Description

Lithium-ion batteries have a wide range of applications. The improvement in their energy and power densities have greatly enhanced the growth of e-mobility. Higher penetration of electric vehicles can happen faster with safer, more reliable and intelligent ali-ion energy storage systems.

This two-day course develops the concept of ‘Smart Batteries (SB)’ for Li-ion cells. Smart battery integrates power electronics and intelligent control to the cells. This is done by using a half-bridge circuit connected across the cell terminals. The course introduces the operation of the SB with the integrated half bridge circuit. 

The course gives a detailed overview of the state-of-the-art battery management systems, chargers/ charging methods. This discussion evolves into the advantages of the SB in making smart BMS and energy efficient charging methods and lifetime improvement. The design of the SB, optimal device selection, PCB design for different geometries of the cells (prismatic, pouch and cylindrical ) will be discussed. The SB also has intelligent control and the course introduces the communication architecture and controller selection for the SB management systems. 
Simulation exercises in Simulink/Plecs/LTSpice will be used as tools to understand and appreciate the SB concept and hardware architecture.

Prerequisites

Fundamental understanding of characteristics of Li-ion batteries, and familiar with programming using Simulink and any circuit simulator such as Plecs or Spice.  
Note: the course language is English. 

Form of evaluation

Students are expected to simulate SB and it’s integration with power electronics converters and make a report of the same.  

Price

8000 DKK for the Industry and 6000 DKK for PhD students outside of Denmark (VAT-FREE Education)

The Danish universities have entered into an agreement that allows PhD students at a Danish university (except Copenhagen Business School) the opportunity to free of charge take a subject-specific course at another Danish university.
