This paper proposes an improved battery management system (BMS) that provides supervisory monitoring and active cell-to-cell equalization in order to protect the battery lifespan in an electric vehicle (EV). This can be accomplished through a Supercapacitor (SC) bank that can store and then recover electric energy to any weak cell of the EV battery bank. Specifically, the proposed control scheme online...
This article focuses on the creation of a graphical interface which enables the user to monitor the most important variables from the electric vehicle. The App Designer environment from MATLAB has been the main resource used to develop this interface, because it offered an enhanced design environment and an expanded UI component set. At its current development state, it is not a replacement for GUIDE...
In this research, an intelligent lithium-ion battery-charging management system is proposed. The system integrates the battery monitoring and balance platform (BMBP) and charging station. According to the battery information of BMBP and the user needs, a proposed dual charging method (DCM) is used to control the charging voltage or current of charging station. The DCM contains the rapid and the smart...
