During the semester, I conducted an analysis of the battery system, focusing on transitioning from lithium sulphur to lithium-ion batteries. After evaluating the power requirements, I determined the number of cells needed for the new lithium-ion battery system. Additionally, I worked on optimizing the charging process for the system to ensure efficient and effective performance. Overall, the project involved a comprehensive examination of the battery system, from selection to implementation, with a focus on enhancing its functionality and reliability.
