A Background
The advancement of industrial civilization has driven remarkable social progress and economic growth, but it has also led to serious side effects—environmental pollution, global warming, and the degradation of ecosystems. Among these challenges, PM2.5 has become a major concern in recent years. People now express their longing for clean air with the phrase “Self-strength does not suck, thick virtue carries fog,†reflecting a deep desire for a clear blue sky.
In response to these environmental issues, countries around the world are seeking more sustainable, efficient, and eco-friendly solutions. Among them, electric vehicles (EVs) have emerged as a key part of new energy strategies and smart grid development due to their minimal environmental impact. For EVs to function effectively, they require sufficient power supply. As a result, the widespread deployment of charging stations is a crucial step in the evolution of the new energy vehicle industry.
Current Status
As the rollout of electric vehicle charging infrastructure continues, one major challenge lies in the networking and centralized management of charging stations. The power management authorities need to collect and integrate data from each station to support the development of smart grids and enable remote monitoring. However, several obstacles often arise during implementation:
1) Charging stations are often spread out over large geographic areas, making wired communication impractical.
2) Different manufacturers use varying communication protocols, which complicates data aggregation and direct communication between the management platform and the charging equipment.
Given these challenges, establishing an effective communication bridge between charging stations and the management center is essential.
System Introduction
Taking the Shanghai International Automobile City’s electric vehicle charging network as an example, the charging stations are manufactured by XJ Electric. These devices provide a CAN bus interface and support their own communication protocol. Data needs to be wirelessly transmitted to the dispatch center, where the platform software receives it in IEC 60870-5-104 format.
To meet these requirements, smart gateways must offer the following features:
1) A CAN bus interface, along with serial and network ports for field flexibility.
2) Wireless communication capabilities, including GPRS, 3G, and Wi-Fi.
3) Open architecture to allow secondary development and integration with XJ’s proprietary protocol.
4) Protocol conversion functionality to transmit data in IEC 60870-5-104 format.
5) Real-time data collection and caching, supporting remote control, status monitoring, and system alarms.
To address all these needs, Cypress’s SymLink Industrial IoT Smart Gateway series is used as the communication bridge between the charging stations and the dispatch center. The system architecture includes:
Application of Industrial IoT Smart Gateway in Charging Station Networking
The SymLink Industrial IoT Smart Gateway is an advanced, industrial-grade device designed for IoT applications. It combines embedded hardware and software, enabling remote configuration and intelligent network management. It serves as a reliable solution for connecting and interoperating across various systems.
In this setup, developers customized the SymLink gateway to support XJ’s proprietary protocol, collected field data, and enabled protocol forwarding. The data was then uploaded via 3G wireless in IEC 60870-5-104 format.
Operators can monitor the real-time status of each charging station from the dispatch center and issue commands to manage and control the equipment remotely. Remote users can access live information through PCs, tablets, or mobile devices, ensuring full visibility into the system’s performance at any time.
Conclusion
As electric vehicles and charging infrastructure continue to grow, our smart grids and intelligent transportation networks are undergoing significant transformation. Tectron Technology has been dedicated to the Internet of Things field, and through its SymLink Industrial IoT Smart Gateway products, it provides comprehensive solutions and services tailored to customer needs.
