China's first pure electric sea tourism passenger ship makes its maiden voyage in Xiamen!
Recently, China's first all-electric passenger ship, the "Yujian 77," officially launched in Xiamen Bay. This vessel not only offers tourists a zero-emission, low-noise, and high-quality marine tourism experience, but also demonstrates the feasibility of applying pure electric technology in offshore waters. This breakthrough marks the acceleration of the green transformation of the maritime tourism industry.The ship's battery system, equipped with the Yujian 77, innovatively utilizes CTP technology and an integrated CCS (high-voltage charging system) to achieve a battery pack energy density exceeding 140Wh/kg. This system provides the vessel with 3,918kWh of power, enabling a pure electric range of up to 100km, sufficient to support four consecutive Xiamen Bay night cruises."Yujian77"Furthermore, after its commissioning, the "Yujian 77" is expected to reduce fuel consumption by nearly 250 tons and CO2 emissions by over 400 tons annually, equivalent to the carbon sequestration capacity of planting over 20,000 trees.The application of pure electric propulsion technology in ships provides a new technological paradigm for the green development of maritime tourism and passenger transport.As an expert in marine batteries, Bosa offers not only 24V and 48V lithium-ion battery systems for small yachts, but also lithium-ion battery systems for large cruise ships, including design complete solutions for you. Welcome to contact us to discuss more possibilities.We are always on the road to promote green energy and reduce carbon emissions!
