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.
Exploring the influence of pressure on the life of lead acid batteries for hybrid electric vehicles
Pospíchal, Martin ; Tošer, Pavel (referee) ; Bača, Petr (advisor)
The lead-acid batteries used in hybrid electronic vehicles HEV operate in high-rate mode in a state of partial charge PSoC. It occurs when the degradation mechanisms related to irreversible sulphation and negative electrodes are a limiting factor in the life of lead-acid batteries. The electrode system was applied to experimental pressure cells of different sizes. Exp. cells were subjected to measurement and evaluation of potential negative electrode, a negative active mass resistance, contact resistance of transition collector - the active mass with the evaluation and measurement of pressure fluctuations within four PSoC runs.
Automatized measuring apparatus for lead acid battery cells
Čapek, Ivo ; Lábus, Radek (referee) ; Křivík, Petr (advisor)
This presented work deals with the development of an automated station for the measuring of experimental cells of the Lead Acid Battery. The principle is to design a measuring station and make programs for cycling of cells in standard and PSoC modes.
