Měřič kapacity akumulátorů se záznamem na SD kartu

Abstract

This bachelor’s thesis deals with the measurement of battery capacity, which is an important process that is carried out to determine the amount of energy that can be obtained from a given battery. This process is important to ensure the proper functioning of devices that use batteries as a source of energy. Accurate measurement of battery capacity is key to ensuring their optimal use. Correct measurement allows users to identify potential problems in time and thus ensure timely maintenance and possible battery replacement when necessary. The work further deals with the implementation of a program for the ESP32 microcontroller, designed for communication between the electronic load and the ESP32 microcontroller, with which it communicates via the UART interface and subsequent uploading data via serial communication to an SD card. The designed device also includes an OLED display, which informs about the status of the load discharge process.
