Description of PhD project
The scope of the PhD project was to analyse, investigate and develop various aspects of emerging lithium air (Li-air) batteries. The outcome of this project was to develop and demonstrate a Battery Management Systems (BMS) suitable for Li-air batteries.
The three main focus areas of this PhD project were:
1. Analysis of functional safety requirements for Li-ion and Li-
air battery technologies with focus on the automotive
segment and their standards.
2. Development of novel algorithms for predicting battery life
in Li-air (and by extension Li-ion) batteries. This may include new sensor technology that will be investigated as well.
3. Development and implementation of algorithms for Li-air batteries and implementation of life- prediction algorithms in a battery management system that is developed using automotive functional safety architecture.
The PhD project was performed in close co-operation with the R&D team at Lithium Balance and the Department of Energy Conversion and Storage, DTU. The PhD project was part of the ReLiable project, which was a research collaboration aimed at developing Li-air batteries, funded by the Danish Strategic Research Council.
Biography
Andreas Elkjær Christensen is a M.Sc Engineering from the Technical University of Denmark, graduating in 2009. In 2016 he completed an industrial PhD, which was a collaboration between Lithium Balance A/S and DTU Energy at the Technical University of Denmark. During his PhD, Andreas researched new battery technology in form of Lithium-air batteries, with special focus on applications of electrochemical impedance spectroscopy for battery management. This work has resulted in two pending patents. Andreas’ work at Lithium Balance A/S is focused on project management, embedded software development, functional safety in road vehicles and supervising patent applications and grants. He is currently a board member at the Danish Battery Society.
