Charging piles can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Most charging piles are public charging piles, which generally provide two charging methods: conventional charging and fast charging.

[0079] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0080] Reference Figure 1 As shown, a leakage monitoring and precise control method based on a battery vehicle charging pile includes:

[0081] S100, based on the charging platform, obtaining battery charging power information of the battery vehicle and battery remaining energy information of the battery vehicle;

[0082] S200, based on the charging pile, obtaining battery charging time and charged energy data;

[0083] S300, performing calculation, analysis and processing based on the charged energy data and the battery charging time to obtain average power information of the charging pile port;

[0084] S400, analyzing and determining the average power information of the charging pile port and the battery charging power information of the battery vehicle to obtain the real-time status information of the charging pile port;

[0085] S500, analyzing and judging the remaining energy information of the battery and the charged energy data of the battery vehicle to obtain charging pile port correction information;

[0086] S600, analyzing the real-time status information of the charging pile port according to the charging pile port correction information, determining the status of the charging pile port, selecting whether to perform a self-test on the charging pile port, and obtaining a self-test result;

[0087] S700, based on the charging platform, obtaining battery vehicle charging order information;

[0088] S800, analyzing the battery vehicle charging order information according to the self-test result, and obtaining the operation result;

[0089] It will be understood by those skilled in the art that when an electric vehicle is charging at a charging pile port, leakage may occur at the charging pile port. In order to reduce charging costs and protect personal safety, power analysis is performed on the charging pile port to determine real-time status information of the charging pile port, and then the remaining energy information of the battery and the charged energy data of the electric vehicle are analyzed and judged to obtain correction information of the charging pile port. The real-time status information of the charging pile port is corrected with the correction information of the charging pile port to determine the status of the charging pile port. The status of the charging pile port is then analyzed to determine whether to perform self-inspection on the charging pile port. The charging pile is repaired according to the self-inspection results, thereby ensuring that leakage at the charging pile port can be discovered in time and the charging cost is reduced.

[0090] Reference Figure 2 As shown, the calculation and analysis are performed based on the charged energy data and the battery charging time to obtain the average power information of the charging pile port, which specifically includes the following steps:

[0091] S301, establishing a rectangular coordinate system according to power and time, setting time as a parameter to the X-axis, and setting power as a parameter to the Y-axis;

[0092] S302, drawing a curve based on the charged energy data and the battery charging time to obtain a power change curve;

[0093] S303, analyzing the power variation curve to obtain a power near zero point;

[0094] S304, based on the power near zero point, intercept the power change curve to obtain the actual charging time of the battery;

[0095] S305, performing calculations based on the actual charging time of the battery and the charged energy data to obtain average power information of the charging pile port;

[0096] The specific calculation formula for obtaining the average power information of the charging pile port is:

[0097]

[0098] In the formula, The average power information of the charging pile port; It is the data of charged energy; The battery charging time; The power is close to zero;

[0099] In this embodiment, if the calculation is performed according to the battery charging time, the average power information of the charging pile port obtained may be too small. This is because when the charging pile is charging the battery vehicle, after the battery vehicle is fully charged, the battery vehicle will use part of the energy to ensure its own status. Therefore, the charging pile port will continue to charge the battery vehicle, but the charging power will decrease. Therefore, the power change curve is analyzed to determine that the power is close to zero, but the power close to zero is not zero because the battery vehicle needs to consume part of the energy. Therefore, the charging pile port will continue to charge the battery vehicle, but the charging power will be very small. Therefore, the power change curve is intercepted by the power close to zero to determine the actual charging time of the battery, which reduces the error of subsequent analysis and improves the accuracy of leakage analysis of the charging pile port.

