[0003] One of the most prominent problems is the complexity of the network architecture. Since the European standard has strict and specific requirements for the communication protocol, data interaction format and network security of the charging pile, the charging pile network architecture originally adapted to the domestic market is incompatible with the European market, requiring substantial adjustment and optimization. This process not only consumes time and effort, but also increases the entry barriers and operating costs of enterprises.

[0004] In addition, high operating costs are also a key factor restricting the promotion of existing charging pile systems in the European market. Due to the incompatibility of the network architecture, enterprises often need to invest a lot of resources in daily maintenance, fault diagnosis and software upgrades of the system, which undoubtedly increases the financial burden of enterprises and reduces market competitiveness.

[0005] Furthermore, the lack of communication flexibility is also a major problem faced by current charging pile systems. Traditional systems mostly use a single communication method, such as CAN bus or Ethernet, which makes it difficult to meet the diversified needs of remote monitoring, real-time data analysis and efficient operation in the European market. With the continuous development of advanced technologies such as the Internet of Things, big data and cloud computing, the market's demand for intelligent and networked charging pile systems is becoming increasingly high, and the existing systems are obviously not up to the task.

[0035] Network communication module includes CAN bus communication link, 4G network link, WIFI / LAN direct link link;Wherein, CAN bus communication link is used to realize the communication of DC charging host 3 and several charging terminals 4, DC charging host 3 integrates 4G network link, is connected first 4G router 5, OCPP platform 7 and customer charging APP 10 in turn through one single 4G network link;Through another single 4G network link, second 4G router 6 and equipment management platform 8 are connected in turn, and WIFI / LAN direct link link is used to realize the communication between DC charging host 3 and operation and maintenance notebook 9.

[0036] The design of the device management platform 8 fully considers the demand for efficient operation and intelligent management in the European market. Through this platform, operation personnel can access real-time data of charging piles at any time and anywhere, including but not limited to charging power, current voltage, device temperature, fault alarm and other key information. This comprehensive real-time monitoring capability greatly improves the operation efficiency, enabling the operation unit to discover and respond to any abnormal conditions of the charging pile in the first time, effectively preventing potential safety hazards and ensuring the continuity and stability of charging services. In addition, the device management platform also integrates intelligent early warning and fault diagnosis functions.
