Product Introduction
Designed for ultra-fast charging applications, this 720kW flexible interconnected group-controlled megawatt charging system fits urban public charging hubs, motorway service areas and national long-distance highway networks. It supplies continuous high-power rapid charging for heavy trucks, vessels and other devices requiring large power input. This system features a separated layout with one charging rectifier master cabinet paired with multiple distributed charging terminals.
The system establishes a flexible, high-performance group control framework, scalable to a maximum total capacity of 4.8 MW. Its key hardware covers high-efficiency charging modules, smart power controllers, power switching matrix, charging-control units, 4G wireless communication modules, high-accuracy energy meters and 7-inch HMI touch panels. You can pick between two charging connector standards: GB/T 20234 for local market deployment and IEC62196-3 (CCS2) for European specification projects. The whole system features IP55 ingress protection.
Product Features
- Power Pool Architecture: Centralized power pool supporting dynamic flexible power allocation; single gun output reaches ≥1MW, designed to accommodate upcoming ultra-fast charging demands.
- Ultra-Wide Voltage, Full Coverage: DC output ranges from 200–1000V, with constant power within 300–1000V. It supports passenger vehicles, heavy-duty trucks and construction machinery.
- Level-1 Efficiency, Lower Costs: Weighted system efficiency hits ≥96.5%, 1.5% better than conventional charging hardware, cutting annual operating expenses by more than 20,000 RMB per unit.
- AI Self-Diagnostics + OTA: Built-in self-inspection and self-protection capabilities, paired with remote OTA firmware updates, enabling predictive maintenance and smart system administration.
- Multi-Layer Safety Protection: Adopts 108 advanced active protection logics, deep BMS communication, flexible power scheduling and full battery status monitoring, shifting safety control from passive reaction to proactive prevention.
- Comprehensive Protection: Full-spectrum active safeguards including overvoltage, undervoltage, overload, short-circuit, leakage, over-temperature, surge protection, emergency stop and power cut when cabinet door opens, delivering real-time risk detection and immediate fault disconnection.
