Description

Technical Field

[0001] This application relates to the field of community power management, and particularly to a method, system, medium and product for allocating the charging power of electric vehicles in a community. Background Art

[0002] With the popularization of electric vehicles, people's charging demand for them is increasing day by day. In urban communities, residents generally own electric vehicles and private charging piles. However, due to the limited power resources in the community, the community power grid often faces huge challenges during peak electricity consumption periods. In this case, how to reasonably and effectively allocate power resources to meet the charging demand of residents for electric vehicles while ensuring the stable operation of the community power grid has become an urgent problem to be solved.

[0003] Currently, most communities adopt reservation-based charging, that is, during peak electricity consumption periods, residents can connect their electric vehicles to the charging piles in advance and reserve the charging time during off-peak electricity consumption periods to charge the electric vehicles.

[0004] However, this method limits the charging flexibility of users in case of sudden demand. For example, a user immediately needs to use the electric vehicle, but the electric vehicle has insufficient power and it is during the peak electricity consumption period at this time and cannot be charged in time, resulting in the user's charging demand not being met and causing inconvenience to the user. Summary of the Invention

[0005] This application provides a method, system, medium and product for allocating the charging power of electric vehicles in a community, which is used to reasonably and effectively allocate power resources to meet the electricity consumption demand of residents for charging electric vehicles while ensuring the stable operation of the community power grid.

[0006] In a first aspect, the present application provides a method for allocating the charging power of electric vehicles in a community, which is applied to a community power management system. The method includes: when an electric vehicle is connected to a target charging pile, obtaining the user's electricity consumption demand, which includes the planned charging amount and the planned charging duration, and the planned charging duration is during the peak period of community electricity consumption; determining the planned charging power according to the planned charging amount and the planned charging duration; if the planned charging power exceeds the peak standard allocation power of the target charging pile, obtaining the usage power of other charging piles; if there is other charging pile whose usage power is less than the peak standard allocation power, allocating the difference power of the other charging pile to the target charging pile to obtain the supplementary configured power of the target charging pile, where the difference power is used to represent the difference between the peak standard allocation power and the usage power; if the supplementary configured power of the target charging pile is greater than the planned charging power, charging the electric vehicle based on the planned charging power within the planned charging duration; if the supplementary configured power of the target charging pile is less than the planned charging power, charging the electric vehicle based on the supplementary configured power within the first charging duration; determining the remaining charging amount of the electric vehicle according to the first charging duration, the supplementary configured power and the planned charging amount; using the remaining charging amount as the planned charging amount and the second charging duration as the planned charging duration, and continuing to execute the steps after obtaining the user's electricity consumption demand when the electric vehicle is connected to the target charging pile until the remaining charging amount is 0, and the sum of the first charging duration and the second charging duration is the planned charging duration.

[0007] By adopting the above technical solution, during the peak period of community electricity consumption, if it is necessary to complete the planned charging amount within the planned charging duration, it may cause the planned charging power of the charging pile to exceed the current community load. Therefore, the community power management system can dynamically adjust the power allocation of other charging piles, allocate the difference power of other charging piles that are not fully utilized to the target charging pile with higher current electricity consumption demand, realize the optimal utilization of power resources, and effectively solve the contradiction between the charging demand of electric vehicles in the community and the power supply capacity of the power grid. At the same time, the method can also dynamically adjust the charging plan according to the actual charging situation to ensure that the electric vehicle can complete the charging of the electric vehicle within the user's planned charging duration, not only improving the charging efficiency, but also balancing the grid load and avoiding the power supply pressure during the peak electricity consumption period. In addition, the method can adapt to different electricity consumption demands and grid conditions, provide more convenient and reliable charging services for users, and at the same time provide an efficient solution for community power management.

[0008] In connection with some embodiments of the first aspect, in some embodiments, before the step of obtaining the usage power of other charging piles if the planned charging power exceeds the peak standard allocation power of the target charging pile, the method further includes: obtaining the historical power consumption data of users in the community; based on the historical power consumption data, determining the peak power consumption period and the off-peak power consumption period of the community; determining the peak standard allocation power of the target charging pile during the peak power consumption period of the community and the off-peak standard allocation power of the target charging pile during the off-peak power consumption period of the community, where the peak standard allocation power is lower than the off-peak standard allocation power.

[0009] By adopting the above technical solution, the community power management system accurately identifies the peak power consumption period and the off-peak power consumption period of the community according to the historical power consumption data of users in the community, and formulates a differential charging power allocation strategy accordingly. That is, during the peak power consumption period of the community, the control system will reduce the standard allocation power of the charging pile to relieve the grid pressure when the grid load of the community is high; while during the off-peak power consumption period of the community, the control system can increase the standard allocation power of the charging pile to encourage users to charge electric vehicles when the grid load of the community is low. This method based on data analysis and dynamic adjustment makes the allocation of power resources more accurate and reasonable, which can not only balance the grid load, but also guide users to form the habit of charging during off-peak hours, so as to better utilize power resources.

