For the embodiment of the application, in the peak time of centralized power utilization, the power supply and demand is tension, and the peak-valley electricity price is designed based on the electric energy time value, so that the system is an important mechanism arrangement for guiding the power users to cut peaks and fill valleys and ensuring the safe, stable and economic operation of the power system. The peak-valley electricity price divides a day into a peak, a flat section and a valley, and different electricity price levels are respectively formulated for each period so as to give full play to the electricity price signal function, and guide electric power users to use less electricity in the peak period and use more electricity in the valley period as much as possible, thereby ensuring the safe and stable operation of the electric power system, improving the overall utilization efficiency of the system and reducing the overall electricity cost of society.

Specifically, the relationship between the electricity price and the time period can be set by different areas or different power supply companies according to the actual electricity consumption condition, so that the time period is divided based on the relationship between the electricity price and the time period to obtain at least one valley electricity price time period, at least one flat electricity price time period and at least one peak electricity price time period, wherein the valley electricity price time period, the flat electricity price time period and the peak electricity price time period determined by different areas or different power supply companies may be different. For example, according to the relation between electricity prices and time periods performed by the Guangxi electric grid, the valley electricity price time period is 23:00 to 7:00 of the next day, the flat electricity price time period is 11:00 to 19:00, and the peak electricity price time period is 7:00 to 11:00,19:00 to 23:00.

And classifying the vehicles to be charged based on the charging power as a standard to obtain a collection of charging ports and the vehicles to be charged, wherein a plurality of charging port numbers and a plurality of vehicle to be charged numbers with the same power are stored in the collection of the charging ports and the vehicles to be charged, and the collection of the charging ports and the vehicles to be charged preliminarily achieves the purpose of classifying the charging ports and the vehicles to be charged according to the charging power. And then, predicting the charging duration based on the charging port and the residual electric quantity of each vehicle to be charged in the set of vehicles to be charged, and obtaining a first charging duration corresponding to each vehicle number to be charged. In the process of predicting the charging time length, multiple factors need to be comprehensively considered, wherein the multiple factors at least comprise: the charging power, the charging quantity and the ambient temperature may, of course, also include other factors, such as the aging condition of the bus battery and the automatic protection mechanism of the battery, which are not limited in the embodiments of the present application.

When the bus is charged, the charging arrangement of the bus is preferably placed in the valley electricity price period, and in this way, the electricity consumption force of the electricity consumption peak can be relieved, and the electricity charge expense of a bus company can be saved.

Further, valley electricity charging planning is performed based on the charging priority order, a plurality of charging port numbers in a set of charging ports and vehicles to be charged, a first charging duration and a valley electricity price period corresponding to each vehicle number to be charged, and a first charging time schedule is obtained, wherein the first charging time schedule comprises: the charging sequence of the target to-be-charged vehicle number corresponding to each charging port number and the corresponding first charging duration. Specifically, the vehicle to be charged is charged according to the charging priority sequence, in the valley electricity price period, valley electricity charging planning is performed according to a preset valley electricity distribution rule corresponding to the valley electricity price period based on a plurality of charging port numbers and first charging time periods corresponding to each vehicle number to be charged. The preset allocation rule has a plurality of modes, in one possible mode, vehicles to be charged are selected one by one according to the charging priority sequence, and then the preset allocation rule is determined based on the first charging time length corresponding to the number of the vehicles to be charged, the service condition of the number of the charging port and the earliest charging principle, wherein the earliest charging principle is to select the charging port capable of being charged earliest. In another implementation manner, a preset allocation rule is determined based on a first charging duration corresponding to a vehicle number to be charged, a service condition of a charging port number and an efficient charging principle, wherein the efficient charging principle is charging arrangement for performing charging arrangement that the first charging duration and the available charging duration are closest to each other based on the first charging duration corresponding to the vehicle number to be charged and the available charging duration of the charging port number. Of course, other preset allocation rules may be used, and the embodiments of the present application are not limited.

For the embodiment of the application, in the actual charging process, there may be more vehicles to be charged, but in the valley price stage, the number of charging ports cannot meet the charging requirements of all the vehicles to be charged, so that part of buses are not arranged to the corresponding charging ports in the first charging time arrangement. In order to be able to save the charge costs as much as possible, the vehicle to be charged, which cannot complete the charge arrangement in the valley price stage, is charged in the low price period in which the electricity price is low.

