Objective

Course deals with charging systems of electrical vehicles (EV). After completing the course, student:
- Recall features of EVs concerning electricity consumption and battery types, including charging power and battery capacity
- Can interpret regulations and standards concerning EV charging, and can apply them when designing EV charging systems
- Can explain the structure and features of EV charging devices, and choose charging devices for different applications
- Recall the principles related to charging system control and management
- Can design charging system for single EV as well as parking areas

Laboratory exercise for the practical part

Exam schedules

ISTLearning Exam on-line in the class room about theory (1H test)
1 retake possible either 26.11.2024 or 10.12.2024

Pedagogic approaches and sustainable development

The educational process aims at understanding eV chargers functionality, and controllability, including type of equipment or control strategy on the size and performance of the systems.
Calculation exercises and simulation projects help the students to think for themselves and understand better.
The class is multi-cultural, with a relevant proportion of exchange students, which make lectures like an exchange.
