If a new charging device needs to be connected into the charging pile for charging, the charging power distributed to the charging pile can be properly increased so as to meet the requirements of users. Then, the charging rate and the charging demand of the charging equipment which is connected with the target charging pile and is being charged can be obtained, and the charging completion time of the charging equipment which is being charged is calculated according to the charging rate and the charging demand; and then combining the estimated arrival time of the user with the charging completion time to determine whether a chargeable interface exists for charging the user when the user arrives at the target charging pile; if a chargeable interface exists for charging a user, more power can be distributed to the target charging pile through a server, and a previous reference regulation strategy is determined as the target regulation strategy; if the chargeable interface is not available for charging by the user, the reference regulation and control strategy is properly adjusted according to the charging power of the target charging pile, the power of the target charging pile distributed to the charging equipment being charged and the priority of the equipment, so as to obtain the target regulation and control strategy, for example, the charging power of the target charging equipment with charging completion time later than the expected arrival time of the user can be properly reduced, and the charging power of the equipment with priority higher than that of the equipment to be charged can be increased, so that the chargeable interface is vacated in a shorter time for charging by the user.
It can be seen that in this example, the charging pile is better regulated and controlled in combination with the charging priority of the analysis device, the expected arrival time and the charging power of the target charging pile, so that the user can quickly charge when arriving.
In one possible embodiment, said adjusting said reference regulation strategy according to said charging priority, said first expected arrival time and said first power parameter, to obtain a target regulation strategy comprises: acquiring a charging rate and a charging demand of a target charging device, wherein the target charging device is a charging device which is connected with the target charging pile and is being charged; determining a charging completion time of the target charging device according to the charging rate and the charging demand; determining whether a chargeable interface exists when the equipment to be charged reaches the target charging pile according to the estimated arrival time and the charging completion time; if yes, determining the reference regulation strategy as the target regulation strategy; if the charging priority is not found, determining a second power parameter of a reference charging device according to the charging priority and the first power parameter, wherein the reference charging device is a target charging device with the charging completion time being later than the expected arrival time, and the second power parameter is used for indicating the charging power distributed by the target charging pile for the reference charging device; and adjusting the reference regulation strategy according to the second power parameter to obtain a target regulation strategy.

After the priorities of the target charging pile and the equipment to be charged are determined, calculating the ending time of the equipment being charged in the target charging pile, and judging whether the target charging pile has an interface for charging the equipment to be charged after the equipment to be charged reaches the target charging pile. If the interface is charged, the power of the target charging pile can be properly increased; if no interface is charged, the power allocated to the charging device with low priority can be reduced and the power allocated to the charging device with high priority can be allocated more according to the priority of the charging device, so that the queuing time of the device to be charged can be reduced. After the charging pile is detected to be connected with the charging gun, charging information of the charging equipment can be obtained, and the charging information is stored for subsequent charging progress tracking.
In this example, it is determined whether the target charging pile has an interface for charging by the user, and the target charging pile is regulated and controlled under the condition that the interface is not provided, so that the user can charge in a shorter time.
In one possible embodiment, the determining a target charging pile from the at least one charging pile according to the charging demand information and the driving parameter includes: determining a reference charging pile set according to the demand information and the driving parameter information, wherein the reference charging pile set comprises a plurality of reference charging piles, and the reference charging piles are charging piles in the at least one charging pile; acquiring the charging condition of each reference charging pile in the plurality of reference charging piles, wherein the charging condition is used for indicating the charging completion time of charging equipment corresponding to each charging interface in the reference charging pile; determining a second estimated arrival time of the equipment to be charged to each reference charging pile according to the driving parameters; determining whether an alternative charging pile exists according to the second expected arrival time, wherein the alternative charging pile is a reference charging pile with at least one charging interface in the reference charging pile set, and the charging completion time corresponding to the charging interface is earlier than the second expected arrival time; if yes, determining the alternative charging pile as the target charging pile; if the second estimated arrival time does not exist, determining the waiting time of each reference charging pile according to the second estimated arrival time and the charging completion time; determining the distance between each reference charging pile and the equipment to be charged according to the position information; and determining a target charging pile from the reference charging pile set according to the distance and the waiting time.
And comparing the charging completion time with the time of the user reaching the alternative charging pile, and judging whether the charging pile in the alternative charging pile can rapidly provide charging service. If the waiting time is short, the waiting time of the alternative charging piles is calculated, the distance of the charging piles corresponding to the waiting time is calculated according to the position information of the user, and the target charging pile is determined from the alternative charging piles under the conditions that the waiting time is short and the distance is short.
Therefore, in this example, in combination with the charging condition of the nearby charging piles and the time analysis of the user reaching each charging pile, the charging pile which has the least time and can be rapidly charged is selected as the target charging pile, so as to shorten the waiting time of the user.
In one possible embodiment, the lifting time is determined according to the lifting time provided by the target object or according to the historical lifting time of the device to be charged.
If the user does not provide the time for carrying the vehicle, determining that the time for carrying the vehicle when the user charges the charging device in the current period is the time for carrying the vehicle when the user charges the charging device in the current period. For example, after the user in the district goes home after coming off duty, the device to be charged is charged, but no vehicle lifting time is provided, at this time, the historical vehicle lifting time of the user is queried, and if the user is queried that the vehicle lifting time of the user in the district is 8 points in the morning for many times, the vehicle lifting time of the user in the district is determined to be 8 points in the morning.
In this example, when the user does not provide the lift time, the historical lift time may be selected as the current lift time for reference.
