DETAILED DESCRIPTION

[0018] 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.

[0019] Reference Figure 1 As shown, a power supply control method based on a power exchange cabinet includes: S100, based on the database system, obtaining historical power supply data of the power exchange cabinet; S200, analyzing and processing the battery inside the battery swap cabinet based on the historical power supply data of the battery swap cabinet to obtain the health of the battery; S300, obtaining charging order information based on the charging platform; S400: Analyze and design the charging process of the electric vehicle based on the health of the battery and the charging order information, and obtain a power supply control solution for the battery swap cabinet; S500, obtaining factory specification parameter information of the battery based on the database system; S600: Based on the factory specification parameter information of the battery, the power supply control scheme of the power swap cabinet is corrected to obtain a power supply control correction scheme of the power swap cabinet; Those skilled in the art will understand that the battery swap cabinet charges electric vehicles through the internal batteries. There are multiple groups of batteries installed inside the battery swap cabinet, but the usage time of each group of batteries is different, so the health of the batteries may be different. Batteries that are used more times may have more internal damage, so the charging time will be shorter and cannot meet the needs of electric vehicles. Batteries that are used less times will have less internal damage and can charge more electric vehicles. In addition, when the battery is used to charge an electric vehicle for a long time, the temperature will rise. When the temperature rises to a certain level, the battery will have abnormal loss, causing energy waste and damaging the internal structure of the battery. Therefore, the temperature of the discharging battery is monitored to avoid damage due to high temperature.

[0020] Reference Figure 2 As shown, based on the historical power supply data of the battery swap cabinet, the battery inside the battery swap cabinet is analyzed and processed to obtain the health of the battery, which specifically includes the following steps: S201, filtering and processing the historical power supply data of the battery swap cabinet to obtain relevant data of the battery; S202, classifying and processing relevant data of the battery based on year characteristics to obtain battery data of different years; S203, analyzing and processing the battery data of different years to obtain the battery data of the starting year and the real-time battery data; S204: Based on the battery data of the starting year and the real-time battery data, the conversion efficiency of the battery is analyzed and processed to obtain the health of the battery.

[0021] Reference Figure 3 As shown, based on the battery data of the starting year and the real-time battery data, the battery conversion efficiency is analyzed and processed to obtain the battery health, which specifically includes the following steps: S2041. Based on the battery data of the starting year, extract data from the database system to obtain charging order information of the starting year; S2042, based on the charging order information of the starting year, analyzing and processing the battery data of the starting year to obtain the starting charging time of the battery; S2043, based on the real-time battery data, extracting data from the database system to obtain real-time charging order information; S2044, analyzing and processing the real-time battery data based on the real-time charging order information to obtain the real-time charging time of the battery; S2045, performing calculation processing according to the initial charging time of the battery and the real-time charging time of the battery to obtain the charging degradation time of the battery; S2046, comparing and judging the battery charging degradation time with a set threshold value to obtain the health of the battery; The specific calculation formula for the battery charging degradation time is:

[0022] In the formula, Charge the battery for degradation time; The charging time of the initial charging order information for each battery; is the charging time of each battery's real-time charging order information; n is the number of initial charging order information; k is the number of real-time charging order information; n k; In this embodiment, as the battery usage time increases, the available capacity inside the battery will decrease, and the number of electric vehicles that can be charged will also decrease. Therefore, n is strictly greater than k, because when the battery is first put into use, the number of electric vehicles charged is the largest.

[0023] Reference Figure 4 As shown, based on the comparison between the battery charging degradation time and the set threshold, obtaining the battery health specifically includes the following steps: S20461, judging based on the battery charging degradation time and a set threshold; S20462: if the battery charging degradation time is less than or equal to the set first threshold, outputting the battery health as excellent; S20463: if the battery charging degradation time is greater than the set first threshold, and the battery charging degradation time is less than or equal to the set second threshold, outputting the battery health as good; S20463, if the battery charging degradation time is greater than the set second threshold, outputting the battery health as poor; In this embodiment, the health of the battery is the highest when it is just put into use. Therefore, the year when the battery was put into use is determined by the year, and the charging time of the battery when it was just put into use is determined. Then, the current battery is analyzed to determine the current charging time of the battery. The two are calculated to obtain the battery charging degradation time. The battery charging degradation time is compared with the set threshold to determine the battery health level. Excellent batteries can be maintained, and poor batteries can be replaced.

However, the remaining energy of the excellent battery may not be able to meet the charging needs of the electric vehicle, so it is necessary to make a judgment and design a power supply control plan for the battery swap cabinet.

When the temperature rises to a certain level, the internal materials of the battery will degrade and be damaged, causing the battery capacity to decrease. In addition, if the battery is exposed to high temperatures for a long time, the battery will experience abnormal wear and tear. When the battery suffers abnormal wear and tear, the remaining battery capacity may not be able to meet the charging needs of the electric vehicle.
