Desenvolvimento de dispositivo de medição e aquisição de dados para veículo elétrico

Abstract

This paper presents an approach between the techniques applied in the mediation of grandeur power, voltage and temperature, which were included in the data acquisition system member micro controlled proposed, which, in your time, is to, from your data acquisition, contribute to energy efficiency of electric vehicles. In this work was discussed the way it will be make the each sensing greatness, with the purpose of achieving the objectives of the project whereas your application is dedicated to electric vehicle developed in UTFPR - Pato Branco, showing some limitations to the system. In order to achieve better understanding, computational simulations were carried out using the software PSIM®. It was held an implementation of signal conditioning circuits, sensors and hardware, and, with completed circuits, it can produce printed circuit boards. After this, developed the practical experiments, in order to compare them with the simulations, as well as mediation reference instrument, in order to perform a statistical analysis of the error. We conclude, therefore, with this work directed data acquisition for the electric vehicle, at the worst case, approximately 82% of the data of mediation with maximum 2.5% errors, and, in the best case, 99.7% within this deviation, in mediations that endure for nearly two hours.
