background
With the increasing global pursuit of clean energy and sustainable development, new energy vehicles, as a green and environmentally friendly mode of transportation, are gaining widespread market favor. Along with the rapid increase in the number of new energy vehicles, charging demand is also experiencing explosive growth. As "energy replenishment stations" for new energy vehicles, the construction and improvement of smart charging piles are key factors in promoting the popularization of new energy vehicles. As a crucial link in the electric vehicle industry chain, smart charging piles possess network communication capabilities, enabling them to interact with new energy vehicles and intelligently schedule charging based on demand. Smart charging piles can automatically adjust charging strategies according to users' time and power needs, improving charging efficiency and reducing charging time. Therefore, the stability and intelligence level of their communication systems directly affect the user's charging experience and the operational efficiency of the charging piles.
Shanghai Zhaoyue Communication Technology Co., Ltd. has proposed a smart charging pile communication system solution to address the challenges currently faced by smart charging pile communication systems. The solution aims to solve problems related to the distribution, communication, and management of charging piles, ensuring efficient, safe, and convenient charging services.
System Overview
The intelligent charging pile communication system includes the charging pile system, access system, network application platform, operation and management center, and terminal applications based on the service platform. The entire system enables information exchange between the charging pile, vehicles, power grid, and management system through specific communication protocols and mechanisms.
System advantages
1. High efficiency
The intelligent charging pile communication system significantly improves the efficiency of charging pile utilization through advanced intelligent management and optimization technologies. The system can intelligently schedule charging tasks and automatically adjust charging strategies based on factors such as vehicle power demand and real-time charging station load, ensuring maximum utilization of charging pile resources.
2. Safety
In terms of data transmission, the most advanced, secure, and reliable communication technologies and encryption protocols are employed. This ensures a high level of security in the communication process between the charging pile, the vehicle, the power grid, and the management system, effectively preventing security risks such as data leakage and unauthorized access.
3. Convenience
To meet the needs of different users, a variety of charging and payment methods are offered. Whether it's fast charging or slow charging, users can choose the most suitable charging method according to their needs.
4. Manageability
The intelligent charging pile communication system supports remote monitoring and management, facilitating equipment maintenance and management for operators. Operators can view the charging pile's operational status in real time through the system platform and perform remote equipment maintenance and debugging. This not only improves operator efficiency but also reduces equipment maintenance costs.

Features of Smart Charging Pile Solutions
1. The overall solution adopts a modular design, which facilitates the later maintenance and expansion of each subsystem. The backbone LAN adopts a gigabit fiber optic ring network to enhance the overall stability and reliability of the system;
2. The core switch of the centralized monitoring center adopts a rack-mounted Layer 3 industrial Ethernet switch, which forms a fiber optic ring network with each subsystem. It is also connected to the office network and the monitoring screen. Data and on-site video from each subsystem are aggregated, and managers can view the on-site working status in real time from the monitoring center.
3. Each battery swapping station uses a ring network switch to form a fiber optic ring network with the monitoring center. The ring network switch is divided into 3 VLANs, allowing independent communication between the barrier gate, video system, and battery swapping devices with the centralized monitoring center and local processing unit. This optimizes the use of switch forwarding resources, ensuring no interference between VLANs, guaranteeing smooth video transmission and accurate control data.
4. The automatic battery swapping device adopts wireless communication. The industrial wireless AP provides WIFI coverage to the entire site. The battery transfer RGV and the battery swapping device all use wireless connection.
5. The centralized charging system also uses a ring network switch to connect to the monitoring center. The switch is connected to Ethernet data from the electricity meters, relay protection devices, data acquisition devices, etc. in the charging room.
6. The environmental monitoring system in the charging room uses an industrial-grade serial server to connect on-site serial bus devices such as fans, temperature and humidity sensors, heat dissipation systems, and access control systems. This enables RS-232/422/485 serial ports to be converted to TCP/IP and connected to the charging room's ring network switch. This serial service supports multiple working modes, including VX-Bus, virtual serial port, TCP, UDP, and Modbus/TCP, providing design engineers with flexible implementation options.
7. Each charging station utilizes one Shanghai Zhaoyue 5G+WIFI router MWG-3611 series. This series of routers features high speed, low latency, and multiple interfaces. It supports the IEEE 802.11ax WIFI6 communication standard and 5G/4G access. Employing a high-performance WIFI processing chip, the 802.11ax maximum speed reaches 1800 Mbps, providing users with long-distance wireless data transmission and routing functions. On-site WIFI coverage is provided for staff to use with handheld devices, and can also be used for system debugging. The 5G function uploads data to the cloud platform, allowing customers to schedule battery swapping services and monitor the progress and status of their vehicles in real time via a mobile app. Remote payment can also be completed simply by using a mobile phone.
