Electric vehicle monitoring system by using MATLAB/App Designer

Abstract

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 because it has a limited graphic support and some existing graphics component are not supported yet. The data acquisition has been done using the low-cost platform, NI USB 6001. Thanks to this card, the sensor signals will be transferred to the PC, so the user will be able to know what is happening with the variables to monitor. To measure some variables, the signal from the sensors is adapted to the voltage range of the data acquisition card. The usage of several adapters is therefore necessary in the circuits.