Specifically, there are many ways to determine whether the first charging schedule can complete the charging task for a plurality of vehicle numbers to be charged, for example, whether the first charging schedule completes the schedule for each vehicle number to be charged; whether the charging time of each of the vehicle numbers to be charged in the first charging time arrangement is in the valley electricity price phase or not, and the like. When the charging task cannot be completed, a plurality of unscheduled vehicle numbers which are not subjected to charging arrangement are firstly determined based on the first charging time arrangement, each unscheduled vehicle number is determined to correspond to the first charging time duration from first charging time durations corresponding to each vehicle number to be charged based on each unscheduled vehicle number, and then flat charging planning is conducted for a plurality of charging port numbers, each unscheduled vehicle number corresponds to the first charging time duration and the average price time period, so that the second charging time arrangement is obtained. The flat electricity charging plan is processed according to a flat electricity price distribution rule, the flat electricity price distribution rule has a plurality of modes, the same mode as a preset valley electricity distribution rule corresponding to a valley electricity price period can be adopted, and of course, the flat electricity charging plan can also be set by a user based on actual demands, and the embodiment of the application is not limited any more.

Step S106: analyzing whether the charging schedule is reasonable or not based on the initial charging schedule and the tomorrow shift information, wherein when the first charging schedule can complete the charging task, the first charging schedule is determined to be the initial charging schedule, and when the first charging schedule cannot complete the charging task, the first charging schedule and the second charging schedule are determined to be the initial charging schedule;

step S107: when the charging schedule is reasonable, the charging station is controlled to charge according to the initial charging schedule; when the charging schedule is not reasonable, the initial charging schedule is adjusted to obtain an adjusted charging schedule.

For the embodiment of the application, when the first charging time schedule and the second charging time schedule are determined, the arrangement order of the vehicles to be charged is determined only based on the tomorrow shift information, so that buses starting in the tomorrow are guaranteed to finish charging preferentially, and normal operation of bus companies is guaranteed to a certain extent. However, the initial charging schedule may not meet the charging requirement of the bus in all cases, and thus, after the initial charging schedule is determined, the rationality analysis of the charging schedule is performed by using the open day shift information, and various manners of rationality analysis are provided, which are not limited in the embodiments of the present application. For example, in the time dimension, based on the charging end time corresponding to each vehicle number to be charged in the initial charging time arrangement, and based on the tomorrow shift information, determining the earliest departure time corresponding to each vehicle number to be charged, and when the charging end time of the vehicle number to be charged is later than the earliest departure time, indicating that the charging arrangement is unreasonable; otherwise, the charging arrangement is indicated to be reasonable. Of course, other factors may be combined to perform the rationality analysis.

Furthermore, when the charging schedule is reasonable, the fact that the buses are charged according to the initial charging schedule is indicated, and the charging tasks of bus companies can be met, so that the charging station is controlled to charge according to the initial charging schedule. When the charging schedule is unreasonable, the fact that the charging of the vehicle to be charged is not completed in the next day working can influence the normal working of the bus is indicated, so that the initial charging schedule is adjusted, and the charging schedule is adjusted to ensure the normal operation of a bus company. The charging station is controlled to charge according to the charging time adjustment, and therefore all vehicles to be charged can be guaranteed to normally work on the next day. There are various ways of adjusting the initial charging schedule, and the embodiment of the present application is not limited, for example, each vehicle to be charged is charged according to the minimum charging duration, so as to ensure that each vehicle to be charged can complete charging before working on the next day.

Therefore, in the embodiment of the application, the charging time length is predicted based on the remaining electric quantity of each vehicle to be charged, so as to obtain the first charging time length corresponding to each vehicle number to be charged, and the charging priority sequences of a plurality of vehicle numbers to be charged are determined based on the tomorrow shift information, wherein the charging priority sequences can ensure that buses starting in the tomorrow can finish charging preferentially, and the normal operation of bus companies is ensured to a certain extent.

On the basis of ensuring normal operation, the application arranges the charging time of the bus in the valley electricity price period and the average electricity price period with lower cost as much as possible, thereby greatly saving the electricity charge expense of bus companies.

Further, in order to ensure that the vehicle to be charged works normally in the peak electricity price stage, the bus is prevented from being charged in the peak electricity price stage as much as possible, in the embodiment of the application, whether the charging schedule is reasonable is analyzed based on the initial charging schedule and the tomorrow shift information, and when the charging schedule is unreasonable, the initial charging schedule is adjusted to obtain the adjusted charging schedule, which comprises the following steps: step SA (not shown) to step SD (not shown), wherein:

The tomorrow shift information includes: the bus departure time and the vehicle number, so that the earliest departure time corresponding to each vehicle number to be charged can be determined based on the open-day shift information, wherein the vehicle number and the vehicle number to be charged in the open-day shift information have a one-to-one correspondence. Furthermore, charging arrangement reasonable analysis is carried out based on the charging end time and the earliest departure time corresponding to each vehicle number to be charged, and when at least one vehicle number to be charged exists and the charging end time is later than the earliest departure time, the charging arrangement is determined to be unreasonable; otherwise, the charging arrangement is determined to be reasonable.

