[0017] See also Figure 1 , Figure 1A flow chart of a method for adjusting the power of a charging station provided in an embodiment of the present application. The method for adjusting the power of a charging station provided in an embodiment of the present application is applied to a terminal device, and the method is executed by an application software installed in the terminal device. The terminal device may be a desktop computer, a laptop computer, a tablet computer, a mobile phone, etc.

[0018] It should be noted that the application scenarios described in the following embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person of ordinary skill in the art can know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0019] The method for adjusting the power of the charging station is described in detail below.

[0020] like Figure 1 As shown, the method includes the following steps S110~S130.

[0021] S110, determining a first number of charging targets of the charging station in a first time period, and predicting a second number of charging targets of the charging station in a second time period; wherein the first time period and the second time period are two adjacent time periods.

[0022] In this embodiment, the charging target can be a charging electric vehicle, a device to be charged, etc. The first time period can be understood as the time interval between the current moment and the next moment of the charging station, and the second time period can be understood as the time interval between the next moment and a certain moment of the charging station. Among them, the time interval between two adjacent time periods can be zero. The time period refers to the stage divided within a fixed time, which is usually used to describe the duration of an action or state. For example, "the period from 7 to 9 in the morning is the peak traffic period." At the same time, the time period can also be called a time interval, which refers to the time course experienced between two different states of objective material movement, and requires time units to measure.

[0023] Exemplarily, if the first time period is within five minutes after the current time, such as 11:50 am to 11:55 am, then the second time period is within five minutes after five minutes, such as 11:55 am to 12:00 am.

[0024] Specifically, when determining the first number of charging targets of the charging station in the first time period, the information of the electric vehicles being charged in the charging station can be directly obtained for determination. When predicting the second number of charging targets of the charging station in the second time period, the prediction can be made in combination with the historical data of the charging station. Specifically, based on the second time period, the number of charging targets of the charging station in a preset third time period can be obtained to determine the second number of charging targets of the charging station currently in the second time period. The third time period can be a historical time period of the second time period, and the time interval between the third time period and the second time period can be one hour, two hours, one day, two days, one week, one month, half a year, one year, etc.

[0025] At the same time, when the application combines historical data to predict the second number of charging targets, the first number of charging targets in the first time period can also be added to determine. The first number can be understood as the maximum number of charging targets in the first time period, and the second number can be understood as the maximum number of charging targets in the second time period.

[0026] At the same time, when predicting the second number of charging targets in the second time period of the charging station, the increase or decrease in the number of charging targets in the charging station from the first time period to the second time period can be predicted, and then the second number can be determined based on the increase or decrease. Among them, the predicted increase or decrease can be predicted using a regression model, and the indicators for predicting the second number can include weather, holidays, working days, time periods, etc. The formula of the regression model can be: M=ax+by+cz+dh, where M is the increase or decrease, a, b, c, d are the corresponding weights, and x, y, z, h are weather, holidays, working days, and time periods, respectively.

[0027] In addition, the formula of the model for predicting the increase and decrease quantity can also be M=(a+b+c+d)x, where a, b, c, d are the weights of weather, holidays, working days, and time periods, respectively, and x is a fixed number. At the same time, a+b+c+d can be equal to 1, greater than 1, or less than 1. When the second time period is a holiday, the weight b of the holiday can be increased, and when the second time period is not a holiday, the weight b can be reduced, that is, the weights of weather, holidays, working days, and time periods can be dynamically adjusted to obtain a more accurate increase and decrease quantity, so that the second quantity of charging targets of the charging station in the second time period can be more accurately predicted.

[0028] In some embodiments, Figure 2 As shown, step S110 includes steps S111 and S112.

[0029] S111, obtaining at least a third number of charging targets of the charging station in the last first time period and a fourth number of charging targets in the last second time period; S112. Determine a second quantity according to the third quantity, the fourth quantity, and the first quantity.

[0030] Specifically, the present application can also obtain the third number of charging targets of the charging station in the last first time period, the last first time period can be understood as the fourth time period, and the time interval between the fourth time period and the first time period can be one hour, two hours, one day, two days, one week, one month, half a year, one year, etc. After obtaining the third number of charging targets of the charging station in the last first time period and the fourth number of charging targets in the last second time period, the quantitative relationship between the charging targets of the charging station in the first time period and the second time period can be determined, and then based on the quantitative relationship and the first quantity, the second number of charging targets of the charging station in the second time period can be predicted.

