The project Easy Battery Handling - EBH has been carried out in our auspicial and completed for Devantini Corporation, a development company in Halmstad with its main concern in environmental friendly innovations. EBH has solved one of many technical challenges in one of Devantini corporation’s larger projects. This main project involves the development of an electric powered formula racing car. The part of this car that involved EBH was the battery handling to guarantee safe and quick battery exchanges during pit-stops. The solution became an entire battery module, hanging on the side of the car on two spears pointing out from the car. The batteries are exchanged by a specially designed trolley that is inserted under the battery module. To secure the batteries whilst driving they are also secured with a locking device that is quick and simple to unlock when it is time to exchange the batteries. The project resulted in a battery handling system that in comparison to already existing solutions reduce the burden on the mechanics and performs an exchange of batteries in less than half the time.

Electric car sharing is gradually expanding as an innovative and more sustainable mobility alternative to private cars. Though, the use of such mobility service has not yet reached the desired levels worldwide despite attracting large number of customers. For car sharing operators, thus, it is imperative to understand the users and their needs beyond the existing demographics and quantitative data in order to design more desirable and useful services that expand customer acceptance and usage rate of such alternative. This thesis is an exploratory study about users’ needs, behaviors, and experiences toward electric car sharing and the service requirements resulting from these dimensions. Using user- centered service design approach, the study focuses in obtaining qualitative insights about users through workshops with focus groups in regards to LEV-pool, a research project that intends to field test a new approach to car sharing by offering small size electric vehicles for local mobility at a large workplace. Based on three user-centered service design methods: customer journey map, personas, and stakeholder map, a visual mapping of users, their needs, behaviors, and experiences, and service requirements is developed. The findings point at different user types with distinct purposes of using car sharing, whose needs for mobility (at work) are affected by external factors such as work activities and job occupation. Their mobility behavior differs in terms of how they interact with car sharing service and is partly influenced by the service offering. In general, users show various experiences toward car sharing systems, and many relate it to technical aspects of the service. In terms of service requirements, the results highlight available vehicles at the needed time, simple and easy booking system with many features responsive to users’ needs, maintenance and cleanliness of vehicles, effective communication of service offering, and simple pricing schemes. The underlying user dimensions explored show as relevant in shaping the users’ evaluation of a service and their decision to use a certain mobility alternative. / Electric car sharing offers a more sustainable mobility alternative to private cars.

The study applies three user centered service design methods to capture and present a holistic understanding of users, their needs, behaviors, and experiences toward electric car sharing and the service requirements resulting from these dimensions. The findings suggest that users are distinct and have different needs for mobility (at work), which are shaped by the external factors such as work activities and job occupation. Their mobility behavior differs in terms of how they interact with car sharing service and is partly influenced by the service offering. In general, users have various experiences toward car sharing systems, and many relate it to technical aspects of the service. By exploring the users, the results point directly to different requirements that the service shall meet for it to enhance usage such as available vehicles at the needed time, simple and easy booking system with many features responsive to users’ needs, maintenance and cleanliness of vehicles, effective communication of service offering, and simple pricing schemes.

Ett produktutvecklingsprojekt har utförts på Högskolan i Skövde under våren 2017 i samverkan med företaget China Euro Vehicle Technology AB (CEVT). CEVT arbetar med forskning och utveckling inom bilindustrin och ägs av Geely Auto. I och med pågående trend och utveckling mot fullt elektriska personbilar ville CEVT med detta examensarbete undersöka hur volymen mellan framstolarna kunde disponeras, då handbroms och växelspak uteblir. Målet med uppdraget var att utveckla ett konceptförslag av golvkonsol till elbil för att riktas till den kinesiska marknaden utifrån företagets krav och målgruppens behov. Projektet inleddes med en förstudie vilken innefattade intervjuer med målgruppen och experter samt en marknadsundersökning. I förstudien undersöktes användaren och dess behov samt befintliga och framtida bilinteriörer. Framtagen information sammanställdes i en kravspecifikation tillsammans med baskrav från företaget. Koncept genererades utifrån kommande trender samt fastställda funktioner och utvärderades i flera steg. Koncept har utvärderats tillsammans med företaget, genom ergonomisimulering och användartest med en fullskalig prototyp. Resultatet är utformat i två nivåer med en teknologisk överdel, där laddplats för mobil finns placerad samt en interaktionsyta till instrumentpanelen och en underdel med fokus på förvaring. Resultatet innehåller uppdelade förvaringsutrymmen vilka är anpassade till målgruppens användare och deras tillhörigheter. Golvkonsolen är utformad med fokus på flexibilitet, funktionalitet och justerbarhet, då tillbehör kan förflyttas och bytas ut samt att armstöd och överdel kan justeras utefter behov. / A product development project has been carried out at University of Skövde in collaboration with China Euro Vehicle Technology AB (CEVT). CEVT works with research and development in the automotive industry and is owned by Geely Auto. With current trends towards developing full electric cars, CEVT wanted to explore how the space between the two front seats could be dispensed, with no handbrake or gearshift. The aim of the thesis was to develop a floor console for an electric car adapted to the Chinese market and the company's requirements. The project began with a pre study which included interviews with the target group and experts as well as a market research. The pre study studied user needs and different car interiors. The information was compiled in a requirement specification together with demands from the company. Concepts were generated based on future trends and identified functions and then evaluated in several steps. The concept has been evaluated with the company, through ergonomic simulation and a user test with a full-scale prototype. The result is designed in two levels, the top focuses on technology where a charging station is placed as well as an interaction area for the dashboard the base is instead focused on storage. The result contains different storage solutions customized and developed for the user and their belongings. The floor console is designed with focus on flexibility, functionality and adjustability as parts can be moved and replaced. The armrest and top can also be adjusted according to different needs.

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. After this timeframe the voltage drop becomes a serious concern and should be addressed. / Utmaningarna som lågspänningsnät står inför växer i takt med att fler bostäder övergår från fossilbaserad till elbaserad värme. Flera miljösatsningar och visioner ämnar pådriva samma förändring inom transportsektorn och eldrivna fordon anses som ett av de viktigaste verktygen för att genomföra detta. Med ytterligare potentiella påfrestningar på lågspänningsnäten från de elektriska fordonens behov ställs frågan hur utbredd den elektriska fordonsmarknaden kommer att bli och vilken påverkan den kommer ha på elnäten. I detta arbete belyses ett typiskt lågspänningsnät i södra Sverige och vilka effekter elfordonens utbredning kan tänkas ha på den. Genom datorstödda simuleringar enligt flera olika prognosscenarion finner arbetet att relativt få förändringar och förstärkningar behöver göras på det analyserade nätområdet inom ett tidsspann på ca 10 till 15 år. Efter detta tidsspann orsaker lasterna ett högt spänningsfall i det aktuella nätet som bör åtgärdas.
