Abstract
In today's world, green energy is becoming increasingly important. Due to air pollution, electric vehicles are currently the greatest option for the environment, personal and public transportation. Electric vehicles need batteries, which might be hazardous if they are not used in a safe atmosphere. The purpose of this work is to develop a battery management system (BMS) prototype that can track the voltages, currents, and cell balancing of each cell in a battery pack, as well as the temperature of the pack. The batteries in electric vehicles must always be kept under control within their operational safety area (SOA). To achieve the desired voltage and capacity, multiple battery cells are joined. A huge number of cells are necessary to provide the high voltage and capacity required for electric vehicles. This paper developed methods for monitoring each battery cell's functionality and Algorithms for detecting bad cells for replacement in the battery pack and displaying those cells condition on the monitor whether they are good or bad to notify the users, the current conditions of each cell for the user's next line of action. The experiment was carried out using STM32 microcontrollers.
