Regenerative braking potencial and energy simulations for a plug-in hybrid elec...
Martins, Luís Barreiros; Brito, J. M. O.; Rocha, A. M. D.; Martins, JorgeThere are several possible configurations and technologies for the powertrains of electric and hybrid vehicles, but most of them will include advanced energy storage systems comprising batteries and ultra-capacitors. Thus, it will be of capital importance to evaluate the power and energy involved in braking and the fraction that has the possibility of being regenerated. The Series type Plug-in Hybrid Electric V...
Electric vehicle communities for electric market
Ferreira, João C.; Afonso, João L.In this work is proposed the design of a system to create and handle an Electric Vehicle (EV) community, based on social networks collaborative approach and a credit mechanism to incentive participation and mechanism to incentive participation and divide profits. This system is part of a V2G (Vehicle-to-Grid) module that allows EV owners to be aggregated in communities and participate in the electricity market....
Thermoelectric exhaust energy recovery with temperature control through heat pipes
Martins, Jorge; Brito, F. P.; Gonçalves, L. M.; Antunes, JoaquimCurrently, a great deal of the automotive industry’s R&D effort is focused on improving overall vehicle environmental and energy efficiency. For instance, one of the things that Electric Vehicles (EVs) and Hybrid cars (HEV) have in common is the recovery of waste energy, namely during braking. But, when an I.C. engine is operating (e. g. as a range extender in an EV), a large amount of energy is also wasted wit...
Comparison of charging systems for electric vehicles and their impact on electr...
Monteiro, Vítor Duarte Fernandes; Ferreira, João C.; Pinto, J. G.; Exposto, Bruno Fernandes; Pedrosa, Delfim Duarte Rolo; Afonso, João L.This paper presents a comparison of four types of on-board batteries charging systems for Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs), and their impact on the power quality of the electrical power grid. In the comparison are analyzed the features, the characteristics and the operation of each charging system, aiming their controllability and their impact on the electrical grid, mainly c...
OnBoard reconfigurable battery charger for electric vehicles with traction-to-a...
Pinto, J. G.; Monteiro, Vítor Duarte Fernandes; Gonçalves, Henrique; Afonso, João L.This paper proposes a single-phase reconfigurable battery charger for Electric Vehicle (EV) that operates in three different modes: Grid-to-Vehicle (G2V) mode, in which the traction batteries are charged from the power grid; Vehicle-to-Grid (V2G) mode, in which the traction batteries deliver part of the stored energy back to the power grid; and in Traction-to-Auxiliary (T2A) mode, in which the auxiliary battery...

Thermal characterization of polyhydroxyalkanoates and poly(lactic acid) blends ...
Loureiro, Nuno Calçada; Ghosh, Satyabrata; Viana, J. C.; Esteves, José LuisIn this work we present the thermal characterization of the full scope of polyhydroxyalcanoate and poly(lactic acid) blends obtain by injection molding. Blends of polyhydroxyalcanoate and poly(lactic acid) (PHA/PLA) were prepared in different compositions ranging from 0–100% in steps of 10%. The blends were injection molded and then characterized by differential scanning calorimetry (DSC), scanning electron mic...

Cunha, Álvaro; Brito, F.P.; Martins, Jorge; Rodrigues, Nuno Miguel Feixa; Monteiro, Vítor Duarte Fernandes; Afonso, João L.; Ferreira, Paula VarandasA network of conveniently located fast charging stations is one of the possibilities to facilitate the adoption of Electric Vehicles (EVs). This paper assesses the use of fast charging stations for EVs in conjunction with VRFBs (Vanadium Redox Flow Batteries). These batteries are charged during low electricity demand periods and then supply electricity for the fast charging of EVs during day, thus implementing ...
Energy rating methodology for light-duty vehicles: geographical impact
Marques, Sara; Reis, Luis; Afonso, João L.; Silva, CarlaThe aim of this paper was to describe a new energy dependency score methodology and its consequent application to cars sold in twelve regions: Europe (EU-28) and eleven specific countries worldwide (Australia, Brazil, China, India, Japan, Norway, Portugal, Russia, Saudi Arabia, South Africa and USA). This methodology was developed as a potential tool to inform consumers of their choice impact on the country’s e...
