Using lead-acid accumulators in hybrid electric vehicle regime
Klojda, Viktor ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
This bachelor´s thesis is focused on utilization of maintenance-free lead-acid accumulators in hybrid electric vehicle regime. It describes paralel and serial draft of hybrid vehicles, their function, advantages and disadvantages. It compares lead-acid accumulators with other sorts of primary, secondary and fuel cells. Purpose of this thesis is to improve the lifetime of lead-acid batteries in PSOC regime and accompanying addition use, as an activ material of negative electrode.

Influence of conductive ceramics on the life of lead acid batteries
Tobolák, Jakub ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
This thesis is focused on lead-acid batteries used in hybrid electric vehicles. These cells work in specific conditions, particularly under partial charge referred to as PSOC. This fact is responsible for the premature loss of capacity cell lead-acid batteries and their short lifetime. The task of this thesis is to examine the effect of conductive ceramics as possible additives to the negative electrode active materials of lead-acid battery cells operating in a PSOC, in order to prolong their life.

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.
