DEVELOPMENT OF A CIRCUIT FOR MEASURING THE CAPACITANCE OF LI-ION BATTERIES BASED ON THE ARDUINO UNO DEBUG BOARD

The scheme of the device for measuring the capacity of Li-Ion finger batteries вhas been developed. The main element of the scheme is the Arduino Uno debug card. The structure, possibilities, operating principles of this board are investigated. An element base is chosen for the implementation of the device circuit, pinouts are made and the device circuit is obtained as a result of the work. The circuit was assembled and tested in NI Multisim software, a virtual experiment was conducted. As a result of the experiment, a sample was obtained for which metrological characteristics (absolute error, relative error) were calculated. The stages of further work on this project are presented, the result of which is supposed to be one copy of the device in the working welded assembly. In this work, the development of the topic of creating simple devices is traced in the framework of the preparation of bachelors in instrument-making. A wide range of disciplines is used in the course of preparation of bachelors in the direction of 12.03.01 Instrument making: Element base of electronics, Metrology, Electronics in measuring devices, Digital measuring devices.
