3 MW high-power split-type DC charger

Product Overview

The 3MW charging pile product adopts Advanced thermal management concepts and Cutting-edge electronic circuit technology and also Fully automated unmanned charging technology It mainly consists of a 6 kV high-voltage switchgear, a dry-type transformer for 12-pulse rectification, a high-voltage rectifier cabinet, and a robot equipped with 3D vision. The transformer’s primary side is supplied with AC 6 kV/50 Hz, while its secondary side provides two sets of AC 1180 V/50 Hz power outputs and one AC 380 V/50 Hz backup power output. The high-voltage rectifier delivers a DC output of 1500 V at 2000 A, which is fed through a dedicated charging interface to the vehicle’s high-voltage busbar, enabling the on-board charging cabinet to charge the traction battery.

      This product features a modular design, multiple protection functions, user-friendly graphical prompts, and automatic charging control; the product provides… It features CAN, Ethernet, and GPRS communication interfaces, enabling real-time communication with the monitoring center or operations management center. In the event of an anomaly, charging is immediately halted to ensure the safety of personnel and vehicles during the charging process. The monitoring center can also issue commands to limit the output power of the on-board charger and other measures, while continuously monitoring the plug‑in connection status and charging conditions in real time.

High-power output, ultra-fast charging

What does an ultra-high power of 3 MW signify?

For all‑electric heavy trucks, mining trucks, and other construction vehicles, this represents a revolution in charging speed. In the past, lengthy charging times often bottlenecked operational efficiency; however, Guangzhou Ruisu’s 3 MW high‑power split‑type DC charger can deliver energy far more rapidly than conventional chargers. In busy mining‑transport settings, mining trucks no longer need to wait extended periods for charging—brief transport intervals suffice to quickly replenish their power, significantly boosting vehicle availability and overall transport efficiency, thereby generating greater value for businesses. Value.

Split design, flexibly adaptable  

This charger features a modular design, a clever solution that delivers exceptional flexibility in application. It can be configured and installed to suit a wide range of site conditions and user requirements. Whether in space‑constrained port terminals or expansive open‑pit mines, it adapts with ease. The modular architecture also simplifies maintenance and servicing: when a specific component requires upkeep or repair, it can be addressed independently without disrupting the operation of other parts, thereby minimizing downtime and reducing maintenance costs.

Outstanding technology, stable and reliable

Guangzhou Ruishu has amassed extensive experience in the research, development, and manufacturing of charging equipment. The 3 MW high‑power split‑type DC charger is equipped with advanced liquid‑cooling technology, which effectively reduces operating temperatures and ensures stable, reliable performance even under prolonged, heavy‑load conditions. In addition, the charger features intelligent monitoring and protection functions that continuously track key parameters during the charging process; if any anomalies are detected, it promptly activates protective measures to prevent damage to both the equipment and the vehicle, delivering a safe, worry‑free charging experience for users.
