The aim of this thesis is to investigate the Electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total Electric solar potential for the region.The Electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

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.

The project was carried out together with OC Off Course who manufactureand distribute mainly Electric bikes.In today?s society, alternative sources of transportation becomes more andmore present and several bicycle sharing programs arises in major citiesacross the world every year.Something that doesn?t exist too much as of yet is bike sharing programsthat uses Electric bikes. An Electric bike is a convenient way oftransportation as well as a good way of avoiding traffic. With an Electricbike you avoid having to sweat when biking over hills or when you need totravel over longer distances.The goal of this project is to develop a bike sharing station according tothe functions need to be met.This thesis Is based on Fredy Olsson´s methods principkonstruktion aswell as a couple of concept generating methods from Kenneth Österlin.From this, a number of sketches were made that later was evaluated inseveral steps in conjunction to a set of specifications. A 3D model of theselected concept was later made in CatiaV5 for a complete product..

Distributed, renewable generation-units and more efficient use of Electric power,demands a developed Electric grid. This grid is often referred to as the ?Smart Grid?.This future Electric system rise expectations among actors in the existing Electricmarket. International organizations share visions of opportunities for Electricityconsumers and new actors, ready to enter the market. At the same time, Electricutility companies may question the need for some of these upcoming changes, as theyare sometimes expected to lead the development.This paper therefore seeks to investigate the business opportunities related to SmartGrids.

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.

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish Electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the Electric and the credit market. The risk model used is Cost-at-Risk which is usually used by public authorities for analysing the risk involved with national debt.

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.

This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new Electric motors for AtlasCopcos Electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an Electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless Electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

                                  The study aimed to explore how patients with ICDs experience their quality of life with a focus on everyday life, Electric shocks, and how support from the health service is perceived. The studydesign is descriptive with a qualitative approach. Semi-structured interviews were conducted with seven patients. Data collection lasted for three weeks and interviews were conducted in the participant´s homes, at the participants? workplaces or over the phone.The study shows that most participants have learned to live with the ICD.

Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and Electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.

This thesis is a feasibility study for a future product development project.

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of Electrical energy. In the USA 9 % of the households Electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential Electricity consumption in Sweden is used drying and washing clothes.

The batteries are exchanged by a specially designed trolley that isinserted under the battery module.

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for Electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.
