[0019] Figure 1 A schematic diagram of the structure of an intelligent parking and charging system for electric vehicles provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0020] 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.

[0021] Based on this, an embodiment of the present invention provides a three-dimensional electric vehicle intelligent parking and charging system, which systematically plans the spatial structure and charging mode of the charging station, carries out three-dimensional construction, and intelligent design, so as to realize automatic parking, unmanned charging, intelligent sorting, and appointment pick-up of electric vehicle charging stations.

[0022] To facilitate understanding of this embodiment, a three-dimensional electric vehicle intelligent parking and charging system disclosed in an embodiment of the present invention is first introduced in detail, including:

[0023] The automated parking platform includes a robotic arm, a conveyor belt, a three-dimensional multi-story parking area, a vehicle entry channel, and a vehicle exit channel. The robotic arm includes an image recognition device, an infrared sensing system, a power system, and a motion control system.

[0024] The mechanical arm and the conveyor belt are used to transport the electric vehicle to the three-dimensional multi-storey parking area to wait for charging, the vehicle entry channel is used to transport the electric vehicle to the charging area, and the vehicle exit channel is used to transport the electric vehicle to the vehicle pick-up area;

[0025] The vehicle model automatic identification system includes a Bluetooth module, an infrared module, an image recognition module, a network module, a laser positioning system, and a charging port positioning system, which are used to identify the vehicle model, form a three-dimensional model of the vehicle, and locate the charging area and the charging port;

[0026] The visual car pickup reservation system includes a display screen, a network module, an operation console, and a payment system, and is used for reserving car pickup and paying fees.

[0027] In this embodiment, the automated parking platform is composed of a multi-axis intelligent charging robotic arm, a conveyor belt, a three-dimensional multi-story parking area, an entry channel, and an exit channel. The user can leave by parking the vehicle in the entry area. The multi-axis intelligent charging robotic arm and the conveyor belt will transport the electric vehicle to the three-dimensional multi-story parking area to wait for charging. The three-dimensional multi-story parking area adopts a multi-layer ring design, which is divided into three rings: inner, middle and outer. The center of the inner ring is the main charging pile. Electric vehicles in the outer and middle rings can enter the inner ring through the entry channel. The space utilization rate is extremely high. When charging, the vehicle is transported to the predetermined charging area by a vehicle moving robot. When the user picks up the vehicle, the vehicle is transported to the pick-up area through the exit channel. The entire process is automatically controlled and unattended.

[0028] In this embodiment, the main charging pile includes a charging pile body, sixteen high-speed fast charging heads, a power monitoring system, and an electricity fee calculation module. The high-speed charging head is equipped with a highly flexible charging cable, which is controlled by a multi-axis intelligent robotic arm. It passes through the space above the vehicle storage area and moves to the charging port of the charging vehicle to perform charging operations. The multi-axis intelligent charging robotic arm can not only insert the charging head into the charging port, but also has a suction cup and magnetic tentacles to open the charging port cover of the electric vehicle. The power monitoring system can monitor the charging progress of the car in real time. The electricity fee metering module adopts the peak and valley electricity price mode to calculate the charging cost of the electric vehicle.

[0029] In this embodiment, the vehicle model automatic identification system includes a Bluetooth module, an infrared module, an image recognition module, a network module, a laser positioning system, and a charging port positioning system. After the vehicle enters the vehicle entry area, the image recognition module identifies the vehicle model and transmits its three-dimensional model to the background processor. The vehicle moving robot can then accurately move it to the designated position in the charging area so that the multi-axis intelligent charging robotic arm can insert the charging head.

[0030] In this embodiment, the multi-axis intelligent charging robot arm includes an image recognition device, an infrared sensing system, a power system, and a motion control system. The automatic parking platform parks the vehicle in the charging area and accurately positions it. The charging port is located according to the data uploaded by the automatic vehicle model recognition system. The image recognition module and the charging port positioning system are used as backup. The multi-axis intelligent charging robot arm is used to insert the charging head into the charging port. After waiting for charging to be completed, the charging head is pulled out to complete charging.

[0031] In this embodiment, the visual reservation pick-up system includes a display screen, a network module, an operation console, and a payment system. A large-screen touch operation console is set up in the pick-up area, where users can pick up the car. It is also equipped with a mobile app, and users can make reservations and pay for the car on their mobile phones. The visual reservation pick-up system uses digital twin technology to convert the spatial structure of the charging station into a 3D model, and displays the total number of currently charging cars and the estimated charging time in real time. When the user picks up the car, the visual reservation pick-up system can display the current location of the vehicle and the scheduled pick-up point.

[0032] In this embodiment, the number of vehicles M that a charging station can carry is determined based on the time required to charge the current mainstream vehicle models and the off-peak electricity price of the power grid.

[0033] Specific load capacity

[0034] Where T is the off-peak electricity price time stipulated by the power grid, and t is the average charging time of common vehicles on the market. According to research, the average charging time of common electric vehicles on the market is 0.5h, while the current peak-valley electricity price policy has an off-peak electricity price time of 23:00 to 7:00 the next day. In summary, the maximum number of vehicles that a charging station can carry is 256.

[0035] In this embodiment, the comprehensive charging coefficient Z is obtained by comprehensively analyzing the battery capacity, loss degree, charging speed, and remaining power of the electric vehicle, Z=Rd+Rs+Rc+Re,

[0036] in

[0037] Rd = total capacity of user batteries / standard battery capacity of charging station. The standard battery capacity of a general charging station is 100 kwh (adjustable according to actual needs). If Rd is greater than 1, take 1;

[0038] Rs = user's maximum charging capacity / user's total battery capacity, if Rs is greater than 1, take 1;

[0039] Rc = user battery charging power / charging station standard charging power. The standard charging power of a general charging station is 100kw (adjustable according to actual needs). If Rc is greater than 1, take 1;

[0040] Re = user's remaining power / user's total battery capacity. If Re is greater than 1, it is set to 1.

[0041] In the app, car owners can choose from multiple charging options and make reservations for car pick-up times. The participation coefficient C can be obtained by the degree to which car owners choose to participate in the peak and valley regulation of the virtual power plant.

[0042] Cy = ∫ (available peak load time / grid peak load time) * user output power + ∫ (available valley load time / grid valley load time) * user charging power

[0043] Cb=30kwh, C=Cy / Cb, C is greater than 3, so take 3.

[0044] Combining the comprehensive consideration coefficient Z and the participation coefficient C, the charging ranking index P is obtained.

[0045] P=Z+δC, where δ∈[0,x), x is the peak shaving and valley filling coefficient of the local power grid, the ratio of the peak and valley values ​​of the power grid yesterday, and can be set to 0 according to the grid dispatching requirements.

[0046] The cars are parked in the inner ring, middle ring, and outer ring respectively. The inner ring is for electric vehicles with a P value less than 4, and priority is given to charging electric vehicles that do not participate in demand response and do not consider peak and valley electricity charges. The middle ring is for electric vehicles with a P value between 4-8, and the outer ring is for electric vehicles with a P value greater than 8.

[0047] This embodiment can also achieve the following effects:

[0048] 1. Exchange information with the State Grid Corporation of China to obtain the demand for peak-shaving and valley-filling, and estimate today's peak-shaving and valley-filling capacity through the vehicle reservation system, and submit today's peak-shaving and valley-filling workload;

[0049] 2. Optimize the entry and exit routes of electric vehicles to achieve the shortest and fastest moving paths.

[0050] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