[0031] S120. Perform power prediction for the charging station in a second time period based on the first quantity and the second quantity to obtain a predicted charging power of the charging station.

[0032] Specifically, after determining the first number and the second number of charging targets of the charging station in the first time period and the second time period, the number of charging targets added by the charging station in the second time period can be determined, and then the charging power increased by the charging station in the second time period can be determined. Therefore, the total charging power of the charging station in the second time period can be determined based on the charging power of the charging station in the first time period and the charging power increased in the second time period, that is, the predicted charging power, and based on this, the power grid is requested to adjust the charging power of the charging station in the second time period, so as to avoid the impact of unstable load on the power grid caused by the charging station in the second time period, thereby greatly improving the stability of the power grid.

[0033] In some embodiments, Figure 3 As shown, step S120 includes steps S121 and S122.

[0034] S121, obtaining a third remaining charging time and a third remaining power of each charging target within the first time period; S122: According to the third remaining charging time, the third remaining power, the first quantity, and the second quantity, perform power prediction for the charging station in the second time period to obtain predicted charging power.

[0035] Specifically, the charging process of electric vehicle fast charging can be divided into three stages: pre-charging, high-current constant-current charging, and constant-voltage charging. The pre-charging stage is to protect the battery and avoid damage to the battery due to excessive voltage; the high-current constant-current charging stage is a high-rate charging stage with a power level between 20% and 80%; the constant-voltage charging stage prevents the voltage from being too high and damaging the battery structure. The charging period of an electric vehicle is determined by the voltage and current. For a charging pile, the charging period (h) = battery energy (kWh) / charging power (kW). Therefore, increasing the charging power can shorten the charging time, and the charging power is determined by the voltage and current. Power (kW) = voltage (V) * current (A), so if you want to shorten the charging period, you need a large current and high voltage. Therefore, during the fast charging process of an electric vehicle, the charging power decreases with the time period. To this end, the present application needs to obtain the third remaining charging time and the third remaining power of each charging target in the first time period, and then determine the maximum charging power of the charging station in the first time period. At the same time, the increase or decrease in the number of charging vehicles after the charging station enters the second time period from the first time period is determined based on the first number and the second number, and then the predicted charging power of the charging station in the second time period can be obtained.

[0036] In some embodiments, Figure 4 As shown, step S122 includes steps S1221 and S1222.

[0037] S1221. Obtain a second target charging power of each charging target within the first time period; S1222: According to the second target charging power, the third remaining charging time, the third remaining power, the first quantity, and the second quantity, perform power prediction for the charging station in the second time period to obtain predicted charging power.

[0038] Specifically, since car owners generally like to shorten the charging time of their vehicles, the charging vehicles in the charging station may end charging ahead of time, so that the number of charging targets actually increased or decreased by the charging station in the second time period is not the difference between the first number and the second number, and the charging power of the electric vehicle that has just started charging is greater than the charging power of the electric vehicle in the middle and late stages of charging.

[0039] Therefore, the present application also needs to obtain the second target charging power of each charging target in the first time period to determine the number of charging targets actually increased or decreased by the charging station in the second time period, so as to more accurately obtain the predicted charging power of the charging station in the second time period. Among them, the second target charging power can be determined based on the historical charging data of each car owner, or it can be determined based on the charging power set by the car owner. The specific acquisition method can be selected according to the actual application, and this application does not make specific limitations.

[0040] S130. Request the power grid to adjust the charging power of the charging station in the second time period according to the predicted charging power.

[0041] Specifically, after obtaining the predicted charging power of the charging station in the second period, the grid can be requested to allocate the predicted charging power to the charging station in the second period to avoid the impact of unstable load on the grid caused by the charging station in the second period, which greatly improves the stability of the grid. At the same time, in the process of using the predicted charging power to request the grid to adjust the charging power of the charging station in the second period, in order to avoid a sudden increase in the number of vehicles in the charging station, which may cause the grid to be impacted, the charging station needs to increase the additional charging impulse rate on the basis of the predicted charging power to request the grid to adjust the charging power of the charging station in the second period.

[0042] In some embodiments, Figure 5 As shown, step S130 includes steps S131, S132 and S133.

