s110, the charging pile body obtains charging data of at least one charging gun, and the charging data are sent to a cloud server.
S210, the cloud server obtains at least one target charging gun model in the charging data at the charging starting moment.
The charging starting time refers to the time when the charging gun is inserted into a charging interface of a device to be charged (such as an electric vehicle) to start charging.
The model of the target charging gun is the model of the charging gun which is inserted into a charging interface of the equipment to be charged correspondingly, generally, each charging gun has a unique corresponding model, the model of the charging gun can be used for limiting the type of the equipment to be charged and also can be used for limiting the charging gun to execute direct current charging or alternating current charging, the model of the charging gun can be manually set by a charging user or can be model information configured by a charging gun manufacturer when the charging gun leaves a factory, and the model is not limited by the embodiment of the invention.

S220, the cloud server compares the model of the target charging gun with the model of a preset charging gun in a preset database.
The preset database refers to a database which is stored in the cloud server and used for inquiring charging rates, different charging guns of the charging pile and the charging rates of the charging guns can be stored in the preset database in advance, and searching and screening are facilitated.
The preset charging gun model refers to a charging gun model stored in a preset database, and each charging gun model corresponds to one charging rate one by one.
In the step, the cloud server checks a table of a preset database according to the model of the target charging gun for starting charging, and screens the preset charging gun model with the same model as the model of the target charging gun in the preset database.
And S230, the cloud server determines at least one real-time charging rate according to the comparison result, and the real-time charging rate corresponds to the target charging gun type number one to one.
In this step, the charging rate corresponding to the preset charging gun model that is the same as the target charging gun model in the preset database is determined as the real-time charging rate at the sampling time, and if a plurality of target charging gun models are identified, each target charging gun model corresponds to one real-time charging rate.
S240, the cloud server calculates the real-time charging cost of the charging gun in a segmented mode according to at least one real-time charging rate.
S130, the cloud server issues the real-time charging cost to the charging pile body and/or the charging gun so that the charging pile body and/or the charging gun can display the real-time charging cost.
Specifically, in the above steps S210 to S240, a specific implementation process of determining at least one real-time charging rate of a single charging gun by the cloud server according to the charging gun type number in the charging data is performed, the target charging gun type of the single charging gun for starting charging is identified and compared with the preset charging gun type in the preset database in the cloud server, so as to obtain the real-time charging rate of each charging gun, in the whole charging process, the charging rate of the single charging gun is fixed, it is ensured that different charging rates are adopted for different charging guns to charge under the condition that the charging pile body has a plurality of charging guns, and a preferential charging rate is set for the charging gun of a specific type, so that a user is encouraged to charge the charging equipment to be charged by using the specific charging type of the charging pile, and a green trip is realized.

