[0052] Figure 3 This is a schematic diagram of the charging power regulation device of the present invention.

[0053] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0054] Reference Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the charging power regulation method of the present invention.

[0055] The charging power regulation method in this embodiment is applied to the charging power regulation system in the charging station of new energy electric vehicles. The charging power regulation system can be applied to intelligent devices such as terminal equipment and PC terminals. For ease of description, the charging power regulation system is used as an example for explanation.

[0056] The charging power regulation method includes:

[0057] Step S10: Determine the first current total charging power of the fast charging area of ​​the charging station and the second current total charging power of the slow charging area of ​​the charging station.

[0058] In this embodiment, when the charging power control system determines that a new energy electric vehicle needs to connect to a charging pile at the charging station, it first calculates the first current total charging power of the fast charging area and the second current total charging power of the slow charging area. It should be noted that the charging station is pre-divided into three areas: a fast charging area, a slow charging area, and a variable charging area. Charging piles in the fast charging area can charge the vehicle according to its rated charging power, achieving fast charging. Charging piles in the slow charging area charge the vehicle according to a set power. The variable charging area determines the charging power of each charging pile based on the current total charging power of the fast charging area and the slow charging area, thus charging the vehicle accordingly.

[0059] Specifically, step S10 includes:

[0060] Step S101: Obtain the first number of charging piles in operation in the fast charging area of ​​the charging station, and determine the first current total charging power of the fast charging area of ​​the charging station based on the first number and the first current charging power corresponding to the charging piles in the fast charging area of ​​the charging station.

[0061] In this step, the charging power control system obtains the first number of charging piles operating in the fast charging area of ​​the charging station, and determines the first current total charging power of the fast charging area based on the first number and the first current charging power corresponding to each charging pile in the fast charging area. Generally, the first current charging power corresponding to each charging pile in the fast charging area is the same, so the charging power control system multiplies the first number and the first current charging power to calculate the first current total charging power of the fast charging area. Optionally, when some vehicles that do not support fast charging enter the fast charging area of ​​the charging station for charging, this may result in the first current charging power of some charging piles operating in the fast charging area being lower. In this case, the charging power control system obtains the first current charging power corresponding to each charging pile operating in the fast charging area and adds all the first current charging powers to obtain the first current total charging power.

[0062] Step S102: Obtain the second number of charging piles working in the slow charging area of ​​the charging station, and determine the second current total charging power of the slow charging area of ​​the charging station based on the second number and the second current charging power corresponding to the charging piles in the slow charging area of ​​the charging station.

[0063] In this step, the charging power control system obtains the second number of charging piles operating in the slow charging area of ​​the charging station, and determines the second current total charging power of the slow charging area of ​​the charging station based on the second number and the second current charging power corresponding to each charging pile in the slow charging area of ​​the charging station. Generally, the second current charging power corresponding to each charging pile in the slow charging area of ​​the charging station is the same. The charging power control system multiplies the second number and the second current charging power to calculate the second current total charging power of the slow charging area of ​​the charging station.

[0064] Step S20: Determine the charging power corresponding to the charging pile in the variable charging area of ​​the charging station based on the first current total charging power, the second current total charging power, and the rated total power of the charging station.

[0065] In this embodiment, after determining the first current total charging power in the fast charging area and the second current total charging power in the slow charging area of ​​the charging station, the charging power control system obtains the rated total power of the charging station. Then, based on the first current total charging power, the second current total charging power, and the rated total power of the charging station, it determines the charging power corresponding to the charging piles operating in the variable charging area of ​​the charging station. It should be noted that the charging power control system prioritizes ensuring that the charging piles in the fast charging area can reach the power required for fast charging of the vehicle, and that the charging piles in the slow charging area can reach the second current charging power. It then adjusts the charging power corresponding to the charging piles operating in the variable charging area so that the total charging power of the fast charging area, slow charging area, and variable charging area does not exceed the rated total power of the charging station.

