Description

Technical Field

[0001] This application relates to the field of electric vehicle charging technology, and in particular to a flexible charging scheduling method, device, equipment and storage medium for car charging piles. Background Technology

[0002] With the increasing popularity of new energy vehicles, the construction and operation of charging stations have become crucial for ensuring their normal use. However, the carrying capacity of a single three-phase circuit in a charging station is limited. Taking a 7kW charging pile three-phase circuit as an example, with a fuse rated current of 225A, according to relevant electrical standards and safety regulations, a single-phase line can only support a maximum of seven charging piles simultaneously outputting 7kW of power. However, with the continuous growth in the number of new energy vehicles, the demand for charging facilities is increasing rapidly, and the existing number of charging spaces is insufficient to meet actual needs. Therefore, there is an urgent need to expand the existing three-phase circuit with more charging piles. In this process, it is essential to ensure that the circuit does not overload even when all charging piles are simultaneously in use. Overload will cause the entire line to lose power, which will not only affect the normal charging process of vehicles currently charging but may also damage charging equipment and the power grid, posing a serious safety hazard.

[0003] Currently, 7kW AC charging piles only support output power adjustment before charging begins, with the adjustment range typically between 3.5kW and 7kW. The 3.5kW power setting primarily considers the existence of slow charging ports for new energy vehicles that only support 3.5kW. Lowering the power would significantly impact the user's charging experience, leading to excessively long charging times and failing to meet users' fast charging needs. If the power isn't adjusted appropriately during charging, the charging pile will discharge at the currently set power, undoubtedly increasing the risk of line overload. Without proper power adjustment measures, the charging pile will continue to discharge at the current set power. If all charging piles operate at high power simultaneously, it can easily lead to line overload, potentially causing a power outage. This not only causes significant inconvenience to users charging, affecting their travel plans, but may also damage the charging equipment, increasing maintenance costs and operational risks. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a flexible charging scheduling method, device, equipment, and storage medium for car charging piles. When expanding the number of charging piles, the power of the charging piles can be dynamically adjusted according to the actual carrying capacity of the line, avoiding line overload, ensuring normal charging, and reducing safety hazards and equipment damage risks.

[0005] The first aspect of this application provides a flexible charging scheduling method for vehicle charging piles, the method comprising: Acquire parking space detection data for each parking space distributed by the parking space detector, and charging pile data for each charging pile; Determine the correspondence data between the parking space detector and each charging pile; When it is determined from the parking space detection data that a vehicle has entered the target parking space, the remaining current carrying capacity of the current carrying pool corresponding to the target charging pile is determined from the corresponding relationship data; the current carrying pool is a total current capacity pool set according to the maximum single-phase current carrying capacity of the station line; the target parking space is any parking space, and the target charging pile is the charging pile corresponding to the target parking space; Match the corresponding scheduling rule according to the remaining current carrying capacity of the current carrying pool; The scheduling instruction data is generated according to the scheduling rules, and the scheduling instruction data is sent to the target charging pile so that the target charging pile can modify its output power when it receives the scheduling instruction data.

[0006] In an optional implementation, the scheduling rule includes a first scheduling rule and a second scheduling rule. When the remaining current carrying capacity of the current carrying pool is greater than or equal to a preset current carrying capacity, the scheduling rule is determined to be the first scheduling rule. When the remaining current carrying capacity of the current carrying pool is equal to 0A, the scheduling rule is determined to be the second scheduling rule.

[0007] In an optional implementation, when the scheduling rule is determined to be the first scheduling rule, the first scheduling rule includes: Obtain the priority of each parking space, and set the output power of the charging pile corresponding to the highest priority parking space to 0; The output power of the target charging pile is set to the sum of the power corresponding to the remaining current value and the power corresponding to the fixed allocated current; the fixed allocated current is the current that can be allocated to each charging pile.

[0008] In an optional implementation, after setting the output power of the target charging pile to the sum of the power corresponding to the remaining current value and the power corresponding to the fixed allocated current, the method further includes... When it is determined that the target charging pile meets the preset conditions, the output power of the target charging pile is adjusted to the minimum output power; Adjust the output power of the charging pile corresponding to the highest priority parking space to the minimum output power setting.

[0009] In an optional implementation, the preset condition is that the target charging pile has not received a user charging order instruction for more than a preset time period or has detected a vehicle leaving the target parking space within the preset time period, or a combination thereof.

