[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Figure 1 It is a flow chart of the charging pile charging control method of the embodiment of the present invention. It should be noted that if there is substantially the same result, the charging pile charging control method of the present invention is not based on Figure 1 The process sequence shown is limited. Figure 1 As shown, the charging pile charging control method mainly includes the following steps:

[0036] S101, obtaining the current charging pile required charging power, the total load power of the current photovoltaic power grid, the photovoltaic power generation forecast power of the current photovoltaic power grid, and the load power of other charging piles in the system where the current charging pile is located;

[0038] In some embodiments, judging the power supply type of the current charging pile according to the current charging pile required charging power, the total load power, the photovoltaic power generation predicted power, and the load power of the other charging piles includes:

[0039] The power supply type of the current charging pile is determined according to the required charging power of the current charging pile, the total load power, the predicted photovoltaic power generation power and the load power of the other charging piles, and a power supply type arbitration value is determined. When the power supply type arbitration value is greater than a preset value, the power supply type of the current charging pile is determined to be photovoltaic power grid power supply; otherwise, the power supply type of the current charging pile is determined to be conventional power grid power supply.

[0040] In a specific embodiment, the power supply type of the current charging pile includes photovoltaic power grid power supply or conventional power grid power supply. The current charging pile uses photovoltaic power grid power supply or conventional power grid power supply. The conventional power grid can be a power grid connected to the mains. The above preset value can be determined according to actual needs. When the power supply type arbitration value is greater than the preset value, it is determined that the power supply type of the current charging pile is photovoltaic power grid power supply, otherwise it is determined that the power supply type of the current charging pile is conventional power grid power supply.

[0041] In some embodiments, determining the power supply type of the current charging pile and determining the power supply type arbitration value according to the current charging pile required charging power, the total load power, the photovoltaic power generation predicted power, and the load power of the other charging piles includes:

[0042] The power supply type of the current charging pile is determined according to the current charging pile required charging power, the total load power, the photovoltaic power generation predicted power, the load power of the other charging piles and an arbitration formula, and the power supply type arbitration value is determined. The arbitration formula includes

[0043] C(t)=CarNeed(t)*k1+SystemLoad(t)*k2+Power(t)*k3+WorkState(t)*k4

[0044] Among them, C(t) is the arbitration value of the power supply type, CarNeed(t) is the charging power required by the current charging pile, SystemLoad(t) is the total load power, Power(t) is the predicted photovoltaic power generation power, WorkState(t) is the load power of other charging piles, k1, k2, k3, k4 are the first weight coefficient, the second weight coefficient, the third weight coefficient and the fourth weight coefficient respectively.

[0045] In a specific embodiment, CarNeed(t) is the required charging power of the current charging pile, that is, the required charging power of the current charging pile corresponding to the car, and its size will change over time during the charging process; SystemLoad(t) is the total load power of the current photovoltaic power grid, and the current charging pile can obtain the total load power of the current photovoltaic power grid through the physical link with the photovoltaic power generation system; Power(t) is the predicted photovoltaic power generation power of the current photovoltaic power grid, and WorkState(t) is the load power of other charging piles in the system where the current charging pile is located. The system where the current charging pile is located can be the charging system where the current charging pile is located. The load power of other charging piles in the system where the current charging pile is located can be obtained through the current charging pile's own WIFI or network port local networking transmission information.

[0046] In a specific embodiment, the first weight coefficient k1, the second weight coefficient k2, the third weight coefficient k3 and the fourth weight coefficient k4 all take values ​​between 0 and 1, and the magnitude of the values ​​represents the corresponding power weights.

[0047] In some embodiments, the charging pile charging control method further includes:

[0048] The expectation of the current charging power required by the charging pile is obtained, and the current load power required by the charging pile is obtained according to the percentage of the battery power of the vehicle corresponding to the current charging pile, and the first weight coefficient is determined according to the expectation and the current load required by the charging pile.

