This paper shows the development followed for three different structures of urban light electric vehicles. The first one is based in a Carbon Fiber Reinforced Plastic (CFRP) structure, the second one is a multi-material solution including aluminum, magnesium and structural thermoplastic joined by electromagnetic forces and the third one is based on the use of advanced high strength steel. For the...
This article presents a substantial review of nonlinear memristive circuits based on Zdenek BIOLEK model alonside an innovator design developed within the Hewlett-Packard laboratories. HP realized a physical implementation of memristors by placing two layers of titanium dioxide between two electrodes. The first layer is partially doped with oxygen gaps and behaves like a semiconductor and the second...
In this paper is described a set of constraints applied to a wireless power-supply system (emitter and receiver) for operating in optimal conditions. These constraints regard both geometrical aspects and operational conditions of the system. There is also presented the performance optimization in the power wireless transfer. Starting from the equivalent scheme of a wireless power transfer system sinusoidal...
In the paper it is presented a designing algorithm for decoding the data provided by a two-channel incremental encoder in order to identify the rotation direction. Such information is useful when monitoring the operation status of various driving devices found within a vehicle. The resulting digital circuit is implemented on a FPGA (Field-Programmable Gate Array), which can be easily included as a...
In this paper an optimal strategy for electric vehicle (EV) charging is proposed to achieve the best network operating conditions, with the help of battery energy storage systems (BESS), while integrating photovoltaic power plants (PV). The electric vehicles can both participate in demand response (DR) and serve as energy storage facilities. They can respond to DR signals, such as price variations...
Within the electric mobility concept, the transportation sector found the possibility to reduce the greenhouse gas emissions. Although the reduction of emissions is a target for EU, the transportation sector is mainly dependent on fossil fuels like petroleum or natural gas. Nowadays, the most used power source for land and water vehicles propulsion is the internal combustion engine, but in the latest...
Analyzing the values of public transport systems energy indicators and metropolitan air pollution together with the branch specific economic forecasts, the authorities and suppliers can estimate future trends. To reduce the urban usage of personal automobiles it is needed to increase the proportion of electric public transport vehicles (Tramways, Trolleys, Electric buses), also it needs to increase...
With the increase of pollution in urban areas, in the same time, within the majority of crowded cities, the circulation infrastructure for bicycles, trotters, mopeds, hover boards, etc. has been developed for both classic and electric versions, various models of street furniture for parking and protection being designed and built. To charge the batteries of the these electric vehicles we present within...
An important part of the electric vehicle is the electric power supply. Several types of sources are known, one of which is the Fuel Cell (FC). Its applications range from rockets to household applications. More recently it was suggested that interconnecting the car provided with FC with the home network or even with the power distribution system might solve their recharging problem. On the other...
In order to substantiate some impact studies, the paper presents some considerations regarding the main factors determining the local and global impact on the environment of the autonomy electric transport in comparison with the classic traction by internal combustion engines. The main conclusion of the paper is that from the point of view of the local impact, autonomy electric transport-independent...
Electricity as an energy vector for vehicle propulsion offers the possibility to substitute oil with a wide diversity of primary energy sources. This could ensure security of energy supply and a broad use of renewable and carbon-free energy sources in the transport sector which could help the European Union targets on carbon-dioxide emissions reduction. Electric cars and hybrid cars contain roughly...
The paper presents an advanced modular photovoltaic system designed for Pug-in Small Electric Vehicles (PsEV) electricity supply in remote applications. The concept is based on the modularity of the photovoltaic (PV) power supply system (PVbox) that can be multiplied in order to fully cover the electricity demand of each application. Based on that the interconnection between multiple PVboxes is done...
The present work is focused for the modelling, analysing, and evaluating of the obtained results from the simulation of the electric vehicles demand with “EnergyPLAN”. The models have developed for creating an optimal structure of the energy supply for electrical vehicles useful in Romanian energy system. For reducing greenhouse gas emissions and for decarbonizing the economy in the following period,...
This paper presents an application that will be used in shopping malls. It is an indoor positioning system (IPS) based mobile application. The main idea is providing a win win situation between the customers and stores. It will be utilized in the store or in front of the store with a check in at the store. Thus, the customer will easily reach many offers, product explanations of the considered store...
Wireless power transmission is a special concern of electrical engineering with major implications in the life of society. It is manifested both in the scientific field through the large number of congresses and prestigious journals publications as well as in various practical applications ranging from medical care to robotics, communications and military technique. After a latency of more than 100...
Most of statistics currently show that almost every year a considerable number of accidents are happening due to weather conditions, and with a rate of nearly 78% [1] of them are due to the reflection of sunlight. The motivation of the paper is given by the desire to greatly reduce this percentage by providing assistance to the driver by keeping the conditions for optimum visibility both day and night...
Soft magnetic composites are used in the electrical motors' manufacture and can be considered as magnetic powder particles surrounded by an electrical insulating material. Today there is an interest in bulk soft magnetic composites, because of the high demand for miniaturization of the cores. These materials provide several advantages over classical non-oriented electrical steels. A Somaloy 500 torroidal...
All vehicles produced today must be fitted with an On-Board Diagnostic (OBD) interface. With the help of the OBD a data connection through the Controller Area Network (CAN) is realized with the Engine Control Unit (ECU). This control unit is instrumental in optimizing the engine performance. There are many OBD adapters on the market today, ranging from the cheap Do-It-Yourself kind to expensive, professional...
