[0002] With the development and popularization of new energy vehicle technology, more and more new energy vehicles are beginning to appear on highways. In order to meet the charging needs of these new energy vehicles during long-distance driving, it is particularly important to rationally plan the charging equipment on highways.

[0003] However, existing charging equipment planning often lacks effective data support, resulting in unreasonable distribution of charging stations, which not only affects the travel experience of new energy vehicle drivers, but also causes waste of resources.

[0004] At present, the planning of charging equipment mainly relies on empirical estimates or simple statistical data, and lacks in-depth analysis of key factors such as the charging demand of new energy vehicles. In addition, with the advancement of new energy vehicle technology and the growth of market ownership, simple charging equipment planning methods are difficult to adapt to rapidly changing market demands.

[0005] In addition, the existing planning method for charging equipment is not comprehensive enough. It only plans certain sections of the highway, resulting in uneven distribution of charging equipment, which in turn reduces the convenience of choosing new energy for charging.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of a flow chart of the present invention. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, refer to Figure 1 , a power investment forecasting and analysis method based on data fusion, characterized by: including: Get the location of the toll station on a highway and divide the highway into sections. The density and location of charging equipment can be flexibly adjusted according to the different conditions of each section of the highway, making the layout of charging piles more reasonable and reducing the workload of planning. Each section of the highway after segmentation is recorded as a highway section, and the length of each highway section is obtained; The expressway section is specifically the expressway section between two adjacent expressway toll stations; Obtain information about expressway service areas on expressway sections; Count the number of new energy vehicles among the vehicles passing through the expressway toll station and obtain vehicle information of new energy vehicles; Determine whether the new energy vehicle needs to be charged while driving on the highway according to the vehicle information of the new energy vehicle obtained; If a new energy vehicle needs to be charged while driving on a highway, the location of the highway service area where the new energy vehicle is charged is obtained; Obtain the number of vehicles on the highway, calculate the percentage, and determine the investment and installation of charging equipment based on the percentage.

[0023] The method of obtaining the location of a toll station on a highway, dividing the highway into sections, recording each section of the highway as a highway section, and obtaining the length of each highway section is specifically as follows: Determine the starting point and end point of the expressway, obtain the number of toll stations on the expressway, and divide the expressway into sections according to the toll stations; dividing the expressway into sections according to toll stations can more accurately reflect the traffic flow and service area distribution, which is helpful for formulating more targeted charging equipment planning; Obtain the distance between the midpoint of each expressway section and the starting point of the expressway, and record the expressway sections in order from small to large as the first expressway section, the second expressway section, the third expressway section, and so on, the Nth expressway section according to the distance between the midpoint of each expressway section and the starting point of the expressway; The midpoint of the expressway section is specifically the midpoint of the expressway between two expressway toll stations at both ends of the expressway section; Get the lengths of the first expressway section, the second expressway section, the third expressway section, and so on, and record them as X 1 , X 2 , X 3 ...X N , the length of each highway section can be obtained to subsequently determine whether new energy vehicles need to be charged.

[0024] The step of obtaining the information of the expressway service area on the expressway section is as follows: Obtain the number of expressway service areas on the first expressway section, the second expressway section, the third expressway section, and so on the Nth expressway section; when planning, each expressway service area is within the planning scope to ensure that charging equipment covers a more comprehensive coverage and more fully meets the demand for new energy charging; The two toll stations of the first expressway section are respectively the No. 1 starting point toll station and the No. 1 terminal toll station, the two toll stations of the second expressway section are respectively the No. 2 starting point toll station and the No. 2 terminal toll station, the two toll stations of the third expressway section are respectively the No. 3 starting point toll station and the No. 3 terminal toll station... The two toll stations of the Nth expressway section are respectively the No. N starting point toll station and the N terminal toll station; The distance between the No. 1 starting point toll station and the starting point of the expressway is less than the distance between the No. 1 terminal toll station and the starting point of the expressway, the distance between the No. 2 starting point toll station and the starting point of the expressway is less than the distance between the No. 2 terminal toll station and the starting point of the expressway, the distance between the No. 3 starting point toll station and the starting point of the expressway is less than the distance between the No. 3 terminal toll station and the starting point of the expressway... The distance between the No. N starting point toll station and the starting point of the expressway is less than the distance between the No. N terminal toll station and the starting point of the expressway; Get the distance between each highway service area and the No. 1 starting point toll station on the first highway section, get the distance between each highway service area and the No. 2 starting point toll station on the second highway section, get the distance between each highway service area and the No. 3 starting point toll station on the third highway section... Get the distance between each highway service area and the No. N starting point toll station on the Nth highway section, get the distance between each highway service area and the starting point toll station on the highway section, combined with the length of each highway section, which is conducive to the subsequent judgment of whether new energy vehicles need to be charged, and the judgment of the location where new energy vehicles are charged.

