for each electric vehicle 12, the information transceiver system 11 is configured to transmit power supply side information and vehicle state information corresponding to the current time period to the electric vehicle 12;
the electric automobile 12 is configured to determine, according to the information on the power supply side and the automobile state information, a charging action corresponding to a minimum charging cost of the electric automobile on the basis of meeting a charging demand of the electric automobile in a remaining parking time period, and use the charging action as a charging action of the electric automobile in a current time period, calculate a charging cost corresponding to the electric automobile in the current time period according to the charging action, and determine a charging total cost corresponding to the electric automobile in the current time period according to a charging total cost corresponding to the electric automobile in a previous time period and a charging cost corresponding to the electric automobile in the current time period, where the charging action is one of: charging and non-charging.
In one embodiment of the present application, the power supply side and the electric vehicle may be communicatively connected to the information transmission and reception system, so that the power supply side transmits the power supply side information in real time, and the electric vehicle transmits the vehicle state information to the information transmission and reception system in real time. The information transceiving system can be understood as an information collecting, processing and forwarding system.
The modes in which the power supply side and the electric vehicle can be communicatively connected to the information transmission and reception system include, but are not limited to, wired data communication and wireless data communication, wherein the wireless data communication includes, but is not limited to, 4G network communication and 5G network communication.

For example, as shown in fig. 2, based on the communication between the power supply side 21 and the electric vehicle 12 and the information transmission and reception system 11, the power supply side 21 may transmit the power supply side 21 information to the information transmission and reception system 11, and the electric vehicle 12 may transmit the vehicle state information to the information transmission and reception system 11, and the information transmission and reception system 11 may receive the power supply side 21 information and the vehicle state information, and may transmit the power supply side 21 information and the vehicle state information to the electric vehicle 12.
The electric vehicle 12 receives the information of the power supply side 21 and the vehicle status information sent by the information transceiving system 11, determines a charging action corresponding to the minimum charging cost of the electric vehicle on the basis of meeting the charging demand of the electric vehicle in the remaining parking time period according to the information of the power supply side 21 and the vehicle status information, takes the charging action as the charging action of the electric vehicle in the current time period, calculates the charging cost of the electric vehicle in the current time period according to the charging action, and determines the total charging cost of the electric vehicle in the current time period according to the total charging cost of the electric vehicle in the previous time period and the charging cost of the electric vehicle in the current time period.
Specifically, the electric vehicle 12 may determine the state indicating information corresponding to the electric vehicle 12 in the current time period according to the information of the power supply side 21 and the vehicle state information, then determine the charging policy corresponding to the minimum charging cost of the electric vehicle on the basis of satisfying the charging demand of the electric vehicle in the remaining parking time period according to the state indicating information, and further determine the corresponding charging action according to the charging policy.
That is, after receiving the information on the power supply side 21 and the vehicle state information sent by the information transceiving system 11, the electric vehicle 12 may determine the state indicating information corresponding to the current time period, may detect the charging amount of the electric vehicle in the remaining parking time period, and compare the charging amount in the remaining parking time period with the charging amount threshold in the remaining parking time period, and if the charging amount is greater than the charging amount threshold in the remaining parking time period, it may be understood that the charging demand of the electric vehicle in the remaining parking time period is satisfied, and therefore, the charging policy corresponding to the lowest charging cost of the electric vehicle may be taken as the corresponding charging action.
For example, the state representation information may include a remaining required charging period of the electric vehicle, a remaining parking period, and ranking information of remaining amounts of electricity of the electric vehicles among the plurality of electric vehicles.
In an embodiment of the present application, before executing the step of taking the charging policy corresponding to the minimum charging cost of the electric vehicle as the corresponding charging action, the electric vehicle 12 may first determine whether the remaining required charging time period is equal to zero, and if the remaining required charging time period is equal to a non-zero value, execute the step of determining, according to the information on the power supply side and the vehicle state information, the charging action corresponding to the minimum charging cost of the electric vehicle on the basis of meeting the charging demand of the electric vehicle within the remaining parking time period.
It should be noted that, when the remaining required charging time period is equal to zero, it is understood that the electric vehicle will leave. And when the residual required charging time is equal to a non-zero value, the charging condition of the electric automobile is considered.

For example, the power supply end 13 is a charging pile, it is determined that the charging action corresponding to the current time period is no charging, and when the charging pile obtains that the charging action corresponding to the current time period is no charging, the charging pile does not charge the electric vehicle in the current time period, which can be understood that the charging cost corresponding to the electric vehicle in the current time period is zero.
It should be noted that the current corresponding charging action may affect the remaining power of the electric vehicle in the next time period, so in an embodiment of the present application, when determining the corresponding charging action, the electric vehicle may further determine, according to the charging action in the current time period, vehicle state information corresponding to the electric vehicle 12 in the next time period, and upload the vehicle state information corresponding to the electric vehicle 12 in the next time period to the information transceiver system 11, so that the information transceiver system 11 receives the vehicle state information and optimizes the charging policy of the electric vehicle.

and respectively representing the residual electric quantity, the residual required charging time length and the residual parking time length of the electric automobile i in the t period, and ranking of the residual electric quantity in all the electric automobiles. In the above state variables, wt，

Wherein Δ t represents the length of the unit time period, and the remaining required charging time of the electric vehicle in the next time period is:
the remaining required charging time of the electric automobile in the next period is as follows:
when the remaining charging period is 0, it indicates that the electric vehicle will leave, and the charging condition of the vehicle will not be considered in the next period.
In the embodiment of the application, after the automobile state information corresponding to the electric automobile in the next time period is determined, the charging cost in the current time period is calculated according to each electric automobile
For example, by optimizing the charging strategy of each electric vehicle, the goal of minimizing the discounted total cost of the electric vehicle is achieved, namely:
where γ is the discount factor, ptRepresents the total cost of charging over the period t,
