The public charging station planning method of the disclosed embodiment will be described in detail below by way of fig. 2 to 5 based on the scenario described in fig. 1.

Referring to fig. 2, a flow chart of determining the number of charging piles at an electric bus station according to an embodiment of the present application may be implemented by a computer program, may be implemented by a single chip microcomputer, or may be run on a charging pile number determining device at the electric bus station. The computer program may be integrated in the application or may run as a stand-alone tool class application. In the embodiment of the present application, a server of an electric bus station is taken as an example, and specific steps of a method for determining the number of charging piles of the electric bus station are described in detail.

S201, obtaining average stop time and first average power consumption of a plurality of electric buses in a daily operation period of a first season, wherein the first season is a high-load season in one year.

The planning method in the application takes the year as a unit, the first season is a high-load season in one year, and when data acquisition is specifically carried out, the first season can be two seasons in summer and winter in one year, and it can be understood that the time of the two seasons in summer and winter can be determined according to the local actual condition and is determined by the battery consumption of the electric bus.

The average stop time is the average time of each electric bus staying in and out according to the bus schedule, is the accumulated time of the electric buses staying for a plurality of times, and can be also understood as the time of supplementing electricity for the electric buses in the in and out time in high load seasons.

The first average power consumption is an average power consumption per day obtained from the total power consumption of each electric bus in a high load season.

According to the embodiment disclosed by the application, the information of the average stop time and the first average power consumption is stored in the database of the electric bus, so that the server for determining the number of the charging piles can acquire corresponding information from the database.

In a preferred embodiment, the server is capable of processing the information entered by the user to obtain an average stop time and a first average power consumption by manually entering the information of the electric bus stop by the user.

In one implementation, a first proportion of a first high-load day in a first season and a second proportion of a first low-load day in the first season are obtained, wherein the first high-load day is a day when the power consumption in the first season is greater than a set threshold value, and the first low-load day is a day when the power consumption in the first season is less than or equal to the threshold value; calculating first average high-load power consumption corresponding to the first high-load day and first average low-load power consumption corresponding to the first low-load day; and carrying out weighted calculation on the first average high-load power consumption and the first average low-load power consumption to obtain first average power consumption of a plurality of electric buses in a daily operation period of a first season, wherein the weight of the first average high-load power consumption is a first proportion, and the weight of the first low-load power consumption is a second proportion.

Specifically, the first season is summer and winter, and because the use of the vehicle-mounted air conditioner is reduced due to overcast and rainy weather in summer, the power consumption requirement of the overcast and rainy weather day is reduced, and the temperature rises in winter, so that the performance of the battery returns to the maximum charge level of the normal temperature, and the power consumption requirement of the power consumption requirement is reduced. Therefore, for the operation day with smaller power consumption requirement in the first season, the direct calculation of the daily first average power consumption in the first season is not accurate enough.

The first high load day and the first low load day may be divided by a threshold value, which is determined by the power consumption requirements of each day in the high load season.

After the first high load day and the first low load day are divided, a first proportion of the first high load day in the first season and a second proportion of the first low load day in the first season are respectively determined, first average high load power consumption of each first high load day and first average low load power consumption of each first low load day are respectively calculated, the sum of the first proportion multiplied by the first average high load power consumption and the second proportion multiplied by the first average low load power consumption is obtained, namely the first average power consumption, and the average power consumption corresponding to different load days is respectively weighted and summed according to the date proportions of different load days, so that more accurate first average power consumption is obtained.

S202, calculating first charging power of a plurality of electric buses for charging at the average stop time based on the average stop time and the first average power consumption.

The first average power consumption can be understood as a daily average charging requirement of each electric bus in a high load season, and the average stop time can be understood as the maximum time length of each electric bus for supplementing electricity at the charging pile, so that the first charging power is the charging power which meets the daily average charging requirement in the average stop time.

And S203, acquiring the number of the first simultaneous standing vehicles in the daily operation period, and determining a first charging pile number range corresponding to different charging pile types based on the number of the first simultaneous standing vehicles and the first charging power.

The time of arrival and departure of the electric buses corresponding to each bus line is known, so that the first synchronous number of vehicles at the station can be obtained, and in an optional real-time mode, the maximum number of vehicles at the station can be determined as the first synchronous number of vehicles at the station by recording the number of vehicles at the station corresponding to each moment in the daily operation period.