[0066] Specifically, step S20 includes:

[0067] Step S201: Determine the current available total power of the variable charging area of ​​the charging station based on the first current total charging power, the second current total charging power, and the rated total power of the charging station;

[0068] In this step, the charging power control system determines the current available total power of the variable charging area of ​​the charging station based on the first current total charging power, the second current total charging power, and the rated total power of the charging station. It can be understood that the current available total power refers to the maximum total charging power that the variable charging area of ​​the charging station can currently achieve.

[0069] Further, step S201 includes:

[0070] Step S2011: Calculate the sum of the first current total charging power and the second current total charging power, and calculate the difference between the rated total power of the charging station and the sum. Determine the current available total power of the variable charging area of ​​the charging station based on the difference.

[0071] In this step, the charging power control system first calculates the sum of the first and second current total charging power, then obtains the difference between the rated total power of the charging station and the sum, and determines the current available total power of the variable charging area of ​​the charging station based on the difference; specifically, the formula for calculating the current available total power is: P III =P 站 -(P I +P II ), where P III P represents the total available power at present. 站 P is the rated total power of the charging station. I P is the first current total charging power. II This represents the second current total charging power.

[0072] Step S202: Obtain the third number of charging piles in operation in the variable charging area of ​​the charging station, and determine the current maximum total power of the variable charging area of ​​the charging station based on the third number and the maximum charging power corresponding to the charging piles in the variable charging area of ​​the charging station.

[0073] In this step, the charging power control system obtains the third number of charging piles operating in the variable charging area of ​​the charging station, and determines the current maximum total power of the variable charging area of ​​the charging station based on the third number and the maximum charging power corresponding to each charging pile in the variable charging area of ​​the charging station. Generally speaking, the maximum charging power corresponding to each charging pile in the variable charging area of ​​the charging station is the same. Under the maximum charging power, the charging piles in the variable charging area of ​​the charging station can fast charge the car. The charging power control system multiplies the third number and the maximum charging power to calculate the maximum charging power of the variable charging area of ​​the charging station.

[0074] Step S203: Determine the charging power corresponding to the charging pile in the variable charging area of ​​the charging station based on the current available total power and the current maximum total power.

[0075] In this step, after determining the current available total power and the current maximum total power of the variable charging area of ​​the charging station, the charging power control system determines and adjusts the charging power corresponding to each charging pile in operation in the variable charging area of ​​the charging station based on the current available total power and the current maximum total power, thereby preventing the total charging power of the fast charging area, the slow charging area and the variable charging area of ​​the charging station from exceeding the rated total power of the charging station.

[0076] Specifically, step S203 includes:

[0077] Step S2031: Compare the current available total power with the current maximum total power;

[0078] Step S2032: If it is determined that the current available total power is not less than the current maximum total power, then the charging power corresponding to the charging pile in the variable charging area of ​​the charging station is determined to be the maximum charging power.

[0079] Step S2033: If it is determined that the current available total power is less than the current maximum total power, then the charging power corresponding to the charging pile in the variable charging area of ​​the charging station is determined according to the current available total power.

[0080] In steps S2031 to S2033, the charging power control system compares the current available total power and the current maximum total power of the variable charging area of ​​the charging station to obtain a comparison result. If the comparison result shows that the current available total power is not less than the current maximum total power, it means that all charging piles in the variable charging area of ​​the charging station can use the maximum charging power to charge the car, and thus the charging power corresponding to the charging pile in the variable charging area of ​​the charging station is determined to be the maximum charging power. If the comparison result shows that the current available total power is less than the current maximum total power, it means that none of the charging piles in the variable charging area of ​​the charging station can use the maximum charging power to charge the car, and the charging power corresponding to the charging pile in the variable charging area of ​​the charging station is determined based on the current available total power.

[0081] Further, the step of determining the charging power corresponding to the charging piles operating in the variable charging area of ​​the charging station based on the currently available total power includes:

[0082] Step S20331: Obtain the third number of charging piles in operation in the variable charging area of ​​the charging station, and calculate the maximum supported charging power based on the third number and the current available total power.

