With today’s electric charging technology, charging time of an electric vehicle (EV) is much longer than that for a gasoline vehicle, and therefore the queueing effect at an EV charging station (CS) may be serious. That is, when an EV arrives at an overloaded CS, it is likely that the EV will wait for a long time before it is charged. This paper investigates the waiting problem for EV charging....

In multi-hop cellular networks, the existence of a communication link between the mobile station and the base station is not required: a mobile station that has no direct connection with a base station can use other mobile stations as relays. Compared with conventional (single-hop) cellular networks, this new generation can lead to a better usage of the available spectrum and to a reduction of ...

This work deals with the automatic dispatching of charging currents in a station for power-assisted bikes (ebike). The decision variables such as arduousness index and urgency are determined. is carried out from GPS ride data. Urgency calculated using parking time ebike batteries state charge. They used to determine ebike's priorities at continue fuzzy logic. Photovoltaic power forecasting dete...

The demand for Electric Vehicles (EVs) has been exponentially increasing, and to achieve sustainable growth, the industry dictated rapid development of supporting infrastructure. This requires building a reliable EV charging ecosystem that serves customer demands while ensuring security Internet-enabled systems connected critical infrastructure against possible cyber attacks. To this end, we de...

Charging of electric vehicles (EVs) on a large scale can cause problems for the grid. Utilizing local flexibility resources, such as smart charging, stationary battery, vehicle-to-grid applications, and generation be an efficient way to contain grid challenges mitigate need reinforcement. Focusing INSPIRIA charging station located in Norway, this paper investigates possibility coping with immin...

In recent years, an executive number of attacks is to be advanced the power system knowledge that may be able to create an integrity over the world. Wisely The security development of charging stations becomes urgent matters. The attention of smart grid and integrate different technology such as The quality of electric vehicles on the road increases more and more interesting. For example, Charg...

Is battery energy storage a feasible solution for lowering the operational costs of electric vehicle fast charging and reducing its impact on local grids? The thesis project aims at answering this question for the Swedish scenario. The proposed solution (fast charging station coupled with storage) is modelled in MATLAB, and its performance is tested in the framework provided by Swedish regulati...

in this study, an electrostatic sprayer which had been previously designed and constructed was evaluated in order to quantify the charging of droplets. liquid atomization was achieved by using an ultrasonic nozzle. the nozzle maximum flow rate was 25 milliliters per minute and vibration frequency was about 30 khz. the induction method was used for charging the output droplets. all experiments w...
