Selected Results of the Scientific Accompanying Research of the E-Mobility Model Region “e-pendler in nieder¨osterreich” (AUSTRIA)

Abstract

This paper describes selected results of the scientific accompanying research of the e-mobility model region "e-pendler in niederösterreich" which is a co-financed model region of the Climate and Energy Fund in Austria and the province of Lower Austria. The purpose of the project is to evaluate the usability of electric vehicles for commuters in Austria. For this, a group of thirty-seven participants were analyzed. With the derived charging profiles and traffic analysis important statements for future problems are possible.The research is divided into three parts. First of all, the commuters' behavior is considered. As second part specific charging profiles are analyzed and the effect of the charging power on the switching point (change from constant current phase to constant voltage phase) is shown. At last the impact of the EV's on the distribution grid is investigated.

Big Data and Discrete Optimization for Electric Urban Bus Operations

“…According to different studies and advice from the manufacturers in their manuals, this increases the battery life ( 33 – 35 ). A useful side effect from this is that the charging behavior in this range can be assumed to be linear ( 36 ), which reduces the complexity of our model. We assumed in our model that all buses use overhead charging, and this is the case for our project.…”

Integration der Ladeinfrastruktur in das elektrische Energiesystem

“…Abhängig vom hinterlegten Ladeverfahren für den Fahrzeugakkumulator sind die angesprochenen Faktoren die Umgebungs-bzw. die Zelltemperatur des Akkumulators, die maximale Ladeleistung mit welcher der Akkumulator geladen werden kann und der aktuelle Ladezustand (SOC -State Of Charge) [8].…”