[0043] S131, determining the actual number of charging targets of the charging station in the second time period; S132. Determine a target charging power of the charging station in the second time period according to the actual quantity; S133: Adjust the charging power of the charging station in the second time period according to the target charging power and the predicted charging power.

[0044] In this embodiment, the charging station has actually entered the second time period from the first time period. At this time, the information of the electric vehicles being charged in the charging station can be directly obtained to determine the actual number of charging targets of the charging station in the second time period, and the target charging power of the charging station in the second time period can be determined based on the actual number. The predicted charging power at this time is the power allocated by the power grid to the charging station. Therefore, it can be determined based on the target charging power and the predicted charging power whether the current charging power of the charging station will cause an impact on the power grid, and then the preset energy storage system can be used to adjust the power of the charging station to ensure the stability of the power grid.

[0045] In some embodiments, Figure 6 As shown, step S132 includes steps S1321 and S1322.

[0046] S1321, obtaining a first remaining charging time and a first remaining power of each charging target in the second time period; S1322: Determine a target charging power of the charging station in a second time period according to the first remaining charging duration and the first remaining power.

[0047] In this embodiment, the target charging power can be understood as the maximum charging power that the charging station needs to charge the charging target in the second time period. Since the charging process of electric vehicle fast charging can be divided into three stages: pre-charging, high current constant current charging and constant voltage charging, the charging power of electric vehicles decreases with the time period during the fast charging process. Therefore, this application can obtain the first remaining charging time and the first remaining power of each charging target in the second time period, and then determine the maximum charging power of the charging station in the second time period, that is, the target charging power.

[0048] In some embodiments, Figure 7 As shown, step S1322 includes steps S13221 and S13222.

[0049] S13221. Obtain a first target charging power of each charging target in a second time period; S13222: Determine a target charging power according to a first target charging power, a first remaining charging time, and a first remaining power.

[0050] Specifically, since it is necessary to consider that the car owner may end charging ahead of time, in order to better estimate the maximum charging power of the charging station in the second time period, this application also needs to obtain the first target charging power of each charging target in the second time period, and then determine the maximum charging power of the charging station in the second time period based on the first target charging power, the first remaining charging time and the first remaining power. Among them, when calculating the maximum charging power of the charging station in each time period, the charging power at each moment in each time period can be determined according to the fast charging strategy of each vehicle, and then the charging power of the charging station at each moment in each time period can be calculated and screened to obtain the maximum charging power.

[0051] In some embodiments, Figure 8 As shown, step S133 includes steps S1331 and S1332.

[0052] S1331. If the target charging power is greater than the predicted charging power, obtain a first charging power difference between the target charging power and the predicted charging power; S1332: If the first charging power difference is greater than a preset first threshold, start a preset energy storage system, and adjust the charging power of the charging station according to the energy storage system and the power grid.

[0053] In this embodiment, the first charging power difference is the power value obtained by subtracting the predicted charging power difference from the target charging power difference, and the first threshold value can be understood as the critical value at which the charging station will impact the power grid. In order to further avoid the impact on the power grid, the present application can set an energy storage system at the charging station, so that when the first charging power difference is greater than the first threshold value, the energy storage system can be used for discharge to adjust the power of the charging station, thereby reducing the impact on the power grid.

[0054] In some embodiments, when the first charging power difference is greater than the first threshold, if it is detected in the second time period that the charging power required by the charging target in the charging station reaches the target charging power, the energy storage system can be used to discharge first to achieve charging of the charging vehicle, and when it is detected in the second time period that the charging power required by the charging target in the charging station is reduced to the predicted charging power, the energy storage system is controlled to stop discharging, and the power grid is used to supply power to the charging station. Among them, the energy storage system can use power cells, which are different from common energy cells. Power cells can provide high-power charging and discharging within a certain period of time to balance power fluctuations, and thus can play a role in regulating power.

[0055] In some embodiments, Fig. 9 As shown, step S133 also includes steps S1333 and S1334.

[0056] S1333: If the target charging power is less than the predicted charging power, obtain a second charging power difference between the target charging power and the predicted charging power, and a second remaining power of the preset energy storage system; S1334: If the second remaining power is less than or equal to a preset second threshold, based on the second charging power difference, use a charging station to charge the energy storage system.

