DETAILED DESCRIPTION

[0025] 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.

[0026] Reference Figure 1 As shown, a method for monitoring operation errors based on a DC charging pile includes: S100, based on the central control platform, read the data of the order platform to obtain the charging power, charging unit price, total charging amount, charging time, charging device type and the first remaining energy of the charging device; S200, calculating and processing according to the charging power of the charging pile, the charging unit price, the charging time and the total charging amount to obtain the remaining charging amount; The specific calculation formula for obtaining the remaining amount of charging is:

[0027] In the formula, The remaining amount for charging; is the total amount of charging; Charging power for charging pile; Is the charging time; is the charging unit price; S300: Analyze the type of charging equipment based on the central control platform to obtain the real-time charging power; S400, based on the charging power of the charging pile and the real-time charging power, correct the remaining amount of charging to obtain a corrected remaining amount of charging; S500, analyzing and processing the corrected remaining amount of charging, the real-time charging power, and the charging unit price to obtain the charging completion time; It will be understood by those skilled in the art that when a user places an order through an order platform to charge a charging device, when the order platform fails, the relevant parameters within the order platform will become abnormal, which may result in the charging amount ordered by the user being unable to replenish the charging device with the electric energy corresponding to the charging amount. In addition, the charging power and the real-time charging power of the charging pile are analyzed. When there is a large error between the charging power and the real-time charging power of the charging pile, it means that there is an abnormality in the DC charging pile. Therefore, a power compensation amount is introduced to compensate for the remaining charging amount to ensure that the user's charging amount can enable the charging device to reach the corresponding energy state.

[0028] Reference Figure 2 As shown, based on the central control platform, analyzing the charging device type and obtaining the real-time charging power specifically include the following steps: S301, based on the type of charging device, perform information retrieval on the database system to obtain the communication protocol corresponding to the charging device; S302: The central control platform establishes a communication connection with the charging device based on the communication protocol corresponding to the charging device; S303, based on the central control platform, sending a data transmission instruction to the charging device to obtain the second residual energy of the charging device; S304, performing calculation and processing according to the first remaining energy of the charging device and the second remaining energy of the charging device to obtain charged energy information; S305, performing calculations based on the charged energy information and the charging time to obtain the real-time charging power; The specific calculation formula for obtaining the real-time charging power is:

[0029] In the formula, Real-time power for charging; It is the second surplus energy source for charging equipment; It is the first surplus energy source for charging equipment; Is the charging time; In this embodiment, when the charging device is charging, the order platform will display the relevant parameters of the charging device, that is, the type of charging device. The central control platform will search for information in the database system according to the type of charging device, and determine the communication protocol corresponding to the charging device. The central control platform will establish a communication connection with the charging device according to the communication protocol corresponding to the charging device, read the energy information that has been replenished by the charging device, and then calculate based on the remaining energy information of the charging device when not charging and the charging time, and determine the real-time charging power, so that the subsequent combined analysis with the charging power of the charging pile will be more accurate.

[0030] Reference Figure 3 As shown, based on the charging power of the charging pile and the real-time charging power, the remaining amount of charging is corrected, and obtaining the corrected remaining amount of charging specifically includes the following steps: S401. Based on the central control platform, the charging power and the real-time charging power of the charging pile are calculated and processed to obtain a power offset; S402, performing judgment processing according to the power offset and the set first threshold to determine the power compensation amount, where the power compensation amount includes a first compensation amount and a second power compensation amount; S403, based on the power compensation amount and the charging unit price, correct the remaining amount of charging to obtain a corrected remaining amount of charging, wherein the corrected remaining amount of charging includes a first corrected remaining amount of charging and a second corrected remaining amount of charging; The specific calculation formula for obtaining the power offset is:

[0031] In the formula, is the power offset; Charging power for charging pile; Real-time power for charging; In this embodiment, when an abnormality occurs in the DC charging pile, the difference between the output power of the charging pile and the input power of the charging device will be abnormal. Therefore, in order to enable the charging device to reach the corresponding state with the total charging amount of the user, a power compensation amount is introduced here to correct the remaining charging amount, thereby ensuring that the total charging amount of the user obtains the corresponding power resources.

