Solar Charger
Sygeryč, Daniel ; Tonar, Karel (referee) ; Tošer, Pavel (advisor)
This bachelor’s thesis deals with the charging of the batteries by a solar energy. Great emphasis is placed on maximum utilization of the energy obtained. The development, the principle and characteristics of the photovoltaic cell were described. Next chapter is focused on lead-acid batteries. There are presented the characteristics and principles of their charging. This thesis also deals with the implementation of solar charger using solar controller, switching voltage inverter, Step-Down converter, protective and signaling circuits as well. There is also described the design and calculation of the solar charger circuit board.

Optimalization of pulse charging mode of lead-acid battery
Sygeryč, Daniel ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This thesis deals with pulse charging lead acid batteries. The theoretical part provides the basic electrochemical reactions that take place in the lead pack, then this section discusses important parameters of lead-acid battery, its structure and distribution of the various types depending on the application. The next section describes the theory of charging lead-acid battery. The practical part deals with constructing experimental cells, which are then tested. The subject of the experimental execution and optimization of pulse charging modes in order to find a suitable pulse mode, which reduces the duration of charging, while significantly shorten the life of lead-acid battery.