For example, the first charging power is 600kW, the total number of the operated electric buses is 12, that is, the average charging power to each electric bus which is charged simultaneously is 50kW, the number of vehicles at the first time is 6, if the type a charging piles of one machine and two charging with 2 power charging interfaces of 100kW are adopted, 3 charging piles are required, if the type B charging piles of one machine and two charging with 2 power charging interfaces of 60kW are adopted, 5 charging piles are required, so the number of the first charging piles corresponding to the type a charging piles is 6, the number of the first charging piles corresponding to the type B charging piles is 5, and the number of the first charging piles forms the first charging pile number range.

In an alternative embodiment, the initial electric quantity, the residual electric quantity and the round-trip length of a plurality of electric buses for completing a single round-trip in a first season are obtained, and the unit power consumption required by the electric buses for completing the length of the longest round-trip in the first season is calculated; calculating the minimum charging power required by the single longest round trip based on the average parking time and the unit power consumption; obtaining the maximum charging current and the maximum charging voltage which can be born by a battery of the electric bus, and calculating the maximum charging power of the electric bus; and determining a first charging pile number range corresponding to different charging pile types based on the minimum charging power, the maximum charging power and the first synchronous on-station vehicle number.

In the embodiment of determining the range of the number of the first charging piles, by calculating the lowest unit power consumption required for each power replenishment, when the residual electric quantity of the electric buses is insufficient to support the single round trip, the longest requirement of the single round trip in a plurality of buses needs to be met, namely the minimum charging power is determined. The maximum charging power is defined according to the maximum charging power of the battery of the electric bus, specifically, the maximum charging current which can be born by the battery and the broad voltage input which can be born by the battery are obtained by referring to the charging standard of a battery manufacturer, and the maximum charging power of the electric bus can be determined.

And determining the minimum charging power which is an integer multiple by taking the minimum charging power as a basic charging power value and taking the maximum charging power as a constraint condition, determining the power of an optional charging interface, and selecting the number of first charging piles which meet the first simultaneous on-station vehicle number and the first charging power according to the power of the charging interface.

The charging interface power calculation model can be constructed based on the minimum charging power and the maximum charging power of the electric buses, the collected operation power consumption, line mileage, battery parameters and the number of vehicles at the station are input into the charging interface calculation model, and the charging interface power and the number range of the first charging piles corresponding to the charging piles of various types are output. For example, the minimum charging power of the electric bus is 40kW, and the maximum charging power is 130kW, so that the power of the charging interfaces can be selected to be 40kW, 80kW and 120kW, the corresponding charging piles can be selected to be different in power, and the number range of the first charging piles corresponding to the charging piles is obtained.

S204, obtaining second average power consumption of the plurality of electric buses in a daily operation period of a second season and average rest time of the plurality of electric buses in a daily non-operation period, wherein the second season is a low-load season in one year.

The second season is a low-load season in one year, which can be specifically explained as spring and autumn, and the influence of the environmental temperature on the operation of the electric bus and the use of the battery is small. The average power consumption per day in the second season of the second average power consumption is that the endurance mileage of the electric bus is generally longer than the line length of the daily operation line when the electric bus performs line planning and vehicle type selection, so that the electric bus only needs to perform power replenishment once per day under the condition of no other additional power consumption, and the power replenishment time is non-operation time.

The average trimming time of the daily non-operation period is the time length of the electric bus which can be subjected to power supply at the electric bus station after the electric bus completes daily line planning, and can be determined by reading the operation schedule of the electric bus station.

S205, calculating second charging power of the plurality of electric buses for charging in the average rest time based on the average rest time and the second average power consumption.

Because the overall power consumption level of the electric bus in the second season is lower than that in the first season, and the average trimming time for supplementing electricity is longer, the electric bus can be charged by adopting a charging pile with lower relative charging power.

In an alternative embodiment, a third proportion of a second high-load day in a second season and a fourth proportion of a second low-load day in the second season are obtained, wherein the second high-load day is a day when the power consumption in the second season is greater than a set threshold value, and the second low-load day is a day when the power consumption in the second season is less than or equal to the threshold value; calculating second average high-load power consumption corresponding to the second high-load day and second average low-load power consumption corresponding to the second low-load day; and carrying out weighted calculation on the second average high-load power consumption and the second average low-load power consumption to obtain second average power consumption of the plurality of electric buses in a daily operation period of a second season, wherein the weight of the second average high-load power consumption is a third proportion, and the weight of the second low-load power consumption is a fourth proportion.

The second high load day and the second low load day are divided by the set threshold in the second season in the same way as the first high load day and the first low load day are divided in the first season. Meanwhile, the weighting calculation of the second average power consumption is the same as the weighting calculation of the first average power consumption in step S201, and will not be described herein.