[0010] In an optional implementation, when the scheduling rule is determined to be the second scheduling rule, the second scheduling rule includes: Identify the charging pile that started charging earliest and is at full load output among all the charging piles, and suspend charging of the charging pile that started charging earliest and is at full load output. Adjust the output power of the earliest charging pile that started charging and was at full load to the lowest output power, and start charging the earliest charging pile that started charging and was at full load. Set the output power of the target charging pile to the minimum output power.

[0011] In an optional implementation, after setting the output power of the target charging station to the minimum output power, the method further includes: When it is determined that the target charging pile meets the preset conditions, the charging of the earliest charging pile that started charging and was at full load output is suspended. Set the output power of the earliest charging pile that starts charging and is at full load to the maximum output power, and start charging the earliest charging pile that starts charging and is at full load.

[0012] A second aspect of this application provides a flexible charging scheduling device for vehicle charging piles, the device comprising: The data acquisition module is used to acquire parking space detection data for each parking space distributed by the parking space detector, as well as charging pile data for each charging pile. The correspondence determination module is used to determine the correspondence data between the parking space detector and each charging pile; The remaining current carrying capacity determination module is used to determine the remaining current carrying capacity of the current carrying pool corresponding to the target charging pile based on the corresponding relationship data when it is determined from the parking space detection data that there is vehicle entry data in the target parking space; the current carrying pool is a total current capacity pool set according to the maximum single-phase current carrying capacity of the station line; the target parking space is any parking space, and the target charging pile is the charging pile corresponding to the target parking space; The scheduling rule matching module is used to match the corresponding scheduling rule based on the remaining current carrying capacity of the current carrying pool. The instruction generation and distribution module is used to generate scheduling instruction data according to the scheduling rules and distribute the scheduling instruction data to the target charging pile, so that the target charging pile can modify its output power when it receives the scheduling instruction data.

[0013] A third aspect of this application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the flexible charging scheduling method for car charging piles.

[0014] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the above-described flexible charging scheduling method for vehicle charging piles.

[0015] In summary, the flexible charging scheduling method, device, equipment, and storage medium for electric vehicle charging piles provided in this application acquire parking space detection data for each parking space and charging pile data for each charging pile distributed by the parking space detector, and determine the correspondence between the parking space detector and each charging pile. When a vehicle enters the target parking space, the remaining current carrying capacity of the current-carrying pool corresponding to the target charging pile is determined based on the correspondence data. The current-carrying pool is set based on the maximum single-phase current carrying capacity of the station line, which can intuitively reflect the current capacity that the current-carrying line can currently bear. The corresponding scheduling rules are matched according to the remaining current carrying capacity of the current-carrying pool, and different remaining current carrying capacities correspond to different scheduling strategies to ensure that the scheduling is scientific and reasonable. When a vehicle enters the parking space to start charging, the charging pile will not discharge according to the initial set power, but will dynamically adjust the output power according to the actual remaining current carrying capacity of the line. This avoids the situation where all charging piles operate at high power at the same time, which would cause the line to overload. Thus, it not only meets the need to expand more charging piles on the original three-phase line circuit, but also ensures that the circuit will not be overloaded, ensuring the normal charging process of the vehicle being charged, and reducing the risk of damage to charging equipment and the power grid.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0019] Reference Figure 1 The diagram shown is a structural schematic of a flexible charging scheduling system for car charging piles according to an embodiment of this application. The flexible charging scheduling system for car charging piles includes a parking space detector, a parking space detector backend system, an intelligent scheduling center system, an AC charging pile, and a charging pile backend system.

[0020] To facilitate understanding of the inventive concept of this application, the following embodiments use a 7kW AC charging pile as an example, and Community A (i.e., the charging station) as an example for illustration. Here, 7kW is the highest output power of the AC charging pile, and 3.5kW is the lowest output power. The 7kW AC charging pile has an output power adjustment function, which can only be executed before the charging operation is started. The adjustment range of the output power is set from 3.5kW to 7kW. The 3.5kW power value is set based on the current market situation where there are slow charging interfaces for new energy vehicles that only adapt to 3.5kW power input. If the output power is lower than 3.5kW, it will significantly reduce the user's charging experience; therefore, 3.5kW is used as the lower limit of the output power adjustment range.

