Core Viewpoint - The launch of the "Yujian 77," China's first fully electric passenger ship, marks a significant step towards the green transformation of the maritime tourism industry, showcasing the feasibility of pure electric technology in coastal navigation [2][3]. Group 1: Technological Innovations - The "Yujian 77" is equipped with CATL's marine battery system, utilizing CTP (cell-to-pack) technology and integrated CCS (high-voltage charging system) technology, achieving an energy density breakthrough of 140Wh/kg [2]. - The battery system provides a total power capacity of 3918kWh, enabling a pure electric range of 100km, sufficient for four consecutive night tours in Xiamen Bay [2]. - Safety features include NP (no thermal propagation) technology, ensuring that thermal runaway does not spread, and an IP68 protection level, allowing the ship to withstand 1296 hours of salt spray testing [2]. Group 2: Environmental Impact - The operation of the "Yujian 77" is expected to reduce fuel consumption by nearly 250 tons annually and cut carbon dioxide emissions by over 400 tons, equivalent to the carbon offset of planting more than 20,000 trees [3]. - The ship has received certifications from major global classification societies, including CCS, BV, ABS, and DNV, highlighting its compliance with international safety and performance standards [3]. Group 3: Future Developments - CATL plans to continue enhancing technological innovation, focusing on developing safer, longer-lasting, and higher energy density marine battery systems to promote a zero-carbon future for water transportation [3].
