"Development of a Robust Marine Traction Voltage Battery Suspension System"
Abstract:&nbsp; Volvo Penta is advancing marine electrification to meet sustainable transport goals, but traction voltage batteries face unique vibration and shock challenges in high-speed vessels. This thesis develops and evaluates suspension solutions, including some of the main dampers used in marine segments, through analytical and simulation methods. The results show how optimized designs can reduce resonance, improve reliability, and ensure compliance with marine safety standards, enabling robust battery integration in demanding marine environments.