[0021] Refer to together Figure 2 The parking space detector connects to its backend system via mobile IoT communication. The backend system connects to the intelligent dispatch center system via a data transmission interface (such as HTTP, WebSocket, etc., depending on the actual system design). The 7kW AC charging pile connects to its backend system via mobile IoT communication. The backend system connects to the intelligent dispatch center system via a data interaction interface (such as API interface, depending on the actual system design). Based on mobile IoT communication, the parking space detector can generate and distribute parking space detection data, the 7kW AC charging pile can generate and distribute charging pile data, the intelligent dispatch center system can generate and distribute flexible intelligent charging dispatch schemes, and the 7kW AC charging pile can execute these schemes.

[0022] Parking space detectors are installed above each parking space (or in other suitable locations to effectively detect parking space status). They use infrared laser detectors to detect whether a vehicle is parked or has left the space. By default, each parking space detector generates one MQTT message per minute, representing parking space detection data. This data includes at least the parking space status (vacant, occupied). When the detection status changes (i.e., a parking space changes from vacant to occupied, or vice versa), the parking space detector immediately pushes the data to its backend system. Specifically, if a vehicle enters or is present in a parking space, an MQTT message indicating the space is occupied is automatically generated and pushed to the backend system; if no vehicle is present or a vehicle has left, an MQTT message indicating the space is vacant is automatically generated and pushed to the backend system. This allows the backend system to aggregate message data from all parking space detectors in Community A and push this data to the intelligent dispatch center in real time.

[0023] Meanwhile, the charging pile backend system can pre-establish the correspondence data between parking space detectors and 7kW AC charging piles, as well as the maximum current carrying capacity of a single phase of the site's line (also known as the maximum current carrying capacity of a single phase of the site's line), and set the output power of all charging piles on the line at that site to 3.5kW. The correspondence data refers to associating the device code of the parking space detector with the device code of the charging pile; the maximum current carrying capacity of a single phase of the site's line comes from the actual current carrying capacity of the three-phase line constructed at the site, such as a 90 square millimeter wire with a maximum single-phase current carrying capacity of approximately 210A. Similarly, the charging pile generates one MQTT message per minute via a communication module (e.g., a 4G module), which is the charging pile data. The charging pile data includes at least the charging status (charging in progress, idle) and the charging current (xxA). The charging pile pushes the charging pile data to the charging pile backend system in real time, enabling the charging pile backend system to aggregate the message data of all charging piles in Community A and push this message data to the intelligent dispatch center in real time. In addition, the charging pile backend system also synchronizes the correspondence data and the maximum current carrying capacity of a single phase of the site's line to the intelligent dispatch center.

[0024] Upon receiving the maximum single-phase current carrying capacity of the charging pile's line from the charging pile's backend system (due to the characteristics of AC three-phase lines, a single phase cannot be overloaded), the intelligent dispatch center sets up a corresponding current carrying capacity pool (total current X, unit A). By default, each charging pile on that phase line can be allocated a current carrying capacity of 16A, and the dispatch value is fixed at 16A. That is, for a single line at that site, the current carrying capacity pool = the maximum single-phase current carrying capacity of the line (the maximum current carrying capacity of a 90 square millimeter wire is 210A).

[0025] Next, when the intelligent dispatch center receives data from the detector platform system indicating that a vehicle has entered parking space A, it means that the parking space was previously vacant and charging pile C1 was not charging. The intelligent dispatch center immediately formulates a dispatch strategy, such as pre-allocating the current carrying capacity of one charging pile DU1 to charging pile C1 to ensure that charging pile C1 can output a minimum of 3.5kW of power. Based on the specified dispatch strategy, the intelligent dispatch center generates a dispatch command and sends it to the charging pile's backend system. Upon receiving the dispatch command, the charging pile's backend system generates MQTT command data and sends it to the corresponding charging pile. Upon receiving the MQTT command data, the charging pile adjusts its output power accordingly.

[0026] The intelligent dispatch center system is integrated into any electronic device. To facilitate understanding of the inventive concept of this application, the following embodiments all use the intelligent dispatch center as the executing entity to describe in detail the flexible charging dispatch method for car charging piles. (Refer to...) Figure 3 The diagram shown is a flowchart illustrating a flexible charging scheduling method for car charging piles according to an embodiment of this application. The flexible charging scheduling method for car charging piles includes the following steps.

[0027] S31, acquire parking space detection data for each parking space distributed by the parking space detector, and charging pile data for each charging pile.

