Description

Technical Field

[0001] This invention relates to the field of power information processing technology, and more specifically, to a method and apparatus for controlling the relationship between an electricity information collection terminal and a charging pile. Background Technology

[0002] Electric vehicles (EVs) have rapidly risen to prominence due to their zero emissions, low noise, and high efficiency, becoming a crucial tool for emission reduction in the transportation sector. However, the large-scale adoption of EVs has brought new challenges to the construction of charging infrastructure. Especially during peak electricity consumption periods, the concentrated use of charging stations can lead to a series of problems such as grid overload and voltage fluctuations. Existing control strategies primarily rely on preset power limits and timed polling. Flexible commands lack a closed-loop perception of real-time load in distribution areas, making it impossible to promptly add restrictions when load surges, resulting in consistently slow adjustments. Furthermore, power reduction uses a one-size-fits-all approach, ignoring differences in the adjustment capabilities of individual charging stations, leading to some commands failing to be implemented and wasting adjustable resources. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a method and apparatus for regulating the relationship between an electricity information collection terminal and a charging pile.

[0004] According to one aspect of the present invention, a control method between an electricity information collection terminal and a charging pile is provided, comprising: In response to the user initiating the charging operation, the charging pile intelligent controller or protocol converter generates a charging start event and reports it to the electricity information collection terminal. The charging start event includes at least the charging pile identifier, the starting charging power, and the rated output power. After receiving a charging start event, the electricity information collection terminal will add the corresponding charging pile to the polling list, collect the operating status data of the charging pile according to the preset cycle, and send the operating status data to the main station of the electricity information collection. The main power supply station calculates the load control value that needs to be controlled based on the operating status information of the transformer area, and generates flexible control parameters based on the load control value and sends them to the power consumption information acquisition terminal. The electricity information collection terminal performs differentiated power allocation based on flexible control parameters and the real-time adjustable margin of each charging pile, generates power control commands and sends them to the corresponding charging piles, prioritizing the adjustment of charging piles with larger adjustable margins. In response to the user ending the charging operation, the charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity information collection terminal. After receiving the charging end event, the electricity information collection terminal removes the corresponding charging pile from the polling list and stops periodically polling the charging pile.

[0005] Optionally, in response to the user initiating a charging operation, the charging pile intelligent controller or protocol converter generates a charging start event and reports it to the electricity consumption information collection terminal, including: For charging piles with built-in HPLC / dual-mode communication modules, after the charging pile intelligent controller receives the charging execution command issued by the operator platform, it directly generates a charging start event and reports it to the electricity information collection terminal. For charging piles with external protocol converters, the protocol converter periodically queries the charging pile controller via RS485 or Bluetooth communication. When a new charging start event is detected, the charging start event is reported to the electricity information collection terminal.

[0006] Optionally, the operating status data includes at least one of transformer operating data, charging pile metering data, and charging pile operating data; Transformer operating data includes voltage, current, transformer capacity, and transformer load status; The metering data for charging piles includes voltage, current, energy readings, and frozen data; Charging pile operation data includes charging status and charging events.

[0007] Optionally, the main data acquisition station calculates the load control values ​​that need to be adjusted based on the operating status information of the distribution area, including: The historical data of adjustable resources of charging piles in the distribution area are analyzed by the main monitoring station to evaluate the adjustable load capacity of each charging pile. Based on the adjustable load capacity, the load reduction index is decomposed and flexible control parameters are generated. The flexible control parameters are sent to the electricity consumption information collection terminal.

