Description

[0001] This case is a divisional application based on the invention patent with application date of September 5, 2023, application number 202311139269.3, and name “A low-power operation method and terminal for a charging pile” as the parent case. Technical Field

[0002] The present invention relates to the technical field of charging piles, and in particular to a method and a terminal for reducing the operating energy consumption of a charging pile. Background Art

[0003] Globally, with growing environmental awareness and the push for energy transition, the development of electric vehicles (EVs) has become an irreversible trend. To meet the charging needs of EVs, the construction of charging stations is expanding. The multifunctionality of charging stations—meaning they not only meet charging needs but also offer additional services such as wireless internet access, leisure and entertainment, and information query—has led to their widespread use in daily life.

[0004] However, there's a problem with the actual use of multifunctional charging piles. Because charging piles need to provide multiple auxiliary power functions while charging electric vehicles, such as wireless network access, light strip indicators, and camera recognition, they consume more auxiliary power during use. This phenomenon reduces the overall system conversion efficiency, thereby affecting the energy efficiency of the charging station. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method and a terminal for reducing the operating energy consumption of a charging pile, thereby effectively saving the power consumption of the charging pile.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A method for reducing the energy consumption of a charging pile comprises the following steps:

[0008] S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed.

[0009] S2. The charging main control board detects whether the plug-in signal of the charging gun changes at a preset time. If no change occurs, the charging pile is controlled to enter the sleep mode;

[0010] S3, after the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, the charging pile is controlled to exit the sleep mode and enter normal operation;

[0011] S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on the day;

[0012] The step S2 is specifically as follows:

[0013] The charging main control board detects the plug-in signal of the charging gun at preset intervals. If the plug-in signal does not change within the preset time, the charging pile is controlled to enter a sleep mode, and a sleep instruction is sent to each module in the charging pile to control each module to stop working, and only the identification and judgment of the plug-in signal on the charging gun is retained;

[0014] The step S2 further includes:

[0015] The charging main control board controls the EMS system to identify holidays. If information identifying holidays is obtained from the EMS system, the dormancy function of the charging pile is turned off.

[0016] The step S4 is specifically as follows:

[0017] S41. The charging pile control board repeats steps S1 to S3 above, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when the charging pile enters the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5, and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the gun plug signal before entering the sleep mode on the next day as T3;

[0018] S42, calculating the actual dormancy failure rate K' = (C1-C2) / C1 on that day;

[0019] S43. If the actual sleep failure rate K'>K on that day, it means that there were multiple short charging intervals that resulted in sleep failure on that day, and the process goes to step S44. Otherwise, set T3=T1-T5;

[0020] S44. If (T1+T5) is greater than (T2+T4), set T3=T1+T5; otherwise, set T3=T2+T5.

[0021] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0022] A terminal for reducing the energy consumption of a charging pile includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When executing the computer program, the processor implements the following steps:

[0023] S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed.

[0024] S2. The charging main control board detects whether the plug-in signal of the charging gun changes at a preset time. If no change occurs, the charging pile is controlled to enter the sleep mode;

[0025] S3, after the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, the charging pile is controlled to exit the sleep mode and enter normal operation;

[0026] S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on the day;

[0027] The step S2 is specifically as follows:

[0028] The charging main control board detects the plug-in signal of the charging gun at preset intervals. If the plug-in signal does not change within the preset time, the charging pile is controlled to enter a sleep mode, and a sleep instruction is sent to each module in the charging pile to control each module to stop working, and only the identification and judgment of the plug-in signal on the charging gun is retained;

[0029] The step S2 further includes:

[0030] The charging main control board identifies holidays and, if holiday information is identified, controls the dormancy function of the charging pile to be turned off;

[0031] The step S4 is specifically as follows:

[0032] S41. The charging pile control board repeats steps S1 to S3 above, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when the charging pile enters the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5, and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the gun plug signal before entering the sleep mode on the next day as T3;

[0033] S42, calculating the actual dormancy failure rate K' = (C1-C2) / C1 on that day;

[0034] S43. If the actual sleep failure rate K'>K on that day, it means that there were multiple short charging intervals that resulted in sleep failure on that day, and the process goes to step S44. Otherwise, set T3=T1-T5;

[0035] S44. If (T1+T5) is greater than (T2+T4), set T3=T1+T5; otherwise, set T3=T2+T5.

