Langh Tech held last week the official product launch of its new battery system at the Nor-Shipping trade show in Oslo. The product was presented during a brunch event in the morning, with a speech by Managing Director Laura Langh-Lagerlöf.
The aim in the product development has been to bring to the market a reliable and affordable battery solution. The process started in 2023 to create an alternative for shore power connection when meeting the upcoming regulation of vessels not being allowed to use auxiliary engines in EU ports.
The Langh Tech battery system is designed to provide the vessel with reliable electrical power for shore-side operations and to assist in or fully provide propulsion during cast-off — ensuring seamless, efficient, and environmentally conscious manoeuvring. A battery string consists of up to twenty connected battery packs, with the number of strings flexible up to sixteen units per battery room, giving an energy storage capacity of 5 MWh.
The system includes several features to ensure a high safety level, also evident in the IP68-rated protection level. Each battery pack includes a dedicated off-gas duct, safely channelling gases out of the battery space to maintain a non-toxic and non-flammable environment. Fire protection is additionally ensured through early-stage threat detection. Cell-to-cell isolation prevents the spread of thermal runaway, significantly enhancing onboard safety and system resilience. An integrated liquid cooling features provides a stable and cozy environment for the cells, which is more accurate and efficient compared to air cooling. LFP chemistry offers superior thermal resistance and eliminates risk of thermal runaway, outperforming both traditional lithium-ion (e.g., NMC) and lead-acid batteries in safety, longevity, and environmental impact.
The system is engineered for easy installation and maintenance with minimized operational disruption. An active balancing software optimizes performance and extends battery life, with constant health check on cell and pack level. In the unlikely event of a pack failure, manual string cut-off will ensure continued operation.
Langh Tech’s sister company Langh Ship’s three 1200 TEU newbuildings have been designed with battery room, and battery system installations are in progress for these vessels.
