چکیده
The on-site assessment of the efficiency a charging station is not trivial process and topic discussion for professionals. electric Vehicle Supply Equipment (EVSE), an important parameter both user EVSE operator. This paper deals with particular type EVSE, using static wireless power transfer (WPT). proposes clear method to account parameters which can affect correct determination efficiency, such as in accuracy meters effect temperature. work define assessment, aimed at clarifying that despite distorted waveforms stations, it possible reach good wide temperature span (expanded uncertainty <0.5% between 5 °C 40 °C). Analysis initiated from measurement conditions actual recorded two WPT EVSEs differently rated power. paves way possibility verifying class 0.5 m on-site, desirable this application. also clarifies evident presence voltage current ripple batteries, weight on total nevertheless lower than 0.1%. Finally, highlights how, ripple, would be advisable calibrate instrumentation DC AC, frequency double working coils.

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

15 صفحه اولPlacement of Loading Stations for Electric Vehicles: No Detours Necessary!
Compared to conventional cars, electric vehicles still suffer from a considerably shorter cruising range. Combined with the sparsity of battery loading stations, the complete transition to E-mobility still seems a long way to go. In this paper, we consider the problem of placing as few loading stations as possible such that on any shortest path there are enough to guarantee sufficient energy su...
متن کاملEquitable Distribution of Recharging Stations for Electric Vehicles
Given the limited driving range of battery electric vehicles and lack of sufficient charging infrastructure, locating charging stations is an important decision problem to enable long-distance travels by battery electric vehicles. This paper considers an important political factor in such location problems: the equitable access to charging stations among geographical regions. We propose three t...
