Passive three-phase rectifier circuits are very popular for ac-dc power conversion. However, they do not have the capability to reverse the power flow, which is demanded by some recent potential smart-grid applications, such as vehicle-togrid (V2G) power transfer. This paper compares two structures of reversible battery chargers, i.e., an interleaved dc-dc converter fed by a three-phase power factor corrector rectifier and a three-phase ac-dc matrix converter, which may be suitable for plug-in electric vehicles. The comparison aims to estimate the power losses, the power capability and the size of the converters under common requirements.

The electrification of the light vehicle fleets would be a reality in the coming decades. It is being studied through pilot experiences and surveys, how this change in the technology would affect the users driving behaviour. Obviously, new challenges appear, for instance the battery charging, which would be certainly different to the current needs and timings for filling up the internal combustion engine vehicles tanks. Analysis of real electric vehicle usage data is a key point in the development of the electric mobility. A large collection of electric vehicles and charging points have been monitored during three years and the results about the driving and charging patterns are shown in this work. These results may help to develop future charging infrastructure location and to evaluate the electric vehicle integration into the grid.

Charging infrastructures have a fundamental role in the diffusion of Electrical Vehicles (EVs). An insufficient number of these could have negative effects on the EVs diffusion. This paper is going to analyze the Italian territory in order to provide an evaluation regarding the number of charging stations that Italian highways need. First of all attention was paid about the number of electrical vehicles situated in each Italian regions. Then, a cartographic study of the territory followed in order to identify the highways network and the traffic flow in it and a study of the main characteristics of the EVs over the past few years was carried. Finally, simulation results have demonstrated that the developed method supports the evaluation about the number of the charging stations that the Italian highways need.

Recent advances in the automotive industry have incorporated the latest technology in vehicle electrification, with the aim to reduce fuel consumption, pollutants emissions, as well as enhance vehicle performance and safety. As a result, Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) have become the imminent automotive future, establishing important challenges in vehicle systems integration and control. In these vehicles, the regenerative braking is currently the major technique of energy recovery, providing accurate control on the brake torque applied. However regenerative brakes still need the support of conventional friction brakes, mainly due to the battery limitations. Consequently, the coordination of both braking strategies becomes critical for the safe actuation of braking related systems such as: ABS and ESP. Unfortunately, the torque blending between friction and regenerative brakes is a complicated task due to the different systems inputs; the regenerative brakes receive torque inputs, whilst the friction brakes work with pressure inputs. This paper proposes the friction brake torque estimation to simplify the torque blending, and improve the energy recovery and driving safety. The brake torque is estimated not only considering the pressure developed at the calipers, but also the brake disc temperature, and the wheel speed effect on the friction coefficient. The torque is obtained without installing additional sensors in the vehicle platform, considering that only wheel speed sensors are available. The estimation is performed using the extended version of the Kalman Filter. The results obtained are very satisfactory, and can improve the performance of the named systems in a safe way.

Inductive Wireless Power Transfer (WPT) is advantageously used to charge the battery pack of the electric vehicles (EVs). The key component of any inductive WPT system is the coupling setup of the two coils, one buried in the road pavement and the other one embedded into the EV, since it plays an important role in the power transfer. This paper refers to the study case of a WPT system for charging the battery pack of an electric city-car and evaluates the inductive characteristics of different coil-coupling setups. The evaluation begins with a formula-based approach and continues with a computer-assisted analysis of the coil-coupling inductive parameters. The evaluation includes the study of the dependence of the parameters on coil distance, axial misalignment, and turn distance. The outcomes of the analysis are used to compare various coil-coupling setups in view of the implementation of a WPT system in the electric city-car of the study case.

