third sorting number, the first sorting number, the second sorting number, and the third sorting number are concatenated to obtain the priority of each charging pile. For example, a certain charging pile is charging a fire truck, the remaining power of the vehicle is 10%, and this charging pile is a fast charging pile, then the corresponding priority of this charging pile is 111.

[0031] When comparing the priorities of each charging pile, the charging pile with a smaller priority number has a higher corresponding priority. For example, the charging pile with a priority number of 111 has a higher priority than the charging pile with a priority number of 122.

[0032] It can be concluded from the above that this embodiment comprehensively considers factors such as vehicle type, remaining power of the vehicle, and type of the charging pile to determine the priority of each charging pile, which can keep the vehicles in greater need of charging at a higher charging power, thereby reducing the charging waiting time of these vehicles, improving the overall charging efficiency, and enhancing the charging experience and service quality of users.

[0033] In an embodiment of the present application, the charging pile power distribution method further includes: In response to the grid load in the area where the charging pile is located being less than the second threshold, select a second target charging pile based on the priority of each charging pile, and increase the charging power of the second target charging pile by a second step length.

[0034] In this embodiment, when the grid load in the area where the charging pile is located is less than the second threshold, it indicates that the grid in the area where the charging pile is located has a certain remaining power supply capacity, which can provide more power support for the charging pile to meet the charging needs of more vehicles. At this time, the charging pile with a higher priority can be preferentially selected as the second target charging pile, and the charging power of the first target charging pile can be increased by the second step length, which can ensure that more important or more urgently needed vehicles can obtain a higher charging power first. Among them, both the second threshold and the second step length are preset constants, and those skilled in the art can flexibly design the specific values of the second threshold and the second step length according to actual needs.

[0035] In an embodiment of the present application, the charging pile power distribution method further includes: Determining a first adjustment parameter based on the operating state of the second target charging pile; Determining a second adjustment parameter based on the charging stage of the vehicle corresponding to the second target charging pile; Determining the smaller value of the first adjustment parameter and the second adjustment parameter as the third adjustment parameter; Adjusting the rated power of the second target charging pile based on the third adjustment parameter to obtain a power limit value; If the charging power of the second target charging pile is greater than the power limit value, determining the charging power of the second target charging pile as the power limit value.

[0036] In this embodiment, considering that the charging power of the second target charging pile is affected by its own operating state and the charging stage of the vehicle, therefore, the charging power of the second target charging pile cannot be increased without limit.

[0037] Among them, the operating state of the second target charging pile includes its own hardware health condition. If a certain component of the second target charging pile is overheated or a certain power module fails and needs to be withdrawn, its charging power needs to be reduced. Specifically, when some faults that affect power output occur in the second target charging pile, a smaller first adjustment parameter can be set, and the rated power of the second target charging pile can be adjusted based on the first adjustment parameter to obtain a power limit value to limit the charging power, ensure that the charging pile charges the vehicle on the premise of its own safe operation, and prevent safety accidents caused by faults.

[0038] The charging stage of a vehicle is usually divided into multiple stages such as fast charging stage, slow charging stage, trickle charging stage, etc. Different charging stages have different requirements for charging power. Generally speaking, at the initial stage of the fast charging stage, the vehicle can accept a relatively high charging power. However, as the battery power gradually increases, in order to protect the battery life and safety, the charging power needs to be gradually reduced. Therefore, the second adjustment parameter can be determined according to the charging stage of the vehicle, and the rated power of the second target charging pile is adjusted based on the second adjustment parameter to obtain a power limit value, so as to limit the charging power and avoid affecting the battery life due to too high charging power.

[0039] On the basis of obtaining the first adjustment parameter and the second adjustment parameter, the first adjustment parameter and the second adjustment parameter can be weighted and summed to obtain a third adjustment parameter. The third adjustment parameter can comprehensively reflect the influence of the operating state of the charging pile and the charging stage of the vehicle on the charging power. The power limit value obtained by adjusting the rated power of the second target charging pile based on the third adjustment parameter can not only meet the basic charging needs of the vehicle, but also ensure the safety and stability of the charging pile and the vehicle.

[0040] It can be concluded from the above that this embodiment comprehensively considers the factors of the charging pile and the vehicle to accurately adjust the charging power, making the charging process more scientific and reasonable.

[0041] In an embodiment of the present application, determining the first adjustment parameter based on the operating state of the second target charging pile includes: If the operating state of the second target charging pile shows that the second target charging pile has a specified fault type, search for a mapping relationship based on the specified fault type to obtain a fourth adjustment parameter corresponding to the specified fault type; Determine the fourth adjustment parameter as the first adjustment parameter.

[0042] In this embodiment, the specified fault type may include charging module failure, battery management system (BMS) failure, grid voltage fluctuation, communication failure, cooling system failure, etc.

[0043] Among them, the charging module is a key component that converts grid electric energy into DC electric energy suitable for electric vehicle charging. When the charging module fails, such as partial power unit damage, overheating caused by poor heat dissipation, etc., its output power may be unstable or unable to reach the rated power. In order to avoid further damage to the charging module or causing safety problems, it is necessary to reduce the charging power to reduce the working burden of the charging module and make it continue to work within an acceptable range.