[0100] Reference Figure 3 As shown, according to the average power information of the charging pile port and the battery charging power information of the battery vehicle, the analysis and judgment processing are performed to obtain the real-time status information of the charging pile port, which specifically includes the following steps:

[0101] S401, calculating and processing according to the average power information of the charging pile port and the battery charging power information of the battery vehicle to obtain a power offset;

[0102] S402, performing judgment processing based on the power offset and a set first threshold;

[0103] S403: If the power offset is greater than the set first threshold, output the charging pile port status to be verified information;

[0104] S404: If the power offset is less than or equal to the set first threshold, the output charging pile port status is normal;

[0105] In this embodiment, when the charging pile port is charging the battery vehicle, the battery temperature and the outside temperature will cause the port to heat up, resulting in energy consumption. Therefore, a first threshold is introduced here for comparison with the power offset. If the power offset is greater than the first threshold, the charging pile port may have leakage, which requires further analysis.

[0106] Reference Figure 4 As shown, the analysis and judgment processing based on the battery remaining energy information and the charged energy data of the battery vehicle to obtain the charging pile port correction information specifically includes the following steps:

[0107] S501, performing calculations and processing based on the remaining energy information and charged energy data of the battery of the battery vehicle to obtain real-time energy information of the battery;

[0108] S502, performing judgment processing based on the real-time energy information of the battery and setting a second threshold;

[0109] S503: if the real-time energy information of the battery is greater than or equal to the set second threshold, outputting that the battery charging is completed;

[0110] S504: If the real-time energy information of the battery is less than the set second threshold, output that the battery charging is not completed.

[0111] Reference Figure 5 As shown, the real-time status information of the charging pile port is analyzed according to the charging pile port correction information, the charging pile port status is determined, and whether to perform self-test on the charging pile port is selected. The self-test result is obtained, which specifically includes the following steps:

[0112] S601: If the charging pile port correction information indicates that the battery charging is not completed, it is determined that the charging pile port is abnormal, and the charging pile sends the charging pile port abnormal information to the charging platform, and there is no need to perform self-check on the charging pile port;

[0113] S602: If the charging pile port correction information is that the battery charging is completed, and the charging pile port real-time status information is that the charging pile port status is pending verification information, the charging pile port is subjected to a first self-test process to obtain a first self-test result;

[0114] S603: Analyze and process the result of the first self-test, and select whether to perform a second self-test on the charging pile port.

[0115] Reference Figure 6 As shown, the first self-test processing is performed on the charging pile port, and obtaining the first self-test result specifically includes the following steps:

[0116] S6021. Obtaining the temperature of the charging battery and the external environment temperature;

[0117] S6022, based on the database, perform retrieval processing according to the charging battery temperature and the external environment temperature to obtain temperature consumption energy information;

[0118] S6023, performing judgment processing based on temperature consumption energy information and power offset;

[0119] S6024: If the temperature consumption energy information is equal to the power offset, it is determined that there is no abnormality in the charging pile port;

[0120] S6025: If the temperature consumption energy information is less than the power offset, it is determined that the charging pile port is abnormal;

[0121] It can be understood by those skilled in the art that excessively high external temperature or excessively high temperature of the charging port may cause increased charging power consumption. Therefore, the temperature consumption energy information is introduced as the first self-test parameter. If the temperature consumption energy information is equal to the power offset, there is no abnormality in the charging pile port. If the temperature consumption energy information is less than the power offset, the charging pile port is abnormal. A second self-test is performed on the charging pile port to ensure that there is no misjudgment.

[0122] Reference Figure 7 As shown, based on the analysis and processing of the first self-test result, selecting whether to perform a second self-test on the charging pile port specifically includes the following steps:

[0123] S6031. If the result of the first self-test is that there is no abnormality in the charging pile port, there is no need to perform a second self-test on the charging pile port;

[0124] S6032. If the result of the first self-test is that the charging pile port is abnormal, perform a second self-test on the charging pile port;

[0125] S6033, analyzing the battery vehicle charging order information and the battery charging time, obtaining the remaining battery vehicle charging order information, and transmitting the remaining battery vehicle charging order information to a database for storage;

[0126] S6034. Based on the abnormality of the charging pile port, a second self-test is started for the charging pile port, and a second self-test result is obtained;

[0127] In this embodiment, if an abnormality occurs at the charging pile port and the electric vehicle is still charging, the electric vehicle charging order information and the battery charging time are analyzed to determine the remaining electric vehicle charging order information. When the electric vehicle changes the port, it can continue to charge according to the remaining electric vehicle charging order information, thereby avoiding an increase in costs.

