Li-ion Batery Management System
Kratochvíla, Lukáš ; Macho, Tomáš (referee) ; Kopečný, Lukáš (advisor)
This thesis is about systems for Li-ion batteries. The system consists of measuring and charging. The main part of system is 3 to 5-Series Cell Li-Ion and Li-Phosphate Battery Monitor chip BQ76920. The result of this thesis is printed circuit board (PCB) with BQ76920 and a box contain PCB and battery pack. Box is designed for robot KAMBOT. The system has been tested and measured and evaluated in this thesis.

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.

LiFePO4 battery with BMS circuits for a battery drill
Fiala, Václav ; Červinka, Dalibor (referee) ; Vorel, Pavel (advisor)
This bachelor thesis deals with problematics of lithium accumulators. There are listed properties and practical use of lithium accumulators. There is also the chapter of lithium-ion-iron-phosphate accumulators, which will be a practical part of this thesis Next part of the thesis solves a safety electrical circuit system for new lithium batteries which will be able to protect batteries against overcharging or undercharging. In the practical part of the thesis new LiFePO4 batteries for the cordless drill were designed. Also, the mentioned safety electrical circuit was designed and tested.
