Abstract :The development of Electric Vehicles (EVs) has also accelerated the advancement of battery technology. A Battery Management System (BMS) is essential to use batteries in EVs safely and efficiently. The basic functions of a BMS include measurement, monitoring, and balancing. In the rapidly growing field of micromobility, achieving cost-effective balancing requires high-accuracy measurements. In this study, a BMS design was made with a Nuvoton NUC131 microcontroller for CERYAN, an L6e light electric vehicle, and was evaluated in terms of measurement, performance, and cost. As a result, Since the unit cost of the Nuvoton microcontroller is approximately 30% cheaper compared to STM32Fx, one of the most used microcontrollers, the unit cost of the designed BMS prototype is 27% cheaper. In addition, the ADC measurement error is approximately 0.7 mV, which allows accurate measurement of cell voltages and efficient balancing.