[0044] The Battery Management System (BMS) is responsible for monitoring and managing the state of the electric vehicle battery, including parameters such as voltage, current, and temperature. If the BMS fails, it may lead to inaccurate monitoring of the battery state and inability to correctly control the charging process. Therefore, when the BMS fails, it is usually necessary to reduce the charging power to reduce the risks during the charging process while waiting for the BMS to be repaired or replaced.

[0045] Both too high and too low grid voltages will affect the input voltage of the charging pile. If the input voltage exceeds the normal operating range of the charging pile, it may cause damage or abnormal operation of the electronic components inside the charging pile. To protect the charging pile and the battery of the electric vehicle, when the grid voltage fluctuates, measures to reduce the charging power are usually taken to enable the charging pile to adapt to the change of the grid voltage while ensuring the continuation of the charging process as much as possible.

[0046] When a communication failure occurs, it may lead to unsmooth information interaction during the charging process and inability to accurately control the charging power and time. For example, if the charging pile cannot communicate normally with the electric vehicle BMS, it cannot obtain the real-time state information of the battery. To avoid abnormalities during the charging process, the charging power will be reduced to wait for the communication to return to normal and ensure the safety and accuracy of the charging process.

[0047] Heat is generated during the charging process, and a cooling system is required to maintain the normal operating temperature of the charging pile and the battery. If the cooling system fails, such as a fan failure or coolant leakage, it will cause the temperature of the charging equipment or the battery to rise. Excessive temperature will affect the charging efficiency, accelerate equipment aging, and even cause safety accidents. Therefore, when the cooling system fails, to prevent the temperature from rising further, it is necessary to reduce the charging power and reduce the heat generation to ensure that the charging equipment and the battery operate within a safe temperature range.

[0048] In this embodiment, a fourth adjustment parameter can be preset in advance, and a mapping relationship between a specified fault type and the fourth adjustment parameter can be constructed based on historical data. The fourth adjustment parameter is used to characterize the influence degree of the specified fault type on the charging power. The fourth adjustment parameter can be used as the first adjustment parameter, and the power limit value can be obtained by multiplying the fourth adjustment parameter by the rated power of the second target charging pile. The smaller the fourth adjustment parameter, the smaller the power limit value.

[0049] From the above, it can be concluded that in this embodiment, by constructing a mapping relationship between a specified fault type and the fourth adjustment parameter, when the charging pile has a fault of the specified fault type, the power limit value of the charging pile can be automatically adjusted to avoid further damage to the equipment or affecting the charging safety.

[0050] In an embodiment of the present application, the charging pile power distribution method further includes: If multiple specified fault types are specified and the correlation degree of the multiple specified fault types is less than or equal to the first correlation degree, the smallest fourth adjustment parameter among the multiple fourth adjustment parameters corresponding to the multiple specified fault types is determined as the first adjustment parameter.

[0051] In this embodiment, the correlation degree between any two specified fault types can be realized by statistically calculating the conditional probability of the two specified fault types in historical data. Specifically, the correlation degree between the i-th fault type and the j-th fault type can be calculated by the formula where, represents the correlation degree between the i-th fault type and the j-th fault type, represents the probability that the j-th fault type occurs under the condition that the i-th fault type occurs; represents the probability that the i-th fault type occurs under the condition that the j-th fault type occurs.

[0052] In this embodiment, the correlation degree of multiple specified fault types being less than or equal to the first correlation degree means that for every two specified fault types among the multiple specified fault types, the correlation degree is less than or equal to the first correlation degree. Among them, the first correlation degree is a preset constant, and those skilled in the art can flexibly design the specific value of the first correlation degree according to actual needs.

[0053] When the correlation degree of multiple specified fault types is low, it indicates that each fault type is independent of each other. At this time, the smallest fourth adjustment parameter can be selected as the first adjustment parameter to avoid excessive reduction of the charging power due to the superposition of the fourth adjustment parameters of multiple faults. For example, when a module fault and a communication fault occur simultaneously in a charging pile, if the fourth adjustment parameters corresponding to the two faults are superimposed, the power may be significantly reduced. However, by using the smallest fourth adjustment parameter (the fourth adjustment parameter corresponding to the module fault) and only adjusting the charging power for the module fault, the requirements for charging power adjustment in the case of a communication fault can be met simultaneously.

[0054] In an embodiment of the present application, the charging pile power distribution method further includes: If multiple specified fault types are specified and the correlation degree of the multiple specified fault types is greater than the first correlation degree, the multiple fourth adjustment parameters corresponding to the multiple specified fault types are weighted and summed to obtain the first adjustment parameter.

[0055] In this embodiment, if among multiple fault types, there are at least two faults with a correlation degree greater than the first correlation degree, it indicates that there is a strong correlation between the faults and multiple faults affect each other. At this time, the weighted summation method can be used to calculate the first adjustment parameter to comprehensively consider the influence of each fault type on the charging power of the charging pile.

[0056] Specifically, the following first formula can be used to calculate the weight of each fault type:

[0057] Among them, represents the weight of the i-th fault type, and n represents the number of fault types.

[0058] In this embodiment, when multiple specified fault types occur simultaneously, the weights of each specified fault type are determined based on the correlation degree between the fault types. If a certain fault has a high correlation with other faults, its corresponding weight is high. Using the above method of weighted summation can more comprehensively consider the comprehensive influence of multiple related faults, which is beneficial to the precise adjustment of the charging power of the charging pile.
