Thesis Objective The objective of this thesis is to develop a prototype Battery Management System BMS for a 24V lithium-ion battery system using existing hardware and software tools available within the organization. In addition, the thesis will evaluate whether the current in-house software algorithms for State of Charge SoC and State of Health SoH estimation can be applied to a 24V lithium-ion battery system. The work will help assess the suitability of existing solutions and identify improvements required for future low-voltage battery management applications. Job Description This thesis is primarily focused on practical development, testing, and verification activities. Your work will include: Developing a functional hardware setup that can operate as a Battery Management System BMS prototype. Collecting and analyzing information about existing in-house SoC and SoH estimation methods. Verifying the compatibility of current software running in the Battery Management Unit BMU and Energy Management Systems with a 24V lithium-ion battery architecture. Identifying and proposing software improvements or modifications required for 24V battery system applications. Investigating and benchmarking available SoC and SoH estimation techniques used in low-voltage battery systems across the industry. Expected Deliverables The thesis is expected to result in: A functional hardware setup demonstrating Battery Management System capabilities using currently available tools and components. An evaluation of existing SoH estimation methods, including recommendations for reducing computational complexity, processing time, and implementation effort while maintaining estimation accuracy. A compatibility assessment of current software solutions for 24V lithium-ion battery systems. Recommendations for future software development and implementation strategies. Education / Program / Qualifications We are looking for a curious, motivated, and hands-on student with a strong interest in battery technology, embedded systems, electrical architecture, and sustainable transportation. You enjoy solving technical challenges, working across disciplines, and combining theoretical knowledge with practical implementatio
