From March 26 to 27, the 28th Expressway Informatization Conference and Technology Product Expo was held at the Fuzhou Strait International Convention and Exhibition Center. Under the theme “New Stage, New Technologies, New Landscape — Digital Transformation, Collaborative Integration, Safety and Intelligence”, nearly 300 leading enterprises and over 20,000 professionals gathered to explore smart expressway development and energy management innovation.

GWDR showcased its highway microgrid systems, AI-integrated smart energy management systems, and a full suite of new energy charging piles and energy storage solutions. Centered on “Safety, Intelligence, Reliability, and Green”, the company demonstrated its technological achievements and implementation capabilities in transportation energy digital transformation.

Exhibition Booth: Immersive Display of the Technology Ecosystem

The GWDR booth, themed “AI Empowers Transportation-Energy Integration, Dianrui Drives Green Transportation Transformation”, combined technological blue and ecological green tones. Through panoramic displays, immersive experiences, and modular layouts, it created a three-dimensional showcase. The main visual wall, featuring intelligent robots and large energy data screens, clearly conveyed the company’s positioning in technology-driven transportation energy upgrades.

The interior was divided into five zones: Core Solutions, Physical Products, Sand Table Demonstration, Case Studies, and Business Negotiation. Through panels, physical equipment, cloud platform demos, and sand table simulations, it fully presented the complete technical capabilities of expressway energy management, drawing many visitors for in-depth exchanges.

Sand Table Demonstration: Vividly Reproducing Full-Scenario Microgrid Operation

A new highlight was the physical microgrid sand table demonstration zone. Modeled after a real service area, it accurately replicated key facilities including grid connection, wind power, photovoltaics, energy storage, charging stations, and buildings. Dynamic lighting and data screens vividly demonstrated the operation logic: priority clean energy supply, peak shaving with storage, and emergency backup during grid outages, making abstract technologies tangible and becoming a booth highlight.

Integrated Energy System for Intelligent and Efficient O&M 

Expressway scenarios commonly face challenges such as insufficient power supply, pronounced tidal effects, high electricity costs, and energy transition difficulties. GWDR highlighted its microgrid systems and AI smart energy management systems to achieve cost reduction, efficiency gains, and safety improvements.

The core Microgrid Coordination Control Cabinet acts as the system “brain”, integrating grid-connection protection, synchronized measurement & control, and power quality management. Based on the “Observable, Measurable, Adjustable, Controllable” framework, it supports priority renewable consumption, peak-valley arbitrage, and virtual capacity expansion, effectively solving long-distance power supply and dispersed load challenges.

GWDR’s AI-Integrated Smart Energy Management System adopts a “localized deployment + cloud collaboration” architecture, balancing real-time performance and security. It connects to over 100 types of industrial equipment with 99.9% data integrity. Powered by AI algorithms, it enables real-time monitoring, energy consumption warnings, natural language interaction, and intelligent scheduling, significantly reducing labor costs and improving energy management efficiency.

Full Product Portfolio Covering All Expressway Energy Scenarios

At the exhibition, GWDR showcased new energy charging and energy storage products tailored for expressways, covering the full power range from small fast chargers to megawatt-level ultra-fast charging to meet all energy replenishment scenarios.

Displayed products included 80kW–240kW integrated DC charging piles, liquid-cooled ultra-fast terminals, and megawatt-level split chargers. Liquid-cooled ultra-fast chargers suit passenger vehicles and heavy trucks; megawatt split chargers meet tidal charging demands in large service area stations during holidays. Projects such as Guocun Service Area on Qiyang Expressway and Jiande Service Area on Hangzhou-Changsha Expressway demonstrate strong engineering capabilities.

Additionally, GWDR presented integrated charging-storage machines and energy storage systems. The charging-storage units combine both functions for service areas, toll stations, and emergency use. The energy storage systems support up to 12 units in parallel, enabling photovoltaic consumption, peak-valley arbitrage, and dynamic capacity expansion for low-carbon, efficient operation of expressway stations.

In-Depth Exchanges: Exploring New Collaboration Opportunities

During the exhibition, the GWDR booth attracted strong attention. Expressway operators, design institutes, and integrators from across the country visited. The technical team discussed microgrid implementation, AI energy platforms, and charging pile O&M, offering customized solutions based on benchmark projects and earning high recognition from clients.

As a national high-tech enterprise with over 20 years of expertise in transportation energy, GWDR upholds the mission “Making Energy Smarter, Transportation Safer, and the Future Greener”. The company focuses on power supply & distribution and integrated energy solutions for transportation infrastructure. This exhibition comprehensively demonstrated its technical strength and product portfolio, marking a key step in advancing smart expressway energy management.

Moving forward, GWDR will continue to deepen AI-energy integration, iteratively upgrading its core solutions in microgrids, smart energy management, and new energy charging. The company aims to drive intelligent, green, and efficient transformation of expressway energy management and contribute strong technological power to building a strong transportation nation.
