Photovoltaic laptop charger with wireless connectivity
 Komár, Josef ; Kratochvíl, Tomáš (referee) ; Kufa, Jan (advisor)
This thesis deals with the design and construction of a photovoltaic charger designed primarily for a laptop. The solar charge controller works using the MPPT (Maximum Power Point Tracking) principle and is controlled by a ESP32 microcontroller. The control algorithm constantly searches for the maximum power point, thus achieving the maximum possible power and efficiency of the PV panel. The produced energy is then stored in the battery system, which has a BMS including protections and cell balancers. The charger includes an adjustable 18 – 22 V output for powering a laptop computer and 5 V output for powering devices via USB. All important parameters (voltages, currents and powers) are sent wirelessly by the charger via Wi-Fi interface.
