On Monday 22/6/2015 at 12:00 in the ceremony hall of the Administration Building in the Technical University of Zografou will be the presentation of the vehicle "Pyrophorus II. "
Η παρουσίαση αποσκοπεί στην information της ακαδημαϊκής κοινότητας και του κοινού για την προσπάθεια ανάπτυξης και την επίδειξη του ερευνητικού οχήματος εξοικονόμησης ενέργειας «Πυρφόρος II» κατασκευασμένο αποκλειστικά από φοιτητές του ΕΜΠ και τη συμμετοχή τους στον ευρωπαϊκό διαγωνισμό ECO-MARATHON 2015.
2015 Pyrmor
The vehicle of the "Prometheus" team of the Department of Electrical and Computer Engineering of the National Technical University of Athens is adapted each time to the high safety requirements of the ECO-MARATHON competition. So the project continues to evolve and at the same time improves.
2 Pyrmoros is a building achievement of our team in preparation for the Shell Eco Marathon 2014 competition as it has successfully and fully embraced our expectations.
The team initially innovated among other things as during duration of this year he designed and built every single part of the car.
Starting from the engine, an innovative permanent magnet engine design was created, which proved to be profitable and ultimately implemented in the electric motor and power electronics lab.
Having as base therefore, the power needs of our new machine, at the same time the power electronics team designed and implemented the dc/dc converter which optimally collects the provided power of the photovoltaic panel permanently located on the roof of the vehicle, as well as the dc/ac inverter which is responsible for providing the necessary drive power to the designed permanent magnet motor.
In addition, the automatic start-up algorithm for energy saving and cruise control has been incorporated to keep the speed fast during the race.
One of the most important additions to our new vehicle is the telemetry system which conveys live important clues during the race such as engine temperature, speed and distance traveled as well as the instantaneous consumption of our vehicle.
So while the time frames were tight, at the same time the engineering sub-group designed and built in the laboratory the chassis and shell of the car as well as the system addresskeeping in mind the safety of the driver but also the flexibility and ergonomics of the vehicle, aiming at the maximum possible weight savings.
