This paper proposes a strategy to minimize the losses of an induction motor propelling and Electric Vehicle (EV). The proposed control strategy, based on a Direct Flux and Torque Control (DTC) scheme, utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of the EV to achieve the efficiency optimized(More)
This paper presents system modeling, analysis, and simulation of an electric vehicle (EV) with two independent rear wheel drives. The traction control system is designed to guarantee the EV dynamics and stability when there are no differential gears. Using two in-wheel electric motors makes it possible to have torque and speed control in each wheel. This(More)
The use of an Electric Differential (ED) constitutes a technological advance in vehicle design along with the concept of more electric vehicles. EDs have the advantage of replacing loose and heavy mechanical differentials and transmissions with lighter and smaller electric motors directly coupled to the wheels via a single gear or an in-wheel motor.

This paper presents a new simple dynamic Lithium-Ion battery model. It is modelled by MATLAB/Simulink and SimPowerSystems software packages and simulated at different temperatures, load current, and cycle life number. The interest of this model is the ability to study the behavior of this battery, and improve its life cycle. The model is simple and can be(More)
In this paper a new bidirectional DC-DC converter is proposed to transfer energy between ultra-capacitor and DC bus in electric vehicle. The work presents the average model of this converter. The last model is used to calculate the small signal and transient characteristics of the converter. The derived small signal model can be developed by the transfer(More)
The article aims to simulate a multipowered onboard drive train system. The proposed system is capable of managing and constantly adapting several power sources of different characteristic to a varying current load. All the power sources integrated in the onboard drive train are renewable energy. They include a battery bank, supercapacitors and a fuel cell.(More)
In this paper, a new method for the detection of electrical arc faults is presented It is possible, by using a digital signal processor programmed with Matlab/Simulink, to create a system able to detect the presence of unwanted frequencies in the distribution network. Those frequencies are often generated by an electrical arc in the network.
This paper presents real time fuzzy logic controller (FLC) approach used to design a power management strategy for a hybrid electric vehicle and to protect the battery from overcharging during the repetitive braking energy accumulation. The fuel cell (FC) and battery (B)/supercapacitor (SC) are the primary and secondary power sources, respectively. This(More)
This paper presents system analysis, modeling and simulation of an EV with two independent rear wheel drives. The traction control system is designed to guarantee the EV dynamics and stability in case of no differential gears. Using two electrics in-wheel motors give the possibility to have a torque and speed control in each wheel. This control level(More)
Fuel cell vehicles (FCV's) appear to be one of the viable solutions for the growing concerns for environmental protection and the fast rate of depletion of world oil supply. FCV's can become a viable alternative to the internal combustion engine only if they are able to meet certain reliability, safety, performance, and cost criteria. Improvement of(More)