[0008] Optionally, the electricity information collection terminal, based on flexible control parameters and the real-time adjustable margin of each charging pile, performs differentiated power allocation and generates power control commands to be sent to the corresponding charging piles, including: The electricity information collection terminal determines whether the current period is a planned scheduling period or a real-time scheduling period based on the flexible control parameters. If it is a planned scheduling period, prepare the control instructions to the charging piles in advance to ensure that the resources respond on time; If it is a real-time scheduling period, the maximum allowable output power of each charging pile will be dynamically adjusted based on the operating status data obtained by periodic polling. If the actual load approaches the safety threshold but the scheduled scheduling time has not yet arrived, real-time scheduling will be initiated immediately. Optionally, it also includes: When the total load of the distribution area is higher than the set threshold and all charging piles that support flexible adjustment have been adjusted to the minimum power, it is still impossible to ensure the safe operation of the power grid. Rigid control is implemented for charging piles that do not support flexible adjustment commands or cannot respond to power adjustment commands. The rigid control mentioned above includes cutting off the power supply to the charging pile by switching the power supply line with the meter switch or external circuit breaker.

[0009] Optionally, the power regulation command's regulation process also includes: During the control process, when a new charging gun is detected to be connected and the charging status is "charging", a delay is made to wait for the new charging gun to reach full load operation. After the delay ends, the load distribution of all charging guns is recalculated, and new power control commands are generated to ensure that the load of newly connected charging piles is balanced with that of existing charging piles.

[0010] Optionally, in response to the user ending the charging operation, the charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity consumption information collection terminal, including: For charging piles with built-in HPLC / dual-mode communication modules, the charging pile intelligent controller directly generates a charging end event and reports it to the electricity information collection terminal. For charging piles with external protocol converters, the protocol converter periodically queries the charging pile controller. When a new charging end event is detected, the charging end event is reported to the electricity information collection terminal. A charging completion event should include at least the charging station identifier, charging start time, charging end time, and reason for charging completion. If the charging completion event reporting fails, the reporting will be retried at the preset interval.

[0011] According to another aspect of the present invention, a control device is provided between an electricity information collection terminal and a charging pile, comprising: The reporting module is used to respond to the user's charging operation. The charging pile smart controller or protocol converter generates a charging start event and reports it to the electricity information collection terminal. The charging start event includes at least the charging pile identifier, the starting charging power, and the rated output power. The upload module is used to include the corresponding charging pile in the polling list after the electricity information collection terminal receives the charging start event, collect the operating status data of the charging pile according to the preset period, and upload the operating status data to the main station of the electricity information collection. The calculation module is used by the main power supply station to calculate the load control value that needs to be controlled based on the operating status information of the transformer area, and to generate flexible control parameters based on the load control value and send them to the power consumption information acquisition terminal. The first generation module is used by the electricity information collection terminal to perform differentiated power allocation based on the flexible control parameters and the real-time adjustable margin of each charging pile, generate power control commands and send them to the corresponding charging piles, and prioritize the adjustment of charging piles with larger adjustable margins. The second generation module is used to respond to the user's end of the charging operation. The charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity information collection terminal. After receiving the charging end event, the electricity information collection terminal removes the corresponding charging pile from the polling list and stops periodic polling.

[0012] According to another aspect of the present invention, a computer-readable storage medium is provided, the storage medium storing a computer program for performing the methods described in any of the above aspects of the present invention.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising: a processor; a memory for storing executable instructions of the processor; the processor being configured to read the executable instructions from the memory and execute the instructions to implement the method described in any of the preceding aspects of the present invention.

[0014] Therefore, this invention, through the power consumption information collection terminal receiving control instructions and indicators from the power consumption collection master station, dynamically adjusts the charging power and optimizes resource allocation by analyzing the charging pile operation data under the transformer area in real time, thereby reducing the grid load pressure caused by the operation of charging piles, realizing dynamic optimization of load allocation, and thus effectively alleviating the pressure on the power grid.