[0032] Reference Figure 4 As shown, judging and processing are performed according to the power offset and setting the first threshold, and determining the power compensation amount specifically includes the following steps: S4021, making a judgment according to the power offset and a set first threshold; S4022: If the power offset is greater than the set first threshold, output the first power compensation amount. ; S4023: If the power offset is equal to the set first threshold, the output charging pile charging power is the same as the real-time charging power, and there is no need to correct the remaining amount of charging; S4024: If the power offset is less than the set first threshold, the second power compensation amount is output ; In this embodiment, the first power compensation amount is a positive value, because there is a difference between the output power of the DC charging pile and the input power of the charging device, and the input power of the DC charging pile is greater than the input power of the charging device, that is, the charging power of the charging pile is greater than the real-time charging power, and the second power compensation amount is a negative value, that is, the real-time power of the charging pile is less than the real-time charging power, but this phenomenon is impossible to occur in real life, that is, the order platform has an abnormality. In this case, the energy charged for the total charging amount is too much, so the remaining charging amount is corrected by the second power compensation amount.

[0033] Reference Figure 5 As shown, based on the power compensation amount and the charging unit price, the remaining amount of charging is corrected, and obtaining the corrected remaining amount of charging specifically includes the following steps: S4031, if the power compensation amount is the first power compensation amount ; S4032: based on the first power compensation amount and the charging unit price, correct the remaining amount of charging to obtain a first corrected remaining amount of charging; The specific calculation formula for obtaining the first modified charging remaining amount is:

[0034] In the formula, Charge the remaining amount for the first amendment; The remaining amount for charging; is the first power compensation amount; Is the charging time; is the charging unit price; S4033: If the power compensation amount is the second power compensation amount ; S4034. Based on the second power compensation amount and the charging unit price, the remaining amount of charging is corrected to obtain a second corrected remaining amount of charging; The specific calculation formula for obtaining the second modified charging remaining amount is:

[0035] In the formula, Charge the remaining amount for the second amendment; The remaining amount for charging; is the second power compensation amount; Is the charging time; The unit price for charging.

[0036] Reference Figure 6 As shown, according to the correction of the remaining amount of charging, the real-time charging power and the charging unit price, the analysis and processing to obtain the charging completion time specifically includes the following steps: S501, performing calculation based on the corrected remaining charging amount, the real-time charging power and the charging unit price to obtain the remaining charging time, where the remaining charging time includes a first remaining charging time and a second remaining charging time; S502, calculating and processing according to the remaining charging time and the charged time to obtain the charging completion time, where the charging completion time includes a first charging completion time and a second charging completion time; In this embodiment, when the revised charging remaining amount is the first revised charging remaining amount or the second revised charging remaining amount, the charging completion time will also be different. When the revised charging amount is the first revised charging remaining amount, it means that there is an abnormality in the DC charging pile, and the total charging amount cannot obtain the corresponding power resources. Therefore, the charging time needs to be extended so that the total charging amount can obtain the corresponding power resources. When the revised charging amount is the second revised charging remaining amount, it means that there is an abnormality in the display of the order platform. The display parameters of the order platform are corrected to ensure that the user can get the correct charging completion time. It is worth noting that the first charging completion time is greater than the second charging completion time.

[0037] Reference Figure 7 As shown, the calculation and processing based on the corrected remaining charging amount, the real-time charging power and the charging unit price to obtain the remaining charging time specifically includes the following steps: S5011, if the revised charging remaining amount is the first revised charging remaining amount; S5012.

[0039] In the formula, The remaining time for the second charge; Charge the remaining amount for the second amendment; Real-time power for charging; The unit price for charging.

[0040] Reference Figure 8 As shown, the calculation and processing are performed based on the remaining charging time and the charged time, and the charging completion time is obtained, which specifically includes the following steps: S5021: If the remaining charging time is the first remaining charging time; S5022: Calculate and process the first charging remaining time and the charging time to obtain the first charging completion time; S5023: If the remaining charging time is the second remaining charging time; S5024: Calculate and process according to the second remaining charging time and the charged time to obtain the second charging completion time.