[0010] In connection with some embodiments of the first aspect, in some embodiments, if the usage power of other charging piles is less than the peak standard allocation power, then allocating the difference power of the other charging piles to the target charging pile to obtain the supplementary configured power of the target charging pile, where the difference power is used to represent the difference between the peak standard allocation power and the usage power, and specifically includes: obtaining the current difference power of each other charging pile, where the difference power is used to represent the difference between the peak standard allocation power and the usage power; allocating the current difference power of each other charging pile to the target charging pile; based on the current difference power of each other charging pile and the peak standard allocation power of the target charging pile, determining the supplementary configured power of the target charging pile.

[0011] By adopting the above technical solution, the community power management system calculates the differential power of each charging pile in real time and dynamically allocates these underutilized differential powers to the target charging piles with higher power consumption demands, so as to meet the power consumption demands of users for electric vehicle charging to a greater extent without increasing the overall power consumption load. This method maximally utilizes the differential powers of other charging piles through a refined power allocation method, not only improving the utilization efficiency of charging facilities, but also being able to flexibly allocate power resources during peak electricity consumption periods in the community, effectively alleviating local charging pressure. At the same time, this dynamic allocation mechanism can also quickly respond to changes in power consumption demands, providing users with more flexible and efficient charging services. In addition, this method can also promote the fair utilization of charging resources, avoiding the situation where some charging piles are idle for a long time while others are in short supply, thereby improving user satisfaction and the operation efficiency of the entire community power grid.

[0012] Combined with some embodiments of the first aspect, in some embodiments, if the additional configured power of the target charging pile is less than the planned charging power, then within the first charging duration, the electric vehicle is charged based on the additional configured power, which specifically includes: when the additional configured power of the target charging pile is less than the planned charging power, real-time monitoring whether the differential power of other charging piles changes; when obtaining the current differential power of each other charging pile, recording the first moment; when there is a change in the differential power of other charging piles, recording the second moment; determining the first charging duration based on the first moment and the second moment; and within the first charging duration, charging the electric vehicle based on the additional configured power.

[0013] By adopting the above technical solution, the community power management system continuously monitors the changes in the differential power of other charging piles and promptly captures the increase in available power, thereby quickly adjusting the charging strategy, which can not only maximize the utilization of idle charging resources, but also perform instant optimization according to the actual situation during the charging process. By accurately recording the charging duration, the community power management system can accurately calculate the actual charging amount, providing an accurate basis for the adjustment of subsequent charging plans. This dynamic response mechanism can effectively respond to the real-time changes in the electricity consumption situation in the community, while ensuring the power consumption demands of users, and also maintaining the stable operation of the power grid.

[0014] In some embodiments in combination with some embodiments of the first aspect, after the step of obtaining the user's electricity demand when the electric vehicle is connected to the target charging pile, where the electricity demand includes the planned charging amount and the planned charging duration, the method further includes: if the first duration in the planned charging duration is during the peak period of the community's electricity consumption and the second duration is during the valley period of the community's electricity consumption, then during the first duration, charge the electric vehicle based on the peak standard distribution power of the target charging pile, and the sum of the first duration and the second duration is equal to the planned charging duration; determine the charging power for the second charging duration according to the first duration, the peak standard distribution power of the target charging pile, and the planned charging amount.

[0015] By adopting the above technical solution, when the first duration in the planned charging duration is during the peak period of the community's electricity consumption and the second duration is during the valley period of the community's electricity consumption, during the peak period of the community's electricity consumption, the community power management system will distribute power based on the peak standard of the charging pile to relieve the pressure on the community power grid; while during the valley period of the community's electricity consumption, the community power management system can increase the charging power to speed up the charging speed, ensuring that the user's electricity demand is met throughout the charging process without causing too much pressure on the power grid. This charging strategy that spans the peak and valley periods of the community's electricity consumption fully considers the dynamic changes in the power grid load, realizes a more intelligent and efficient charging management, not only can balance the power grid load, but also can maximize the utilization of power resources.

[0016] In some embodiments in combination with some embodiments of the first aspect, after the step of obtaining the user's electricity demand when the electric vehicle is connected to the target charging pile, where the electricity demand includes the planned charging amount and the planned charging duration, the method further includes: if the planned charging duration is during the valley period of the community's electricity consumption, charge the electric vehicle based on the planned charging power.

