Product Overview
Leveraging core expertise in electric drive, battery and power supply technologies, the Electric Ship Drive & Battery System delivers safe, efficient and reliable electric propulsion solutions for global electric vessels, driving green and low-carbon transformation in waterborne shipping. The system covers three core segments: Electric Drive System (main propulsion inverter, power distribution), Battery System (battery pack, battery management system BMS, energy management system EMS), and Power System (shore power, charging equipment). It supports four operating modes — pure electric, hybrid power supply, shore charging, and emergency — meeting diverse power needs from inland river small craft to ocean-going mega vessels.
Three Core Systems
Electric Drive System
SGD50 series low-voltage engineering inverter covering full topology: active front-end AC/DC, DC/AC inverter, AFE rectification, and DC/DC chopper. Air-cooled and liquid-cooled platforms, 400V/690V voltage levels, modular unit and standardized cabinet design, for main propulsion, bow thruster, shaft generator and new energy vessel applications.
Battery System
Marine battery system integrating PACK, BMS and EMS, adaptable to all vessel types from inland waterway to ocean-going hybrid vessels. BMS independently certified by CCS, dual-redundant design, thermal runaway warning ≥15 min, IP67 industrial-grade protection.
Power System
Shore power solutions in high-voltage and low-voltage ship connection options, enabling shore-based charging while berthed to reduce port emissions. Charging equipment supports dual-mode fast battery swap and continuous charging for port high-frequency operation vessels.
Key Products
Low-Voltage Engineering Inverter
Air-cooled platform (IP00/IP21) and liquid-cooled platform (IP00/IP54), covering basic rectification, PWM rectification, inverter, braking chopper and filter module types. Cabinet 400/600/800mm × 650mm × 2185~2250mm, RAL7035 standard colour.
Containerized Power Supply
Standardized container structure for enhanced universality and compatibility, supporting rapid hoisting and transport to reduce logistics and deployment difficulty. Serves short-range high-frequency battery swap and long-range endurance needs across port operations and inland waterway scenarios.
Classification Society Certification
SGD50 series module units completed classification society certification; complete cabinet inverters require project-specific classification certification (drawing review, type testing). Multiple PACK, BMS, battery system and containerized power supply lines hold CCS certification, with BV, DNV, ABS, LR and RINA certifications actively progressing.
