| 摘要:聚焦CIMAC 2025大会，分析船舶电力推进系统的发展趋势。当前船舶动力领域正经历从传统燃油向电力驱动的革命性转型，除了传统柴油机组电力推进，其余电力推进系统按能量来源可分纯电力推进和混合电力推进系统。如今，纯电力推进在渡船等短距离场景中已实现商业成熟，但在远洋船舶应用中受限于能量密度和快速充电瓶颈。相较于国外，国内在纯电力推进领域发展迅猛。混合电力推进系统兼具传统动力的续航能力与电力推进的效率和减排优势，具有广泛的适用性和灵活性，主导着船舶电气化市场。船舶各个系统逐步实现自动化控制和智能化管理，提高船舶运行的可靠性和安全性，进一步推动船舶电力推进系统智能化进程。 |

| Abstract:The development trend of marine electric propulsion systems is analyzed based on CIMAC 2025 Congress.The current field of marine propulsion is undergoing a revolutionary transformation from traditional fuel to electric propulsion. In addition to traditional diesel powered electric propulsion，other electric propulsion systems can be divided into pure electric propulsion and hybrid electric propulsion systems based on energy sources.Nowadays，pure electric propulsion has achieved commercial maturity in short distance scenarios such as ferries，but its application in ocean-going vessels is limited by energy density and fast charging bottlenecks.Compared to foreign countries，China has developed rapidly in the field of pure electric propulsion.The hybrid electric propulsion system combines the endurance of traditional power with the efficiency and emission reduction advantages of electric propulsion，and has wide applicability and flexibility，thus is leading the ship electrification market.Various systems of ships are gradually achieving automated control and intelligent management，improving the reliability and safety of ship operations，and further promoting the intelligent process of ship electric propulsion systems. |
