Under the necessities of reducing emissions and air pollution, and also for increasing fuel economy, automotive companies have been developing electric and plug-in hybrid electric vehicles. This network is used to collect sensor data, which is stored online and manipulated to extract knowledge and generate actions toward energy saving solutions. This paper presents a comparative study of four current control techniques such as hysteresis current controller, Predictive current controller, Proportional Integral controller and Periodic sampling current controller. To assess the behavior of the proposed battery charger under different scenarios of operation, a prototype has been developed, and some simulation and experimental results of the battery charger are presented. Simulation results and system implementation are depicted, and finally, are presented some experimental results obtained with the proposed control system. In this sense, this paper aims to present, in a comprehensive way, the new challenges and opportunities that smart grids are facing, including the new technologies in the vehicle electrification, towards a sustainable future. The functioning of the smart batteries charger is shown through simulation and experimental results, both during the charging G2V and the discharging V2G modes of operation.
This paper describes an intelligent Vehicle to Grid iV2G Charging Platform for plug-in hybrid and electric vehicles that can be used at user's home, and which includes a mobile control system. Both, simulation and experimental, results with different types of mechanical load are presented. The experimental results were obtained using a laboratory test bench. The developed platform prototype is based on the installation of a network of wireless sensors using the emerging Long Range LoRa low power long-range wireless network technology. This platform was developed aiming to test different batteries technologies.
Requiring no specialist engineering knowledge to understand and written in an engaging, accessible style, this is a valuable primer and resource for people in business, policy or study who are keen to understand, encourage and capitalize on the transition to electric mobility. Despite this, their adoption at a large scale has been grindingly slow. Our work proposal is based on the past driving data that are stored in a driver profile, and using real time information about the Electric Vehicle parameters e. Despite this, their adoption at a large scale has been grindingly slow. The batteries charging process is controlled by an appropriate control algorithm, aiming to preserve the batteries lifespan. With this information, it is possible to check if the desirable destination is achievable without a stop to charge the batteries, or even, if to reach the destination it is necessary to perform an optimized driving e.

Besides the normal mode of operation to charge the batteries, denominated Grid-to-Vehicle G2V , in this paper is also discussed the possibility of operation as Vehicle-to-Grid V2G , in which the batteries of the Electric Vehicle return part of the stored energy back to the electrical grid.

The energy broker uses cloud computing paradigm to create a collaborative communication between the involved parts. For that we propose a local energy broker, responsible to handle local energy flow and to exchange energy with 'big' market players, and based on a collaborative approach, to promote user's participation to increase systems knowledge. This paper presents a new approach of pre-defined profiles, based in different voltage and current values, to control the charging and discharging processes of batteries in order to assess their performance. An energy and cost analysis of this concept is performed, which shows that, for the conditions tested, the project is technologically and economically viable, although being highly sensitive to the investment costs and to the electricity market conditions. Besides the results obtained with the batteries, this work also intends to produce results that can contribute to an involvement in the strengthening of the Internet-of-Things. A simulation model was developed using realistic database models of the power semiconductors comprising a nonlinear load with input ac-dc converter, so that the efficiency can be calculated and compared for three distinct cases: 1 load supplied by an ac voltage; 2 load supplied by a dc voltage; 3 load without the input ac-dc converter supplied by a dc voltage. The problem is that once you have gotten your nifty new product, the electric vehicles serra joao vitor fern andes gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging.
Simulation results to assess the performance of the proposed system are also presented. Also in this paper are shown and briefly described the roles of the key concepts related with the Smart Grids in terms of Systems and Functional Areas, Power Electronics Systems, and Electric Mobility. It is considered the current consumed, according to a typical electric consumption profile, and the voltage degradation for a large number of houses. During the G2V operation mode the batteries are charged from the power grid with sinusoidal current and unitary power factor. The paper shows the simulation results and are drawn several conclusions.

Czuczman, Williams Me, M R Heyman, Isabelle Bence-Bruckler, Christine A. To assess the behavior of the presented bidirectional power converter under different scenarios, are presented some computer simulations and experimental results obtained with a prototype that was developed to be integrated in an Electric Vehicle. The E-mail message field is required. In order to overcome this limitation, we propose developing a new solution enabling drivers to drive longer distances. Two commercial different types of battery chargers were considered: a traditional model with highly distorted current consumption that causes distortion in the power grid voltage , and another with almost sinusoidal current consumption. The large dependency of the imported fossil fuels and the soaring oil prices, makes essential the look for alternatives to the traditional people transportation system.
Due to the electrical power distribution network limitation and absence of smart meter devices, Electric Vehicles charging should be performed in a balanced way, taking into account past experience, weather information based on data mining, and simulation approaches.

Nowadays, concerns about climate change have contributed significantly to changing the paradigm in the urban transportation sector towards vehicle electrification, where purely electric or hybrid vehicles are increasingly a new reality, supported by all major automotive brands. The energy broker uses cloud computing paradigm to create a collaborative communication between the involved parts. The proposed equipment presents the advantage of giving good use to the current-source inverter, even when the solar photovoltaic array is not producing energy.
The hardware topologies and the digital control systems of the power converters are evaluated through experimental results obtained with a developed laboratory prototype. Thus, besides the comparison between the ac and dc power grids supplying the same nonlinear load cases 1 and 2 , a third case is considered, which consists of removing the input ac-dc converter eliminating needless components of the nonlinear load when supplied by a dc voltage. This upcoming reality brings the need of the 'old' central energy control to be installed locally. The proposed converter operates with sinusoidal grid current and unitary power factor for all operating power levels. The commercialisation of electric vehicles is expected to instigate an array of new business opportunities for electrical utilities, particularly with the advent of the smart grid. Requiring no specialist engineering knowledge to understand and written in an engaging, accessible style, this is a valuable primer and resource for people in business, policy or study who are keen to understand, encourage and capitalize on the transition to electric mobility. With this increase consumption, how to ensure the balance between supply and demand for electricity at all times? Contributors may also be requested to serve as reviewers for this project.