[0017] By adopting the above technical solution, during the valley period of the community's electricity consumption, the load pressure on the community power grid is relatively small, allowing for a higher charging power. At this time, the community power management system can directly charge according to the user's planned charging power without complex power distribution calculations, thereby effectively utilizing the abundant power resources during the valley period of the community's electricity consumption. At the same time, this strategy also encourages users to charge their electric vehicles when the community power grid load is low, which helps to balance the overall power grid load and improve the utilization rate of power grid resources. In the long run, this method can guide the formation of a more reasonable electric vehicle power consumption pattern, reduce the pressure during the peak period of the community's electricity consumption, and improve the electricity consumption efficiency of the entire community. In addition, for users, charging during the valley period of the community's electricity consumption usually means a lower electricity price, so this strategy can also help users reduce the charging cost and improve the economy of using electric vehicles.

[0018] In combination with some embodiments of the first aspect, in some embodiments, after the step of, if there are other charging piles with a usage power less than the peak standard allocation power, allocating the difference power of the other charging piles to the target charging pile to obtain the supplementary configured power of the target charging pile, the method further includes: real-time monitoring of the voltage parameter and current parameter of the target charging pile; when the voltage parameter is not within the preset voltage range or the current parameter is not within the preset current range, determining whether the user has a charging power deception behavior, where the charging power deception behavior is used to represent the behavior of the user deceiving the community power management system through technical means to obtain a charging power higher than the supplementary configured power; if so, stopping charging the electric vehicle and locking the user information.

[0019] By adopting the above technical solution, this real-time monitoring and anti-deception mechanism greatly improves the security and reliability of the community power management system. By continuously monitoring the voltage parameter and current parameter of the target charging pile, the community power management system can promptly detect abnormal situations and prevent users from overusing electricity through technical means, which not only protects the safety of the community power grid but also ensures the fair distribution of power resources. Once it is detected that the user has a charging power deception behavior, the community power management system will immediately take measures, including stopping charging and locking the user information, to effectively prevent the continuous occurrence of improper behaviors.

[0020] In a second aspect, an embodiment of the present application provides a community power management system, which includes: one or more processors and a memory; the memory is coupled to the one or more processors, and the memory is used to store computer program code, and the computer program code includes computer instructions, and the one or more processors call the computer instructions to enable the community power management system to execute the method described in the first aspect and any possible implementation manner in the first aspect.

[0021] In a third aspect, an embodiment of the present application provides a computer program product containing instructions, which, when the computer program product runs on a community power management system, enables the community power management system to execute the method described in the first aspect and any possible implementation manner in the first aspect.

[0022] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, including instructions, which, when the instructions run on a community power management system, enable the community power management system to execute the method described in the first aspect and any possible implementation manner in the first aspect.

[0023] Understandably, the community power management system provided in the second aspect above, the computer program product provided in the third aspect, and the computer storage medium provided in the fourth aspect are all used to execute the method provided in the embodiments of the present application.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. As used in the specification of the present application, the singular forms "a", "an", "the above", "the", and "this" are also intended to include the plural forms unless the context clearly indicates otherwise.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0030] The following is a process description of the method provided in this embodiment. Please refer to Figure 1 , which is a schematic flowchart of the method for allocating the charging power of electric vehicles in a community in the embodiments of the present application.

[0031] S101. When an electric vehicle is connected to a target charging pile, obtain the user's electricity demand, which includes the planned charging amount and the planned charging duration, and the planned charging duration is during the peak electricity consumption period of the community; Herein, an electric vehicle refers to a vehicle powered by a rechargeable battery; a target charging pile refers to the charging device that is currently charging the electric vehicle; electricity demand refers to the specific requirements of the user for charging the electric vehicle; the planned charging amount refers to the amount of electricity that the user hopes to charge into the electric vehicle, usually in kilowatt-hours (kWh); the planned charging duration refers to the time when the user expects the electric vehicle to complete charging, usually in hours; the peak electricity consumption period of the community refers to the time period with relatively large electricity consumption in the community within a day, such as from 7 pm to 11 pm.

[0032] When the electric vehicle drives into the community and is connected to the target charging pile, the community power management system starts to execute this step. Specifically, first, the community power management system identifies that the electric vehicle is connected to the target charging pile, and then, the community power management system obtains the user's electricity demand through the user interface (such as the display screen of the target charging pile, APP, etc.) or the preset user preferences (determined according to the user's historical charging data). The community power management system will require the user to input or confirm the planned charging amount and the planned charging duration. In addition, the community power management system will also check whether the planned charging duration specified by the user is during the peak electricity consumption period of the community. If so, the community power management system will record this information to prepare for subsequent charging power allocation.

[0033] S102. Determine the planned charging power according to the planned charging amount and the planned charging duration; After obtaining the user's electricity demand, the community power management system immediately executes this step. Specifically, the community power management system uses simple mathematical calculations to determine the planned charging power. The planned charging power refers to the ideal charging power required to meet the user's electricity demand, usually measured in kilowatts (kW). The community power management system divides the planned charge by the planned charging duration to obtain the planned charging power. For example, if the planned charge is 40 kWh and the planned charging duration is 4 hours, the planned charging power is 10 kW. The community power management system may consider the charging efficiency factor and may slightly increase the calculated planned charging power to compensate for the energy loss during the charging process.