In order to save the charge expense of a bus company, the bus is charged in a valley electricity price period and a flat electricity price period as much as possible, so when the charge arrangement is unreasonable, the minimum charge duration prediction is carried out based on the peak electricity price period, the open day shift information and the remaining quantity of the vehicle to be charged, so as to obtain the minimum charge duration corresponding to each vehicle number to be charged, wherein the vehicle to be charged is controlled to charge for the minimum charge duration, the normal work of the vehicle to be charged in the peak electricity price period can be ensured, and the charging of the bus in the peak electricity price period is avoided as much as possible, wherein the peak electricity price period refers to: peak electricity price period in the mid-am phase of each day. Specifically, the departure times corresponding to each vehicle number to be charged are determined based on the peak electricity price time period and the open day shift information, the loop power consumption required by one trip of the vehicle number to be charged is estimated based on the historical power consumption condition corresponding to each vehicle number to be charged, then the minimum electric quantity required by each vehicle number to be charged is determined based on the departure times and the loop power consumption, and further, the minimum charging duration prediction is performed based on the minimum electric quantity corresponding to each vehicle number to be charged and the residual electric quantity of the vehicle to be charged, so as to obtain the minimum charging duration corresponding to each vehicle number to be charged, wherein various factors can be considered when the minimum charging duration prediction is performed, and the method at least comprises the following steps: the method for predicting the minimum charging duration according to various information such as the charging speed of the number of the vehicle to be charged, the charging environment temperature and the like is not limited.

Step SD: and adjusting the initial charging time schedule based on the charging time length adjustment rule and the lowest charging time length to obtain an adjusted charging time schedule, wherein the adjusted charging time length of each number of vehicles to be charged in the adjusted charging time schedule is not smaller than the corresponding lowest charging time length.

For the embodiment of the application, the minimum charging time corresponding to each number of the vehicle to be charged is ensured to normally work in the peak electricity price period. Therefore, the charging time schedule is adjusted based on the charging time length adjustment rule, so as to obtain the adjusted charging time schedule, wherein the charging time length adjustment rule is preset and stored in the electronic equipment, and the charging time length adjustment rule has a plurality of modes. In one case, the charging duration adjustment rule is preset with a reduction step length of the charging duration, and the first charging duration corresponding to each vehicle number to be charged is adjusted based on the reduction step length until the charging schedule is reasonable, so as to obtain the adjusted charging schedule. In another case, a reduction ratio of the charging duration is preset in the charging duration adjustment rule, and the first charging duration corresponding to each number of the vehicles to be charged is adjusted based on the reduction ratio until the charging schedule is reasonable, so that the charging schedule is adjusted.

Specifically, in one case, a step of reducing the charging duration is preset in the charging duration adjustment rule, so that the first charging duration corresponding to each vehicle number to be charged in the initial charging time schedule is adjusted based on the step of reducing the charging duration, that is, the first charging duration minus the step of reducing is taken as the adjusted charging duration corresponding to the vehicle number to be charged, the adjusted charging duration corresponding to each vehicle number to be charged is taken as the first charging duration, the processing operations of steps S104 to S106 are executed, and when the target charging schedule obtained based on the adjusted charging duration is reasonable, the target charging schedule is determined to be the adjusted charging schedule; when the target charging time schedule obtained by adjusting the charging time length is unreasonable, subtracting the reduction step length of the charging time length from the adjustment charging step length, and then adjusting the charging time schedule based on the adjusted charging time length until the charging schedule is reasonable. It should be noted that, in the process of gradually decreasing the step length for the charging time period, it is necessary to ensure that the adjusted charging time period of each of the vehicle numbers to be charged in the adjusted charging time schedule is not less than the corresponding minimum charging time period. In another case, a reduction ratio of the charging duration is preset in the charging duration adjustment rule, that is, a reduction ratio corresponding to different charging durations is determined for each charging duration, for example, the charging duration is 4 hours, and the reduction ratio is 15%; the charging duration is 3 hours, the reduction ratio is 10%, etc. Furthermore, the adjustment is performed according to the reduction ratio of the charging duration and the first charging duration corresponding to each vehicle number to be charged, and the steps of the cyclic adjustment are similar to those in the first case until the charging arrangement is reasonable, so that the embodiment of the application is not repeated for the sake of simplicity of discussion.