[0036] The beneficial effects of the present invention are: the communication status with each module of the charging pile is detected in real time by the charging main control board, and whether the charging pile is available is judged according to whether the communication is abnormal, and then whether the charging pile needs to enter the low power consumption mode to save power consumption; at the same time, if there is no abnormality in the communication, the charging main control board detects whether the CC1 gun plug signal of the charging gun changes at preset time intervals, so that when the CC1 gun plug signal does not change for a period of time, it is judged that the charging gun in the charging pile is not connected to the electric car at this time. Therefore, in order to further save power consumption, the charging pile is controlled to enter the sleep mode; in addition, in order to ensure the intelligent adjustment of the timing of the charging pile entering the sleep mode, the preset time used for the sleep mode judgment on the next day is calculated through the charging, sleep and other data of each day, so as to realize the intelligent adjustment of the time when the charging pile enters the sleep mode, improve the intelligent design of the charging pile, and further reduce the energy loss of the charging pile. At the same time, the charging main control board can directly determine whether the charging gun is connected to the electric vehicle for charging operations based on whether the gun plug-in signal of the charging gun changes within a certain preset time; when the gun plug-in signal does not change within the preset time, the charging pile enters sleep mode, and the modules in the charging pile can be powered off and stop running, thereby greatly ensuring low energy consumption. At the same time, in order to ensure that the charging pile can start and work quickly during subsequent plug-in charging operations, the charging main control board needs to continue to identify and judge the gun plug-in signal on the charging gun to ensure timely response to the resumption of charging operations; in addition, since the number of charging orders for charging piles will increase sharply during holidays, in order to reduce the waiting time for car owners to start charging, the charging main control board adds a holiday recognition function. When a holiday is recognized, the sleep function of the charging pile is completely turned off, maintaining an efficient normal charging mode for car owners throughout the day.

[0043] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0044] Please refer to Figures 1 to 3 A method for reducing the energy consumption of a charging pile comprises the following steps:

[0045] S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed.

[0046] S2. The charging main control board detects whether the plug-in signal of the charging gun changes at a preset time. If no change occurs, the charging pile is controlled to enter the sleep mode;

[0047] S3, after the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, the charging pile is controlled to exit the sleep mode and enter normal operation;

[0048] S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on the day;

[0049] The step S2 is specifically as follows:

[0050] The charging main control board detects the plug-in signal of the charging gun at preset intervals. If the plug-in signal does not change within the preset time, the charging pile is controlled to enter a sleep mode, and a sleep instruction is sent to each module in the charging pile to control each module to stop working, and only the identification and judgment of the plug-in signal on the charging gun is retained;

[0051] The step S2 further includes:

[0052] The charging main control board controls the EMS system to identify holidays. If information identifying holidays is obtained from the EMS system, the dormancy function of the charging pile is turned off.

[0053] The step S4 is specifically as follows:

[0054] S41. The charging pile control board repeats steps S1 to S3 above, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when the charging pile enters the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5, and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the gun plug signal before entering the sleep mode on the next day as T3;

[0055] S42, calculating the actual dormancy failure rate K' = (C1-C2) / C1 on that day;

[0056] S43. If the actual sleep failure rate K'>K on that day, it means that there were multiple short charging intervals that resulted in sleep failure on that day, and the process goes to step S44. Otherwise, set T3=T1-T5;

[0057] S44. If (T1+T5) is greater than (T2+T4), set T3=T1+T5; otherwise, set T3=T2+T5.

