The invention aims to provide a dispatching method and a dispatching system for an automatic charging pile of an electric automobile, so as to shorten invalid charging time and improve the utilization efficiency of the charging time.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 is a flowchart of a scheduling method of an automatic charging pile of an electric vehicle according to the present invention, and as shown in fig. 1, the scheduling method of the automatic charging pile of the electric vehicle includes:
step 100: the expected vehicle taking time, the target charging amount, the charging parameter, the current parking space number and the current battery capacity of the electric vehicle of the user are obtained. The charge parameter is the amount of electricity charged to the battery per unit time.
Step 101: and determining the charging time of the electric vehicle of the user according to the target charging amount, the charging parameters and the current battery electric quantity, and recording as a first charging time.
Step 102: and determining the expected parking time of the electric vehicle of the user according to the expected vehicle taking time and the current moment.
Step 103: and determining whether a conflict exists between the expected vehicle taking time of the user electric vehicle and the target charging amount of the user electric vehicle according to the relation between the expected parking time and the charging time.
Step 104: if there is a conflict, the user is prompted to modify an expected pickup time of the user electric vehicle or a target charge amount of the user electric vehicle.
Step 105: and if the conflict does not exist, acquiring the charging time of all the electric vehicles to be charged in the same automatic charging pile and the parking space numbers of all the electric vehicles to be charged. And recording the charging time of all the electric vehicles to be charged as a second charging time.
Step 106: and determining a charging sequence according to the current parking space number, the parking space numbers of all the electric automobiles to be charged, the first charging time and the second charging time.
In the step, an iteration strategy is mainly adopted to determine a charging sequence, and the specific process is as follows:
and setting unit charging time delta t, and only charging one electric automobile by the automatic charging pile in each unit charging time. Subtracting the current time from the expected vehicle taking time of the vehicle to be charged in the nth parking space to obtain the expected parking time, and recording the expected parking time as tn. D is the time required for charging the vehicle in the nth parking spacen. Note TnFor the number of expected parking times, DnIn order to increase the amount of time required for charging,
Figure BDA0002736078410000081
and taking the redundant time caused by rounding as the moving and butting time allowance and the charging time allowance of the automatic charging pile.
After passing through the operations of step 100 to step 105, Dn≤TnIf it is always true, then record Tij＝Tj-Ti. Wherein T ish、Ti、TjAnd TkFour adjacent expected parking times.
If D isj≤TijThe timing may be as shown in part (a) of FIG. 2, at ThTo TjIn all unit charging time, first distribute DiCharging the ith vehicle in unit charging time and redistributing the charging time to the ith vehiclejCharging the jth vehicle for the unit charging time. Namely, the charging time requirement of the ith vehicle is met in advance by charging, and then the charging time requirement of the jth vehicle is completed. Recording the interval from the charging completion of the jth vehicle to the vehicle taking time of the user as D'xAnd allocating the vehicle to be charged in the x number parking space with the highest charging priority, and if D'x≥DxAnd after the charging of the vehicle to be charged in the parking space x is finished, the charging is carried out according to the charging priority.
If D isj＞Tij，Di+Dj≤Ti+TjThe charging schedule is shown in part (b) of fig. 2.
If D isj＞Tij，Di+Dj＞Ti+TjIs T'j＝Ts+Di+Dj，T′jThe converted time is the predicted vehicle taking time corrected after the second verification of the vehicle user in the jth parking space, and the corrected predicted vehicle taking time is informed to the user. The charging schedule is shown in part (c) of fig. 2.
To this end, the first iteration is completed.
After charging time arrangement of the vehicles to be charged in the ith and jth parking spaces is finished, setting Tx＝Tj. If present T'jThen set Tx＝T′j. Set up Dx＝Di+DjThen D isx≤TxThis is always true. Then, iteration is carried out according to the iteration strategy steps until the last expected parking time is TfAs shown in part (d) of fig. 2.
To this end, TfCharging parking spaces of charging piles within unit charging time are determined, and charging is generatedAnd (4) a sequence of (A) and (B). Updating T when new vehicles enter the charging parking space and upload datan、DnAnd sequencing and restarting the iterative computation.
According to the calculation of the iterative strategy, the result is a charging time sequence, and the data in the sequence represent the charging sequence and the charging time arrangement of the automatic charging gun to the vehicle to be charged on each charging parking space in the next time. The automatic charging gun executes the charging tasks according to the sequence, and then the scheduling of the automatic charging gun by the scheduling method can be realized. The formed charging time sequence is a row of one-dimensional arrays, and the ith element n [ i ] of the charging time sequence represents the parking space where the vehicle is located and is automatically charged by the charging pile within the ith unit charging time.
Wherein, the definition of the charging priority is as follows:
if D 'is present'xAnd then D'xThe charging order in time is determined by the charging priority.