Therefore, in the embodiment of the application, the charging arrangement is reasonably analyzed based on the charging end time and the earliest departure time corresponding to each vehicle number to be charged, and when the charging arrangement is unreasonable, the lowest charging duration prediction is performed based on the peak electricity price period, the open day shift information and the remaining electric quantity of the vehicle to be charged to obtain the lowest charging duration corresponding to each vehicle number to be charged, wherein the vehicle to be charged is controlled to charge for the lowest charging duration, so that the normal work of the vehicle to be charged in the peak electricity price stage can be ensured, and the charging of the bus in the peak electricity price period can be avoided as much as possible. Furthermore, the initial charging schedule is adjusted based on the charging duration adjustment rule and the minimum charging duration, resulting in an adjusted charging schedule.

Further, in order to utilize the valley electricity price period of each charging port to charge the vehicle to a great extent, and avoid the valley electricity price period of the charging port to be divided into more and less periods, in the embodiment of the present application, valley electricity charging planning is performed based on the charging priority order, a plurality of charging port numbers in a set of the charging port and the vehicle to be charged, a first charging duration corresponding to each vehicle to be charged number, and the valley electricity price period, so as to obtain a first charging schedule, including: step S1041 (not shown in the figure) to step S1046 (not shown in the figure), wherein:

Step S1041: acquiring initial charging time length corresponding to each charging port number, wherein the initial charging time length is the same as the time length of the valley electricity price period;

step S1042: selecting a first vehicle number to be charged based on the charging priority sequence, and randomly selecting a first target charging port number from a plurality of charging port numbers for the first vehicle number to be charged;

step S1043: and carrying out charging distribution and charging duration update based on a first charging duration corresponding to the first vehicle number to be charged and an initial charging duration corresponding to each charging port number to obtain a chargeable duration corresponding to the first target charging port number.

For the embodiment of the application, in valley electricity charging planning, namely, in the process of charging the vehicle to be charged in the valley electricity price period, the vehicle to be charged is arranged in a mode of being closest to the charging time length when the vehicle to be charged and the charging ports are distributed, and in this way, the vehicle to be charged can be charged by using the valley electricity price period of each charging port to a great extent, so that the situation that the valley electricity price period of the charging ports is divided into more and more small time periods is avoided, and the small time periods cannot meet the charging requirements of the unassigned vehicle to be charged is caused.

Specifically, an initial charging duration corresponding to each charging port number is obtained, wherein the initial charging duration is the same as the duration of the valley electricity price period, and further, a first vehicle number to be charged is selected from the charging priority order to carry out charging port number allocation. When the first vehicle number to be charged is allocated, since the initial charging duration corresponding to each charging port number is the same, one charging port number is randomly selected from a plurality of charging port numbers and is recorded as a first target charging port number. Then, charging distribution and charging duration update are carried out based on a first charging duration corresponding to a first vehicle number to be charged and an initial charging duration corresponding to each charging port number, and a chargeable duration corresponding to a first target charging port number is obtained, wherein the charging distribution and charging duration update operations are as follows: and determining a corresponding relation between the number of the vehicle to be charged and the target charging port, and recording the difference value of the initial charging time length minus the first charging time length as the chargeable time length corresponding to the number of the first target charging port, wherein the number of other vehicles to be charged keeps the initial charging time length unchanged.

Step S1044: selecting a second vehicle number to be charged based on the charging priority sequence, and calculating a difference value based on the chargeable duration corresponding to each charging port number and the first charging duration corresponding to the second vehicle number to be charged to obtain a duration difference value corresponding to each charging port number, wherein the duration difference value is a positive number;

Step S1045: selecting a second target charging port number corresponding to the minimum time length difference value, performing charging distribution and charging time length update based on a first charging time length corresponding to the second vehicle number to be charged, a chargeable time length corresponding to the second target charging port number and the second target charging port number, and determining the chargeable time length corresponding to the second target charging port number.

For the embodiment of the application, the second number of the vehicle to be charged is selected based on the charging priority order, and the vehicle to be charged is arranged in a mode of 'closest to the charging time length', so that the charging port number closest to the first charging time length corresponding to the second number of the vehicle to be charged needs to be determined. Therefore, based on the chargeable duration corresponding to each charging port number and the first charging duration corresponding to the second vehicle number to be charged, a duration difference corresponding to each charging port number is obtained, wherein the chargeable duration is the charging duration which can be allocated by the charging port number in the valley price stage, if the vehicle to be charged is not allocated by the charging port number, the chargeable duration is the initial charging duration, the magnitude of the duration difference represents the proximity degree of the charging duration, and the duration difference is required to be guaranteed to be a positive number, namely, the current duration difference is a negative number, and the fact that the remaining charging duration of the charging port number in the valley price stage is insufficient to meet the charging requirement of the second vehicle number to be charged is indicated. And then, selecting the charging port number with the smallest time length difference value, and recording the charging port number as a second target charging port number of a second vehicle number to be charged, and further, carrying out charging distribution and charging time length update based on the first charging time length corresponding to the second vehicle number to be charged, the chargeable time length corresponding to the second target charging port number and the second target charging port number to obtain the chargeable time length corresponding to the second target charging port number. The operations of the charge allocation of the first to-be-charged vehicle number and the second to-be-charged vehicle number and the charge duration update are the same, and for simplicity of discussion, they will not be discussed here.

