Electric motorbike traction drive
Bartoš, Jiří ; Vorel, Pavel (referee) ; Martiš, Jan (advisor)
This work deals with complete designing of electric drive for lightweight motorcycle. There are mentioned options of electric drive and types of batteries. One solution for Jawa 50/555 motorcycle frame is picked. In this work are measured losses of traction motor and cooling system is modified. There are some necessary calculations of drive. In next part 10S6P Li-ion battery with balancer and undercharge controller is realized. In this thesis design of step – down converter with current control is described, cooling and PCB is proposed. Complete converter with cover is made.

Power Systems Ranges of Main Parameters
Řehořek, Tomáš ; Gála, Michal (referee) ; Paar, Martin (advisor)
The thesis deals with description of the power system, parameters of it’s components and the range of outputs and consumption. In the first part the structure of the power system is described as well as the fundamental division of electric grids. In this part the work also touches on the ways of supllying the elctric traction. Furthermore the amount of production and consumption is mentioned. In the second part this work focuses on description of selected components of the power system and their real parameters. Furthermore the work also touches on the matter of electromobility and battery energy storage systems. In the last part of this work a few simple methods of consumption estimation are presented. This work also includes two infografics, that describe the power system.