[0029] Exemplary methods Figure 1 This is a schematic flowchart illustrating a control method between an electricity information collection terminal and a charging pile, provided in an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as… Figure 1 As shown, the control method 100 between the electricity information collection terminal and the charging pile includes the following steps: Step 101: In response to the user initiating the charging operation, the charging pile intelligent controller or protocol converter generates a charging start event and reports it to the electricity information collection terminal. The charging start event includes at least the charging pile identifier, the starting charging power, and the rated output power. Step 102: After receiving the charging start event, the electricity information collection terminal will add the corresponding charging pile to the polling list, collect the operating status data of the charging pile according to the preset cycle, and send the operating status data to the main station of the electricity information collection. Step 103: The main station calculates the load control value that needs to be controlled based on the operating status information of the transformer area, and generates flexible control parameters based on the load control value and sends them to the power consumption information acquisition terminal. Step 104: The electricity information collection terminal performs differentiated power allocation based on the flexible control parameters and the real-time adjustable margin of each charging pile, generates power control instructions and sends them to the corresponding charging piles, giving priority to adjusting the charging piles with larger adjustable margins. Step 105: In response to the user ending the charging operation, the charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity information collection terminal. After receiving the charging end event, the electricity information collection terminal removes the corresponding charging pile from the polling list and stops periodic polling.

[0030] Specifically, in response to the technical problems existing in the prior art, this invention proposes a flexible control method based on the direct connection between the electricity consumption information collection terminal and the charging pile. This method involves the electricity consumption information collection terminal receiving control instructions and indicators from the main power station, and then dynamically adjusting the charging power and optimizing resource allocation by analyzing the operating data of the charging piles under the distribution area in real time. This reduces the load pressure on the power grid caused by the operation of the charging piles, achieves dynamic optimization of load allocation, and effectively alleviates the pressure on the power grid.

[0031] refer to Figure 2 As shown, the specific implementation steps are as follows: A. Users first operate the service through a smartphone application (APP). Specifically, they use the APP's scanning function to scan the QR code on the charging station. After the QR code is successfully scanned, the user clicks the "Start Charging" button on the APP interface. At this point, the APP will formally submit the user's detailed charging needs, including the charging station number and user information, to the charging operator's management platform for subsequent charging service arrangements and monitoring.

[0032] B. Charging Execution: After receiving the user's charging request, the operator platform sends a charging execution command to the charging pile intelligent controller. The charging pile intelligent controller then executes the charging according to the request. For charging piles with built-in HPLC / dual-mode modules, after receiving the charging execution command from the platform, the charging pile intelligent controller generates a charging start event based on the charging request and other information, and reports it to the electricity information collection terminal. For charging piles with external protocol converters, the protocol converter periodically queries (using RS485 / Bluetooth communication) the charging pile controller to check for any new charging start events. Upon detecting a new event, it reports the event to the electricity information collection terminal.

[0033] C. Status monitoring: After receiving the charging start event of the charging pile, the power consumption information collection terminal periodically polls the operating status of the charging pile and promptly sends the data information to the power consumption collection master station. The power consumption collection master station then pushes the relevant information to the operator platform.

[0034] D. The main power station calculates the load value that needs to be regulated for the transformer area based on the operating status information of the transformer area. Then, it sends flexible regulation parameters to the power consumption information acquisition terminal based on the load value. The power consumption information acquisition terminal dynamically regulates the power of the charging piles in real time according to the regulation parameters. When the load of the transformer area is close to the threshold, the acquisition terminal performs differentiated power allocation based on the real-time adjustable margin of each charging pile, giving priority to adjusting the piles with strong response capabilities to avoid resource waste caused by "one-size-fits-all". During periods of severe load fluctuation, the command output is continuously optimized through high-frequency feedback closed loop to ensure accurate and timely regulation.

[0035] E. Charging End: After the user ends charging, the charging pile intelligent controller generates a corresponding charging end event based on the charging information. For charging piles with a built-in HPLC / dual-mode communication module, the charging pile intelligent controller directly reports the charging end event to the electricity information collection terminal. For charging piles with an external protocol converter, the protocol converter periodically queries (using RS485 / Bluetooth communication) the charging pile controller to see if there are any new charging end events. After detecting a new event, it reports the event to the electricity information collection terminal. After receiving the charging end event, the electricity information collection terminal pushes the event to the electricity information collection master station and ends the periodic polling of the charging pile operation information.

[0036] In step B, after the electric vehicle user starts charging, the protocol converter monitors the working status of the charging pile and actively reports a "charging start event" to the fusion terminal. The charging start event includes information such as: charging pile asset number, charging gun number, charging pile adjustment type, starting charging power, rated output power, and expected vehicle usage time.

