DETAILED DESCRIPTION
[0034] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0035] In the present invention, unless otherwise clearly defined and limited, if the terms "connection", "fixation", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] With the widespread popularity of electric vehicles and the continuous improvement of charging infrastructure, the DC charging system, as one of the main ways to charge electric vehicles, has attracted widespread attention in the industry for its safety and efficiency. At present, the European standard DC charging system usually uses the SECC (Supplier Equipment Communication Controller) module to implement the charging communication protocol (i.e. ISO 15118 communication protocol) between the charging pile and the electric vehicle. The SECC module acts as a communication controller at the charging pile end, responsible for communicating with the electric vehicle and transmitting key information during the charging process. This one-to-one correspondence (i.e. one SECC module corresponds to one charging gun) ensures the reliability and efficiency of communication.
[0037] For example, Figure 1 As shown, Figure 1 This is a schematic diagram of a charging system architecture that uses SECC modules to implement the ISO 15118 communication protocol. Figure 1 In the charging system, the Power Management Unit (PMU) module is responsible for controlling and managing the power cabinet, realizing power distribution, over-voltage and under-voltage protection, over-current protection and other safety protection functions to ensure electrical safety during the charging process. At the same time, the Load Management Server (LMS) module is responsible for tasks such as intranet communication, interaction with the cloud platform, firmware upgrades, fault diagnosis, etc., to achieve the management and monitoring of the charging station. The Charge Control Unit (CCU) module plays a core role in the charging system. It controls and manages the charging terminal, performs insulation detection, meter power acquisition, charging management, over-temperature protection and other tasks. In addition, the CCU module also communicates with the electric vehicle through the SECC module to obtain the charging needs and other relevant information of the electric vehicle.
[0038] Depend on Figure 1It can be seen that each SECC module usually corresponds to a charging gun. Although this design can achieve accurate communication between the charging pile and the electric vehicle, the high price of the SECC module leads to a significant increase in the cost of the entire charging system. With the continuous expansion of charging infrastructure and the rapid growth in the number of electric vehicles, the high cost has become one of the important factors restricting the widespread deployment and application of DC charging systems.
[0039] Therefore, how to reduce the cost of the DC charging system while maintaining its safety and efficiency has become an urgent problem to be solved. In view of the problems existing in the prior art, the utility model proposes a European standard charging system, which achieves significant cost reduction by optimizing the module design.
[0040] In an exemplary embodiment, Figure 2 As shown, a European standard charging system is provided, including: a charging pile 10, a charging terminal 20, an electric vehicle 30, a communication module 40, a charging management unit 50 and a charging terminal detection unit 60. Among them: at least one charging pile 10 is connected to the charging terminal 20 through a charging interface, and the electric vehicle 30 is connected to the charging pile 10 through the charging terminal 20. When the electric vehicle 30 is connected to the charging pile 10, the charging pile 10 and the electric vehicle 30 are connected to each other through the communication module 40, and the charging management unit 50 is connected to the electric vehicle 30 through the communication module 40, and is connected to the charging terminal detection unit 60 through Ethernet.
[0041] The European standard charging system provided by the embodiment of the utility model realizes the connection between the charging pile and the electric vehicle through the communication module. The charging management unit, as the core of the system, is connected to the electric vehicle through the communication module and is connected to the charging terminal detection unit through Ethernet. Due to the integrated design of the charging terminal detection unit and the charging management unit, there is no need to configure a processor for each electric vehicle separately, but the electric vehicle and the charging management unit are connected through the communication module, thereby reducing the hardware cost. In addition, since the charging pile and the electric vehicle are connected through the communication module, and the communication module can be integrated with the charging pile, that is, without the need for an additional interface, the electric vehicle can be directly connected to the communication module when it is connected to the charging pile, thereby improving the operational flexibility.
[0042] In an exemplary embodiment, Figure 3 As shown, the number of charging terminals 20 , the number of communication modules 40 , and the number of charging terminal detection units 60 are equal to the number of charging piles 10 .

[0050] In this embodiment, the charging management unit is simultaneously connected to multiple electric vehicles connected to the charging pile through the communication module. Due to the integrated design of the charging management unit, there is no need to configure a separate processor for each electric vehicle.

[0053] In this embodiment, since the communication module is connected to the charging management unit through a synchronous serial data transmission protocol, the charging management unit is simultaneously connected to multiple electric vehicles connected to the charging pile through the communication module, so there is no need to configure a processor for each electric vehicle separately, reducing hardware costs.
