Electric vehicles market is evolving rapidly, introducing a plethora of benefits for modern transportation. In addition, the evolution of lithium-ion batteries technology provide high efficiency and performance with sufficient range. To achieve that, advanced battery management systems monitoring parameters, like state of charge and voltage are required. It is essential to keep the battery cells at optimum state, enhancing their safety functioning and useful lifespan. In this paper, a low cost, unified prototype board is developed and tested for monitoring critical battery information, though logged data analysis. A monitoring system has been implemented to optimize system with constant operation diagnosis and data validation. Total efficiency improvement of 5% was established without advanced API interface. The system proved to be reliable with myriad possibilities, limiting battery stress and degradation. Further …