Step S1046: selecting the vehicle numbers to be charged one by one as a second vehicle number to be charged according to the charging priority sequence, and repeatedly executing difference calculation based on the chargeable duration corresponding to each charging port number and the first charging duration corresponding to the second vehicle number to be charged to obtain a duration difference value corresponding to each charging port number, wherein the duration difference value is a positive number; selecting a second target charging port number corresponding to the minimum time length difference value, carrying out charging distribution and charging time length update based on a first charging time length corresponding to the second vehicle number to be charged, a chargeable time length corresponding to the second target charging port number and the second target charging port number, and determining a chargeable time length corresponding to the second target charging port number until the time length difference value is negative, or finishing charging arrangement of the last vehicle number to be charged, so as to obtain a first charging time arrangement.

For the embodiment of the application, the charging arrangement operation same as that of the second to-be-charged vehicle number is executed aiming at each to-be-charged vehicle number so as to finish the charging arrangement of each to-be-charged vehicle number, thus, the to-be-charged vehicle numbers are selected one by one according to the charging priority order and recorded as the second to-be-charged vehicle number, and the difference value calculation is repeatedly executed on the basis of the chargeable duration corresponding to each charging port number and the first charging duration corresponding to the second to-be-charged vehicle number, so as to obtain a duration difference value corresponding to each charging port number, wherein the duration difference value is a positive number; selecting a second target charging port number corresponding to the minimum time length difference value, carrying out charging distribution and charging time length update based on a first charging time length corresponding to the second vehicle number to be charged, a chargeable time length corresponding to the second target charging port number and the second target charging port number, and determining the chargeable time length corresponding to the second target charging port number until the time length difference value is negative, or finishing charging arrangement of the last vehicle number to be charged. When the difference value of the time length is a negative number, the residual charging time length of each charging port number cannot meet the charging requirement of the second vehicle number to be charged. Because each vehicle number to be charged determines the corresponding relation between the vehicle number to be charged and the charging port number when the charging arrangement is performed, the first charging time arrangement is determined based on the corresponding relation between the vehicle number to be charged and the charging port number and the first charging time period corresponding to each vehicle number to be charged, wherein the first charging time arrangement comprises: the charging sequence of each vehicle number to be charged corresponding to each charging port number and the corresponding first charging duration. The processing flows of step S1041 to step S1046 are as shown in fig. 2.

In order to be able to more clearly discuss the operation procedures of steps S1041 to S1046, the embodiment of the present application shows, by way of example, the arrangement procedure of arranging the vehicle to be charged in the "closest charge time period" manner and the arrangement procedure of arranging the vehicle to be charged in the conventional manner, as shown in fig. 3 and 4. Fig. 3 is a schematic diagram of the operation procedure of the vehicle to be charged arrangement in the manner of "closest charging time period", and it can be clearly seen in fig. 3 that the first charging time period corresponding to each number of the vehicle to be charged is allocated, and the charging port 4 is idle for one hour. Fig. 4 is a conventional procedure for arranging vehicles to be charged, that is, a first-come first-charge mode, in which charging port is preferably idle for charging, and it can be clearly seen in fig. 4 that the first charging period corresponding to the last vehicle number to be charged is not allocated yet, however, the charging port 2, the charging port 3 and the charging port 4 all have idle time. Therefore, the vehicle to be charged is arranged in a mode closest to the charging time, the valley electricity price time period of each charging port can be utilized to charge the vehicle to a great extent, the situation that the valley electricity price time period of the charging port is divided into more small time periods, which are scattered is avoided, and the small time periods cannot meet the charging requirement of the unassigned vehicle to be charged.

It can be seen that, in the embodiment of the present application, a first to-be-charged vehicle number is selected based on a charging priority sequence, a first target charging port number is randomly selected from a plurality of charging port numbers for the first to-be-charged vehicle number, and charging allocation and charging duration update are performed based on an initial charging duration corresponding to each charging port number and a first charging duration corresponding to the first to-be-charged vehicle number, so as to obtain a chargeable duration corresponding to the first target charging port number. And selecting a second vehicle number to be charged, and calculating the difference between the chargeable duration corresponding to each charging port number and the first charging duration corresponding to the second vehicle number to be charged. And then, carrying out charge distribution and charge duration update based on the first charge duration corresponding to the second vehicle number to be charged, the chargeable duration corresponding to the second target charge port number and the second target charge port number. And then, selecting the number of the vehicle to be charged as the number of the second vehicle to be charged one by one according to the charging priority sequence, and repeatedly executing the charging arrangement processing until the time length difference is negative, or completing the charging arrangement of the last number of the vehicle to be charged, and finally obtaining the first charging time arrangement. The vehicle to be charged is arranged in a mode closest to the charging time, the valley electricity price time period of each charging port can be utilized to charge the vehicle to a great extent, the situation that the valley electricity price time period of the charging port is divided into more small time periods, which are scattered is avoided, and further, the small time periods cannot meet the charging requirements of the unassigned vehicle to be charged.