[0028] S32, determine the correspondence data between the parking space detector and each charging pile.

[0029] In some embodiments, the parking space detector uses an infrared laser detector to detect parking spaces in real time to determine whether a vehicle is parked or has left the space. The parking space detector employs a specific detection mechanism for data generation and push. Specifically, the parking space detector generates one MQTT message (i.e., parking space detection data) per minute by default. This message contains at least parking space status information, i.e., whether the parking space is vacant or occupied. When the parking space status detected by the parking space detector changes, it immediately pushes the data to the parking space detector's backend system. Further, if a vehicle enters the parking space or there is already a vehicle in the space, the parking space detector automatically generates an MQTT message indicating that the parking space is occupied and pushes it to the parking space detector's backend system; if there is no vehicle in the parking space or a vehicle has left the parking space, the parking space detector automatically generates an MQTT message indicating that the parking space is vacant and pushes it to the parking space detector's backend system.

[0030] The parking space detector backend system is responsible for data aggregation, summarizing and organizing the message data sent by all parking space detectors in Community A. After aggregation, the parking space detector backend system pushes the aggregated message data to the intelligent dispatch center in real time, so that the intelligent dispatch center can obtain the status information of each parking space in the community in a timely manner, providing an accurate data basis for subsequent operations such as charging scheduling.

[0031] Meanwhile, to achieve effective management and data interaction of charging piles, the charging pile backend system allows for basic data settings. Specifically, it establishes a correspondence between parking space detectors and charging piles, linking the device codes of the parking space detectors and charging piles, enabling the system to accurately identify the charging pile corresponding to each parking space. Simultaneously, it sets the maximum current-carrying value for a single phase of the station's wiring. This value limits the maximum current the line can withstand, ensuring safe and stable operation. The maximum current-carrying value for a single phase of the station's wiring comes from the actual current-carrying value of the three-phase wiring installed at the site; for example, a 90 square millimeter wire has a maximum single-phase current-carrying capacity of approximately 210A. Furthermore, it sets a command for all charging piles on the station's wiring to have an output power of 3.5kW, providing a standard for the initial power setting of the charging piles.

[0032] After completing the above basic settings, the charging pile enters the data generation and push phase. The charging pile uses its built-in 4G module to generate MQTT messages (i.e., charging pile data) containing key information such as charging status (charging in progress, idle) and charging current (xxA) at a frequency of one message per minute. After generating the message, the charging pile pushes this message data to the charging pile's backend system in real time, ensuring that the backend system can promptly obtain the charging pile's real-time operating status.

[0033] After receiving the message data pushed by each charging pile, the charging pile backend system takes on the task of data aggregation, centrally organizes the message data of all charging piles in the community, forms a complete and comprehensive charging pile operation data set, and pushes the aggregated message data to the intelligent dispatch center in real time.

[0034] S33, when it is determined from the parking space detection data that there is vehicle entry data in the target parking space, the remaining current carrying capacity of the current carrying pool corresponding to the target charging pile is determined from the corresponding relationship data.

[0035] Wherein, the current-carrying pool is a total current capacity pool set according to the maximum single-phase current carrying value of the station line; the target parking space is any parking space, and the target charging pile is the charging pile corresponding to the target parking space.

[0036] In some embodiments, to ensure the safe and stable operation of the charging station lines during charging, and to achieve reasonable allocation and efficient utilization of charging resources, the intelligent dispatch center receives information on the maximum single-phase current carrying capacity of the charging station lines pushed by the charging pile backend system. This information clarifies the maximum current limit that the single-phase line can withstand. Based on the received maximum single-phase current carrying capacity, the intelligent dispatch center can set up a corresponding current-carrying pool. The total current of the current-carrying pool is set to the maximum single-phase current carrying capacity, denoted as total current X, in amperes (A), ensuring that the capacity of the current-carrying pool will not exceed the maximum carrying capacity of the single-phase line, thus avoiding the risk of overload from the source.

[0037] In terms of current allocation, to ensure fairness and stability, each charging pile on this phase line is allocated a current of 16A by default, and the scheduling value is fixed at 16A. That is, in the initial state, no matter how many charging piles are connected to this phase line, each charging pile will carry out charging operations according to a current of 16A unless affected by special scheduling instructions.

