Resumen

In recent decades, the world has witnessed a significant increase in population growth rates, bringing the number of people living on the planet to over 8 billion. This growing number of people, along with the development of large urban centers, has resulted in a gigantic vehicle fleet, most of them powered by internal combustion engines, which operate by burning fossil fuels and generate polluting greenhouse gases such as carbon dioxide (CO2) and methane (CH - 4). In this scenario, the generalized demand for more sustainable transportation alternatives has led vehicle manufacturers to seek to reduce the emission of pollutants by producing electric and hybrid vehicles. In this type of vehicle, the propulsion system is based on electric motors and batteries. A battery management system (BMS) is required to increase vehicle safety further. The BMS can measure parameters such as voltage, current, and temperature of the battery cells and calculate important information such as the State of Charge (SoC), State of Health (SoH), among others. Thus, this work sought to develop the hardware and software of a BMS, using as reference the BQ76PL455A-Q1 integrated circuit produced by Texas Instruments, implemented for monitoring the cells used in an accumulator of a standard competition electric vehicle SAE formula.