[0058] From the above description, it can be seen that the beneficial effects of the present invention are: the communication status with each module of the charging pile is detected in real time by the charging main control board, and whether the charging pile is available is judged according to whether the communication is abnormal, and then whether the charging pile needs to enter low power consumption mode to save power consumption; at the same time, if there is no abnormality in the communication, the charging main control board detects whether the CC1 gun plug signal of the charging gun changes at preset time intervals, so that when the CC1 gun plug signal does not change for a period of time, it is judged that the charging gun in the charging pile is not connected to the electric car at this time. Therefore, in order to further save power consumption, the charging pile is controlled to enter sleep mode; in addition, in order to ensure the intelligent adjustment of the timing of the charging pile entering sleep mode, the preset time for the next day to be used for sleep mode judgment is calculated through the charging, sleep and other data of each day, so as to realize the intelligent adjustment of the time when the charging pile enters sleep, improve the intelligent design of the charging pile, and further reduce the energy loss of the charging pile. At the same time, the charging main control board can directly determine whether the charging gun is connected to the electric vehicle for charging operations based on whether the gun plug-in signal of the charging gun changes within a certain preset time; when the gun plug-in signal does not change within the preset time, the charging pile enters sleep mode, and the modules in the charging pile can be powered off and stop running, thereby greatly ensuring low energy consumption. At the same time, in order to ensure that the charging pile can start and work quickly during subsequent plug-in charging operations, the charging main control board needs to continue to identify and judge the gun plug-in signal on the charging gun to ensure timely response to the resumption of charging operations; in addition, since the number of orders for charging piles will increase sharply during holidays, in order to reduce the waiting time for car owners to start charging, the charging main control board adds a holiday recognition function. When a holiday is recognized, the sleep function of the charging pile is completely turned off, maintaining an efficient normal charging mode for car owners throughout the day.

[0059] Furthermore, the step S1 is specifically as follows:

[0060] The charging main control board detects the communication status of each module in the charging pile in real time. When there is a communication anomaly with at least one module, the charging pile is controlled to enter low power mode, stop charging, and disconnect the communication connection with other modules except the module with communication anomaly until the module with communication anomaly resumes communication normally.

[0061] The modules in the charging pile include IO detection module, light strip control module, camera control module, insulation detection module and DC meter.

[0062] From the above description, it can be seen that the charging pile is an overall working system. When the communication of a module in the charging pile system is abnormal, it means that the charging pile is unavailable, so the charging pile needs to be powered off and charging needs to be stopped. At the same time, the communication connection between each module in the charging pile and the charging main control board is disconnected, and only the communication connection with abnormal communication is retained. In this way, when the module with abnormal communication resumes normal communication while ensuring low energy consumption, the charging pile can be quickly started to resume normal charging work.

[0063] Please refer to Figure 4 A terminal for reducing the energy consumption of a charging pile includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When executing the computer program, the processor implements the following steps:

[0064] S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed.

[0065] S2. The charging main control board detects whether the plug-in signal of the charging gun changes at a preset time. If no change occurs, the charging pile is controlled to enter the sleep mode;

[0066] S3, after the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, the charging pile is controlled to exit the sleep mode and enter normal operation;

[0067] S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on the day;

[0068] The step S2 is specifically as follows:

[0069] The charging main control board detects the plug-in signal of the charging gun at preset intervals. If the plug-in signal does not change within the preset time, the charging pile is controlled to enter a sleep mode, and a sleep instruction is sent to each module in the charging pile to control each module to stop working, and only the identification and judgment of the plug-in signal on the charging gun is retained;

[0070] The step S2 further includes:

[0071] The charging main control board identifies holidays and, if holiday information is identified, controls the dormancy function of the charging pile to be turned off;

[0072] The step S4 is specifically as follows:

[0073] S41. The charging pile control board repeats steps S1 to S3 above, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when the charging pile enters the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5, and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the gun plug signal before entering the sleep mode on the next day as T3;

[0074] S42, calculating the actual dormancy failure rate K' = (C1-C2) / C1 on that day;

[0075] S43. If the actual sleep failure rate K'>K on that day, it means that there were multiple short charging intervals that resulted in sleep failure on that day, and the process goes to step S44. Otherwise, set T3=T1-T5;

[0076] S44. If (T1+T5) is greater than (T2+T4), set T3=T1+T5; otherwise, set T3=T2+T5.