[0038] Because the parking space detector continuously monitors each parking space in real time to determine whether a vehicle is parked or has left the space, the intelligent dispatch center receives message data pushed by the parking space detector's backend system in real time. When it is determined that a vehicle has entered a certain parking space (for ease of distinction, it is called the target parking space, hereinafter referred to as parking space A), due to the detection mechanism of the parking space detector, it can be determined that the target parking space was previously vacant, and at this time the corresponding target charging pile C1 is not performing charging operations.

[0039] Furthermore, the corresponding data clarifies which single-phase line each charging pile is connected to at the community charging station. Different charging piles may be distributed across different single-phase lines, and the current-carrying pool is set up and managed according to the single-phase line of the station, with each current-carrying pool corresponding to a specific single-phase line. Only by clarifying the line to which each charging pile belongs can the corresponding current-carrying pool information be accurately obtained. After determining the line to which the target charging pile belongs, combined with the maximum single-phase current-carrying value setting information pushed by the charging pile's backend system, the maximum current-carrying capacity of the current-carrying pool for that line and the currently allocated current-carrying status can be accurately obtained. For example, if the maximum current-carrying value of a single-phase line is 210A, and there are currently 3 charging piles operating, each allocated 16A of current, then the currently allocated current-carrying capacity is 48A, and the remaining current-carrying value is 210-48=163A. The corresponding data ensures that the line used to calculate the remaining current-carrying value of the current-carrying pool is accurate, avoiding misjudgments caused by line confusion.

[0040] S34, Match the corresponding scheduling rule according to the remaining current carrying capacity of the current carrying pool.

[0041] After confirming that a vehicle has entered parking space A, the intelligent dispatch center immediately formulates a specific dispatch plan based on the remaining current carrying capacity of the current-carrying pool and according to the preset dispatch strategy rules. Considering that charging pile C1 can output a minimum of 3.5kW of power, the dispatch center pre-allocates the current carrying capacity of one charging pile (let's say DU1) to charging pile C1 to ensure that it can obtain sufficient current for charging.

[0042] The scheduling rules include a first scheduling rule and a second scheduling rule. When the remaining current carrying capacity of the current-carrying pool is greater than or equal to a preset current carrying capacity, the scheduling rule is determined to be the first scheduling rule; when the remaining current carrying capacity of the current-carrying pool is equal to 0A, the scheduling rule is determined to be the second scheduling rule. Specifically, (1) First scheduling rule: The remaining current carrying capacity of the current carrying pool is ≥16A.

[0043] The intelligent dispatch center first queries the remaining current carrying capacity of the current carrying capacity pool. When the remaining current carrying capacity is greater than or equal to 16A, it obtains the priority of each parking space and, according to the priority rule (parking spaces occupied for more than 30 minutes and not charged > parking spaces that are vacant), calls the current carrying capacity of one charging pile DU1 (that is, the charging pile corresponding to the highest priority parking space) from the current carrying capacity pool and sets the output power of the DU1 charging pile to 0kW.

[0044] The output power of charging pile C1 in parking space A is set to the sum of the power corresponding to the current remaining current value and the power corresponding to the fixed allocated current (i.e., 16A). To ensure a minimum output power of 3.5kW, if the power corresponding to the current remaining current value is 0kW (i.e., initially unallocated current), after allocating 16A current, the scheduling strategy is to modify the output power of charging pile C1 in parking space A to 3.5kW (corresponding to 16A current; according to P=UI, assuming voltage U=220V, P=220×16÷1000=3.52kW≈3.5kW).

[0045] Meanwhile, the intelligent dispatch center can also set preset conditions to automatically release the output power of charging piles. These preset conditions include one or a combination of the following: the target charging pile has not received a user's charging order for more than a preset time period (e.g., 30 minutes) or a vehicle has been detected leaving the target parking space within that preset time period. Taking into account situations where users may not place charging orders in time or vehicles may leave after a short stop, if a user has not placed a charging order for a car at charging pile A for more than 30 minutes, or if a vehicle leaves within 30 minutes, the intelligent dispatch center will formulate a strategy to automatically release the output power of the charging piles. Specifically, this involves modifying the output power of charging pile C1 to 3.5kW (maintaining a 16A current carrying capacity) and simultaneously modifying the output power of charging pile DU1 to 3.5kW (16A) to rebalance charging resources.

[0046] (2) Second scheduling rule: Remaining current value in the current carrying pool = 0A.