Further, in order to ensure that the target bus can not be abnormal due to insufficient electric quantity in the next trip, and reduce the charge expense of the bus company as much as possible, in the embodiment of the application, the method further comprises the following steps:

judging whether the current residual electric quantity is smaller than an electric quantity threshold value corresponding to the target bus, and determining a current electricity price stage corresponding to the current period when the current residual electric quantity is smaller than the electric quantity threshold value corresponding to the target bus, wherein the electricity price stage comprises: valley electricity price period, flat electricity price period, and peak electricity price period;

In the embodiment of the present application, the embodiment of the present step is a process of whether power replenishment is required during operation of the bus, and thus the execution sequence of steps S101 to S107 is not limited. The number of vehicles to be charged in the charging station is far greater than the number of charging ports, so that each bus can be ensured to normally go out in the initial operation stage, and each bus can be charged as much as possible during centralized charging. However, various emergency situations may be encountered in the operation process of the bus, for example, severe weather conditions, abnormal conditions of preset lines and abnormal increase of passenger flow, which may cause insufficient battery power of the bus to support the whole-day operation of the bus. In order to avoid the situation that passengers are forced to change the bus due to insufficient electric quantity when the bus runs along a preset route, the application judges whether the current residual electric quantity of the target bus is smaller than the electric quantity threshold corresponding to the target bus after the bus runs along the preset route for one time, wherein the electric quantity threshold is used for ensuring that the target bus can complete the running of the next preset route no matter under any working condition, and each target bus has the electric quantity threshold corresponding to the target bus. Preferably, the power threshold is determined by considering various factors including at least: the historical electricity consumption condition of each trip of the target bus, the time period condition of departure of the next day and the environmental condition of the current day can also comprise other various factors, and the embodiment of the application is not limited any more.

Furthermore, when the current residual capacity of the target bus is not smaller than the corresponding electric quantity threshold value, the current residual capacity of the target bus is indicated to be capable of meeting the requirement of the next trip of the target bus, and therefore it is determined that the target bus does not need to be supplemented with electricity midway temporarily. When the current residual electric quantity of the target bus is smaller than the corresponding electric quantity threshold value, the current residual electric quantity of the target bus is indicated to be incapable of meeting the requirement of the next trip of the target bus, and therefore the target bus is controlled to carry out power supplementing so as to ensure that the target bus cannot be abnormal due to insufficient electric quantity in the next trip of the target bus. The power supply is to ensure that the target bus can operate normally without filling the target bus, so that it is extremely important to determine the power supply quantity of the target bus in the process of controlling the power supply of the target bus.

Specifically, when the current electricity price stage corresponding to the current period is obtained when the current electricity price stage is smaller than the electricity quantity threshold corresponding to the target bus, since the target bus needs a period of time for electricity replenishment, if the current time is used for determining the electricity price stage, the situation that the electricity price stage is determined to be abnormal exists, for example, the current time is 6:55, the valley electricity price period is 23:00 to 7:00 of the next day, the peak electricity price stage is 7:00 to 11:00, and if the current electricity price stage is determined based on the current time, the current electricity price stage is the valley electricity price period, however, the charging of the target bus is generally over 0.5 hours, so that most of the charging periods are the peak electricity price stages. Thus, when the current electricity price stage is determined by using the current time period, the current time period occupies more electricity price stages and is determined as the current electricity price stage, wherein the current time period is a time period taking the current time as a starting point and taking a time period step as a span, and preferably, the time period step is 0.5 hour. Then, based on the relation between the current electricity price stage, the electricity price and the time period and the scheduling information, determining the supplementary electricity quantity of the target bus, namely, based on the relation between the current electricity price stage, the electricity price and the time period, determining the electricity price stage distribution condition until the operation is finished, judging whether the current electricity price stage is the lowest electricity price stage in the electricity price stage distribution condition, if so, determining the electricity quantity required by the target bus until the operation is finished based on the scheduling information, and recording the electricity quantity as the supplementary electricity quantity of the target bus; if not, determining the electric quantity required by the target bus in the current electricity price stage based on the scheduling information and the current electricity price stage, and recording the electric quantity as the supplementary electric quantity of the target bus. The application synthesizes the current electricity price stage factors when determining the supplementary electricity quantity, so that the buses can be charged more in the low electricity price stage and less in the high electricity price stage to a certain extent, and the charging expense of bus companies is reduced as much as possible.