[0128] Reference Figure 8 As shown, based on the abnormality of the charging pile port, the second self-test of the charging pile port is started, and obtaining the second self-test result specifically includes the following steps:

[0129] S60341. After determining that the charging pile port is abnormal, the charging platform sets a delayed self-check time for the port, and the charging platform starts timing to obtain timing information;

[0130] S60342: When the timing information is equal to the port delay self-test time, the charging pile port starts the second self-test;

[0131] S60343: The charging platform sets a first self-check time, monitors the battery energy of the charging pile port and the battery vehicle in real time according to the first self-check time, and obtains a first self-check power of the charging pile port and a first charging power of the battery of the battery vehicle;

[0132] S60344. The charging platform sets a second self-check time, monitors the battery energy of the charging pile port and the battery vehicle in real time according to the second self-check time, and obtains the second self-check power of the charging pile port and the second charging power of the battery of the battery vehicle;

[0133] S60345, respectively, performing calculations based on the first self-test power of the charging pile port, the first charging power of the battery of the battery vehicle, the second self-test power of the charging pile port, and the second charging power of the battery of the battery vehicle to obtain a second self-test result;

[0134] In this embodiment, after the charging pile port leaks electricity, the port delayed self-test time is set to a delay of 180 seconds. When the timing information reaches 180 seconds, the charging pile port starts the second self-test, and the first self-test time is set to a delay of 5 seconds. The first self-test power of the charging pile port and the first charging power of the battery of the electric vehicle are recorded within 5 seconds. After the recording is completed, the charging pile port is started again, and the second self-test time is set to a delay of 10 seconds. The second self-test power of the charging pile port and the second charging power of the battery of the electric vehicle are recorded within 10 seconds. Two real-time monitorings are performed to prevent false alarms.

[0135] Reference Fig. 9 As shown, the calculation and processing are performed based on the first self-test power of the charging pile port, the first charging power of the battery of the battery vehicle, the second self-test power of the charging pile port, and the second charging power of the battery of the battery vehicle, respectively, and obtaining the second self-test result specifically includes the following steps:

[0136] S603451. Calculate and process the first self-test power of the charging pile port and the first charging power of the battery of the battery vehicle to obtain a first self-test offset;

[0137] S603452, calculating and processing according to the second self-test power of the charging pile port and the second charging power of the battery of the battery vehicle to obtain a second self-test offset;

[0138] S603453, performing judgment processing based on the self-check first offset, the self-check second offset and the set third threshold;

[0139] S603454: If the first self-test offset is greater than the set third threshold, and the second self-test offset is greater than the set third threshold, the output charging pile port is abnormal;

[0140] S603455: If the first self-test offset is greater than the set third threshold, and the second self-test offset is less than or equal to the set third threshold, the output charging pile port is normal.

[0141] Reference Fig.10 As shown, the battery vehicle charging order information is analyzed according to the self-test results, and the operation results are obtained, which specifically include the following steps:

[0142] S801. If the second self-check result is that the charging pile port is abnormal;

[0143] S802, the charging platform closes the charging pile port, terminates charging, and the battery vehicle changes the charging pile port. The charging platform reads the remaining battery vehicle charging order information in the database, and the charging platform charges the battery vehicle according to the remaining battery vehicle charging order information;

[0144] S803, the charging platform outputs the charging pile port maintenance information;

[0145] S804: If the second self-check result shows that the charging pile port is normal, the battery vehicle continues to charge;

[0146] In this embodiment, when the charging pile port is determined to be abnormal, the electric vehicle needs to replace the port for charging. In order to avoid the loss of the electric vehicle charging order information, the remaining electric vehicle charging order information is read from the database to charge the electric vehicle, thereby avoiding the increase in charging costs. At the same time, maintenance information is sent to the staff to avoid accidental touch and personal injury.
