This paper deals with an online evaluation tool for application of electric vehicles for everyday utilization. The tool takes respect of the user defined range demands as well as the possible charging periods required due to the battery. In addition, customer parameters such as the load capacity and number of seats are taken into account. The tool is able to not only evaluate pure battery electric...
The fear of climate change encourages countries to work internationally on common plans to try stop the world wide temperature rise, as was seen in 2015 on the “United Nations Framework Convention on Climate Change, 21st Conference of the Parties”. The main objective is to avoid emission of greenhouse gases. Traffic is one major source of greenhouse gas emissions, however this sector offers deployment...
The optimization of the braking energy recovery helps to enlarge the range of an electric vehicle without an extension of the accumulator capacity. In currently available electric vehicles different recuperation strategies with diverse possibilities of activation are implemented. In this paper, several recuperation strategies are illustrated and discussed. Based on a simulation model energy savings...
Dimensioning the battery capacity for any kind of electric vehicle a compromise between electric range and costs has to be found. Therefore it is important for manufacturers to obtain characteristic values and profiles concerning user behavior, e.g. average daily driven distances, based on real life data. In this paper, corresponding results of a field test with extended range electric vehicles in...
Electric vehicles (EVs) and their application raise new questions and pose many new demands. Accordingly, the increasing amount of charging processes by EVs is a new and growing impact on the grid load. In order to deal with this impact and the resulting demands, load shifting allows the grid load to be adjusted. Taking this into consideration this paper initially analyzes, based on field test measurements,...
Electric vehicles (EVs) can help to decrease the emissions in the transport sector, especially in combination with an increase of renewable energies. However, for most of the people the comparably small range of EVs is still an obstacle concerning buying an EV. In this paper a project with a fleet test in the Ruhr-Area of Germany dealing with technologies for long distance electromobility is introduced...
Electric vehicles (EVs) and their application raise new questions and demands. Accordingly, the charging process of electric vehicles is a novelty in everyday life when using such vehicles. This paper presents results of user charging behavior within a field test. In the field test, 500 people with above average yearly mileage took part in integrating the vehicles into their everyday lives. The differences...
Electric vehicles (EVs) can help to decrease the emissions in the transport sector, especially in combination with an increase in renewable energies. However, the comparably small range of available EVs still prevents a higher volume of sales. In a fleet test in the Ruhr-Area of Germany, technologies for long distance electromobility, namely EVs with DC high power charging capability and EVs with...
Extended range electric vehicles offer the possibility to generate electrical energy with a setup of combustion engine and generator when the state of charge of the traction battery is low. As a result, the overall range can be extended to familiar values. The dimensioning of the purely electric range, i.e. the possible cruising range without use of the combustion engine, has much influence on the...
Most of the recent studies dealing with electric vehicles (EV) are based on assumptions in order to describe the behaviours of EV. To enhance the precision of these studies, data sets from real measurements are required. This paper shows EV consumptions which are based on measurements from a field test. This field test was realised with over 500 testing people who are a representative group for a...
As the cruising range is one of the main disadvantages of fully electric vehicles compared to vehicles with combustion engines, its improvement is an important research challenge momentarily. The recuperation of the braking energy is one research approach. In this paper, the theoretical potential of recuperation is discussed and a survey of recuperation strategies is presented. The recuperation energy...
Improvement on the cruising range is one of the main research challenges regarding fully electric vehicles, as the comparably low range is seen as one of the major disadvantages and therefore prevents sales. An optimised recuperation strategy can help to increase the range without an extension of the accumulator capacity. In this paper the possible range depending on various trip situations in (a)...
The low range is one main reason for the low sales volume of fully electric vehicles. With extended range electric vehicles it is possible to generate electrical energy with a setup of combustion engine and generator when the state of charge of the traction battery is low. As a result, the overall range can be extended to familiar values. The dimensioning of the purely electric range, i.e. the possible...

This paper proposes a novel electric differential concept for electric vehicles with distributed motors as a substituion of the mechanical differential gear. Motion models and options for the design of the powertrain are reviewed. Existing concepts of electric differential implementations are presented and structured into two main categories. Based on this, a new powertrain and electric differential...
