In this paper is presented the development of a
project to extract, in real-time, information’s related with an
Electric Vehicle (EV). This project was elaborated to extract data
from an EV battery charging device developed at the University
of Minho, and from an EV prototype, the VEECO (Veículo
Eléctrico ECOlógico – Ecologic Electric Vehicle), developed in a
cooperation project of ISEL (Lisbon Superior Institute of
Engineering) and the Portuguese company VE. The main goal of
this project consists in collecting and transmitting the extracted
data to inform the EV driver about the performance and the real
behavior of the EV. Thereby, it is created an open interface to
manage, in real-time, the main data related with the EV, as the
batteries SoC (State-of-Charge), the EV speed, and internal
temperatures (like the temperatures of the batteries, motor and
power electronics inverter), as well as to control the start and
stop of the batteries charging process, and to optimize the
charging program (to define the best algorithm to preserve the
batteries lifespan). This interface also controls the discharging
process of the batteries, in order to make possible to deliver back
to the electrical power grid part of the stored energy in the
batteries, which is defined by the concept Vehicle-to-Grid (V2G).
In the paper are presented and described the two main parts of
this work: the real-time information extraction system and the
charging device.FEDER Funds - Operational Programme for Competitiveness Factors (COMPETE)Fundação para a Ciência e a Tecnologia (FCT) - PTDC/EEA-EEL/104569/2008, MITPT/EDAM-SMS/0030/2008
