Smart Integrative System for the Battery Balance Monitoring

In recent years, the electric vehicle industry and industrial electricity storage facilities have expanded. However, even if the type of batteries used is generally the same (Li-Ion 18650 battery type), the management systems of these batteries are specially designed for each application. This phenomenon leads to an increase of installations' costs and, most of the times, the system design starts from the scratch. This work starts from the need to develop a modular system, easily to be built and maintained, thus designing a complete smart system for monitoring all the component cells of the battery in electric vehicles, electric recreational vehicles or industrial installations. In order to carry out this project, several monitoring alternatives presented in the literature have been considered and a system consisting of 4 individual modules was developed: two modules with different precisions for monitoring the voltages of the component cells of the battery, a module for monitoring the charging or discharging current and a main module that interacts with the user and coordinates the all other modules.