To more clearly discuss the process of determining the amount of electricity to be replenished, embodiments of the present application are illustrated, in one case, based on the relationship between the current electricity price phase, the electricity price and the period, the electricity price phase distribution condition until the operation is completed is determined as follows: the peak electricity price stage, the flat electricity price stage and the peak electricity price stage, so that the current electricity price stage (peak electricity price stage) is not the lowest electricity price stage in the electricity price stage distribution condition, and the electricity quantity required by the normal operation of the target bus in the peak electricity price stage is determined based on the peak electricity price stage and the scheduling information and is recorded as the supplementary electricity quantity of the target bus. In another case, based on the current electricity price phase, the relation of electricity price and time period, the electricity price phase distribution condition until the operation is finished is determined as follows: and the flat electricity price stage and the peak electricity price stage, so that the current electricity price stage (flat electricity price stage) is the electricity price stage with the lowest electricity charge in the electricity price stage distribution condition, and the electric quantity required by the target bus until the normal operation is finished is determined based on the scheduling information and is recorded as the supplementary electric quantity of the target bus.

Therefore, in the embodiment of the application, after the bus runs for one time according to the preset route, whether the current residual electric quantity is smaller than the electric quantity threshold corresponding to the target bus is judged, if so, the current residual electric quantity of the target bus cannot meet the requirement of the next running of the target bus, so that the supplementary electric quantity of the target bus is determined based on the relation among the current electric quantity stage, the electric quantity and the time period and the scheduling information. Furthermore, the charging station is controlled to supplement electricity to the target bus based on the electricity supplement quantity, so that the target bus can be guaranteed not to be abnormal due to insufficient electricity in the next running.

Further, in order to make the electric quantity threshold highly match with the actual consumption situation of the target bus, in the embodiment of the present application, the method for determining the electric quantity threshold corresponding to the target bus includes:

determining a target period of next running of the target bus based on scheduling information, acquiring congestion conditions and passenger flow corresponding to a preset route of the target period, and calculating an electric quantity fluctuation value based on the congestion conditions and the passenger flow;

and comprehensively determining the electric quantity threshold value corresponding to the target bus based on the average electric quantity consumption and the electric quantity fluctuation value.

For the embodiment of the application, as the buses of different routes, different operation time periods and other factors can influence the electric quantity consumed by the buses in one circle according to the preset routes, the electric quantity threshold corresponding to the target buses is personalized, and therefore, when the electric quantity threshold corresponding to the target buses is determined, the average electric quantity consumed, the crowding condition and the passenger flow quantity corresponding to the next running target time period are synthesized, and the electric quantity threshold is determined so as to enable the electric quantity threshold to be highly matched with the actual consumption condition of the target buses.

Specifically, based on the historical power consumption condition of the target bus, the average power consumption of the target bus for one trip according to the preset route is determined, for example, in one case, the historical power consumption condition is the loop power consumption of the target bus for each trip, and then average calculation is performed based on all the loop power consumption, and the calculation result is determined to be the average power consumption. In another case, the historical electricity consumption condition is the total daily electricity consumption of the target bus in one day, division calculation is performed based on the total daily electricity consumption and the number of times of departure, and the calculation result is determined to be the average electricity consumption. Further, a target period of next trip of the target bus is determined based on the scheduling information, and congestion conditions and passenger flows corresponding to the target period of the preset route are determined, wherein the corresponding relations between the target period and the congestion conditions and between the target period and the passenger flows are stored in the electronic device in advance, so that the congestion conditions and the passenger flows corresponding to the target period can be determined rapidly and accurately according to the target period. Since the average power consumption does not deeply consider the individuation of the preset route in the target period, the congestion condition and the passenger flow corresponding to the average power consumption can be regarded as standard conditions, that is, the congestion condition and the passenger flow in one day in the preset route are quantified, and average processing is performed based on the respective quantified data to obtain the standard conditions. Then, based on the congestion condition and the passenger flow volume of the target period, calculating an electric quantity fluctuation value, further, based on the congestion condition, the passenger flow volume and the standard condition of the target period, comparing to determine a congestion phase difference value and a passenger flow volume phase difference value, and based on the congestion phase difference value and the passenger flow volume phase difference value and the corresponding fluctuation relation, determining the electric quantity fluctuation value, wherein the congestion phase difference value, the passenger flow volume phase difference value and the electric quantity fluctuation value can be positive, negative or zero. And finally, adding and settling based on the average consumed electric quantity and the electric quantity fluctuation value, and determining an electric quantity threshold value corresponding to the target bus.