[0034] S103. If the planned charging power exceeds the peak standard allocation power of the target charging pile, obtain the usage power of other charging piles. Among them, the peak standard allocation power refers to the standard power allocated to each charging pile during the peak electricity consumption period in the community; other charging piles refer to all charging devices except the target charging pile; the usage power refers to the current charging power of other charging piles.

[0035] When the community power management system calculates the planned charging power, it immediately executes this step. Specifically, first, the community power management system compares the planned charging power with the peak standard allocation power of the target charging pile. If the planned charging power is higher, the community power management system believes that the target charging pile cannot meet the user's electricity demand with the peak standard allocation power. At this time, the community power management system will start collecting the real-time usage of all other charging piles, that is, obtain the usage power of other charging piles. The community power management system will query the current usage power of each other charging pile, including those that are charging and those that are in an idle state.

[0036] S104. If there is other charging pile whose usage power is less than the peak standard allocation power, allocate the difference power of this other charging pile to the target charging pile to obtain the supplementary configuration power of the target charging pile. The difference power is used to represent the difference between the peak standard allocation power and the usage power. Among them, the difference power represents the difference between the peak standard allocation power and the usage power of other charging piles; the supplementary configuration power refers to the new available power obtained by the target charging pile based on the original peak standard allocation power by allocating the difference power of other charging piles.

[0037] After obtaining the usage power of other charging piles, the community power management system immediately executes this step. Specifically, first, the community power management system compares the usage power of each other charging pile with the peak standard allocation power. For other charging piles with usage power lower than the peak standard allocation power, the community power management system calculates the differential power. Then, the community power management system accumulates these differential powers and allocates them to the target charging pile. For example, if there are three other charging piles with differential powers of 2kW, 3kW, and 1kW respectively, a total of 6kW can be allocated to the target charging pile. The community power management system adds this 6kW to the peak standard allocation power of the target charging pile to obtain the supplementary configuration power.

[0038] S105. If the supplementary configuration power of the target charging pile is greater than the planned charging power, then within the planned charging duration, charge the electric vehicle based on the planned charging power; When the community power management system calculates the supplementary configuration power of the target charging pile, it immediately executes this step. Specifically, first, the community power management system compares the magnitudes of the supplementary configuration power and the planned charging power. If the supplementary configuration power is greater than the planned charging power, it indicates that the community power management system is capable of meeting or even exceeding the user's original power consumption demand. In this case, the community power management system chooses to charge according to the planned charging power initially set by the user, rather than using the higher supplementary configuration power. The reasons for this are: (1) It can precisely meet the user's power consumption demand without causing unnecessary energy waste; (2) It can reserve some power margin to cope with possible power grid fluctuations or other power consumption demands. The community power management system will precisely control the charging process to ensure a stable charging power throughout the planned charging duration. For example, if the user plans to charge at a power of 7kW for 4 hours, even if the supplementary configuration power reaches 9kW, the community power management system controls the target charging pile to charge the electric vehicle at a charging power of 7kW. At the same time, the community power management system will continuously monitor the charging process to ensure that the charging amount reaches the planned charging amount and stop in a timely manner when the charging is completed.

[0039] S106. If the supplementary configuration power of the target charging pile is less than the planned charging power, then within the first charging duration, charge the electric vehicle based on the supplementary configuration power; When the community power management system discovers that the supplementary configured power of the target charging pile is less than the planned charging power, this step is immediately executed. Specifically, the community power management system determines that it cannot fully meet the user's original electricity demand, and controls the target charging pile to charge the electric vehicle with the supplementary configured power first. During the entire charging process, the community power management system will continuously monitor the charging status to ensure that the charging power is stable at the supplementary configured power. At the same time, the community power management system will also monitor the change in the differential power of other charging piles. If there is an opportunity to increase the power to charge the electric vehicle during the charging process (such as other charging piles releasing more differential power), the community power management system will adjust in a timely manner to shorten the charging time of the electric vehicle. That is, the community power management system will calculate the charging duration of the target charging pile to charge the electric vehicle with the supplementary configured power, that is, the first charging duration. The timing starts when the target charging pile charges the electric vehicle with the supplementary configured power and stops when the differential power of other charging piles changes, thus obtaining the first charging duration. For example, if the user originally planned to charge at a power of 10 kW for 4 hours (i.e., charge 40 kWh), but the supplementary configured power is only 8 kW, and the community power management system detects that the differential power of other charging piles changes after 20 minutes, then the community power management system will control the target charging pile to charge the electric vehicle with the supplementary configured power of 8 kW in the first 20 minutes. In addition, the community power management system will calculate the charged electricity in real time to ensure that the planned charging amount of the user's electricity demand is finally reached. When the charging is nearly completed, the community power management system may slightly reduce the charging power of the target charging pile to accurately reach the planned charging amount and avoid overcharging.