The European Commission introduced carbon dioxide emission standards on cars as an obligation to manufacturers in an aim to reduce carbon footprint of passenger cars in EU transportation. Car industry adjusting to a standard targeting 95 gCO2/km by 2020 is already marketing increasingly low CO2 emitting technologies. In the context of a strong emission cut strategy until 2050 the EU could adopt CO2 car standards at the levels of 20 gCO2/km. The aim of this paper is to explore more optimistic CO2 targets on passenger cars in the medium and the long term by using the PRIMES-TREMOVE energy economic transport model covering the EU-27 countries. In our study, we quantify two policy scenarios implementing more optimistic carbon emission targets at a different pace and we derive policy conclusions in terms of costs, emissions and energy by comparing them with a Reference scenario. The analysis shows a restructuring of the EU car fleet, leading to significant reductions in CO2 emissions and fuel consumption driven by a high penetration of advanced vehicle technologies in the long term. We find that if policymakers intend to pursue more optimistic carbon emission standards then the advanced vehicle technologies will prevail, albeit at an increase in user costs. CO2 emission targets can potentially be a key policy towards sustainable low carbon EU road private passenger transportation, if a decarbonisation strategy is employed.

We have developed a next generation capacitor named Nano-hybrid capacitor (NBC), which uses a completely new lithium titanium oxide (LTO)-based negative electrode material comprising of nano-crystalline LTO grafted onto carbon nano-fibers (nano-LTO/CNF composite). The nano-LTO/CNF composite is simply prepared by using “Nano-hybrid technique”. The NBC has realized higher energy performance than electric double layer capacitor (EDLC) as a conventional capacitor, maintaining a good power performance as high as the EDLC.

In this paper a simple topology for electronic differential in an electric vehicle with four independent In-wheel motors is proposed. Based on inputs of the steering wheel angle and the acceleration pedal position, this method uses real-time power management and produces different torque references for the four wheels and, consequently the angular velocity of each wheel will be adjusted. Using slip-ratio calculations the proposed algorithm extracts maximum output torque by optimizing the operating-point slip ratio. The paper also highlights an application of deployed in-wheel motors in yaw stability and suggests a simple yaw control strategy. The proposed electronic differential method is first investigated using MATLAB and is then implemented on a real-time digital simulator, which is then connected to a small motor to verify its performance in a hardware-in-loop scheme.

Our team is currently the global technology leader in the field of both carbon-carbon ultracapacitors and hybrid lithium-carbon devices. Main expertise includes R&D in material science, electrochemistry, process engineering, manufacturing engineering, electrical system design and manufacture of ultracapacitor electrodes, cells and modules. The team participated in a number of international research projects, and prototypes of ultracapacitors and hybrids were tested in the Institute of Transportation Studies, UC Davis, in JME Inc., in Wayne State University, and some other labs. All the test results confirm the superlative performance of the devices developed: carbon-carbon ultracapacitors demonstrate the extremely low inner resistance resulting in the highest power capability and efficiency that also reduces the cooling requirements and improves safety. Our “parallel” hybrid devices demonstrate substantially higher energy and power density than competing LIC technologies. In order to make ultracapacitor technology even more attractive to automakers, new organic electrolytes have been developed and are currently under testing (not ionic liquids) at temperatures about 100 °C and voltages up to 3.0 V.

Fuel Cells (FC) are widely investigated for their potential use in electric transportation due of their capability to provide significant amounts of energy with low-noise and with almost zero-emission. FC-based power sources are non-linear system with low voltage and high current capabilities and with efficiency close to 50%. Several researches are in progress, aiming at increasing overall efficiency through optimised combination of components, mainly the FC and the DC/DC converter necessary for its interface with the vehicle DC bus or the recharging station. In this paper, a novel and efficient power system architecture suitable for fuel cell powered vehicles and for recharging stations is proposed. The proposed system includes a fuel cell stack and a LLC resonant DC/DC converter with step-up capability. The latter due its to soft switching operations ensures enhanced efficiency over conventional hard switching counterpart. The proposed system has been modeled in a mixed PSIM-MATLAB/Simulink environment; design criteria and procedures are discussed for further applications and simulation results are shown to validate the proposed solution.