[0037] In step C, the operating status of the charging pile is periodically polled. The operating status information mainly includes distribution transformer operating data, charging pile metering data, and charging pile operation data. Distribution transformer operating data includes voltage, current, transformer capacity, transformer load status, etc.; charging pile metering data includes voltage, current, energy readings, frozen data, etc.; and charging pile operation data includes charging status, charging events, etc.

[0038] In step D, according to the control method, it can be divided into two categories: planned scheduling and real-time scheduling, such as... Figure 3 As shown.

[0039] D.1 The planned scheduling should prioritize charging during off-peak hours. If the predicted capacity is sufficient, full-power scheduling should be arranged. If the predicted capacity is insufficient, load reduction scheduling should be arranged while ensuring user charging needs. If the predicted off-peak hours cannot meet the charging demand (including capacity and usage time), the gap should be filled as early as possible during peak hours.

[0040] D.2 Real-time scheduling provides immediate response. If the monitoring capacity of the integrated terminal is insufficient, the charging power is equally distributed and can be reduced to the minimum power. When the monitoring capacity is sufficient, the charging power is increased to the rated power. If the monitoring capacity is severely insufficient, the charging power is reduced to the minimum power. If the safe operation of the power grid cannot be guaranteed, a rigid control method is used to sequentially cut off the later charging loads. When the monitoring capacity is sufficient, the earlier charging loads are restored.

[0041] D.3 Rigid control refers to directly cutting off power to the charging piles by switching off the power supply line via a meter switch or external circuit breaker. Rigid control is generally not implemented when the total load of the distribution area is below the set threshold.

[0042] D.4 When the total load of the distribution area is higher than the set threshold of the distribution area load, if the flexible adjustment quota in the distribution area has not been fully used up (all charging piles that support flexible adjustment have not been adjusted), rigid control will not be implemented in principle; if the flexible adjustment quota in the distribution area has been fully used up (all charging piles that support flexible adjustment have been flexibly adjusted), then rigid control will be implemented for charging piles that do not support flexible adjustment commands and cannot respond to power adjustment commands.

[0043] In step E, after charging is complete, the protocol converter proactively reports a "charging completion event" to the converged terminal. This event includes: charging pile asset number, charging gun number, charging start time, charging end time, and the reason for charging completion (normal completion). If a fault occurs during charging and charging cannot continue, the protocol converter proactively reports a "charging completion event" to the converged terminal, with the fault as the reason for charging completion. If the reporting of the above event fails, it will be retried after a 5-minute interval.

[0044] In a specific embodiment of the present invention, the specific implementation steps are as follows: A. Users first operate the service through a smartphone application (APP). Specifically, they use the APP's scanning function to scan the QR code on the charging station. After the QR code is successfully scanned, the user clicks the "Start Charging" button on the APP interface. At this point, the APP will formally submit the user's detailed charging needs, including the charging station number and user information, to the charging operator's management platform for subsequent charging service arrangements and monitoring.

[0045] B. Charging Execution: After receiving the user's charging request, the operator platform sends a charging execution command to the charging pile intelligent controller. The charging pile intelligent controller then executes the charging according to the request. For charging piles with built-in HPLC / dual-mode modules, after receiving the charging execution command from the platform, the charging pile intelligent controller generates a charging start event based on the charging request and other information, and reports it to the electricity information collection terminal. For charging piles with external protocol converters, the protocol converter periodically queries (using RS485 / Bluetooth communication) the charging pile controller to check for any new charging start events. Upon detecting a new event, it reports the event to the electricity information collection terminal.

[0046] C. Status monitoring: After receiving the charging start event of the charging pile, the power consumption information collection terminal periodically polls the operating status of the charging pile and promptly sends the data information to the power consumption collection master station. The power consumption collection master station then pushes the relevant information to the operator platform.