[0077] From the above description, it can be seen that the beneficial effects of the present invention are: based on the same technical concept, in conjunction with the above-mentioned method for reducing the operating energy consumption of a charging pile, a terminal for reducing the operating energy consumption of a charging pile is provided, and the communication status with each module of the charging pile is detected in real time by the charging main control board, and whether the charging pile is available is judged according to whether the communication is abnormal, and then whether the charging pile needs to enter a low power consumption mode to save power consumption; at the same time, if there is no abnormality in the communication, the charging main control board detects whether the CC1 plug-in signal of the charging gun changes at preset time intervals, so that when the CC1 plug-in signal does not change for a period of time, it is judged that the charging gun in the charging pile is not connected to the electric vehicle at this time, so in order to further save power consumption, the charging pile is controlled to enter sleep mode; in addition, in order to ensure the intelligent adjustment of the timing of the charging pile entering sleep mode, the preset time for the sleep mode judgment of the next day is calculated through the charging, sleep and other data of each day, so as to realize the intelligent adjustment of the time when the charging pile enters sleep, improve the intelligent design of the charging pile, and further reduce the energy loss of the charging pile. At the same time, the charging main control board can directly determine whether the charging gun is connected to the electric vehicle for charging operations based on whether the gun plug-in signal of the charging gun changes within a certain preset time; when the gun plug-in signal does not change within the preset time, the charging pile enters sleep mode, and the modules in the charging pile can be powered off and stop running, thereby greatly ensuring low energy consumption. At the same time, in order to ensure that the charging pile can start and work quickly during subsequent plug-in charging operations, the charging main control board needs to continue to identify and judge the gun plug-in signal on the charging gun to ensure timely response to the resumption of charging operations; in addition, since the number of charging orders for charging piles will increase sharply during holidays, in order to reduce the waiting time for car owners to start charging, the charging main control board adds a holiday recognition function. When a holiday is recognized, the sleep function of the charging pile is completely turned off, maintaining an efficient normal charging mode for car owners throughout the day.

[0078] Furthermore, the step S1 is specifically as follows:

[0079] The charging main control board detects the communication status of each module in the charging pile in real time. When there is a communication anomaly with at least one module, the charging pile is controlled to enter low power mode, stop charging, and disconnect the communication connection with other modules except the module with communication anomaly until the module with communication anomaly resumes communication normally.

[0080] The modules in the charging pile include IO detection module, light strip control module, camera control module, insulation detection module and DC meter.

[0081] From the above description, it can be seen that the charging pile is an overall working system. When the communication of a module in the charging pile system is abnormal, it means that the charging pile is unavailable, so the charging pile needs to be powered off and charging needs to be stopped. At the same time, the communication connection between each module in the charging pile and the charging main control board is disconnected, and only the communication connection with abnormal communication is retained. In this way, when the module with abnormal communication resumes normal communication while ensuring low energy consumption, the charging pile can be quickly started to resume normal charging work.

[0082] The present inventors provide a method and terminal for reducing the energy consumption of a charging pile, which is applicable to various charging pile charging scenarios. Detailed description will be given below with reference to the following embodiments.

[0083] Please refer to Figure 1 and Figure 2 , embodiment 1 of the present invention is:

[0084] A method to reduce the energy consumption of charging pile operation, such as Figure 1 As shown, the steps include:

[0085] S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed.

[0086] Wherein, step S1 is specifically as follows:

[0087] The charging main control board can detect the communication status with each module in the charging pile in real time through the EMS system. When there is a communication abnormality with at least one module, a low-power instruction is sent to the charging pile through the EMS system to control the charging pile to enter low-power mode, stop charging, and disconnect the communication connection with other modules except the module with communication abnormality until the module with communication abnormality resumes normal communication.

[0088] like Figure 2 The figure shows a communication principle diagram of a method for reducing the energy consumption of a charging pile according to an embodiment of the present invention. Figure 2 It can be seen that the modules in the charging pile include an IO detection module, a light strip control module, a camera control module, an insulation detection module and a DC meter. In other equivalent embodiments, the modules may not be limited to Figure 2 As shown in the figure; at the same time, in this embodiment, the charging main control board and the modules in the charging pile can communicate and interact through communication protocols such as CAN, RS485, Bluetooth or WIFI to achieve two-way data transmission, complete charging pile status indication, command issuance, electric vehicle license plate recognition and recording, and electric vehicle charging control, etc., which are not limited here.

[0089] S2. The charging main control board detects whether the plug-in signal of the charging gun changes at preset intervals. If there is no change, the charging pile is controlled to enter the sleep mode.

