Practical Application Scenarios
Short-Dwell Passenger Ferry Top-Ups: During 15-to-30-minute passenger boarding intervals at urban terminals, the 600A liquid-cooled dispenser delivers intense, rapid DC energy. This allows ferry operators to maintain all-day continuous service without installing oversized, heavy battery banks on board.
Overnight & High-Power Harbor Workboat Recharging: For electric tugboats, pilot vessels, and service craft returning to port after demanding marine operations, the 960kW power stack automatically manages high-voltage DC delivery to replenish high-capacity battery packs safely overnight or between shifts.
Multi-Vessel Fleet Terminal Charging: Utilizing full-matrix dynamic power allocation, a single charging installation can power multiple vessels docked simultaneously-intelligently routing higher currents to the ship requiring the fastest turnaround.
FAQ
Q: Is this charger suitable for harsh marine and saltwater dockside environments?
A: Yes. The power stack features an IP55 rating, while the dispensers are rated up to IP65 for dust and water protection. The outer enclosure undergoes specialized anti-corrosion surface treatment and salt spray resistance testing to ensure long-term durability on wet, saline coastal piers.
Q: What voltage platform does this charging system support?
A: The system operates on a wide DC output voltage range from 150V to 1000V DC (with the power stack constant power range covering 300V to 1000V DC).
Q: What safety protections are built into the system to prevent electrical faults or battery damage?
A: The unit complies with the GB/T 18487.1-2023 standard and includes eight integrated safety protections: voltage anomaly, over-current, leakage, short-circuit, temperature anomaly, BMS fault protection, surge protection (Level 4), and an emergency stop button.
Q: Can this marine charger be integrated into an off-grid or solar-plus-storage (BESS) microgrid?
A: Yes. Designed for port electrification, the system integrates seamlessly with solar photovoltaic arrays and battery energy storage systems (BESS).
Q: What human-machine interface (HMI) is provided on the dispenser for dock operators?
A: Each dispenser is equipped with a 7-inch color touchscreen display. The intuitive user interface displays real-time charging status, battery State of Charge (SOC), charging voltage/current, elapsed time, and fault diagnostics.