[0047] C.1 Periodic polling is a process where the electricity information collection terminal obtains a list of charging piles that are currently charging based on the charging start and stop events actively reported by the charging piles. According to a set period, it polls the "voltage", "current" and "charging percentage" data of the charging piles to provide a basis for subsequent dynamic and flexible adjustment. If the polling fails for two consecutive periods, the charging pile is determined to be offline.

[0048] D. The main power station calculates the load value that needs to be regulated for the transformer area based on the operating status information of the transformer area. Then, it sends flexible regulation parameters to the power consumption information acquisition terminal based on the load value. The power consumption information acquisition terminal dynamically regulates the power of the charging piles in real time according to the regulation parameters. When the load of the transformer area is close to the threshold, the acquisition terminal performs differentiated power allocation based on the real-time adjustable margin of each charging pile, giving priority to adjusting the piles with strong response capabilities to avoid resource waste caused by "one-size-fits-all". During periods of severe load fluctuation, the command output is continuously optimized through high-frequency feedback closed loop to ensure accurate and timely regulation.

[0049] D.1 The electricity information collection master station analyzes the historical monitoring data of adjustable resources of charging piles in the transformer area, takes into account the adjustable load capacity of each resource, and decomposes the load reduction indicators and control strategies to the electricity information collection terminal.

[0050] D.2 If it is a planned dispatch, the electricity information collection terminal will first determine whether it is within the dispatch period based on the control parameters. If it is within the planned dispatch period, it will issue a preparation control instruction to the charging pile in advance to ensure that the resources respond on time. If it is not within the dispatch period, it will enter standby mode and continuously monitor the load changes in the distribution area. When the actual load approaches the safety threshold, even if it is not the planned dispatch time, the collection terminal will immediately start real-time dispatch.

[0051] In D.3 During the planned scheduling, after the electricity information collection terminal sends the scheduling instruction to the corresponding charging pile, the charging pile intelligent controller adjusts the output power according to the instruction and operates in a lower power mode. When the off-peak period arrives, it gradually restores to the normal charging power to achieve the goal of peak shaving and valley filling.

[0052] D.4 If it is real-time dispatch, the electricity information collection terminal will read the real-time data of the charging piles obtained by the terminal periodically polling, and combine the load capacity of the distribution transformer in the area and the electricity charging situation to dynamically adjust the maximum allowable output power of each charging pile as needed, dynamically generate control instructions and send them to the corresponding charging piles; if it is not during the real-time dispatch period, it will continuously monitor load changes.

[0053] D.5 During the effective control period, the electricity information collection terminal will continuously monitor the real-time load changes of the charging piles. When a change in the charging status of the charging gun is detected, the terminal will immediately recalculate and adjust the output power to ensure reasonable load distribution and prevent overload risks. At the same time, the system records all control data for subsequent analysis and optimization strategies.

[0054] D.6 For newly added charging guns during the control process, when the monitoring shows that the charging status is "charging" or the charging stage is "not charging", the terminal will delay for 1 to 2 minutes to wait for the charging gun to reach full load operation, and then recalculate the load distribution and output power of all charging guns to ensure that the newly added charging piles are balanced with the existing equipment load.

[0055] E. Charging End: After the user ends charging, the charging pile intelligent controller generates a corresponding charging end event based on the charging information. For charging piles with a built-in HPLC / dual-mode communication module, the charging pile intelligent controller directly reports the charging end event to the electricity information collection terminal. For charging piles with an external protocol converter, the protocol converter periodically queries (using RS485 / Bluetooth communication) the charging pile controller to see if there are any new charging end events. After detecting a new event, it reports the event to the electricity information collection terminal and ends the periodic polling of the charging pile operation information.

[0056] Therefore, this invention proposes an intelligent management method that coordinates load regulation with charging piles. This method significantly improves the precision of load regulation of charging piles in the distribution area. The core of this technology is that the main power acquisition station calculates the load value that needs to be regulated in the distribution area according to the load regulation requirements, and realizes flexible power adjustment of charging piles through the power information acquisition terminal. The power information acquisition terminal performs differentiated regulation based on the real-time adjustable margin of each charging pile, giving priority to adjusting piles with fast response speed and large power adjustment range, thereby achieving precise load allocation.

