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.

Images from Danish Battery Symposium 2014

The Danish Battery Symposium 2014 was very well received by participants as well as speakers. The general feedback was that the amount of academic research results versus topics of common interest seemed to be well balanced. In the end, 35 participants joined together for a delicious dinner at Meyers in Kgs. Lyngby.
