Comparison of parameters of selected types of commercial lithium-ion batteries
Špina, Martin ; Libich, Jiří (referee) ; Bača, Petr (advisor)
This thesis deals with operation principles of Lithium-ion battery. It evaluates its characteristics, advantages, and disadvantages. Technological processes and materials used in manufacturing and recycling are also discussed. Practical part of the thesis evaluates initial capacity of given Li-ion cells at different loads. Batteries are then cyclically charged and discharged, and its capacity and other parameters are determined. Electrochemical impedance spectroscopy data are also taken and evaluated for batteries in new-like condition, used batteries and cycled batteries as the capacity fades.
Parkinson's disease in the context of the musculoskeletal system and rehabilitation care
Špína, Martin ; Hráský, Pavel (advisor) ; Majorová, Simona (referee)
Title: Parkinson's disease (PD) in the context of comprehensive rehabilitation Objectives: The aim of the thesis was to process knowledge about Parkinson's disease and methods of treatment. The practical part of it focused on examining the symptoms, methods of exercise and home conditions of patients with PD. The results were used to make recommendation for these patients. Methods: Within a theoretical part a survey was created and compiled for patients with PD. The survey anonymously addressed 15 respondents suffering from PD. The research took place in May 2021. The respondents' anonymisation was fully preserved. Results: People with PD mostly suffer from symptoms such as rigidity, tremor and deterioration of cognitive abilities. Over 50% of the respondents do regular exercise on a ball. A smaller number of them do Yoga. None of them had experience with Schultz's autogenous training and Jacobson's progressive muscle relaxation. Keywords: Treatment, physical activity, symptoms, Parkinson's disease, therapy, comprehensive rehabilitation.
Voltage converter with MPPT algorithm for solar cell
Špina, Martin ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
This thesis deals with design of solar lithium ion battery charger using microcontroller controlled step down DC/DC converter. Control algorithm is designed to utilize most the of the energy coming from the solar photovoltaic panel, by using maximum power point tracking technology. This makes it as efficient as possible at any irradiation intensity level or temperature.