[0090] Step S2 is specifically as follows:

[0091] The charging main control board detects the plug-in signal of the charging gun (i.e. the CC1 pin level signal on the charging gun) through the EMS system at preset time intervals. When the plug-in signal does not change within the preset time, the EMS system sends a sleep command to the charging pile to control the charging pile to enter sleep mode. At the same time, a sleep command is sent to each module in the charging pile to control each module to stop working, and only the recognition and judgment of the plug-in signal on the charging gun is retained.

[0092] That is, in this embodiment, the charging main control board can directly determine whether the charging gun is connected to the electric vehicle for charging operation based on whether the gun plug-in signal of the charging gun changes within a certain preset time; and when the gun plug-in signal does not change within the preset time, the charging pile enters the sleep mode, and the various modules in the charging pile can be powered off and stop running, thereby greatly ensuring low energy consumption. At the same time, in order for the charging pile to be able to start and work quickly when the gun is plugged in and charging is performed subsequently, the charging main control board needs to continue to recognize and judge the gun plug-in signal on the charging gun to ensure timely response to the resumption of charging operation.

[0093] Among them, in addition to the conventional functional modules, the charging pile in this embodiment also adds a light strip display function and a camera function compared to the existing common charging pile system, that is, Figure 2 The light strip controller and camera controller shown in the figure, wherein the light strip controller can control the light strip to turn off after receiving the sleep command, and the camera controller can control the camera to stop taking pictures and the fill light to stop working after receiving the sleep command, so as to turn off the power consumption of non-essential devices during the idle period when the charging pile is not charging, and minimize the auxiliary power consumption of the charging pile.

[0094] S3. After the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, it means that the charging gun is successfully connected to the electric vehicle and the charging pile needs to charge the electric vehicle, then the charging pile is controlled to exit the sleep mode and enter normal operation.

[0095] S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on that day.

[0096] That is, in this embodiment, the charging main control board detects the communication status with each module of the charging pile in real time, and determines whether the charging pile is available based on whether the communication is abnormal, and then determines whether the charging pile needs to enter low power consumption mode to save power consumption; at the same time, if there is no abnormality in the communication, the charging main control board detects whether the CC1 gun plug signal of the charging gun changes at preset time intervals, so that when the CC1 gun plug signal does not change for a period of time, it is determined that the charging gun in the charging pile is not connected to the electric vehicle at this time. Therefore, in order to further save power consumption, the charging pile is controlled to enter sleep mode; in addition, in order to ensure the intelligent adjustment of the timing of the charging pile entering sleep mode, the preset time for the next day to be used for sleep mode judgment is calculated through the charging, sleep and other data of each day, so as to realize the intelligent adjustment of the time when the charging pile enters sleep mode, improve the intelligent design of the charging pile, and further reduce the energy loss of the charging pile.

[0097] Please refer to Figure 3 , the second embodiment of the present invention is:

[0098] A method for reducing the energy consumption of a charging pile operation. Based on the above embodiment 1, the time when the charging pile enters the sleep mode can be revised in the program, and different time values ​​can be adjusted according to different station conditions.

[0099] It is also possible to calculate and intelligently adjust the time when the charging pile enters sleep mode. Figure 3 As shown, step S4 is specifically as follows:

[0100] S41. The charging pile control board repeats the above steps S1 to S3, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when entering the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5 and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the plug-in signal before entering the sleep mode the next day as T3.

[0101] S42. Calculate the actual dormancy failure rate K'=(C1-C2) / C1 on that day.

[0102] S43. If the actual dormancy failure rate K'>K on that day, it means that there were multiple short charging time intervals that resulted in dormancy failure on that day. In order to reduce the dormancy failure rate and improve the owner's experience, it is necessary to increase the preset time for the next day, that is, enter step S44. Otherwise, it means that the preset time setting of the charging pile system on that day is reasonable or even has a margin. Therefore, the preset time for the next day is reduced, that is, T3=T1-T5.

[0103] S44. If (T1+T5) is greater than (T2+T4), set T3=T1+T5; otherwise, set T3=T2+T5.

[0104] Among them, the longest dormancy failure interval T2, the preset dormancy duration T4, the preset dormancy improvement step duration T5 and the preset dormancy failure rate K can all be set according to the needs of different charging piles at different stations, and the preset dormancy duration is a fixed value that can be obtained through actual testing.

