Abstract
The paper presents the GRAND HAMSTER ELECTRICWAY 4WD hybrid concept car, developed within the Automotive Engineering Research Centre of the University of Pitesti during 2011, in order to create a green version of Dacia 4WD. The car was built on the mechanical platform of the DACIA DUSTER crossover car, 4x2 versions, by implementing an electric propulsion system in the rear axle. The EcoMatic Hybrid System (Energy conversion with autoMatic Hybrid System) is a diesel-electric version, parallel with two shafts, and plug-in type, organized in a motorized solution E-4WD (Electricway-4WD). The name of the vehicle designates the hybridization obtained with the diesel engine 1.5 litre dCi FAP, 79 kW (107 bhp), placed in the front of the vehicle and the asynchronous electric motor offering a maximum power output of 31kW/42 bhp located at the rear of the vehicle. The traction battery, Lithium Iron Phosphate (LiFePO4) technology, 205V, 12 kWh is rechargeable by the on board single faze charger. The recharging 12V auxiliary battery is realised by a DC/DC converter 205V/12V and is completed by an assembly of the photovoltaic panel placed on the car’s roof .