[0047] When the remaining current in the current-carrying pool is 0A, the intelligent dispatch center needs to draw current from the charging piles that have already started charging. At this time, it queries the system for the earliest charging pile DU2 that has started charging and is fully loaded with an output of 7kW (corresponding to 32A current). The dispatch strategy is to suspend charging of charging pile DU2, modify its output power to 3.5kW (16A), and restart charging pile DU2 after the modification is successful; at the same time, the output power of charging pile C1 in parking space A is modified to 3.5kW (16A) to ensure that the vehicle in parking space A can start charging.

[0048] Similarly, the intelligent dispatch center automatically releases the charging pile output power according to preset conditions. For situations where users may not place an order for charging at parking space A, or where vehicles leave after a short stop, if no order is placed for charging at parking space A within 30 minutes, or if a vehicle leaves within 30 minutes, the dispatch center formulates a corresponding strategy. Specifically, the output power of charging pile C1 is retained at 3.5kW (16A), charging at charging pile DU2 is stopped, and the output power of DU2 is changed back to 7kW (32A). After successful modification, charging pile DU2 is restarted to resume charging, thus restoring the original charging resource allocation status.

[0049] S35, generate scheduling instruction data according to the scheduling rules, and send the scheduling instruction data to the target charging pile so that the target charging pile modifies the output power of the charging pile when it receives the scheduling instruction data.

[0050] Once a matching scheduling rule is found, the intelligent scheduling center enters the instruction generation and distribution phase. Specifically, based on the established scheduling rules, the system generates scheduling instruction data using specific algorithms and data processing logic. This scheduling instruction data contains the operation information that the target charging pile needs to perform, such as the adjustment value of the output power. After generating the scheduling instruction data, the system uses the MQTT communication protocol to accurately distribute the scheduling instruction data to the pre-determined target charging piles. Upon receiving the scheduling instruction data, the target charging pile's internal power control module immediately parses the instruction and modifies the charging pile's output power according to the instruction requirements, thereby achieving intelligent scheduling of flexible charging.

[0051] Compared to existing technologies, this application acquires parking space and charging pile data in real time and accurately matches scheduling rules. Based on the remaining current carrying capacity of the charging pool, it rationally allocates current according to priority, ensuring line safety, avoiding overload risks, and improving user charging safety and experience. It can also support doubling the number of charging spaces to meet greater charging demand. Automatic power release based on preset conditions effectively alleviates the problem of non-charging vehicles occupying charging spaces. Flexible adjustment of charging pile output power improves the intelligence and flexibility of the adjustment. Furthermore, setting the charging pool based on the maximum current carrying capacity of a single phase of the station line eliminates the need for complex line modifications, reducing construction costs and thus improving overall profitability.

[0052] Reference Figure 4 The diagram shown is a functional block diagram of a flexible charging scheduling device for car charging piles according to an embodiment of this application.

[0053] In some embodiments, the flexible charging scheduling device 40 for electric vehicle charging piles may include multiple functional modules composed of computer program segments. The computer programs for each program segment of the flexible charging scheduling device 40 may be stored in the memory of an electronic device and executed by at least one processor to perform (see details). Figure 3 (Description) The function of flexible charging scheduling for electric vehicle charging piles. Based on the functions they perform, they can be divided into multiple functional modules.

The module referred to in this application is a series of computer program segments that can be executed by at least one processor and perform a fixed function, stored in memory. In this embodiment, the functions of each module will be detailed in subsequent embodiments.

[0054] The data acquisition module 401 is used to acquire parking space detection data for each parking space distributed by the parking space detector, and charging pile data for each charging pile.

[0055] The correspondence determination module 402 is used to determine the correspondence data between the parking space detector and each charging pile.

[0056] The remaining current carrying capacity determination module 403 is used to determine the remaining current carrying capacity of the current carrying pool corresponding to the target charging pile based on the corresponding relationship data when it is determined from the parking space detection data that there is vehicle entry data in the target parking space; the current carrying pool is a total current capacity pool set according to the maximum single-phase current carrying capacity of the station line; the target parking space is any parking space, and the target charging pile is the charging pile corresponding to the target parking space.

[0057] The scheduling rule matching module 404 is used to match the corresponding scheduling rule according to the remaining current value of the current carrying pool.

[0058] The instruction generation and distribution module 405 is used to generate scheduling instruction data according to the scheduling rules and distribute the scheduling instruction data to the target charging pile, so that the target charging pile can modify its output power when it receives the scheduling instruction data.