[0040] S107. Determine the remaining charging amount of the electric vehicle according to the first charging duration, the supplementary configured power, and the planned charging amount; When the community power management system calculates the first round of charging power distribution, that is, after the end of the first charging duration, the community power management system immediately executes this step. Specifically, first, the community power management system calculates the electricity actually charged during the first charging duration. The calculation method is to multiply the supplementary configured power by the first charging duration. For example, if the supplementary configured power is 8 kW and the first charging duration is 2 hours, then the actually charged electricity is 20 kWh. Then, the community power management system compares this actually charged electricity with the initial planned charging amount. If the planned charging amount is 50 kWh, then the remaining charging amount is 30 kWh. The community power management system will accurately calculate this remaining charging amount. Considering the charging efficiency and energy loss, the remaining charging amount may be slightly increased to ensure that it is finally fully charged.

[0041] S108. Use the remaining charge as the planned charge and the second charging duration as the planned charging duration, and continue to execute the steps after obtaining the user's power consumption demand when the electric vehicle is connected to the target charging pile until the remaining charge is 0, and the sum of the first charging duration and the second charging duration is the planned charging duration.

[0042] When the community power management system calculates the remaining charge, this step is immediately executed. Specifically, the community power management system sets the remaining charge as the new planned charge target and the second charging duration as the new planned charging duration target. For example, if the remaining charge is 10 kWh, the first charging duration is 2 hours, and the planned charging duration is 6 hours, then the second charging duration is 4 hours. The community power management system restarts the entire charging process as if the electric vehicle has just been connected to the target charging pile, which means that the community power management system will re-evaluate the current grid load situation in the community, collect the real-time usage of all other charging piles, that is, obtain the usage power of other charging piles, and try to allocate power for the next charging. The community power management system will repeatedly execute steps such as power allocation and charging control until the remaining charge drops to 0. During this process, the community power management system will continuously monitor the charging progress of the electric vehicle and may adjust the charging strategy multiple times according to the real-time situation. At the same time, the community power management system will continuously update the user interface to let the user know the latest charging status and the estimated completion time. When the remaining charge finally drops to 0, the community power management system will control the target charging pile to stop charging the electric vehicle and send a charging completion notification to the user.

[0043] By adopting the above technical solution, during the peak electricity consumption period in the community, if it is necessary to complete the planned charge within the planned charging duration, it may cause the planned charging power of the charging pile to exceed the current community load. Therefore, the community power management system can dynamically adjust the power allocation of other charging piles and allocate the differential power of other under-utilized charging piles to the target charging pile with a higher current power consumption demand, realizing the optimal utilization of power resources and effectively solving the contradiction between the power consumption demand of electric vehicles in the community and the power supply capacity of the power grid. At the same time, this method can also dynamically adjust the charging plan according to the actual charging situation to ensure that the electric vehicle can complete the charging of the electric vehicle within the user's planned charging duration, not only improving the charging efficiency but also balancing the grid load and avoiding the power supply pressure during the peak electricity consumption period. In addition, this method can adapt to different power consumption demands and grid conditions, providing more convenient and reliable charging services for users, and at the same time providing an efficient solution for community power management.

[0044] The following further describes the more specific process of the method provided in this embodiment. Please refer to Figure 2, which is another schematic flowchart of the method for allocating the charging power of electric vehicles in a community in the embodiment of the present application.

[0045] S201. Obtain the historical electricity consumption data of users in the community; based on the historical electricity consumption data, determine the peak electricity consumption period and the off-peak electricity consumption period of the community; determine the peak standard allocation power of the target charging pile during the peak electricity consumption period of the community and the off-peak standard allocation power of the target charging pile during the off-peak electricity consumption period of the community, where the peak standard allocation power is lower than the off-peak standard allocation power. Among them, the historical electricity consumption data refers to the electricity consumption records of all users in the community in the past period (such as the past month); the peak electricity consumption period of the community refers to the time period with a large electricity consumption in the community in a day, such as from 7 pm to 11 pm; the off-peak electricity consumption period of the community refers to the time period with a small electricity consumption in the community in a day, such as from 1 am to 5 am; the peak standard allocation power refers to the standard power allocated to each charging pile during the peak electricity consumption period of the community; the off-peak standard allocation power refers to the standard power allocated to each charging pile during the off-peak electricity consumption period of the community.

