Mobile DC Fast Charger (7kW - 60kW): The Ultimate Flexible & Roadside EV Power Solution

As the global adoption of electric vehicles (EVs) accelerates, the limitations of fixed charging infrastructure have become increasingly apparent. Traditional stationary charging posts require permanent land installation, lengthy civil works, and grid trenching. For roadside emergency assistance, automotive repair workshops, EV dealerships, and fleet operators, a flexible, mobile power source is non-negotiable.

Enter the MC Series Mobile DC Fast Charger—a cutting-edge, wheel-mounted portable DC charging solution designed to deliver fast, on-demand charging anytime, anywhere. Ranging from 7kW to 60kW with an output voltage reach of up to 1000V DC, the MC Series bridges the gap between portability and ultra-fast charging performance.

1. Universal Multi-Connector Compatibility: CCS1, CCS2, NACS, GBT & CHAdeMO

One of the biggest pain points in fleet servicing and EV recovery is connector mismatch across different vehicle brands and markets. The MC Series addresses this seamlessly by offering universal connector support:

• CCS Combo 1 & CCS Combo 2 (CCS1 / CCS2) for North American and European standard EVs.

• NACS (Tesla standard) for North American market compliance.

• GB/T for Chinese domestic and export electric vehicles.

• CHAdeMO for Japanese and global legacy EV platforms.

Additionally, the charger features built-in 12V / 24V auxiliary power supply protocols (12V/24V for GB/T, 12V for CCS1/CCS2/CHAdeMO), ensuring instant communication handshakes with discharged EV battery management systems (BMS).

2. Innovative Air Duct Design: Superior Heat Dissipation & Low Maintenance

Thermal management is critical for high-power DC equipment. The MC Series features a proprietary isolated hot and cold airflow duct design:

• Optimized Heat Transfer: Keeps thermal-sensitive power components isolated from external dust while maximizing heat dissipation efficiency.

• Enhanced Operational Stability: Prevents thermal throttling during continuous high-power output (up to 200A max current).

• Simplified Maintenance: The modular cooling pathway reduces dust accumulation inside sensitive control units, lowering total cost of ownership (TCO).

3. High Efficiency & Enterprise-Grade Safety Features

Operating with a high conversion efficiency of 95% and a power factor $\ge$ 0.99, the MC Series minimizes energy waste during power transfer.

Safety is engineered into every layer of the device:

• Enclosure Protection: IP43 rating with moisture-proof, mold-proof, dust-proof, and flame-retardant housing.

• Mechanical Strength: IK08+ crashworthiness rating (excluding screen) for rugged outdoor usage.

• Comprehensive Electrical Protections:

  • Input over-voltage & under-voltage protection

  • Output overvoltage & over-current protection

  • Short-circuit & leakage protection

  • Battery reverse connection protection & insulation monitoring

  • Lightning protection & over-temperature auto-derating (-25°C to +50°C operating range)

4. Smart Touch Controls & OCPP 1.6 / 2.0 Integration

The charger is equipped with a user-friendly 4.3-inch touch screen providing real-time telemetry (Voltage, Current, Charging Time, Fault Logs).

• Multiple Activation Methods: Supports Plug & Play, RFID Swiping Card, or Password input for secure access control.

• Smart Fleet Management: Features OCPP 1.6 / 2.0 (JSON) protocol support, enabling charge point operators (CPOs) and fleet managers to track energy consumption, schedule remote charging, and integrate with billing backends.
