Product Overview

Electric ship drive and battery system - triple-electric system 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

250–6500 kW

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.

1714 kWh

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.

High / Low Voltage

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

SGD50 Series

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

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.

CCS / BV / DNV

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.

Core Advantages

Multi-Energy IntegrationFour operating modes: pure electric (battery or supercapacitor), hybrid (battery + diesel generator), shore charging, and emergency. Multi-energy DC bus for efficient transmission and distribution.
Smart Energy ManagementDynamic and efficient energy management: load forecasting, priority management, optimal energy scheme management, and regenerative braking energy recovery for full-route energy optimisation.
Redundant ReliabilityHigh-reliability device selection, modular design, backup power supply, and intelligent switching to ensure uninterrupted operation of critical systems (navigation, communications).
High CompatibilityCompatible with different DC voltage level power sources and loads, unit structural size compatibility, and system scheme compatibility design for both newbuilds and vessel retrofits.
BMS Three-Layer ArchitectureHierarchical management, real-time interaction, and secure control purpose-built for marine power battery systems. High-precision status monitoring (cell voltage ±5mV / temperature ±0.5°C / current ±0.5%FS), accurate life management (SOC error ≤±5% / SOH error ≤±5%).
Comprehensive SafetyThree-level fault diagnosis and protection (warning → power reduction → emergency shutdown), early thermal runaway warning (15-30 min advance, ≤0.1% false alarm rate), basic electrical protection (over/under-voltage, over-current, short-circuit, insulation monitoring), IP67 industrial protection.
