Battery System Expansion to Meet Medium-to-Long-Range Demands
The newly launched SUPER/ISLAND Battery Platform has achieved system-level capacity expansion, featuring exceptional modular configuration capabilities. Each outboard motor system can be configured with up to 270 kWh, while a dual-motor system can extend to 540 kWh, and a four-motor system can achieve a total energy capacity of 1,080 kWh. This not only meets the high-frequency usage demands of working boats and leisure boats but also makes the full electrification transformation of traditional, high-fuel-consumption vessels, such as medium-sized ferries, a realistic possibility.
High Energy Density and Dual Thermal Management for Multi-Climate High-Performance Needs
On the performance front, the SUPER/ISLAND Battery Platform uses next-generation cells with an energy density of 250 Wh/kg, effectively balancing long lifespan, lightweight design, and high-power output requirements. This allows the entire system to maintain extended range while offering agile power response. The battery supports 1C to 2C high-discharge rates and fast charging capabilities and is compatible with both 400V and 800V voltage platforms, interfacing with mainstream port fast-charging networks to significantly improve energy replenishment efficiency at harbor and temporary dock sites.
Moreover, to address multi-climate operational challenges, the SUPER/ISLAND Battery Platform incorporates a dual thermal management system: a liquid cooling system ensures stable operation in hot climates, while an electronic heating system quickly activates in cold conditions to maintain cell activity and safe discharge. This dual-temperature intelligent thermal control design ensures that electric boats can operate stably in various climate conditions worldwide, enhancing the global navigability of electric systems.
Boatyard-Friendly, On-Demand Expansion, Creating a Flexible and Efficient Integrated Solution
The SUPER/ISLAND Battery Platform is designed for seamless integration into diverse vessel designs. Its modular architecture features a compact double-layer cell stack (710 mm wide, 300 mm high), making it easy to install in the stern while optimizing vessel balance.
ExploMar’s proprietary BMS and integrated high-voltage E/E architecture allow each system to support up to three battery packs, enabling on-demand expansion. This flexibility benefits both boatbuilders and service providers—simplifying installation in new builds and improving aftermarket adaptability for energy upgrades and replacements.
With the launch of the SUPER/ISLAND Battery Platform, ExploMar eliminates the 200 km range as a technological ceiling and redefines what’s possible in electric marine travel. This innovation supports the broader electrification of water transport—accelerating adoption, enabling new use cases like island transport and cross-shore commuting, and paving the way toward a low-maintenance, zero-emission, high-performance future on the water.