[0046] The community power management system executes this step before formulating the charging strategy. Specifically, first, the community management system extracts the historical electricity consumption data of all users in the community, usually including the electricity consumption records of the recent few months or even a year. The community power management system identifies the electricity consumption patterns in a day based on the historical electricity consumption data. For example, the electricity consumption peak is from 18:00 to 22:00, and the electricity consumption off-peak is from 1:00 am to 5:00 am. Based on these analysis results, the community power management system clearly defines the peak electricity consumption period and the off-peak electricity consumption period of the community. Next, the community power management system will consider factors such as the grid capacity and the number of charging piles to set the peak standard allocation power during the peak electricity consumption period of the community and the off-peak standard allocation power during the off-peak electricity consumption period of the community for each charging pile. For example, the community power management system may set the peak standard allocation power to 5 kW and the off-peak standard allocation power to 10 kW. This setting ensures that the community power grid will not be overloaded during the peak electricity consumption period of the community, and at the same time, the power resources can be used more efficiently during the off-peak electricity consumption period of the community. The community power management system will also update these settings regularly to adapt to seasonal changes and long-term changes in electricity consumption patterns.

[0047] S202. When an electric vehicle is connected to the target charging pile, obtain the user's electricity consumption demand, where the electricity consumption demand includes the planned charging amount and the planned charging duration, and the planned charging duration is during the peak electricity consumption period of the community. Specifically, reference can be made to step S101, which will not be elaborated here.

[0048] S203. If the first period in the planned charging duration is during the peak period of community electricity consumption and the second period is during the off-peak period of community electricity consumption, then during the first period, charge the electric vehicle based on the peak standard distribution power of the target charging pile. The sum of the first period and the second period is equal to the planned charging duration; determine the charging power for the second charging period according to the first period, the peak standard distribution power of the target charging pile, and the planned charging amount. When the community power management system detects that the user's planned charging duration spans the peak period and the off-peak period of community electricity consumption, this step is executed. Specifically, first, the community power management system divides the planned charging duration into two parts: the first period (during the peak period of community electricity consumption) and the second period (during the off-peak period of community electricity consumption). During the first period, the community power management system strictly controls the target charging pile to charge the electric vehicle according to the peak standard distribution power to relieve the pressure on the community power grid. At the end of the first period, the community power management system determines the remaining electricity to be charged into the electric vehicle, and then determines the charging power for controlling the target charging pile to charge the electric vehicle during the second period according to the second period. For example, the peak period of community electricity consumption is from 19:00 to 23:00, and the off-peak period of community electricity consumption is from 23:00 to 4:00 the next day. At 22:00, the user wants to charge the electric vehicle, and the planned charging duration is 6 hours. Then, 1 hour of the 6 hours is during the peak period of community electricity consumption, that is, the first period is 1 hour, and 5 hours are during the off-peak period of community electricity consumption, that is, the second period is 5 hours. If the peak standard distribution power is 5kW, then the electricity charged during this first period is 5kWh. Next, the community power management system calculates the remaining electricity to be charged after the end of the first period. Assuming the planned charging amount is 30kWh, then the remaining electricity to be charged is 25kWh. Then, the community power management system calculates the required charging power during the second period to ensure that the charging is completed at the end of the planned charging duration. The second period is 5 hours, so the required charging power is approximately 5kW (25kWh / 5 hours). The community power management system does not strictly limit whether the calculated charging power exceeds the off-peak standard distribution power because it is during the off-peak period of community electricity consumption and more power resources can be provided for electric vehicle charging. However, the community power management system will compare the calculated charging power with the maximum output power of the target charging pile to ensure that the target charging pile is not damaged.

[0049] S204. If the planned charging duration is during the off-peak period of community electricity consumption, charge the electric vehicle based on the planned charging power. When the community power management system confirms that the user's planned charging duration fully falls within the low electricity consumption period of the community, this step is executed. Specifically, the community power management system verifies whether the planned charging power requested by the user is within the allowable range, that is, it does not exceed the maximum output power of the charging pile. If the planned charging power is reasonable, the community power management system will directly charge the electric vehicle at this planned charging power. For example, if the user requests to charge at a power of 7 kW for 4 hours, the community power management system will maintain this 7 kW power for continuous charging. During the charging process, the community power management system will continuously monitor the charging status to ensure the stability of the charging power and calculate the charged electricity in real time. If there are changes in the load of the community power grid during the charging process, the community power management system may fine-tune the charging power, but will try to keep it close to the planned charging power. When the planned charging amount or planned charging duration is reached, the community power management system will automatically stop charging and notify the user.

[0050] S205. Determine the planned charging power according to the planned charging amount and the planned charging duration; Specifically, refer to step S102, which will not be elaborated here.

[0051] S206. If the planned charging power exceeds the peak standard allocation power of the target charging pile, obtain the usage power of other charging piles; Specifically, refer to step S103, which will not be elaborated here.

[0052] S207. Obtain the current differential power of each other charging pile, and the differential power is used to represent the difference between the peak standard allocation power and the usage power; The community power management system executes this step when allocating more power to the target charging pile. Specifically, first, the community power management system traverses all charging piles in the community except the target charging pile. For each other charging pile, the community power management system reads its current usage power. Then, the community power management system compares this usage power with the preset peak standard allocation power. If the usage power is lower than the peak standard allocation power, then the differential power is obtained by subtracting the usage power from the peak standard allocation power. For example, if the peak standard allocation power of a certain charging pile is 7 kW and it is currently only using 4 kW, then its differential power is 3 kW.

