Development of Operational Strategies for Optimal Usage of Batteries Onboard Commercial Vessels

This paper explores strategies to optimize and extend the lifespan of onboard battery systems in commercial vessels. As sustainability becomes a priority in the maritime industry, battery technology for auxiliary power and peak shaving is gaining traction. This study discusses the challenges and opportunities of integrating this technology, including energy storage limitations, battery health, charging infrastructure, and costs. It highlights cleaner operations, reduced emissions, fuel efficiency, and improved vessel maneuverability as potential benefits. The importance of operational strategies for battery optimization is emphasized, considering factors like charging cycles, depth of discharge, operating temperature, safety, reliability, and adaptability. The paper presents a framework for developing these strategies, identifying key factors such as Full Equivalent Cycles (FEC), State-of-Charge (SoC), State-of-Health (SoH), and temperature effects. Commercial vessels are classified based on power groups with specific battery needs for each group. This work asserts that operational strategies are crucial for maximizing onboard battery system benefits. It advocates for systematic implementation to achieve sustainability targets and economic and operational advantages in the maritime industry.
