	Influence of titanium dioxide on the life of lead acid batteries with applied pressure Řihák, Pavel ; Křivík, Petr (referee) ; Bača, Petr (advisor) Hybrid electric vehicles use lead acid batteries operating under partial charge. Battery life of these batteries is dependent on the speed of development of lead sulphate (PbSO4) to the negative electrodes. Different admixtures are affected battery life. This work deals with the influence of titanium dioxide on the negative active material in lead battery. Mainly devoted to the influence of the applied pressure. Detailed record
	Influence of different types of AGM separators on parameters of lead-acid batteries for hybrid electric vehicles Čada, Miroslav ; Vaculík, Sebastian (referee) ; Tošer, Pavel (advisor) The most used type of the secondary energy sources is the lead-acid accumulator today. It is also used as a propulsion in hybrid electric vehicles. Functional principle stayed same as in foundation time, only parameters are still improving. Lifetime of lead-acid accumulator is influenced by used separator. The work deals with the description of properties of lead acid separators, methods of testing and evaluation of the suitability for use. Detailed record
	Effect of additives in lead-acid batteries for hybrid electric vehicles. Klaner, Pavel ; Vaněk, Jiří (referee) ; Bača, Petr (advisor) This thesis deals with issues of the issue lead-acid batteries and their application in mode of hybrid electric vehicle. The experiment is focused on the production of electrodes to determine the effect five types of additives in negative active mass in PsoC(Partial State of Charge) mode. This simulates conditions occurring in the mode of hybrid electric vehicles (HEV). Detailed record
	Exploring the influence of pressure on the life of lead acid batteries for hybrid electric vehicles Čech, Tomáš ; Křivík, Petr (referee) ; Bača, Petr (advisor) The goal of the thesis is to study literature and to become familiar with problems of accumulators operating in the mode of hybrid electric vehicles (HEV). To work up problems of a potential impact of the influence on the system of the lead accumulator. Assemble the experimental cells with discontinuous system of parallel fins and to treat them with different operating modes. Then to evaluate the results. Detailed record
	Effect of glass fibers in the lead-acid batteries for hybrid electric vehicles Klojda, Viktor ; Tošer, Pavel (referee) ; Bača, Petr (advisor) Master´s thesis deals with the utilization of lead-acid accumulators in hybrid electric vehicle regime. It describes the side effects known as PCL, generated during PSOC regime and connected with the length of the battery lifespan. One possibility how to eliminate these effects, is the use of additives in active mass of the negative electrode, in the form of glass fibres. The project provides the parametres and reactions of additive, that have lead to the improvement of battery properties. The purpose of this thesis is to verify the positive effect of the aditive on the lifespan of the lead-acid accumulator. Detailed record
	Effect of titanium dioxide on the properties of lead-acid batteries operating in hybrid vehicles mode Konečný, Zdeněk ; Tošer, Pavel (referee) ; Bača, Petr (advisor) This work deals with lead-acid batteries operating in hybrid electric vehicles mode, i.e. in a partial state of charge. The adverse effects such as premature capacity loss and large internal resistance can markedly affect the life of a lead battery. The experiment described in this work aims to clarify the influence of the titanium dioxide in the active mass of negative electrodes especially in the life of lead acid batteries. Detailed record
	Investigation of temperature changes in the lead-acid battery system for hybrid electric vehicles Kadrnka, Petr ; Tošer, Pavel (referee) ; Křivík, Petr (advisor) The lead-acid batteries are most commonly used electrochemical power source. The lead-acid battery is the oldest type of secondary battery cells. This lead-acid batteries have a great use in hybrid electric vehicles (HEVs), which operate in different modes of vehicle operation. This is related to changes in battery temperature, caused by Joule heat taking place during discharging and chargingg the battery in a vehicle operation. The lead-acid batteries in hybrid electric vehicles work in mode PSoC. Detailed record
	Influence of pressure in the lead-acid batteries for hybrid electric vehicles. Svoboda, Marek ; Vaněk, Jiří (referee) ; Bača, Petr (advisor) Lead-acid batteries of hybrid electric vehicles (HEV) are functioning in PSoC regime (Partial State of Charge). In PSoC regime new fail mechanisms occur. These mechanisms usually lead to nonreversible sulphation of negative electrodes. Main aim of this research is to avoid negative electrode sulphation and to improve lifetime of lead-acid accumulators used in HEV. Detailed record
	Investigation causes of the premature capacity loss in accumulator for hybrid electric vehicles Vystrčil, Marek ; Bilko, Radek (referee) ; Bača, Petr (advisor) This thesis describes the results of two successive experiments. The first was focused on the influence of impurities in the active mass of negative electrode in PSoC (Partial State of Charge) mode, which simulates the conditions occurring in HEV (hybrid electric vehicle). In the second experiment, cells with the same additives were exposed to optimum downforce 4N/cm2, by which we wanted to prove the influence of pressure on life of VRLA (Valve Regulated Lead Acid) cells working in operating HEV conditions. Detailed record
	Investigation size effect of negative active mass additive on service life lead-acid accumulator. Mikoláš, Jiří ; Novák, Vítězslav (referee) ; Bača, Petr (advisor) The task of research work is to study new mechanisms and to minimize disturbance of lead batteries for hybrid electric vehicles. Those arising under the PSoC (Partial State of Charge) and is linked to irreversible sulphation mainly negative electrodes. As one solution to prevent sulphation of the negative electrode appears to be the active ingredients in a negative matter. In the investigated electrodes is verified the influence of carbon, titanium dioxide and silica on the grain size of the order of nanometers. Detailed record
