High-Power Li-Ion Battery Charger for Electromobil powered by Hydrogen Fuell-Cells
Šuňal, Martin ; Červinka, Dalibor (referee) ; Hejkrlík, Jan (advisor)
Main target of this thesis is deisgn High-Power Li-Ion Battery Charger. The next step is realize and energize it. Charger is designed as switching power supply concretely with regulators and electronic protects.Convertrer is directed with integrated circuit UC3845. This intelligent charger enables to get a very high output current (30A) and it has small dimensions. Usage of DC/DC convertrer as a base of a charger has many advantages like easy output current control, small dimensions, low weight and low production costs.

Balancer for Li-ion rechargeable battery
Zimčík, Václav ; Cipín, Radoslav (referee) ; Huták, Petr (advisor)
This diploma thesis is describing design and construction of battery balancer circuit for 8S Li-Ion battery pack. In the first, theoretical, paragraph the attributes of several Li-Ion battery cells are discussed, as well as differrent BMS topologies used in practice and microcontrolles commonly used to control them. In the second, practical, paragraph the design of BMS circuit prototype is discussed. This paragraph contains dimensioning of semiconductors, and their cooling, of BMS prototype, description of program which is controlling this prototype, comparision with comercial BMS and documentation for designed prototype of balancing circuit. Third paragraph, conclusion, contains summarization of gained knowledge regarding designed balnacing circuit.