It can be seen that, in the embodiment of the present application, when determining the electricity quantity threshold corresponding to the target bus, the average electricity consumption, the congestion condition and the passenger flow corresponding to the target period of the next trip are synthesized, and the electricity quantity threshold is determined, so that the electricity quantity threshold is highly matched with the actual consumption condition of the target bus.

Further, in order to improve accuracy of the first charging duration, in the embodiment of the present application, the predicting the charging duration based on the remaining power of each vehicle to be charged to obtain the first charging duration corresponding to each number of the vehicle to be charged includes:

and predicting the charging time length based on the current environment temperature, the historical power consumption corresponding to each number of the vehicle to be charged and the residual power of the vehicle to be charged, and obtaining a first charging time length corresponding to each number of the vehicle to be charged.

For the embodiment of the application, when the bus is charged, the charging time is influenced by the charging power and the charging electric quantity, and the charging time is influenced by the ambient temperature to a certain extent in the charging process, so that the influence of the ambient temperature on the charging time is deeply considered when the charging time is predicted. Specifically, difference value calculation is performed based on the historical power consumption corresponding to each number of the vehicle to be charged and the remaining power quantity of the vehicle to be charged, and the charging total power quantity corresponding to each number of the vehicle to be charged is determined, wherein the historical power consumption is the sum of the power quantities required by the vehicle to be charged to travel for one day. Further, a rough charging time length is calculated based on the total charging electric quantity and the charging power, and a rough charging time length is obtained, wherein the rough charging time length is a time length required to be consumed when the vehicle to be charged is charged in a normal environment temperature range, and the normal environment temperature range is preferably 15-40 ℃. Further, the influence condition of the current environmental temperature on the charging period is determined based on the current environmental temperature and the temperature influence relation, wherein the temperature influence relation is determined by the related technicians based on a large amount of experimental data, for example, when the environmental temperature is in the range of 0 ℃ to minus 5 ℃, the charging period is increased by 66% compared with the normal environment. And finally, predicting the charging time length based on the rough charging time length and the influence condition to obtain a first charging time length corresponding to each vehicle number to be charged. For example, the rough charging period is 180 minutes, the ambient temperature is minus 3 ℃, and thus the charging period is increased by 66% compared to that in the normal environment, so the first charging period is calculated to be 298.8 minutes, that is, the first charging period=180×1+0.66=298.8 minutes.

Therefore, in the embodiment of the application, the environmental temperature also affects the charging duration to a certain extent in the charging process, so that the influence of the environmental temperature on the charging duration is deeply considered when the charging duration is predicted. The charging duration prediction is performed based on the current environment temperature, the historical power consumption corresponding to each number of the vehicle to be charged and the remaining power of the vehicle to be charged, so that the first charging duration corresponding to each number of the vehicle to be charged is obtained, and the accuracy of the first charging duration is improved.

Further, in order to avoid the situation that the charging danger occurs due to the power mismatch to a certain extent, in the embodiment of the present application, before obtaining the target remaining power of the to-be-charged vehicle corresponding to each of the plurality of target to-be-charged vehicle numbers in the set of the charging port and the to-be-charged vehicle, the method further includes:

vehicle power distribution is carried out based on charging port power and vehicle charging power, and a plurality of groups of charging ports and sets of vehicles to be charged are obtained, wherein each group of charging ports and sets of vehicles to be charged comprise: a plurality of charging port numbers and a plurality of vehicle numbers to be charged with the same power.

For the embodiment of the application, the bus charging station generally carries out unified charging for buses with multiple lines, multiple vehicle types and a large number, and the charging power required by charging is different due to different vehicle types, so that the power supply station is provided with charging ports with different charging powers in order to meet the charging requirements of all buses. For the safety of bus charging, the charging port and the vehicle to be charged can be classified based on power, and the vehicle to be charged is charged by using the charging port matched with the power, so that the situation of charging danger caused by power mismatch is avoided to a certain extent. Therefore, the application carries out power matching based on the charging port power in the charging station information and the vehicle charging power in the vehicle information to be charged, so as to obtain a plurality of groups of charging ports and sets of vehicles to be charged, and the charging ports and the sets of vehicles to be charged are respectively provided with charging port numbers and vehicle numbers to be charged with the same power.

Therefore, in the embodiment of the application, the vehicle power distribution is performed based on the charging port power and the vehicle charging power to obtain a set of a plurality of groups of charging ports and vehicles to be charged, the charging ports and the vehicles to be charged are classified based on the power for the safety of bus charging, and the vehicles to be charged are charged by using the charging ports matched with the power, so that the situation of charging danger caused by power mismatch is avoided to a certain extent.
