In modern new energy charging station construction, high-power DC charging piles in centralized power supply scenarios frequently encounter critical challenges: high load density, transformer overheating from prolonged full-load operation, and delayed equipment condition monitoring. These issues directly impact both power supply stability and equipment lifespan. To address this, Hongwei Power has developed a customized charging station power solution for scenarios featuring two 2000kVA transformers and ten 400kW DC charging piles. The solution focuses on optimizing transformer cooling design and enhancing intelligent monitoring systems, ensuring stable long-term full-load power supply. This approach guarantees efficient continuous operation of charging piles while improving operational reliability and service capabilities.

Core power supply equipment: 2 charging station dedicated power transformers, each with a rated capacity of 2000kVA, totaling 4000kVA. These transformers are compatible with 380V industrial power supply and deliver output matching the charging piles' power requirements. They support 10400kW DC charging piles operating at full load simultaneously, with reserved space for future expansion.

10 DC charging terminals, each with 400kW power and fast charging capability, compatible with mainstream new energy vehicle charging interfaces. This setup supports simultaneous ultra-fast charging for multiple vehicles, enhancing the service efficiency of charging stations.

Cooling System: Enhanced Intelligent Cooling and Ventilation System with a combination of high-power cooling fans and high-efficiency heat sinks. Equipped with an intelligent temperature control module that automatically adjusts the cooling level, it solves the problem of excessive temperature during long-term full-load operation of the transformer and maintains a constant temperature for the equipment.

The monitoring system is a remote intelligent monitoring platform that collects core data such as current, voltage, temperature, and load rate in real time. It supports remote viewing, fault alerts, and data traceability to achieve full-time control of equipment operation status and promptly identify operational risks.

1. Full-capacity power supply with stable load: Two 2000kVA dedicated transformers provide coordinated power supply, delivering a total capacity of 4000kVA. This fully meets the demand for 10400kW DC charging piles operating at full load simultaneously. The system ensures sufficient power redundancy, effectively preventing power outages and power reduction issues caused by overload, thus guaranteeing round-the-clock stable operation of the charging station.

2. Enhanced Thermal Management for Extended Lifespan: The transformer's cooling system has been specifically upgraded with high-power silent fans and high-density heat sinks, achieving 40% higher cooling efficiency than conventional designs. Integrated with smart temperature control technology, the system monitors real-time equipment temperature and automatically adjusts cooling intensity. This ensures 24/7 full-load operation with stable temperature within safe limits, effectively preventing equipment aging and downtime caused by overheating.

3. Smart Monitoring for Easy Maintenance: Featuring a comprehensive remote monitoring system, it captures real-time core data including transformer current, voltage, operating temperature, load rate, and charging station status with zero-latency transmission. The system supports remote access via PC or mobile devices, equipped with real-time fault warnings and anomaly alerts. With 98% fault localization accuracy, it enables full lifecycle equipment management without on-site monitoring, significantly reducing maintenance costs and labor requirements.

4. Robust Safety and High Adaptability: The transformer features high-conductivity copper windings and high-strength insulation materials, delivering exceptional impact and short-circuit resistance. It is specifically engineered for high-load, high-frequency power supply scenarios in charging stations. The system incorporates comprehensive protection against lightning, overvoltage, overcurrent, and leakage current, ensuring full-spectrum power supply and charging safety in compliance with new energy charging station safety standards.

When transformers operate at full load for extended periods, overheating increases failure risks. The upgraded system features enhanced power dissipation fans, high-efficiency heat sinks, and an intelligent temperature control module. This configuration efficiently dissipates operational heat, maintains stable temperature, and extends equipment lifespan by over 30%.

Multiple charging piles operating simultaneously may cause insufficient and unstable power supply. The system is equipped with dual 2000kVA dedicated transformers to fully meet total power demands while reserving expansion capacity. This ensures stable power supply, optimizes performance for high-load centralized charging scenarios, and enhances the service capability of charging stations.

The equipment's operational status is poorly managed, resulting in high maintenance difficulty. By establishing a remote intelligent monitoring platform, we can comprehensively collect core operational data, enabling remote control and fault prediction. This allows real-time monitoring of equipment status, early detection of potential issues, reduced on-site maintenance frequency, and lower operational costs.

1. Pre-sales phase: Our technical team works one-on-one with clients to optimize equipment placement and wiring plans based on actual requirements such as charging station layout, charging capacity, and power supply conditions, ensuring the solution meets on-site operational needs.

2. Mid-sales phase: We provide integrated installation and commissioning services for transformers, monitoring systems, and charging piles, conduct on-site operation training, and assist in system trial operation and acceptance to ensure swift equipment deployment.

3. Post-sales service: We provide lifetime technical support, scheduled equipment inspections, and rapid fault repair services, along with free upgrades to the monitoring platform. This ensures timely resolution of operational technical issues, guaranteeing the charging station's continuous and efficient operation.

This charging station solution centers on dual 2000kVA dedicated transformers, specifically addressing critical challenges including high-load power supply, prolonged full-load equipment heat dissipation, and intelligent operation and maintenance. Through core designs featuring adequate power supply, enhanced cooling, and smart monitoring, it ensures stable, efficient, and safe operation of charging stations. The solution not only accommodates simultaneous full-load operation of multiple high-power charging piles but also reduces equipment maintenance costs and failure risks. By providing reliable power supply support throughout the entire process, it enhances operational profitability and service quality for new energy charging stations.
