Solar panel power convertor controled by microcontroler

Bakalářská práce je zaměřena na návrh spínaného zdroje. Cílem této práce je dobíjet autobaterii ze solárního panelu. Pro dobíjení autobaterie je potřeba měnit napětí. Pro změnu napětí použijeme měnič, který řídíme pomocí mikrokontroléru. Řízení měniče je realizováno podle naměřených vstupních a výstupních veličin.ObhájenoBachelor thesis is focused on the design of switched mode power supply. The goal of this thesis is charging the automotive battery from a solar panel. For managing the recharge is necessary changing the voltage. For the changing the voltage we use the converter that is controlled by the microcontroller. The controlling of the converter is realised by the measuring of inputs and outputs

Comparison of active and passive battery balancing

The presented BMS is universal and can be used for most applications using a combination of 15 LiFePo4 type accumulators, which are the most often accumulator type in home battery storage systems. Therefore, the presented system is intended for home battery storage by default. This paper focuses on comparison of two most common balancers for equalizing accumulated charge in cells. The systems are compared with each other in terms of efficiency, complexity and the time required to balance the accumulator
