1. 21. A DMAIC based framework to conduct Measurement System Analysis : A case study at Northvolt AB

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Anshuman Manickam Vinoth; [2021]
   Keywords : ;

   Abstract : The aim of the project was to develop a framework for the execution of a Measurement System Analysis (MSA) which would help determine capability of a measurement system. The strategy behind carrying out this thesis has been to draft a framework which is based on the Define, Measure, Analyze, Improve, Control (DMAIC) model for a Measurement System Analysis (MSA) which would enable to gain a better understanding of the capability of measurement instruments that are used to control the quality of production processes of lithium-ion batteries.

   Abstract : Detta projekt syftar till att undersöka den termiska rusningsprocessen hos ett litiumjonbatteri med en fluorfri elektrolyt och jämföra den med en kommersiellt använd fluor-innehållande elektrolyt. Battericellerna innehöll silikon-grafit som anod och LiNi0.6Mn0.2Co0. READ MORE

4. 23. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mantas Petrosius; [2021]
   Keywords : ;

   Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
