Electrochemical Properties of Lithium-Ion battery under Elevated Temperature
Kulíková, Barbora ; Chladil, Ladislav (referee) ; Bača, Petr (advisor)
This Master’s thesis deals with a monitoring of the temperature influence on Li-ion batteries, literature search of this topic and proposal of experiments. First chapter contains the theory of evolution and fundamentals of the Li-ion batteries. Planned experiments with flow charts and block diagrams are described in the second chapter. The work station is explained along with a description of the execution of the experiments in the third chapter. The experiments are analyzed and results explained in the last chapter.

Smart Li-ion Batery
Prachař, Vojtěch ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deals with lithium accumulators with electronics, which are composed to a unit called Intelligent Battery. Within this thesis, the main features of these accumulators are explained and the circuit to monitor these accumulators has been designed and manufactured, it can disconnect them when the parameters are exceeded, and it stores the history of the battery measurement in memory. It also allows reading of current and logged battery data via UART. The computer application is designed for communication, to display the information and to adjust the battery circuit parameters. The electronics secure charging when the 24V adapter is connected according to the set parameters and it also secure balancing of the individual accumulators.

Microprocesor controlled charger
Husník, Ondřej ; Ježek, Michal (referee) ; Kovář, Jan (advisor)
This thesis deals with design of microprocessor controlled battery charger with support of NiCd, NiMH and Li-Ion cells. The project focus is aimed within circuits design at algorithm of charge detection implemented into microprocessor. User interface is formed by PC application which communicates with charger via USB. PC connection allows recording of charging characteristics behaviour. The result of thesis is completely designed and created battery charger including microprocessor and PC application source codes.

Electrochemical Properties Of Lithium-Ion Battery Under Elevated Temperature
Kulíková, Barbora
This article presents a topic of the elevated temperature influence on lithium-ion accumulators. The theoretical part of the paper focuses on the basic principles of lithium-ion batteries, their advantages and influence of the temperature on their functionality. The experimental part deals with three different experiments comparing measured and manufacturers’ parameters, and examining the influence of the temperature and current on a capacity along with charging and discharging characteristics.
