26 Units of 240kW Integrated DC Intelligent Charging Piles for Chongqing Jiangbei Airport Smart Transportation
1. Overview
1.1 Project Background
As a major aviation hub in inland China, Chongqing Jiangbei International Airport identifies the intelligent upgrade of ground facilities as a key part of its "Smart Airport" initiative. This project, located in the underground parking lot, faces challenges such as high vehicle mobility, rapid charging turnover, and strict requirements for heat dissipation and humidity control. The client aimed to provide efficient, stable, and highly compatible energy services for passengers and airport operational vehicles through high-power DC fast charging equipment.

1.3 Solution Highlights
- Full Model Compatibility: Supports GBT (Domestic) and CCS2 (International) standards. Optimised physical interfaces and communication protocols ensure perfect compatibility with Tesla, NIO, BMW, and other global brands.
- Dynamic Power Allocation: 240 kW single unit supports dynamic intelligent balancing between dual connectors, automatically adjusting output based on vehicle BMS demand to improve efficiency.
- Smart O&M Integration: Fully supports GBT/OCPP protocols, seamlessly interfacing with airport SCADA and cloud platforms for remote monitoring and diagnostics.
2. Manufacturing & Craftsmanship
The equipment adopts an industrial-grade structural design, featuring a narrow 800mm body optimized for the limited space of underground parking lots. The internal cooling duct is independently designed to effectively handle potential dust accumulation. The internal circuit boards and core components undergo "triple-proof" (moisture-proof, salt-spray-proof, and mold-proof) coating processes and are equipped with an automatic anti-condensation heating design, ensuring stable operation in high-humidity environments (up to 95%).
3. Intelligent Control & Safety Testing
Each unit underwent rigorous Routine Tests before delivery:
- Functional Debugging: Verified the 240 kW dynamic allocation logic to ensure stability during dual-gun simultaneous charging.
- Communication Testing: Simulated SCADA integration to ensure alarm reporting, telemetry data, and remote control response times meet standards.
- Safety Protection Verification: Validated the reliability of overvoltage, leakage protection, and lightning protection systems for every unit.
4. Packaging & Transportation
Considering the strict requirements for vehicles and cargo packaging in the airport area, the equipment was sealed in high-strength wooden boxes, supplemented with anti-vibration foam and moisture-proof vacuum bags. The 26 units were delivered in batches to ensure precise synchronization between on-site installation and logistics arrival.
5. Installation & Summary
The units have been successfully installed in designated areas of the underground parking lot at Chongqing Jiangbei Airport. The technical team provided guidance on cable routing optimization and additional forced ventilation for the underground environment. Currently, all 26 charging piles have passed acceptance by the local power bureau and airport authorities. The operation of this station has significantly eased charging pressure and set a benchmark for smart hub construction.
6. Life Cycle Service
Relying on the smart O&M cloud platform, the equipment supports a "Condition-based Maintenance" mode. Maintenance personnel can retrieve real-time module temperature, voltage waveforms, and fault recording data via the backend. This enables remote positioning and diagnosis for over 70% of common faults. Specifically, the fault recording function provides core data support for precise post-event analysis and rapid responsibility determination, significantly reducing manual inspection costs and extending equipment life.