s110, the charging pile body obtains charging data of at least one charging gun, and the charging data are sent to a cloud server.
S310, the cloud server obtains at least one target charging time period in the charging data at the charging sampling moment.
The target charging time period refers to a time period from a charging starting moment to a charging sampling moment in the process that the charging pile body performs charging on the device to be charged or makes a reservation for charging. For example, at the charging sampling time, the charging time may be in one target charging time period or in a plurality of target charging time periods, and the user may set the charging time according to actual needs, which is not limited.
In this step, the cloud server may analyze the charging time of a single charging gun at any charging sampling time, and extract at least one target charging time period that the single charging gun experiences from the charging start time to the charging sampling time.
S320, the cloud server compares the target charging time period with a preset charging time period in a preset database.
The preset charging time period refers to different charging time periods stored and set in a preset database, for example, 24 hours of a whole day can be divided into different preset charging time periods according to the power consumption, typically, the preset charging time period may include a power consumption peak time period and a power consumption valley time period, and each preset charging time period is correspondingly provided with a different charging rate.
In this step, the time interval of the preset charging period is greater than or equal to the time interval of the target charging period, and the time division point of the target charging period includes the time division point of the preset charging period. For example, one target charging period may be set every 4 hours, with time division points including 0 point, 4 points, … … 8 points, 12 points, … …, 20 points, and 24 points; a preset charging time period is set every 12 hours, the time division points of the preset charging time period can comprise 8 points and 20 points, wherein the electricity utilization valley time period from 8 points in the morning to 20 points in the evening is the electricity utilization valley time period, the charging rate can be 1.2 yuan/kilowatt hour, the electricity utilization peak time period from 20 points in the evening to 8 points in the next morning is the electricity utilization peak time period, and the charging rate can be 1.5 yuan/kilowatt hour.
In this step, the cloud server looks up the preset database according to the target charging time period, and screens the preset charging time period to which the target charging time period belongs and the charging rate corresponding to the preset charging time period in the preset database, so that the database data volume is reduced, and the data screening efficiency is improved.
S330, the cloud server determines at least one real-time charging rate according to the comparison result, and the real-time charging rates correspond to the target charging time periods one to one.
In this step, the cloud server obtains a target charging time period to which a single charging gun belongs from the charging starting time to the charging sampling time, and if the charging starting time to the charging sampling time spans two target charging time periods, the charging rates corresponding to the two target charging time periods are determined through a table look-up method.
S340, the cloud server calculates the real-time charging cost of the charging gun in a segmented mode according to at least one real-time charging rate.
S130, the cloud server issues the real-time charging cost to the charging pile body and/or the charging gun so that the charging pile body and/or the charging gun can display the real-time charging cost.
Specifically, in the steps S310 to S340, a specific implementation process of at least one real-time charging rate of a single charging gun is determined by the cloud server according to the charging time in the charging data, and all target charging time periods to which the single charging gun belongs from the charging start time to the charging sampling time are identified and compared with preset charging time periods in a preset database in the cloud server, so as to obtain a real-time charging rate of the charging gun in each target charging time period, so that it is ensured that the charging pile body realizes different charging rates in different charging time periods in the charging process of the device to be charged, rationalization of the charging rate is ensured, and meanwhile, a user can select a time period with a lower charging rate to charge the electric vehicle, so as to save power consumption.
For example, if the charging rate from 8 am to 20 am (i.e., the power consumption valley period) of the preset charging period is set to 1.2 yuan/kw, the charging rate from 20 am to 8 am (i.e., the power consumption peak period) of the preset charging period is set to 1.5 yuan/kw, and the charging time is set to 19 to 22 am, the target charging period determined by the cloud server includes a first target charging period in the power consumption valley period: 19 o 'clock to 20 o' clock, corresponding to a first real-time charging rate of 1.2 yuan/kilowatt-hour; and a second target charging time period at the peak electricity utilization period: and when the charging rate is charged when the corresponding second real-time charging rate is 1.5 yuan/kilowatt from 20 points to 22 points, charging the first target charging time period by adopting the first real-time charging rate, charging the second target charging time period by adopting the second real-time charging rate, and finally accumulating the sectional charging cost to obtain the real-time charging cost of the charging gun.
Optionally, fig. 4 is a flowchart of a charging method of a charging system according to an embodiment of the present invention, and on the basis of fig. 1, a specific implementation manner of obtaining a real-time charging rate in step S120 is shown, instead of limiting step S120.
As shown in fig. 4, the cloud server determines at least one real-time charging rate of the charging gun according to the charging data, and may further include the following steps:
s110, the charging pile body obtains charging data of at least one charging gun, and the charging data are sent to a cloud server.
S410, the cloud server obtains at least one target charging gun model in the charging data at the charging starting time and at least one target charging time period in the charging data at the charging sampling time.

S420, the cloud server compares the model of the target charging gun with the preset model of the charging gun in the preset database to obtain a first comparison result.
Specifically, the cloud server screens out the information of the charging guns with the same model as the target charging gun in a preset database according to the determined model of the target charging gun, and compares the information of the charging guns with the model of the target charging gun to obtain a first comparison result.

Optionally, fig. 5 is a flowchart of a charging method for a charging system according to an embodiment of the present invention, and on the basis of fig. 1, a specific implementation of calculating charging fee in a segmented manner is exemplarily shown.
As shown in fig. 5, the step of calculating the real-time charging fee of the charging gun according to at least one real-time charging rate may specifically include the following steps:
s110, the charging pile body obtains charging data of at least one charging gun, and the charging data are sent to a cloud server.
S510, the cloud server determines at least one real-time charging rate of the charging gun according to the charging data.
S520, the cloud server judges whether the real-time charging rate is changed or not in the charging process.
Specifically, in the charging process of the charging pile body to the electric vehicle, the cloud server can further judge whether the charging process is changed according to the determined real-time charging rate. For example, at the moment of charging is just started, if the cloud service determines a real-time charging rate, the cloud server records the value as S1, and after charging for a while, the cloud service determines a real-time charging rate again and compares the real-time charging rate with the previous value, and if the real-time charging rate changes, the cloud server records the value as S2, and the determination is sequentially performed according to the rule.
If the real-time charging rate changes, go to step S530; if the real-time charging rate changes, step S560 is executed.

