CANCELLED! Lithium-Ion Batteries. Fundamentals, Modelling, and State Estimation (2020)

CANCELLED!
Welcome to Lithium-Ion Batteries. Fundamentals, Modelling, and State Estimation


Description:

Lithium-ion batteries have become the key energy storage technologies for various applications, such as electric vehicles, microgrids, (nano-)satellites, or for enhancing renewables’ grid integration. This has become possible due to their superior characteristics in terms of gravimetric and volumetric energy density, efficiency, lifetime etc. Nevertheless, Lithium-ion batteries are highly non-linear energy storage devices with their performance (electrical) and degradation (lifetime) behavior strongly influenced by the operating conditions (e.g., temperature, load current, number of cycles, idling time etc.). Therefore, in order to benefit from Lithium-ion batteries’ characteristics, precise knowledge about the performance and degradation behavior has to be known at all moments during the lifetime.
Thus, this three-day course provides an overview of the status of Lithium-ion batteries, fundamentals and a deep understanding of their performance and degradation behavior. Different methods for battery performance (electrical) and degradation (lifetime) modeling will be introduced together with suitable parametrization approaches (from data-sheet to laboratory experiments), respectively. These models will be subsequently used to introduce various Li-ion battery state-of-charge (SOC) and state-of health (SOH) estimation techniques.
Exemplifications of some of the discussed topics will be made through exercises in Matlab/Simulink.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