[0053] S208. Allocate the current differential power of each other charging pile to the target charging pile; After calculating the differential power of all other charging piles, the community power management system immediately executes this step. Specifically, first, the community power management system sums up the differential power of all other charging piles. For example, if there are 5 other charging piles with differential powers of 2kW, 1.5kW, 3kW, 0.5kW, and 1kW respectively, then the total differential power is 8kW. Then, the community power management system distributes this 8kW of total differential power to the target charging pile. During the distribution process, the community power management system considers multiple factors: (1) ensuring that the distribution does not exceed the maximum output power of the target charging pile; (2) considering the overall load situation of the community power grid and possibly reserving a part of the surplus power as a buffer; (3) evaluating the actual electricity consumption demand of users to avoid over-distribution. For example, if the target charging pile only needs an additional 5kW to meet the user's demand, then the community power management system may only distribute 5kW and reserve the remaining 3kW as power surplus.

[0054] S209. Determine the supplementary configuration power of the target charging pile based on the current differential power of each other charging pile and the peak standard distribution power of the target charging pile; After completing the distribution of the differential power, the community power management system immediately executes this step. Specifically, first, the community power management system adds up all the differential power distributed to the target charging pile to obtain the total differential power. Then, the community power management system adds this total differential power to the peak standard distribution power of the target charging pile to obtain the supplementary configuration power. For example, if the peak standard distribution power of the target charging pile is 5kW and the total differential power obtained from the distribution of other charging piles is 8kW, then the supplementary configuration power is 13kW. However, the community power management system also considers other factors when determining the final supplementary configuration power: (1) whether the supplementary configuration power exceeds the maximum output power of the charging pile, and if so, the supplementary configuration power will be limited within the maximum output power; (2) considering the actual electricity consumption demand of users, if the user only needs 10kW, then even if there is 13kW of available total differential power, the community power management system will only distribute 3kW to the target charging pile, that is, the supplementary configuration power is 13kW; (3) the community power management system will reserve a certain amount of power surplus to cope with emergencies and may set the final supplementary configuration power to 12kW. In addition, the community power management system also considers the overall load situation of the community power grid and slightly reduces the supplementary configuration power when necessary to ensure the stability of the community power grid.

[0055] S210. If the supplementary configuration power of the target charging pile is greater than the planned charging power, then charge the electric vehicle based on the planned charging power within the planned charging duration; Specifically, refer to step S105, which will not be elaborated here.

[0056] S211. If the supplementary configured power of the target charging pile is less than the planned charging power, monitor in real time whether the differential power of other charging piles changes; This step is executed when the community power management system finds that the supplementary configured power of the target charging pile is insufficient to meet the user's power consumption requirements. Specifically, first, the community power management system compares the supplementary configured power and the planned charging power. If the supplementary configured power is less than the planned charging power, the community power management system will start real-time monitoring, possibly checking the usage power of all other charging piles at a very high frequency (possibly every second or every few seconds). The community power management system will compare the current differential power of each charging pile with the previously recorded differential power, and any slight change will be captured. For example, if the differential power of another charging pile changes from 2 kW to 2.5 kW, the community power management system will immediately detect this 0.5 kW change.

[0057] S212. When obtaining the current differential power of each other charging pile, record the first moment; This step is executed when the community power management system first obtains the differential power data of all other charging piles. Specifically, the community power management system will send data requests to all other charging piles simultaneously to collect their current usage power. Then, the community power management system will compare these usage powers with the pre-set peak standard allocated power to calculate the differential power of each charging pile. At the moment when this series of operations is completed, the community power management system will record an accurate timestamp, which is the so-called "first moment". The accuracy of the timestamp may be accurate to the millisecond level, such as "2024-09-26 15:30:45.234". The community power management system will associate and store this timestamp with the obtained differential power, providing a reference point for subsequent time calculation and data analysis.

[0058] S213. When there is a change in the differential power of other charging piles, record the second moment; Among them, the change in differential power is used to indicate an increase or decrease in the difference between the peak standard allocated power and the usage power of other charging piles; the second moment is used to indicate the specific moment when the community power management system detects the change in differential power.

[0059] During the continuous monitoring process of the community power management system, this step is immediately executed once a change in the differential power of any other charging pile is detected. Specifically, the community power management system continuously compares the latest differential power of each charging pile with the previously recorded differential power. When the community power management system discovers a change in the differential power of one or more other charging piles, regardless of whether this change is an increase or a decrease, the system immediately records the current precise moment, which is the "second moment". For example, if during continuous monitoring, it is found that the differential power of an other charging pile changes from 1.5 kW to 2 kW, the community power management system will immediately capture this change and record the time point when the differential power change occurs, such as "2024-09-26 15:35:12.567". The community power management system not only records the second moment but also simultaneously records which other charging piles have changed and the magnitude of the change.

