Research in the field of electric and hybrid mobility at the university of pitesti - the 4x4 electric duster project

The paper presents the electric concept 4WD type, DUSTER Z.E.RO 4WD developed within the Alternative Propulsion Systems for Electric and Hybrid Vehicles laboratory, from Automotive Engineering Research Centre, University of Pitesti, in order to create a green and versatile electric all-wheel drive. This concept car was built on the platform DACIA DUSTER 4WD by implementing a new electric equipment that contains Renault ZE components already launched on the market for commercialized vehicles: Renault Kangoo Z.E and Renault Fluence Z.E. The electric drive, mono-motor type includes a synchronous electric motor type placed transversely, 44 kW, a gears’ reducer with two speeds: L- Low for all terrain and H- High for the road and a mechanical all-wheel drive system. The driver to choose from three different driving modes: 2WD front-wheel drive, Auto, in which the rear-wheel drive is engaged automatically and Lock, whereby 50 % of torque is consistently fed through the rear axle. The traction battery is lithium-ion, Lithium ion Manganese Oxide (LMO) type, 400 V, 22 kWh. The estimated performances are: maximum speed: 130 km/h; autonomy NEDC (New European Driving Cycle): 130 km; standard charging: 6 to 8 hrs with home WALL BOX
