Battery Solutions and Aging Process Simulation for Maritime Electric Propulsion

Climate change poses a significant challenge to human life and ecosystems. Today, the maritime industry faces increasing pressure to reduce its carbon footprint, with all stakeholders required to comply with the International Maritime Organization (IMO) regulations. To support the design of innovative ships, the Siemens Simcenter portfolio provides solutions that meet IMO specifications. Electrical propulsion systems are particularly important for vessels operating in Emission Control Areas (ECAs), where carbon emissions can be significantly reduced. The main objective of this article is to simulate a fully hybrid electric ship propulsion architecture and evaluate the aging process of its battery system. Battery capacity loss over the system’s lifespan is determined using aging test data to calibrate an empirical aging law.