At Ti，TjWithin a time (T)i，TjThere is no other expected number of car taking times in the middle), if the charging of the car to be charged in the j-th parking space is completed, the charging time arrangement of the remaining time depends on the charging priority.
Setting the charging sequence weight of the vehicle to be charged in the x-th parking space as qxIf the vehicle enters the charging point parking point for the a-th vehicle among all the uncharged vehicles and leaves the charging point as the b-th vehicle after finishing charging according to the expected vehicle taking time, then
Figure BDA0002736078410000091
qxThe smaller the charging priority. If the charging sequence weights of the two vehicles are the same, the smaller vehicle has a higher charging priority.
In addition, under the condition that the unit charging time is set to be larger, all charging time sequences can be obtained by an enumeration method directly, and the optimal charging time sequence is screened out.
Step 107: an actual charging time for the user electric vehicle to charge to the target charge amount is determined according to the charging sequence.
Step 108: and judging whether the actual charging time is earlier than the expected vehicle taking time or not to obtain a judgment result.
Step 109: and if so, completing the charging of the electric vehicles to be charged and the user electric vehicles according to the charging sequence.
Step 110: if not, reminding the user to modify the expected vehicle taking time of the user electric vehicle or the target charging quantity of the user electric vehicle.
The expected pickup time, the target charge amount, the charging parameter, the current parking space number and the current battery level of the user electric vehicle adopted in the step 100 are all input by the user through a mobile phone.
And if the user refuses to modify the expected vehicle taking time of the user electric vehicle or the target charging amount of the user electric vehicle, sending the charging requirement of the user to other automatic charging piles within a specific distance range from the automatic charging piles, and respectively determining the actual charging time of the user electric vehicle in the other automatic charging piles for the user to select. The specific value of the specific distance range from the automatic charging pile is artificially determined according to the number and the distance of the actually laid automatic charging piles.
The following provides a specific embodiment to further explain the scheme of the present invention, and in the specific embodiment of the present invention, a user uses a user APP implanted in a mobile phone to implement the scheduling method provided by the present invention as an example for explanation, and in the specific application, the scheme of the present invention is also applicable to control programs implanted in other hardware structures.
Consider the following application scenario: the charging parking spot is provided with n charging parking spaces (n is more than or equal to 2), one automatic charging pile can charge the electric automobile parked on any charging parking space, and the automatic charging pile can only provide charging service for one vehicle at the same time.
An App (application) corresponding to the automatic charging pile is installed in advance in a mobile phone of an electric vehicle user, and information such as a vehicle type of the electric vehicle is input in advance by the user.
When a user parks the vehicle at a certain charging parking space, the vehicle is communicatedAnd inputting expected car taking time, target charging amount, selected charging mode and current parking space through App. The mobile phone and the vehicle are communicated through Bluetooth to acquire the current vehicle battery capacity SOCS. App combines pre-recorded charging parameters n (n is the amount of battery charge capable of being charged per hour in the charging mode selected by the vehicle owner) and target charging amount SOC (state of charge)FTo obtain the time required for charging
Figure BDA0002736078410000101
(unit: hour), the expected parking time T is obtained by subtracting the current time from the expected vehicle taking time2. If T2＜T1And if so, the expected car taking time conflicts with the target charging amount, and the user is reminded to modify the expected car taking time and the target charging amount. And if no conflict exists, uploading expected parking time, charging required time and vehicle parking space data to the automatic charging pile server. The above is the first check, and the expected vehicle taking time uploaded by the user and the target charging amount are ensured not to conflict with each other, so that the method is real and effective.
And after the automatic charging pile server receives the data, updating the data of the vehicles to be charged at the parking spot. Since the parking spot has n parking spaces, there may be a case where the charging schedule of the vehicle conflicts with the charging schedules of other vehicles. And planning the automatic charging pile charging time sequence through an iterative strategy to obtain the actual time required for charging the vehicle of the user to the target charging amount at the current charging stop point, and checking whether the actual time is earlier than the expected vehicle taking time or not, wherein the charging requirement of the vehicle owner can be met if the actual time is earlier than the expected vehicle taking time. If the charging time sequence can be met, the charging time sequence is handed to the automatic charging pile to be executed. If the target electric quantity is not met, the time required by the vehicle to charge to the target electric quantity and the chargeable amount of the expected vehicle taking time are calculated, and the vehicle is communicated with a mobile phone of a user to ask the user to modify the expected vehicle taking time or the target charged amount. If the proposed expected pickup time is not acceptable to the user (i.e., the user refuses to modify), the charging stop point cannot meet the user's demand. The charging requirement of the user is sent to the nearby charging parking spots, and the expected vehicle taking time of the requirement at each other charging parking spot is calculated for the user to select. And if the user finishes the modification confirmation, the automatic charging pile executes the charging time sequence to finish the charging of each vehicle to be charged.