[0057] Exemplary device Figure 4This is a schematic diagram of the control device between the electricity information collection terminal and the charging pile provided in an exemplary embodiment of the present invention. Figure 4 As shown, the device 400 includes: The reporting module 410 is used to respond to the user's charging operation. The charging pile intelligent controller or protocol converter generates a charging start event and reports it to the electricity information collection terminal. The charging start event includes at least the charging pile identifier, the starting charging power, and the rated output power. The uploading module 420 is used to include the corresponding charging pile in the polling list after the electricity information collection terminal receives the charging start event, to collect the operating status data of the charging pile according to the preset period, and to upload the operating status data to the main station of the electricity information collection. The calculation module 430 is used by the main station to calculate the load control value that needs to be controlled based on the operating status information of the transformer area, and to generate flexible control parameters based on the load control value and send them to the power consumption information acquisition terminal. The first generation module 440 is used by the electricity information collection terminal to perform differentiated power allocation based on the flexible control parameters and the real-time adjustable margin of each charging pile, generate power control commands and send them to the corresponding charging piles, and prioritize the adjustment of charging piles with larger adjustable margins. The second generation module 450 is used to respond to the user's end of the charging operation. The charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity information collection terminal. After receiving the charging end event, the electricity information collection terminal removes the corresponding charging pile from the polling list and stops periodic polling.

[0058] Optionally, the reporting module 410 includes: For charging piles with built-in HPLC / dual-mode communication modules, after the charging pile intelligent controller receives the charging execution command issued by the operator platform, it directly generates a charging start event and reports it to the electricity information collection terminal.

[0060] Optionally, the calculation module 430 uses the master station to calculate the load control value to be adjusted based on the operating status information of the transformer area, including: The historical data of adjustable resources of charging piles in the distribution area are analyzed by the main monitoring station to evaluate the adjustable load capacity of each charging pile. Based on the adjustable load capacity, the load reduction index is decomposed and flexible control parameters are generated. The flexible control parameters are sent to the electricity consumption information collection terminal.

[0061] Optionally, the electricity information collection terminal, based on flexible control parameters and the real-time adjustable margin of each charging pile, performs differentiated power allocation and generates power control commands to be sent to the corresponding charging piles, including: The electricity information collection terminal determines whether the current period is a planned scheduling period or a real-time scheduling period based on the flexible control parameters. If it is a planned scheduling period, prepare the control instructions to the charging piles in advance to ensure that the resources respond on time; If it is a real-time scheduling period, the maximum allowable output power of each charging pile will be dynamically adjusted based on the operating status data obtained by periodic polling. If the actual load approaches the safety threshold but the scheduled scheduling time has not yet arrived, real-time scheduling will be initiated immediately. Optionally, it also includes: When the total load of the distribution area is higher than the set threshold and all charging piles that support flexible adjustment have been adjusted to the minimum power, it is still impossible to ensure the safe operation of the power grid. Rigid control is implemented for charging piles that do not support flexible adjustment commands or cannot respond to power adjustment commands. The rigid control mentioned above includes cutting off the power supply to the charging pile by switching the power supply line with the meter switch or external circuit breaker.

[0062] Optionally, the power regulation command's regulation process also includes: During the control process, when a new charging gun is detected to be connected and the charging status is "charging", a delay is made to wait for the new charging gun to reach full load operation. After the delay ends, the load distribution of all charging guns is recalculated, and new power control commands are generated to ensure that the load of newly connected charging piles is balanced with that of existing charging piles.

[0063] Optionally, in response to the user ending the charging operation, the charging pile intelligent controller or protocol converter generates a charging end event and reports it to the electricity consumption information collection terminal, including: For charging piles with built-in HPLC / dual-mode communication modules, the charging pile intelligent controller directly generates a charging end event and reports it to the electricity information collection terminal. For charging piles with external protocol converters, the protocol converter periodically queries the charging pile controller. When a new charging end event is detected, the charging end event is reported to the electricity information collection terminal.
