High purchase prices of electric vehicles (EV) currently still limit market adoption. Vehicle-to-Grid (V2G) could provide an opportunity to make profit on EV grid connectivity, and thus reduce the Total Cost of Ownership (TCO) in comparison with conventional vehicle technologies. This study is a first step towards integrating V2G benefits in TCO modelling. Our Belgian case study on the city, medium...
The Switched Reluctance Motor (SRM) is a magnetless type of electric motor that has recently received an increasing interest for electric and hybrid vehicle applications. One major advantage of SRMs is that they have the lowest material costs. On the other hand, they suffer from relatively high torque ripples, which can make the motor noisy and less efficient. In this paper, the design and optimization...
This paper presents a comparative study and analysis between various models of Photo-Voltaic (PV) used on solar vehicles, which have been formulated exclusively using the data sheet parameters. The models used in this paper include Single Diode Model, Two-Diode Model, and the Ideal Single Diode Model.
The paper presents the architecture of a new climate-control system that is under development in the XERIC project, funded within the Horizon 2020 EU program, that aims to increase Battery Electric Vehicles (BEVs) autonomy by reducing more than 50% the energy used all over the year for passenger comfort in all weather conditions. The system combines a traditional Vapor Compression Cycle (VCC) with...
Nowadays vehicles have evolved from a mean of transport to something much more complex and powerful. The paradigm change that electric vehicles have brought requires new tools and methodologies for improving not only the way vehicles behave, but also all the elements that are influenced by them. Moreover, electric vehicle are also connected to the Internet, thus they are able to access to a large...
JOSPEL project aims to develop a novel energy efficient climate system for the optimization of interior temperature control management in electrical vehicles through an integrated approach that combines the application of the thermoelectric Joule and Peltier effect, the development of an efficient insulation of the vehicle interior, the energy recovery from heat zones, battery life increase duration...
This paper presents an algorithm for the calculation of maximum slot filling factor in electrical machines. The determination of whole wire cross section that occupy the area of a stator slot is very important in order to estimate the copper losses: the greater is the filling factor the lower are copper losses. The main goal of this paper is to define a simple algorithm for the determination of slot...
Flux observer is a common and practical way to estimate the rotor position and speed for sensorless control of the permanent magnet (PM) AC motors. Currents in the damper cage influent the accuracy of the observed rotor position and speed severely. However, it is really difficult to measure the currents in the damper cage. According to the generation principle of the currents in the damper cage, the...
This paper presents a dynamic torque-frequency characteristic analysis technique for the hybrid stepping motors. Using the model-transformation based method, the static torque-angle characteristic, back-EMF, and parameters of a test motor are simulated. Furthermore, an instantaneous torque prediction technique is proposed. And the dynamic torque-frequency characteristic is analyzed using the numerical...
Renewable distributed generation systems are an alternative solution to provide energy locally near customers. However, the supplying of power without disturbance is the main challenge for utilities, especially for systems that integrate fluctuating renewable sources which can cause voltage sag and swell. In this paper, voltage sag and swell issues are investigated. The first studied scenario is related...
Automobile manufacturers progressively focus on a downsizing strategy to meet the EU's CO2 fleet requirements concerning type approval consumption cycles. The reduction in naturally aspirated engine power due to reduction of displacement is compensated by application of turbocharging.
Reliability and safety issues of the electrical power generation systems becomes more and more popular research topic - especially analysis of the electrical power supply systems operation under fault conditions like e.g. overload or short circuit. Appropriate topology of the rectifier is required to provide stable output voltage and control of the supplied AC current. One of the rectifier topologies...
