The students will have a good understanding of lithium-ion battery technology.


Content Core content Complementary knowledge Specialist knowledge
1. Introduction to energy storage. Why storage of electricity and energy in general is an important topic for the future.  Examples of electricity storage applications: solar power + storage = enabler of a 100% solar energy system, power system reserves, novel options/enhancements for conventional distribution network assets like lines, domestic back-up power, optimization of electricity trade in the wholesale electricity market, energy carrier for clean transportation, electric vehicles.    
2. Overview of battery technology: primary and secondary batteries, basic battery characteristics, conventional secondary battery technologies (lead-acid, Ni-MH etc.), introduction to lithium-ion technology.   Future prospects of battery technology development, novel battery technologies.   
3. Lithium-ion battery technology for electrical engineers: operation principle and main components of a lithium-ion cell, positive electrode materials, negative electrode materials, other components like electrolytes and separators, safety aspects, lithium-ion battery systems, battery management systems, balancing systems.   Battery manufacturing.   
4. Overview of other energy storage types: super capacitors (double-layer capacitors), superconducting magnet energy storages (SMES), flywheels, hydrogen + fuel cells.   Heat storages.   
5. Introduction of electric vehicles: what are EVs, different types of EVs, the main benefits of EVs and their motivation, the main barriers and obstacles of EVs.   Energy and environmental aspects of the transportation system, present market development.   
6. State-of-the-art EV technologies: charging technologies for passenger cars, buses, other types of vehicles, battery technology in EVs, what kind of technological solutions are used in EVs and why.  Charging infrastructure point-of-views, where and what kind of infra should be constructed, charging business/value chain perspectives.   
7. EVs in power systems and smart grids: Charging load of EVs in distribution networks, EVs as controllable loads and electricity storages for the needs of the electrical energy system.
