Product Introduction
This 640kW megawatt-grade flexible interconnected group-controlled charging system is designed for ultra-fast charging deployments. It fits urban public charging hubs, motorway service zones and long-distance national highway networks, delivering consistent megawatt-level rapid charging for heavy-duty trucks, vessels and other high-power-demand devices. The system uses a separated layout made of one charging-rectifier main cabinet plus multiple distributed charging terminals.
It builds a flexible, high-efficiency group-control framework expandable to 4.8 MW. Key hardware includes high-efficiency charging modules, smart power controllers, power switching matrix, charging-control units, 4G wireless communication modules, high-precision energy meters and 7-inch HMI touch panels. Two charging-connector standards are available: GB/T 20234 for domestic market and IEC62196-3 (CCS2) for European-spec projects. The full set of equipment achieves IP55 ingress-protection grade.
Product Features
• Ultra-Wide Voltage, Full Coverage: The 640kW Megawatt MCS charger delivers DC output ranging from 200V to 1000V with constant power across the 300–1000V band. It supports charging for passenger EVs, heavy-duty trucks and construction machinery for broad vehicle compatibility.
• Power Pool Architecture: Adopts a unified power pool design featuring dynamic and flexible power allocation. It supports single-gun output ≥1MW, fully prepared for upcoming megawatt-level ultra-fast charging requirements.
• AI Self-Diagnostics + OTA: Built-in automatic self-check and self-protection functions. Remote OTA firmware updates enable predictive operation & maintenance and intelligent whole-station management.
• Level-1 Efficiency, Lower Costs: The weighted system efficiency reaches ≥96.5%, 1.5% better than conventional charging hardware. Each system can cut annual operating expenses by more than 20,000 RMB.
• Multi-Layer Safety Protection: Equipped with 108 industry-leading active protection logics. It achieves deep BMS communication and flexible power scheduling plus continuous battery monitoring, transforming safety from passive reaction to proactive prevention.
• Comprehensive Protection: Packed with full-range active safeguards including overvoltage, undervoltage, overload, short circuit, electric leakage, overheating, surge protection, emergency stop and door-opening power cut. It detects hazards in real time and actively cuts off power once faults occur.
