Testmetodik för vintertestning av el- och hybridfordon

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new Electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the Electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of Electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and Electric cars.

In recent years, however, a change occurred that may be significant for the electric car and it is now to commercialize in the market of passenger cars. The technology has in recent years elaborated as more car manufacturers have started to invest in development in the subject field. This thesis aims to compile an action plan for the development of charging infrastructure for electric vehicles in Uppsalahem ABs residential areas. It is based on a survey of different residential areas and a survey of charging infrastructure.

Framtidens elbilar utmanar nutidens elnät : Påverkan av ett ökat antal elbilar på ett halländskt elnät

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

Utveckling av affärsmodeller på laddningsmarknaden : En studie av elbilsladdning i Sverige

This paper covers a study of the Swedish charging market for electric vehicles from both the perspective of stakeholders and car owners. By interviewing representatives of four key stakeholders on the market; commercial parkings, malls, service stations and working places, data regarding their business models of today is examined. At present electricity is provided for free, but all stakeholder point out that this business model is not sustainable in the long run. The result of the interviews shows that electricity won?t be offered for free in the future ? the question is which factors affect how long it will take for the different stakeholders to find a suitable business model.

Framtidens elnät : Hur elbilar och solceller påverkar på det lokala elnätet

The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

IT i bilen : En fallstudie av ubikvitär datorisering

This paper aims to study the possibilities and challenges the car industry has to face with applying information technology in cars. The goal is to describe and analyse all the existing technology in the cars out on the market today as well as future possible technologies in cars. By interviewing people who has been working or are working with information technology in cars, we aim to clarify the obstacles and opportunities in the process of implementing informatics in cars. With this knowledge we want to learn more about Ubiquitous computing and how humans interact with Ubiquitous computers today and will be interacting in the future. Technology has a rapid development pace and we find it interesting to examine how the car industry can keep up with the rapid development pace of technology. .

Scenarioanalys över Sveriges elproduktion år 2050 : Kan Sverige försörja sig med 100 % förnybar

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

När ska dieselelektrisk framdrift av fartyg väljas?

Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.

Insatser och åtgärder för främjandet av laddelbilar i Sverige

To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society. The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.

Att köra eller inte köra : En studie av miljömedvetna bilisters dissonansreducerande- och identitetsupprätthållande strategier

Att köra eller inte köra is a qualitative study aiming to show how environmentally conscious people who utilizes cars deal with their dissonant behavior, but at the sametime maintain an identity as environmentally conscious. The study is based on the fact that a third of those who drive cars in the municipality of Växjö would like to decrease their use of cars while at the same time having the infrastructural conditions to utilize other means of transportation. The study investigates inner obstacles in the form of habits and lifestyle, but also the different strategies the motorists use to reduce their cognitive dissonance and maintain a green identity. The indicators show that the reason the majority of the motorists continue to utilize cars is part due to inner obstacles (it's adeeply rooted habit, but also a big part of their lifestyles), part due to that the individuals have defenses for their use of their cars, defenses designed to have a dissonance reducing effect. The indicators also show that the motorists value their family higher than the environment, and in this way they can legitimize many of their car uses.
