Course objectives:
|
The aim of the course is to provide students with knowledge of electromobility, i.e. electric and hybrid road vehicles. The main part of the course consists of traction drives (electric motors and power converters) powered from the battery and their specifics in the field of road vehicles, as well as traction batteries, recharging, range and power consumption of electric vehicles, mathematical modeling. Attention is also paid to prospective solutions such as multi-phase systems or wireless charging. In addition to the traction drive itself, attention is paid to other aspects of electromobility, an integral part of which is the comparison with traditional combustion engine cars.
