30 Units of 320kW Integrated DC Chargers Powering Green Logistics in Luquan Project
01 General Overview: Luquan Heavy Truck Project
1.1 Project Background
As the logistics industry transitions toward low-carbon solutions, the Luquan District has actively promoted heavy truck electrification pilot projects. The Luquan Heavy Truck Project aims to build an ultra-fast charging network covering core logistics parks, addressing the "charging efficiency" pain point of electric heavy trucks under high-intensity operations. A total of 30 units of 320kW integrated DC chargers have been deployed, significantly shortening charging time per vehicle through ultra-high power output technology, ensuring 24/7 high-efficiency turnover for logistics fleets. As a senior energy solution provider, RW Energy provided full-stack support from equipment R&D to on-site commissioning.
1.2 Technical Specification
The integrated DC chargers used in this project strictly follow GB/T standards. The core technical parameters are as follows:
| Parameter | Specification & Requirements |
|---|---|
| Dimensions | 800 * 650 * 2000 mm (W * D * H) |
| No. of Connectors | 2 Connectors (Smart Power Distribution) |
| Rated Power | 320 kW |
| Max Output Current | Max 500 A (Liquid-cooled Cable Technology) |
| Connector Standard | GB/T (National Standard Interface) |
| Protection Grade | IP54 |
| Ambient Temperature | -30 ℃ to +50 ℃ |
| Protection Functions | Overvoltage, Lightning, Overcurrent, Leakage, Waterproof, and Emergency Stop |
02 Manufacturing Quality: High-Power Cooling and Anti-Corrosion
2.1 Core Components and Liquid Cooling (Core Components)
For the 320kW ultra-high power output and 500A continuous current, the equipment core adopts high-performance liquid-cooled charging cables. By circulating cooling media inside the cables, temperature rise from high current is effectively controlled, significantly reducing the size of the charging gun head and greatly improving the ease of plugging for truck drivers.
2.2 Modular Redundancy and Sheet Metal Process (Assembly & Process)
- Modular Redundancy Design: The cabinet integrates multiple high-power density power modules with a smart dynamic load distribution algorithm. Even if a single module fails, the charger can maintain derated operation, ensuring business continuity.
- Heavy-duty Anti-Corrosion: Considering the high-dust and high-vibration environment of logistics parks, the cabinet uses cold-rolled steel plates with a thickness of ≥2.0mm. The surface undergoes a triple process of electrophoresis, zinc-rich spraying, and weather-resistant fluorocarbon paint, reaching an anti-corrosion grade of C4 or above, ensuring no rust for ten years.
- Precision Air Duct Layout: The internal structure adopts full-path fluid air duct optimization combined with reinforced industrial-grade variable frequency fans, maintaining efficient heat exchange for core inverters even in an IP54 sealed environment.
03 Rigorous Testing: Ultra-High Power Workload Verification
Every RW Energy unit undergoes rigorous testing in standardized laboratories before delivery:
- Ultra-High Current Continuous Operation Test: 8-hour aging test at 500A peak current to monitor the heat exchange efficiency of the liquid cooling system.
- Extreme Environmental Stress Test: Simulating North China's extreme winter and summer climates, verifying low-temperature cold start at -35 ℃ and derating protection logic at +75 ℃.
- Dynamic Load Distribution Test: Verifying millisecond-level precise power distribution between two heavy trucks at different SOC states during simultaneous dual-gun charging.
- Electromagnetic Compatibility (EMC) Verification: Ensuring zero interference with wireless communications and BMS communications in logistics parks during ultra-high power operation.
04 Packing and Shipping: Precision Protection for Heavy Equipment
4.1 Packing
The equipment uses export-grade reinforced wooden pallets and is filled with high-density shock-absorbing foam. The exterior is wrapped in multiple layers of anti-static, moisture-proof plastic film and encased in wooden crates, ensuring that 30 precision units are protected from vibration, scratches, or moisture during long-distance land transport.
4.2 Shipping
All 30 units were delivered directly to the site via specialized heavy-duty logistics vehicles. During transport, the cabinet's center of gravity was mechanically fixed to prevent structural damage to internal control boards and magnetic components from vehicle vibrations.
05 Installation and Value Summary
5.1 Site Performance
At the Luquan project site, the technical team efficiently completed the positioning, anchoring, and wiring commissioning of 30 chargers. By verifying the compatibility of 400mm² large-section incoming cables with transformer capacity and strengthening the inspection of lightning protection grounding, the project achieved "plug-and-play" status.
5.2 Summary
Since commissioning, the 320kW chargers have performed excellently, meeting the "charge-and-go" requirements of electric heavy trucks. Vehicle charging turnover rate has increased by approximately 50% compared to traditional charging stations. The success of this landmark project marks a solid step for Luquan District in building a "Green Logistics Demonstration Zone" and reaffirms RW Energy's technical authority in the field of high-power fast charging.
