Plug-in hybrid vehicle with a lithium iron phosphate battery traction type

Abstract

To promote in the academic environment the ways for reducing global warming produced by the Sport Utility Vehicles, the grand hamster-electric way 4WD concept has developed within the University of Pitesti. It is a Plug-in Hybrid Vehicle powered in electric/hybrid modes by a Lithium Iron Phosphate (LiFePO4) traction battery technology, 205 V, 12 kWh. The concept is developed on the Dacia DUSTER crossover vehicle, 4 × 2 series version by implementing an electric propulsion system in the rear axle. The objective of this project is to realize a 4WD environmentally-friendly vehicle maintaining the leisure of driving the vehicle in the city using the continuously variable transmission (CVT) in the electric mode and the diesel motorization outside of the town in the thermal mode. The architecture is parallel type and E-4WD with a standard diesel engine 1,5 dCi FAP, 79 kW(107 bhp) and 6 speed manual gearbox in the front, and an asynchronous electric motor 31 kW (41 bhp) coupled with the reduction and differential gearbox unit at the rear. The traction battery is monitored by a battery monitor and charged by an embarked charger. The charging and discharging of the battery is authorized by the Battery Management System. The paper presents the firsts performances of the vehicle on the road tests. © 2013 Springer-Verlag.