[0025] The counting of the number of new energy vehicles among the vehicles passing through the expressway toll station and obtaining the new energy vehicle information of the new energy vehicles is specifically as follows: The number of new energy vehicles passing through starting point toll station No. 1, terminal toll station No. 1, starting point toll station No. 2, terminal toll station No. 2, starting point toll station No. 3, terminal toll station No. 3... starting point toll station No. N, terminal toll station N in the past year is counted respectively. The data of the past year can better capture the changes in the use trend of new energy vehicles, which is very important for planning charging facilities, and can also predict future demand, which helps to make more reasonable investment decisions; Obtain vehicle information of the counted new energy vehicles; The vehicle information includes the battery power of the new energy vehicle before it passes through the highway toll station to get on the highway, the battery power of the new energy vehicle before it passes through the highway toll station to get off the highway, the driving distance of the new energy vehicle on the highway, and the maximum distance that the new energy vehicle can travel when the battery is fully charged. By obtaining the above information, the new energy vehicle flow rate and the charging demand of different highway sections can be understood, so as to plan the layout and quantity of charging equipment in a targeted manner, accurately evaluate the charging demand, and ensure that the setting of charging equipment can meet actual needs.

[0026] The method of determining whether the new energy vehicle needs to be charged during driving on the highway according to the acquired vehicle information of the new energy vehicle is specifically as follows: S1. Obtain two toll stations that new energy vehicles pass through on the expressway; S2: The toll station closer to the starting point of the expressway is the first toll station, and the other toll station is the last toll station, that is, new energy vehicles enter the expressway through the first toll station and exit the expressway through the last toll station; S3. If there is no expressway toll station between the first-end toll station and the last-end toll station, the distance between the first-end toll station and the last-end toll station is the length of the expressway section between the first-end toll station and the last-end toll station. If a new energy vehicle enters the expressway at the fifth starting toll station and exits the expressway at the fifth terminal toll station, the first-end toll station is the fifth starting toll station and the last-end toll station is the fifth terminal toll station. At this time, there is no expressway toll station between the first-end toll station and the last-end toll station. The distance between the first-end toll station and the last-end toll station is the length of the fifth expressway section. S4. If there is a highway toll station between the head-end toll station and the tail-end toll station, the distance between the head-end toll station and the tail-end toll station is the sum of the distances of multiple highway sections between the head-end toll station and the tail-end toll station. If a new energy vehicle enters the highway at the No. 4 starting toll station and exits the highway at the No. 5 terminal toll station, the head-end toll station is the No. 4 starting toll station and the tail-end toll station is the No. 5 terminal toll station. At this time, there are the No. 4 terminal toll station and the No. 5 starting toll station between the head-end toll station and the tail-end toll station. The distance between the head-end toll station and the tail-end toll station is: the sum of the lengths of the fourth highway section and the fifth highway section. S5. Obtain the power of the new energy vehicle when it passes through the first-end toll station, and obtain the maximum distance that the new energy vehicle can travel with this power; S6. If the distance between the first toll station and the last toll station is greater than the maximum distance that the new energy vehicle can travel with this power, it means that the power of the new energy vehicle at this time cannot support the new energy vehicle to travel to the destination, so the new energy vehicle needs to be charged, and the new energy vehicle is marked as a charging vehicle; S7. If the distance between the first toll station and the last toll station is less than or equal to the maximum distance that the new energy vehicle can travel with this power, it means that the power of the new energy vehicle at this time can support the new energy vehicle to travel to the destination, so the new energy vehicle does not need to be charged, and the new energy vehicle will not be marked.

[0027] If the new energy vehicle needs to be charged while driving on the highway, the location of the highway service area where the new energy vehicle is charged is obtained, specifically: S8. Mark all expressway service areas between the first toll station and the last toll station, where the distance from the first toll station does not exceed the maximum driving distance of new energy vehicles at the current power level. New energy vehicles can be charged in these expressway service areas; S9. Select the expressway service area farthest from the first toll station among all marked expressway service areas and record it as the charging service area. This method can minimize unnecessary charging times, improve charging efficiency, and provide necessary support for new energy vehicles. S10. According to steps S1 to S9, the number of times each expressway service area is recorded as a charging service area in the expressway in the past year is obtained.

[0028] The method of obtaining the number of vehicles on the expressway, calculating the proportion, and determining the investment and installation of charging equipment according to the proportion is as follows: The total number of new energy vehicles traveling on the expressway in the past year is counted, and the total number of new energy vehicles traveling on the first expressway section, the second expressway section, the third expressway section, and the Nth expressway section in the past year are obtained respectively. The charging demand of each expressway section can be obtained according to the counted number of times; Calculate the ratio of the total number of new energy vehicles driving on the first expressway section, the second expressway section, the third expressway section, ... the Nth expressway section in the past year to the total number of new energy vehicles driving on the expressway in the past year; According to the ratio, the first expressway section, the second expressway section, the third expressway section, and the Nth expressway section are ranked in descending order. The larger the ratio, the higher the ranking, and the greater the demand for charging equipment. Obtain the target number of charging equipment installed on highways; Calculate the target number of charging equipment to be placed on each highway section, specifically: The target number of charging equipment installed on each expressway section is proportional to the ratio of the total number of new energy vehicles running on the first expressway section, the second expressway section, the third expressway section, ... the Nth expressway section in the past year to the total number of new energy vehicles running on the expressway in the past year; Calculate the target number of charging equipment to be placed in each expressway service area on each expressway section, specifically: The target number of charging equipment to be installed at each highway service area on each highway section is directly proportional to the ratio of the number of times each highway service area has been recorded as a charging service area in the past year to the total number of new energy vehicles traveling on the highway section in the past year. By sorting the highway sections based on the ratio of the total number of new energy vehicles traveling on each highway section to the total number of new energy vehicles traveling on the entire highway, we can more accurately assess the charging needs of different sections, ensure that charging facilities are set up where they are most needed, and improve the overall user experience.
