Elevated installation costs of the Electric Vehicle Supply Equipments (EVSE) could limit the deployment of charging stations for Electric Vehicles (EVs). In our previous work, we presented a new alternative to expand the network of charging points at a low cost. In the proposed model, the installation costs are reduced by deploying the charging infrastructure over the Public Lighting System (PLS) electric network, which is already deployed. The feasibility of this approach was proven via simulation. The first approach of the model considers a conservative charging strategy. This strategy simulates the arrival of a vehicle in advance in order to assure that when a new connection occurs, the network constraints will still be respected. Therefore, the new vehicles can start charging just after their connection without any problems. However, this approach could limit the performance of the system. The purpose of this work is to study the performance of the charging infrastructure over the PLS when some of the most well known on-line scheduling strategies are implemented. These strategies are characterized by their flexibility for treating the charging processes while respecting the constraints of a low voltage network.

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.

This paper analyzes an 11kW three phase on-board charger in case of prospective high power electric vehicles powered by low voltage traction battery (LV, e.g. 24V or 48V). The charger design is compared to the one in present-day electric passenger vehicles that use high voltage batteries (e.g. Tesla Model S). The analyses show that the main difference appears in the design and operation of the output stage of the isolated DC/DC converter, whereas performance of the PFC stage in both cases is comparable. First, the assessment of differences in the topology choice and in related design considerations is given. Consequently, the selection of semiconductor components for an exemplary topology is presented, followed by the efficiency-to-cost ratio analysis. Although no significant cost change is to be expected in case of LV battery chargers for high power vehicles, the LV system introduces distinguishing advantage by eliminating the need for an isolated HV to LV DC/DC converter, followed by the possibility for the space, loss and cost reduction.

The influence of electric vehicles on the power system has been traditionally analyzed in terms of recharge infrastructures and adequacy of the electric distribution network. Nevertheless, the additional power demand due to the recharge of a large number of batteries could significantly modify the national load profile, hence the dispatching of production plants. The recent literature approaches this issue using deterministic methods or simplified probabilistic considerations. In this framework, the present paper proposes the use of a Monte Carlo probabilistic approach to assess the impact of large fleet of EVs on the efficiency and reliability of the generating park of an electric power system. A Sequential Monte Carlo simulator has been developed and applied to the hourly operation of the Italian power system. Several 2020 scenarios, diversified in terms of number of vehicles and recharge timing, have been assumed for the future fleet of EVs. The study was mainly realized within the PRIME project, funded by the Italian Ministry for the Environment.

Wireless electric vehicle charging will pose an additional strain on existing grid infrastructure. Additionally, dynamic or "on the move" charging schemes may result in increased demand variability due to fragmented charging duration caused by charging lane layouts and traffic. A simulation environment has been set up in order to; assess the impact of dynamic wireless charging on the grid, evaluate energy storage requirements for demand smoothing and finally to explore the possibility of integrating solar energy into the dynamic wireless charging infrastructure.

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.

Hybrid modules have been adopted by vehicle manufacturers to create hybrid variants of existing models. This paper presents the potential performance of an axial flux permanent magnet machine against typical hybrid module design requirements. A multi physics analytical model is implemented and validated experimentally. This is followed by a parametric design study showing that the axial flux topology provides its maximum specific torques and powers within the available package space. Based on the hybrid module design requirements a design is identified for further development and its performance is confirmed through 3D finite element analysis. It is found that in a package space of 300mm diameter and 90mm length (including casings and water jacket) the axial flux topology offers 390Nm and 98kW for lOs, and 159Nm and 66kW continuously. Future work will include full mechanical design and prototyping of the concept.

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.

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.

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.
