Requirements (Subjects that are assumed to be known)
For a correct understanding of this subject it is of utmost importace to have passed the 2nd year subject "Fundamentals of Electrical Engineering". Also, it is highly recommended to be skilled enough with numerical software applications such as Matlab/Simulink programming environment.
Objectives
After taking this course, the student should be enabled to describe the behaviour, analyze, design and size a variety of hybrid electric energy systems for stationary and vehicular applications. The description of these simple systems, which will include different technologies for energy storage and conversion, will be based on their electrical parameters (voltages, currents, power), but also on the energy efficiency or their economic costs. The student should be able to solve a practical, low complexity, real problem including all of the above mentioned issues.

Learning activities and methodology
The course will include: - Lecture sessions, where the theoretical aspects of the subject will be presented and debate sessinos where the students will make on oral presentation of their assigned homework, followed by a debate. - Practical sessions where practical cases and numerical problems will be presented, solved and discussed, and - Laboratory sessions, where the students will have the opportunity of a hands.on experience with this energy systems, make measurements and experience their behaviour. The students should develop a short assignment over a particular topic of this subject, that will require the search of additional information by themselves. the students are assumed to consult periodically web page in AulaGlobal2, carefully read the informations posted on it, accurately follow the instructions and deliver the assignments on time.