[0057] In this embodiment, in order to reduce energy loss and reduce operating costs, the present application can also obtain a second charging power difference between the target charging power and the predicted charging power when the target charging power is less than the predicted charging power, that is, subtract the target charging power from the predicted charging power, and at the same time obtain the remaining power of the standby energy storage system, that is, the second remaining power, and then determine whether the second remaining power is less than or equal to the second threshold to determine whether the energy storage system needs to be charged. If the second remaining power is less than or equal to the second threshold, it is determined that the energy storage system needs to be charged, and then the energy storage system can be charged according to the second charging power difference.

[0058] In the method for adjusting the power of a charging station provided in an embodiment of the present application, a first number of charging targets of the charging station in a first time period is determined, and a second number of charging targets of the charging station in a second time period is predicted; wherein the first time period and the second time period are two adjacent time periods; based on the first number and the second number, a power prediction is performed on the charging station in the second time period to obtain a predicted charging power of the charging station; based on the predicted charging power, a request is made to the power grid to adjust the charging power of the charging station in the second time period, thereby avoiding the impact of the charging station on the power grid due to unstable load in the second time period, thereby greatly improving the stability of the power grid.

[0059] The embodiment of the present application further provides a device 200 for adjusting the power of a charging station, which is used to execute any embodiment of the aforementioned method for adjusting the power of a charging station.

[0060] Specifically, see Fig.10 , Fig.10 It is a schematic block diagram of a device 200 for regulating the power of a charging station provided in an embodiment of the present application.

[0066] In some embodiments, the second prediction unit 220 is also used to obtain the second target charging power of each charging target within the first time period; based on the second target charging power, the third remaining charging time, the third remaining power, the first quantity and the second quantity, the power of the charging station is predicted within the second time period to obtain the predicted charging power.

[0067] The adjustment unit 230 is used to request the power grid to adjust the charging power of the charging station within the second time period according to the predicted charging power.

[0068] In some embodiments, the adjustment unit 230 is also used to determine the actual number of charging targets of the charging station in the second time period; determine the target charging power of the charging station in the second time period based on the actual number; and adjust the charging power of the charging station in the second time period based on the target charging power and the predicted charging power.

[0069] In some embodiments, the adjustment unit 230 is further used to obtain a first remaining charging time and a first remaining power of each charging target in the second time period; and determine a target charging power of the charging station in the second time period based on the first remaining charging time and the first remaining power.

[0070] In some embodiments, the adjustment unit 230 is further used to obtain a first target charging power of each charging target in the second time period; and determine the target charging power according to the first target charging power, the first remaining charging time and the first remaining power.

[0071] In some embodiments, the adjustment unit 230 is also used to obtain a first charging power difference between the target charging power and the predicted charging power if the target charging power is greater than the predicted charging power; if the first charging power difference is greater than a preset first threshold, start a preset energy storage system and adjust the charging power of the charging station according to the energy storage system and the power grid.

[0072] In some embodiments, the adjustment unit 230 is also used to obtain a second charging power difference between the target charging power and the predicted charging power, as well as a second remaining power of the preset energy storage system if the target charging power is less than the predicted charging power; if the second remaining power is less than or equal to a preset second threshold, based on the second charging power difference, the energy storage system is charged using a charging station.

[0073] The device 200 for adjusting the power of a charging station provided in an embodiment of the present application is used to execute the above-mentioned determination of a first number of charging targets of the charging station in a first time period, and predict a second number of charging targets of the charging station in a second time period adjacent to the first time period, and then predict the predicted charging power of the charging station in the second time period based on the first number and the second number, and request the power grid to allocate the corresponding charging power to the charging station in the second time period based on the predicted charging power, so as to adjust the charging power of the charging station, thereby avoiding the impact of unstable load on the power grid caused by the charging station in the second time period, thereby greatly improving the stability of the power grid.

[0074] It should be noted that those skilled in the art can clearly understand that the specific implementation process of the above-mentioned device 200 for adjusting the power of the charging station and each unit can refer to the corresponding description in the aforementioned method embodiment, and for the convenience and brevity of description, it will not be repeated here.

[0075] The above-mentioned device 200 for adjusting the power of the charging station can be implemented in the form of a computer program. The computer program can be used in a computer program such as Fig.11 The electronic device shown is running.