[0083] Step S20332: Determine the charging power corresponding to the charging pile in the variable charging area of ​​the charging station as the maximum supported charging power.

[0084] In steps S20331 to S20332, the charging power control system obtains the third number of charging piles operating in the variable charging area of ​​the charging station, and calculates the maximum supported charging power based on the third number and the current total available power. The charging power corresponding to each charging pile operating in the variable charging area of ​​the charging station is then determined as the maximum supported charging power. It should be noted that the maximum supported charging power is the maximum charging power currently available for each charging pile operating in the variable charging area of ​​the charging station; the formula for calculating the maximum supported charging power is: P = P0 II / N, where P is the maximum supported charging power, P II The current available total power is represented by N, which is a third quantity, meaning the current available total power is evenly distributed among each charging station operating in the variable charging area.

[0085] Further, after step S20, the following is included:

[0086] Step S30: Control the charging piles in the fast charging area of ​​the charging station to charge at the first current charging power, control the charging piles in the slow charging area of ​​the charging station to charge at the second current charging power, and control the charging piles in the variable charging area of ​​the charging station to charge at the maximum charging power or the maximum supported charging power.

[0087] In this step, after the charging power control system determines the charging power of each charging pile in the variable charging area of ​​the charging station, it controls the charging piles in the fast charging area of ​​the charging station to charge at the first current charging power, controls the charging piles in the slow charging area of ​​the charging station to charge at the second current charging power, and controls the charging piles in the variable charging area of ​​the charging station to charge at the maximum charging power or the maximum supported charging power, thereby ensuring that the total charging power of the fast charging area, the slow charging area and the variable charging area of ​​the charging station exceeds the rated total power of the charging station.

[0088] The charging power regulation system in this embodiment determines the first current total charging power of the fast charging area and the second current total charging power of the slow charging area of ​​the charging station. Based on the first current total charging power, the second current total charging power, and the rated total power of the charging station, it determines the charging power corresponding to the charging piles operating in the variable charging area of ​​the charging station. By using the first current total charging power of the fast charging area, the second current total charging power of the slow charging area, and the rated total power of the charging station, the system determines the charging power corresponding to the charging piles operating in the variable charging area of ​​the charging station, ensuring that the total charging power of the fast charging area, the slow charging area, and the variable charging area of ​​the charging station does not exceed the rated total power of the charging station, thereby reducing the impact on the power grid caused by the charging of new energy electric vehicles.

[0089] In practice, the charging station is pre-divided into three areas: the fast charging area (Area I), the slow charging area (Area II), and the variable charging area (Area III).

[0090] like Figure 2 As shown, after the charging power control system of the charging station is initialized and started, it prioritizes the allocation of charging power to charging piles in Zone I and Zone III, so that the charging power of N1 charging piles in Zone I reaches P1 (the first current charging power), and the charging power of N2 charging piles in Zone II reaches P2 (the second current charging power); the charging power control system collects the P power of Zone I in real time. I (First current total charging power) and P in Region II II (Second current total charging power), and determine the number of charging piles in operation in Zone III, then subtract P from P station (rated total charging power of the charging station). I and P in Region II II This will give you P in region III. III(Currently available total power); The charging power control system determines N3*P1 (current maximum total power) for Zone III based on the number of charging piles (N3) in operation in Zone III and the corresponding P1 (maximum charging power) of the charging piles in Zone III, and then compares N3*P1 with P... III Compare and determine whether N3*P1 is not greater than P. III If yes, then determine the charging power corresponding to each charging pile in operation in Zone III as P1; otherwise, calculate the maximum supported charging power (P1) of each charging pile in operation in Zone III. III / N3), determine the charging power corresponding to each charging pile in Zone III as P III / N3.

[0104] Compare the current available total power with the current maximum total power;

[0106] If it is determined that the current available total power is less than the current maximum total power, then the charging power corresponding to the charging pile in the variable charging area of ​​the charging station is determined based on the current available total power.