Optionally, the obtaining of the sectional charging electric quantity of the charging gun at different real-time charging rates includes: acquiring first charging electric quantity of a current rate change node and second charging electric quantity of a previous rate change node, wherein a first real-time charging rate is set between the current rate change node and the previous rate change node; and calculating the first sectional charging electric quantity according to the difference value between the first charging electric quantity and the second charging electric quantity, wherein the first sectional charging electric quantity and the first real-time charging rate are used for calculating the first sectional charge.
Specifically, the cloud server records the charging amount of the charging gun and the real-time charging rate before and after the change at each node where the charging rate changes, calculates the segmented charging amount provided by the charging gun at the same real-time charging rate according to the difference between two adjacent charging amounts, and executes the subsequent step S550.
And S540, the cloud server calculates the sectional charge according to the real-time charging rate and the corresponding sectional charging electric quantity.
Specifically, the electricity consumption of the segment can be obtained by multiplying the real-time charging rate by the corresponding segment charging electric quantity.
For example, if the charging capacity of the current rate change node is defined as a first charging capacity Q1, the charging capacity recorded by the previous rate change node is defined as a second charging capacity Q2, and the real-time electric rate between the current rate change node and the previous rate change node is S2, the first segment charging capacity is defined as Q1-Q2, and the first segment charging capacity Q1-Q2 is multiplied by the real-time electric rate S2 before the current rate change to obtain a first segment charge, and the segment charges when the rate change occurs to each real-time charging rate are sequentially calculated by using the same method.

Specifically, if the real-time charging rate determined by the cloud server does not change in the whole charging process of the charging gun, the cloud server calculates the total charging electric quantity provided by the charging gun to the device to be charged from the charging starting time to the current sampling time, and the cloud server multiplies the total charging electric quantity by the initial charging rate recorded at the charging starting time to calculate the real-time charging cost at the fixed charging rate.
It should be noted that the fact that the real-time charging rate is not changed indicates that the charging gun is always within a preset charging time period corresponding to the same charging rate from the charging start time to the current sampling time.
S130, the cloud server issues the real-time charging cost to the charging pile body and/or the charging gun so that the charging pile body and/or the charging gun can display the real-time charging cost.
Specifically, the steps S510 to S560 are a specific implementation process of calculating the real-time charging fee of the charging gun in a segmented manner according to at least one real-time charging rate, and by judging whether the real-time charging rate changes during the charging process, if the charging rate changes, the segmented fee is calculated according to the changed charging rate and the segmented charging electric quantity corresponding to different real-time charging rates, so as to obtain the real-time charging fee; if the charging rate is not changed, the real-time charging fee is calculated according to the fixed charging rate and the total charging electric quantity, the reasonability of charging fee calculation is guaranteed, meanwhile, more charging choices are provided for the user, and the fee is saved.
Fig. 6 is a flowchart of a charging method of a charging system according to another embodiment of the present invention, where on the basis of fig. 1, after charging is completed, the charging method of the charging system further includes the following steps:
s610, the charging pile body sends a charging stopping instruction to the cloud server.
Specifically, the charging pile body detects the charge state of the equipment to be charged, whether charging is completed or not is judged according to the charge state, and if charging is completed, the charging pile body sends a charging stopping instruction to the cloud server.

Optionally, the terminal device may be an intelligent terminal device such as a smart phone, a tablet computer, and a notebook computer.
For example, the terminal device may identify a corresponding charging gun by scanning information such as a two-dimensional code on the charging gun, and receive a settlement bill sent by the cloud server.
Specifically, after receiving the charging stopping instruction, the cloud server stops calculating the charging fee, generates a settlement bill according to the real-time charging fee generated by the single charging gun from the charging starting time to the sampling time, then sends the settlement bill to the charging pile and/or the terminal device, displays corresponding settlement bill information in the terminal device, and can perform payment calculation after the user confirms that the settlement bill information is correct.