[0105] That is, in this embodiment, due to the differences in stations and daily charging conditions, the judgment of the change in the plug-in signal by the charging main control board at every preset time will also be different. Therefore, the preset time for the next day is calculated accordingly based on the charging and sleep data of the day, so as to realize intelligent adjustment of the time when the charging pile enters sleep mode and improve the intelligent design of the charging pile.

[0106] In addition, in this embodiment, the EMS system can obtain the charging and sleep data of the corresponding charging piles through charging platforms such as charging APPs and WeChat applets on mobile devices. A corresponding charging reservation function can also be designed in the charging APP. Car owners can choose the charging piles with corresponding numbers to make charging reservations, and adjust the corresponding preset time for the reservation of the charging piles through the EMS system to achieve intelligent control.

[0107] In addition, it is worth noting that, in this embodiment, step S2 also includes:

[0108] The charging main control board controls the EMS system to identify holidays. If the EMS system receives information identifying holidays, the charging pile's sleep function is turned off.

[0109] That is, since the number of charging orders for charging piles will increase sharply during holidays, in order to reduce the waiting time for car owners to start charging, the charging main control board adds a holiday recognition function. When a holiday is recognized, the dormant function of the charging pile is completely turned off, maintaining an efficient normal charging mode for car owners throughout the day.

[0110] Please refer to Figure 4 , the third embodiment of the present invention is:

[0111] A terminal 1 for reducing the energy consumption of a charging pile includes a memory 2, a processor 3, and a computer program stored in the memory 2 and executable on the processor 3. When executing the computer program, the processor 3 implements the steps in the first or second embodiment described above.

[0112] In summary, the present invention provides a method and terminal for reducing the energy consumption of charging pile operation, which can shut down the power consumption of non-essential devices during idle periods when the charging pile is not performing charging operations, thereby minimizing the auxiliary power consumption of the charging pile, avoiding long-term power-on operation of devices, and increasing the service life of various devices in the charging pile; at the same time, it can calculate the preset time for the next day's sleep mode judgment through the charging, sleep and other data of each day, realize intelligent adjustment of the time when the charging pile enters sleep, improve the intelligent design of the charging pile, and further reduce the energy loss of the charging pile.

Claims

1. A method for reducing the energy consumption of a charging pile, characterized in that: Including steps: S1. The charging main control board detects the communication status of each module in the charging pile in real time. When a communication abnormality occurs, the charging pile is controlled to enter a low power consumption mode. Otherwise, step S2 is executed. S2. The charging main control board detects whether the plug-in signal of the charging gun changes at a preset time. If no change occurs, the charging pile is controlled to enter the sleep mode; S3, after the charging pile enters the sleep mode, if the charging main control board detects in real time whether the gun plug signal changes, if so, the charging pile is controlled to exit the sleep mode and enter normal operation; S4. Repeat steps S1 to S3 above, and adjust the preset time for interval detection of the plug-in signal before entering the sleep mode the next day according to the working information and sleep information of the charging pile on the day; The step S2 is specifically as follows: The charging main control board detects the plug-in signal of the charging gun at preset intervals. If the plug-in signal does not change within the preset time, the charging pile is controlled to enter a sleep mode, and a sleep instruction is sent to each module in the charging pile to control each module to stop working, and only the identification and judgment of the plug-in signal on the charging gun is retained; The step S2 further includes: The charging main control board controls the EMS system to identify holidays. If information identifying holidays is obtained from the EMS system, the dormancy function of the charging pile is turned off. The step S4 is specifically as follows: S41. The charging pile control board repeats steps S1 to S3 above, and collects the number of charging times C1 of the charging pile on the day, the number of sleep times C2 when the charging pile enters the sleep mode on the day, the preset time interval T1 of the day, the longest sleep failure interval T2 of the day, the preset sleep duration T4, the preset sleep improvement step duration T5, and the preset sleep failure rate K through the EMS, and defines the preset time for interval detection of the gun plug signal before entering the sleep mode on the next day as T3; S42, calculating the actual dormancy failure rate K' = (C1-C2) / C1 on that day; S43. If the actual sleep failure rate K'>K on that day, it means that there were multiple short charging intervals on that day, resulting in sleep failure, and the process goes to step S44.