[0060] S214. Based on the first moment and the second moment, determine the first charging duration; After recording the first moment and the second moment, the community power management system immediately executes this step. Specifically, the community power management system uses an accurate time calculation function to subtract the time stamp of the first moment from the time stamp of the second moment to obtain the time difference between the two moments, and this time difference is the first charging duration. For example, if the first moment is "2024-09-26 15:30:45.234" and the second moment is "2024-09-26 15:35:12.567", then the community power management system will calculate that the first charging duration is 4 minutes, 27 seconds, and 333 milliseconds. The community power management system will convert this first charging duration into an appropriate unit (possibly minutes or hours) for subsequent charging plans.

[0061] S215. During the first charging duration, charge the electric vehicle based on the supplementary configured power; The community power management system immediately executes this step after determining the first charging duration. Specifically, the community power management system starts the charging program and adjusts the output power of the target charging pile to the previously calculated supplementary configured power. Assuming the supplementary configured power is 12 kW, the community power management system will ensure that the target charging pile continuously charges the electric vehicle at this supplementary configured power (12 kW). During the entire first charging duration (such as 4 minutes and 27 seconds), the community power management system will strictly monitor the charging process to ensure stable power output.

[0062] S216. According to the first charging duration, the supplementary configured power, and the planned charging amount, determine the remaining charging amount of the electric vehicle; Specifically, refer to step S107, which will not be elaborated here.

[0063] S217. Use the remaining charge as the planned charge and the second charging duration as the planned charging duration, and continue to execute the steps after obtaining the user's electricity demand when the electric vehicle is connected to the target charging pile until the remaining charge is 0. The sum of the first charging duration and the second charging duration is the planned charging duration; Specifically, refer to step S108, which will not be elaborated here.

[0064] S218. Real-time monitor the voltage parameters and current parameters of the target charging pile; when the voltage parameter is not within the preset voltage range or the current parameter is not within the preset current range, determine whether the user has a charging power deception behavior, where the charging power deception behavior refers to the behavior of the user deceiving the community power management system through technical means to obtain a charging power higher than the supplementary configured power; if it exists, stop charging the electric vehicle and lock the user information.

[0065] Among them, the voltage parameter refers to the voltage value output by the target charging pile during the charging process. The current parameter refers to the current value output by the target charging pile during the charging process. The preset voltage range refers to the normal charging voltage range preset by the community, usually 220V ± 10%. The preset current range represents the normal charging current range preset by the community. The charging power deception behavior refers to the behavior of the user deceiving the community power management system through technical means, such as modifying the charging pile or tampering with charging data, to obtain a charging power exceeding the charging power allocated by the community power management system. Locking the user information means temporarily freezing the account of the user with the charging power deception behavior and prohibiting them from using the community power grid.

[0066] This step is continuously executed after the electric vehicle starts charging, aiming to monitor the safety and compliance of the charging process. Specifically, the community power management system collects the voltage parameters and current parameters during the charging process in real time through sensors installed on the target charging pile, with a frequency of up to multiple times per second. The community power management system compares the collected voltage parameters of the target charging pile with the preset voltage range and compares the current parameters of the target charging pile with the preset current range. If the voltage parameter is not within the preset voltage range or the current parameter is not within the preset current range, the community power management system will immediately start an abnormal analysis program. The abnormal analysis program will consider multiple factors, such as the duration of the abnormality, the deviation degree, the historical charging record, etc., to determine whether there is a human charging power deception behavior. If the community power management system determines that there is a charging power deception behavior, it will control the target charging pile to stop charging the electric vehicle. At the same time, the community power management system will mark the account information of the involved user as "abnormal" and temporarily prohibit the user from using the community power grid.

[0067] In implementing the present invention, since the methods of dynamic power distribution and real-time monitoring are adopted, the present invention can flexibly allocate power resources during the peak electricity consumption period in the community, effectively solving the problems of resource waste and supply-demand contradiction caused by fixed power distribution in the related art, and thus achieving the efficient utilization of power resources and the timely satisfaction of users' electricity consumption demands. Since the differential charging strategy based on historical data analysis is adopted, the present invention can accurately identify the peak electricity consumption period and the low electricity consumption period in the community, effectively solving the problem of unbalanced grid load caused by unreasonable charging time selection in the related art, and thus achieving the balance of the grid load and the optimized guidance of users' charging behaviors. Since the methods of dynamically adjusting the charging plan and accurately calculating the charging amount are adopted, the present invention can flexibly adjust the charging strategy according to the actual charging situation, effectively solving the problems of unmet users' electricity consumption demands or low charging efficiency caused by fixed charging plans in the related art, and thus achieving the intelligent management of the charging process and the significant improvement of users' experience.