[0049] In a specific embodiment, the expected charging power E(x) of the current charging pile demand is obtained, that is, the charging power required by the current charging pile for the car, and a normal distribution diagram of the current charging pile demand charging power x and a curve of the current charging pile demand charging power x for time t are drawn according to the historical data of the current charging pile demand charging power x. Because the load of the charging pile on the photovoltaic power grid is determined by the charging power demand of the car, the load curve generated by the charging pile on the photovoltaic system in a day can be obtained through the above data. After the charging pile is based on the SOC of the car (the percentage of the car battery power, where 0 means that the car battery is out of power and 100 means that the car battery is fully charged), the time the car will stay and the load generated on the photovoltaic power grid during this period, that is, the current charging pile demand load power, can be estimated according to this load curve. According to the expected charging power E(x) of the current charging pile demand and the current charging pile demand load power P, the first weight coefficient k1 with the best efficiency can be determined, and k1 can be P / E(x).

[0050] In a specific embodiment, the second weight coefficient k2, the third weight coefficient k3 and the fourth weight coefficient k4 can be determined according to actual needs. As an example, when determining the second weight coefficient k2, because the factor corresponding to the second weight coefficient k2 is the total load power of the current photovoltaic power grid, it can be converted into the sum of the loads generated by each charging pile in the entire system on the photovoltaic power grid. The second weight coefficient k2 can be determined by steps similar to the above process, that is, obtaining the expectation of the total load power of the current photovoltaic power grid and the total load power required by the current photovoltaic power grid to obtain the second weight coefficient k2. Since the power that the transformer in the station can provide in the actual process is fixed, and the transformer needs to be responsible for the power supply of other electrical appliances in the station in addition to supplying power to the charging piles, the power used by these electrical appliances will change over time. Therefore, when determining the third weight coefficient k3, in addition to calculating the parameters (expectations) of the photovoltaic power generation power through the above process, it is also necessary to calculate the power on the ordinary power grid to obtain the user's power consumption expectations. According to these two expectations and the photovoltaic power generation load power, the value of the third weight coefficient k3 is determined. When determining the fourth weight coefficient k4, it is necessary to calculate the value of k4 by calculating the corresponding expectation and listing the normal distribution graph versus time curve through the switching times of the charging piles on the control matrix in the historical data.

[0051] In some embodiments, the charging pile charging control method further includes:

[0052] Acquire current weather data, current time data and current photovoltaic generator power data, and acquire the photovoltaic power generation prediction power according to the current weather data, the current time data, the current photovoltaic generator power data and a power prediction model; the power prediction model is trained according to historical weather data, historical time data, historical photovoltaic generator power data and an initial power prediction model.

[0053] In a specific embodiment, a large amount of historical weather data, historical time data and corresponding historical photovoltaic generator power data are obtained, and an initial power prediction model is trained based on the historical weather data, historical time data and historical photovoltaic generator power data to obtain a power prediction model.

[0054] In some embodiments, the initial power prediction model includes an input layer, a hidden layer, and an output layer.

[0055] In a specific embodiment, the initial power prediction model may be a neural network model.

[0056] In some embodiments, the hidden layer is used to extract the influence weights of the historical weather data and the historical time data on the historical photovoltaic generator power data.

[0057] In a specific embodiment, the input layer is used to receive raw input data, such as historical weather data, historical time data, etc., and pass it to the hidden layer. The hidden layer is used to calculate and extract the nonlinear characteristics and features of the input data. Specifically, the hidden layer is used to extract the influence weights of historical weather data and historical time data on historical photovoltaic generator power data. The output layer is used to receive the output data of the hidden layer and output the final prediction result.

[0058] In a specific embodiment, after obtaining the photovoltaic power generation prediction power according to the current weather data, the current time data, the current photovoltaic generator power data and the power prediction model, the power supply type arbitration value is obtained through the arbitration formula, thereby obtaining the determination result of the power supply type of the current charging pile, thereby improving the utilization efficiency of the photovoltaic power generation power. The actual photovoltaic power generation power corresponding to the current charging pile can be compared with the photovoltaic power generation prediction power to repeatedly optimize the power prediction model and improve the accuracy of the power prediction model.

[0059] S103: Control the charging switch of the current charging pile according to the determined power supply type.

[0060] In a specific embodiment, if it is determined that the power supply type of the current charging pile is photovoltaic power grid power supply, the charging switch (control switch) of the current charging pile is controlled to connect the current charging pile to the photovoltaic power grid, and the current charging pile uses the photovoltaic power grid to power the corresponding electric vehicle. If it is determined that the power supply type of the current charging pile is conventional power grid power supply, the charging switch of the current charging pile is controlled to connect the current charging pile to the conventional power grid, and the current charging pile uses the conventional power grid to power the corresponding electric vehicle.
