STUDY AND MATHEMATICAL MODELING OF A LITHIUM-ION BATTERY

Abstract

This study considers existing methods of mathematical modeling of lithium-ion batteries based on the Shepherd formula, as well as using formulas from the general course of physics. In order to measure experimental data in automatic mode, a special measuring facility was developed, the main element of the setup is a programmable platform based on the ATmega328p microprocessor. It controls the process, measures the voltage on the battery and transmits data to the computer every 5 seconds via the UART interface of the microprocessor for further analysis.
