Key Module of State Grid Protocol: State Grid Protocol Gateway
The charging pile State Grid protocol module is a core component specifically designed to meet the communication requirements of the State Grid. As a critical part of the State Grid protocol module, the State Grid Protocol 4G Gateway aims to achieve efficient interfacing and data transmission between charging piles and the State Grid’s backend management system. The State Grid Protocol 4G Gateway not only fulfills the needs of new charging pile projects or deep integration but is also an ideal choice for upgrading old equipment and rapid deployment.
▶ 1. Core Communication Component for New Charging Piles
The State Grid Protocol 4G Gateway is an essential part of new charging piles, installed in a DIN-rail style within the charging pile to enable standardized communication with the State Grid platform. It supports national standard protocols (e.g., GB/T 27930), enabling real-time upload of charging data, status information, and fault alarms, while also receiving control commands from the State Grid (e.g., start or stop charging). This module is suitable for new devices compliant with State Grid standards, ensuring compatibility and efficiency during the charging process.
▶ 2. Upgrading Old Equipment
For older charging piles that do not meet State Grid standards, the State Grid protocol module can be embedded through hardware retrofitting to make them compliant with communication requirements. This upgrade solution is ideal for devices that require long-term operation, enabling seamless integration with the State Grid platform through module addition.
▶ 3. Intelligent Operations and Remote Management
The State Grid Protocol 4G Gateway supports real-time data interaction and remote management functions, helping operators monitor charging pile operation status, diagnose faults, and perform system upgrades. This is particularly valuable for large-scale charging networks spread across wide areas, as it improves operational efficiency and reduces maintenance costs.
▶ 4. Vehicle-Grid Coordination and Load Management
In vehicle-grid coordination scenarios, the State Grid Protocol 4G Gateway serves as part of the vehicle-pile-grid communication system, working in conjunction with vehicles and the State Grid platform. It enables charging piles to act as distributed energy resources participating in load management, such as peak shaving, load balancing on distribution networks, and assisting in renewable energy utilization. This application scenario is commonly found in projects with high levels of intelligence and digitalization on the distribution network side.
▶ 5. Supporting Interoperability and Technological Iteration
As charging piles are integrated into “new infrastructure” initiatives, technological updates are accelerating. The State Grid Protocol 4G Gateway ensures interoperability between devices from different brands by supporting standardized communication protocols, preventing asset obsolescence due to technological iteration. Additionally, it adapts to future developments in vehicle-pile-grid integration, providing a long-term stable solution for the industry.
▶ Summary
As a key module of the State Grid protocol, the State Grid Protocol 4G Gateway finds application in various scenarios within charging pile systems, including new equipment deployment, old equipment upgrades, intelligent operations, vehicle-grid coordination, and future technology expansion. Its core function is to enable efficient interfacing with the State Grid platform through standardized communication protocols, thereby enhancing compatibility, safety, and intelligence in charging infrastructure systems.
