We develop a model to optimize the location of public fast charging stations for electric vehicles (EVs). A difficulty in planning the placement of charging stations is uncertainty in where EV charging demands appear. For this reason, we use a stochastic flow-capturing location model (SFCLM). A sample-average approximation method and an averaged two-replication procedure are used to solve the p...

This report describes the design, construction and test results of an inductively coupled battery charger for robot power supplies. The system should be capable of charging several robot batteries at once from a contactless charging station. The charger should be capable of providing different charging conditions to several different kinds of battery at once. The system should be capable of cha...

Present handheld devices like Smart phones, can be charged wirelessly using new energy harvesting circuit technique through using the traditional wireless technologies. In this case, Bluetooth with a charging circuit enables a short-range wireless charging of a mobile handheld. This paper present the overview of new process of charging and structure of power charging based on Scotty diode with ...

With an increased number of plug-in electric vehicles (PEVs) on the roads, PEV charging infrastructure is gaining an evermore important role in simultaneously meeting the needs of drivers and those of the local distribution grid. However, the current approach to charging is not well suited to scaling with the PEV market. If PEV adoption continues, charging infrastructure will have to overcome i...

The maximum power point tracking (MPPT) is used in photovoltaic system to maximize the photovoltaic array output power , irrespective of temperature , IR radiation, conditions and electrical characteristics of the load. A new MPPT system is developed consisting of DC to DC converter, which is controlled by microcontroller based unit. There are two charging stages for the proposed PV charger. At...

Electric vehicle routing problems (E-VRPs) are receiving growing attention from the operations research community. Electric vehicles (EVs) differ substantially from internal combustion engine vehicles. In the routing context, the main difference is due to the limited EV autonomy, which can be recuperated at charging stations. These are rather scarce, thus EVs typically have to perform detours t...

Frequency, time and places of charging and discharging have critical impact on the Quality of Experience (QoE) of using Electric Vehicles (EVs). EV charging and discharging scheduling schemes should consider both the QoE of using EV and the load capacity of the power grid. In this paper, we design a traveling plan-aware scheduling scheme for EV charging in driving pattern and a cooperative EV c...

Wireless energy transfer is a promising technology to prolong the lifetime of wireless sensor networks (WSNs), by employing charging vehicles to replenish energy to lifetime-critical sensors. Existing studies on sensor charging assumed that one or multiple charging vehicles being deployed. Such an assumption may have its limitation for a real sensor network. On one hand, it usually is insuffici...
