摘要

Inland electric-drive ships present a unique opportunity to achieve zero-carbon emissions, significantly advancing the "carbon peak and carbon neutrality" strategy. The present research critically examines the advantages and disadvantages of various energy types for newly designed ships. A comprehensive demonstration and analysis of feasibility and applicability are provided, taking into account factors such as technological maturity, cost-effectiveness and the current state of the industry chain. Furthermore, key technologies and system integration research are undertaken from three pivotal perspectives: ship design technology, electric propulsion technology, and battery safety technology. Computational Fluid Dynamics (CFD) and model tests are synergistically utilized to optimize the mold line for inland electric-drive ships, which are characterized by low speed, large capacity, and excellent EEDI. Finite Element Method (FEM) and structural optimization methods are employed to ensure structural safety, reliability, and lightweight design. The ship-motor-propeller system is analyzed to identify the optimal match among them. Subsequently, the high-efficiency electric thrust system, inclusive of protection and energy management technologies, is discussed. The discussion also covers the high safety of cells, modules, packs, and battery systems. These areas collectively contributed to the development of a series of electric-drive merchant ships, passenger ships, and yachts.
