[0028] The basic components of a DC charging pile include: a power unit, a control unit, a metering unit, a charging interface, a power supply interface, and a human-machine interface. The power unit refers to the DC charging module, and the control unit is the charging pile controller. As a system integration product, the structural design of a DC charging pile, besides the DC charging module and the charging pile controller, is a key aspect of the overall pile reliability design. Therefore, the design structure of the multimodal self-organizing implicit intelligent charging station project is divided into three parts: above ground, underground, and connection. The above-ground part consists of an adjustable support integrated component 5, a charging gun 4, a shielding component 7, and a display screen 6. The charging gun 4 is typically made of conductive material, featuring wear resistance and good conductivity. The display screen 6 provides users with necessary information display and an operating interface. The display screen 6 internally houses the charging pile intelligent control module, which has display, input, emergency stop, alarm, card swiping, and wireless communication functions. The input module allows flexible selection of charging amount or charging amount, and the alarm module... The system features fault alarms and alarms for charging completion without disconnecting the charging gun. The display function shows the charging amount, remaining battery power, and remaining charging time, helping users understand the charging progress and status, and improving user control over the charging process. The input function allows users to flexibly select the charging amount or amount, meeting different user needs and preferences, and enhancing the personalization and flexibility of the charging process. The emergency stop function allows users to immediately interrupt the charging process in emergencies, ensuring the safety of the charging station and the electric vehicle. The alarm function monitors faults and abnormalities during the charging process and promptly alerts users or maintenance personnel to handle them, ensuring the safety and stability of the charging process. The card payment function provides a convenient payment method for charging, improving the convenience and user experience of the charging service. The wireless communication function enables wireless communication between the charging pile and the user's mobile phone or other smart devices, such as remotely monitoring the charging status and paying fees via a mobile app, improving the intelligence and convenience of the charging service.

[0029] Underground Section: The underground section consists of multiple charging modules (configurable according to requirements), transformers, circuit breakers, rectifier modules, DC contactors, fuses, three-phase meters, DC meters, and a central processing unit. This project is designed with multiple charging modules and redundant modules. Each charging module is 20kW. To optimize power supply and fully utilize the charging stack's function, each charging module is equipped with a power relay for easy switching of charging guns. The central processing unit actively monitors the battery level of the charging vehicles and automatically combines charging modules according to vehicle needs, facilitating efficient use of the charging modules. The charging modules (20kW) are the core components for realizing power conversion and supply functions. Each charging module has a certain charging power (20kW) to provide charging energy to electric vehicles. The transformer transforms the input voltage to a suitable operating voltage range for the charging system, ensuring safety and stability during the charging process. The circuit breaker disconnects the power supply in case of circuit overload or fault, protecting the charging system and electric vehicles from damage. Rectifier Module: The rectifier module converts AC power to DC power to supply the electric vehicle's battery for charging. DC Contactor: The DC contactor is used to control the connection and disconnection of the charging module to control and regulate the charging process. Fuse: A fuse is a safety protection device used to automatically cut off the power supply in case of circuit overload or short circuit to prevent fire or other safety accidents. Three-Phase Meter: The three-phase meter is used to measure the current and voltage of the input power supply and monitor the power consumption and power usage of the charging system. DC Meter: The DC meter is used to measure the current and voltage of the DC power output to the electric vehicle and monitor the energy transfer during the charging process. Central Processing Unit: The central processing unit is the intelligent control core of the charging station, responsible for monitoring, controlling and regulating the operation of the charging system. It can periodically detect the battery power of the charging vehicle and automatically combine charging modules according to the vehicle's needs to optimize and efficiently utilize charging power. Through the synergistic effect of these devices, the underground multimodal self-organizing implicit intelligent charging station can achieve efficient, safe and stable charging services for electric vehicles.

[0030] Connection Section: The connection section mainly studies the connection design between the charging modules and charging guns 4. Each charging gun 4 can be connected to multiple charging modules. Its working principle is that when an electric vehicle is charging, the central processing unit automatically detects the vehicle's battery level. When high-power charging is required, the control unit will automatically combine multiple charging modules. When low-power charging is required, the control unit will automatically reduce the number of charging modules according to the charging amount, further improving the application efficiency of the charging modules. For example, if charging gun 1 requires two charging modules, assuming modules one and two, then all blue wire switches between charging module one and charging gun one are closed. Simultaneously, all two right-side switches connected to the red wire between charging module two and charging gun two are closed, achieving the purpose of parallel connection to increase the current. The specific workflow is as follows: When an electric vehicle needs to be charged, the central processing unit will automatically detect the vehicle's battery level and determine the number of charging modules to be connected based on the charging demand. If high-power charging is required, the control unit will automatically combine multiple charging modules to meet the high-current charging demand. At this time, the corresponding switch will be closed, and a connection will be established between the charging module and the charging gun 4 to achieve parallel current connection, thereby increasing the charging power. If only low-power charging is required, the control unit will automatically reduce the number of charging modules according to the amount of charging to save energy and improve efficiency. Through the design of the connection part, the intelligence and flexibility of the charging system are realized, and the connection method of the charging modules can be dynamically adjusted according to actual needs to ensure the efficiency, safety and stability of the charging process.

[0031] In summary, the system employs multiple charging modes, such as fast charging and slow charging, to meet the needs of different users and vehicles, thus improving the flexibility and applicability of the charging stations. The charging station system features intelligent control capabilities, enabling optimized scheduling based on vehicle type, charging demand, and energy supply conditions. This allows for dynamic adjustment of charging power and intelligent energy allocation, improving system efficiency and stability. The charging stations utilize a modular design, with each module having an independent control unit and charging equipment, allowing for flexible combination and expansion as needed. This design makes the charging stations more adaptable and scalable, enabling customization and adjustment according to actual requirements. It also features efficient charging and energy-saving operation, reducing energy waste and lowering operating costs.
