Sapienza Università di Roma – Fast Charge 2013 Formula SAE Design Report
No full textFast Charge is the Formula SAE Full Electric team of Sapienza University of Rome. Fast Charge born in 2012 from the heritage of TUSCIA Reparto Corse and thanks to the collaboration and support of ENEL, SCIRE, CTL and ENEA. The team, composed by more than 20 young engineers, focused its design activity in the optimization of powertrain and rolling chassis, in order to obtain a lightweight full electric racing car. A careful design of the storage system has been performed, combining a sizing strategy tailored on endurance real data with a “smart” cooling system. The main specifications in 2013 of the Fast Charge car consist of: optimized steel tube chassis, single YASA DD500 electric motor with SEVCON Evolution 5 drive, EIG 20Ah lithium-ion cells with plastic case, modular battery modules air cooling system with electronic management, aluminum wheel group, limited slip differential, data logging system with thermocouples on all cells and a complete set of sensors for car vehicle dynamics and finally, carbon fiber bodywork for an overall car weight of 230 kg, 85 kW @ 400V and 1500 Nm @ wheels
Formula Student Combustion car 2011
No full textPOMOS Reparto Corse participates to
Formula SAE since 2009 and took part in
European official events in 2010 with
encouraging results that have allowed
placements higher than at the debut season.
The 2011 project maintains the philosophy
set in 2009 trying to perfect the downside of
cars 2009 and 2010. In particular, continuing
the process of lightening that began in 2010
(car 2010 of about 50 kg lighter than the
2009 car), advanced engineering solutions
have adopted to further reduce the weight of
30 kg, reaching the level of the best cars with
4-cylinder engine and steel space frame.
In summary therefore the main specifications
in 2011 of POMOS RC car has optimized steel
tube chassis, Honda CBR F Sport, intake
manifolds in carbon fiber and aluminum and
exhaust in titanium, aluminum wheel groups,
lighter shafts with joints Tripod, limited slip
differential, data logging system with the
thermocouple reading engine exhaust,
carbon fiber bodywork

The main specifications in 2012 of the TUSCIA RC car consist of: optimized steel tube chassis, Honda CBR F Sport engine, intake manifolds in Polyamide nylon and exhaust manifolds in titanium, aluminum wheel group, lighter shafts with tri-pod joints, limited slip differential, data logging system with the thermocouples on exhaust manifold and a complete set of sensors for car vehicle dynamics and finally, carbon fiber bodywork for an overall car weight of 220 kg, 60 kW @ 11.500 rpm and 58 Nm @ 8.000 rpm
Urbe-Enea project for a low consumption urban vehicle
No full textIn 2006 the Hybrid and Electric Research Group of ENEA planned the realization of an hybrid powertrain suitable for small city car (“quadriciclo leggero” for Italian homologation rules) able to fulfil the 350 kg limit for the overall vehicle weight (comprehensive of storage system) imposed by legislation. To fulfil the project, ENEA asks to Sapienza University of Rome to collaborate to the project for the i.c. engine optimisation, rolling chassis design, and hybrid powertrain control, and to University ROMA TRE to collaborate for the electric machines and converters. The main targets of the project, called “Urb-e”, are to realise a powertrain able to achieve low fuel consumption (2.5 litre/ 100 km), low emissions (comparable to EURO 5 rules), together with simple configuration and low powertrain cost
"Bizzarrini P538 Eco Targa" Project
No full textThe project "Bizzarrini P538 Eco Targa" has been developed by the INFOCOM department of " Sapienza" University of Rome. The project consisted in the design and construction of a replica of a historic Italian car, updated with LPG fuel and with modern parallel hybrid-type plug-in technologies, with a start and stop system, and a Lithiumpolymer battery storage system. The research aimed at undertaking practical experimentation on parallel hybrid vehicles, with a special focus on the problems related to the construction and optimization of hybrid propulsion systems. The prototype constructed is made of a space-frame chassis, which is composed of tubular sections of various thicknesses and Fe360 material, with double wishbone with push rod as suspension system. The internal combustion engine is mounted at the rear axle. It is petrol engine 2.2 JTS with direct injection with 185 Hp and 225 Nm. The electric motor, together with its electronic control, is at the front axle, and the motor is a brushless type with 22 kW of power rating and 45 kW of peak power. The electric motor is powered to 222 Vdc from a storage system made of lithium polymer batteries produced by Kokam, with 6.68 kWh of stored energy. A PC/104 embedded pc type has been used as main controller of the hybrid system. The control unit not only supervises and controls the hybrid traction, but enables the display of all operational information of the prototype on a screen positioned within the prototype itself. The simulation model was obtained by coupling the simulation software vehicle dynamics GT-Drive with the Matlab / Simulink environment, to optimize control strategy of the prototype
