Abstract
Sweden’s road traffic is responsible for a great part of the emissions of greenhouse gases in the country. Conventional vehicles, driven by fossil fuels, have low efficiency and emits environmentally destructive particles. Electric vehicles can be the solution! Electric vehicles have no local emissions while driving and the electric motors of today have an efficiency of above 90 %. But there are some disadvantages.
This master’s thesis investigates the electric car market in Sweden and the different charging techniques that exists today. An examination of where Malmö stands regarding a future transition towards electric road traffic is also made. Electric roads are a possible charging technique for the future. An electric road is...

Sweden’s road traffic is responsible for a great part of the emissions of greenhouse gases in the country. Conventional vehicles, driven by fossil fuels, have low efficiency and emits environmentally destructive particles. Electric vehicles can be the solution! Electric vehicles have no local emissions while driving and the electric motors of today have an efficiency of above 90 %. But there are some disadvantages.
This master’s thesis investigates the electric car market in Sweden and the different charging techniques that exists today. An examination of where Malmö stands regarding a future transition towards electric road traffic is also made. Electric roads are a possible charging technique for the future. An electric road is modelled between Malmö and Lund, this constitutes case study 1. Dimensions and cost analysis of the distribution grid for the electric road is performed. Case study 2 and 3 examines the impact on substations, in form of transformer load, due to a growing electric car fleet.
The electric road study shows that the total investment cost for a distribution grid is relatively low and the combined energy consumption from the traffic is manageable. The result from case study 2, which looks at uncontrolled static charging in households, shows that overload in substations can occur in areas with high shares of electric heating systems. Case study 3 investigates static charging at workplaces. The result from this study shows that a high and concentrated load can occur in substations, due to fixed working hours.
The conclusions from this master’s thesis are that the electric car market is very good and that static charging dominates today. Electric roads have a great potential, the electric cars can go down in battery size and time can be saved due to charging while driving. To decrease the load in substations, from static charging, companies have to invest in intelligent measurement and control systems. (Less)
Popular Abstract (Swedish)
Elbilars utveckling går fort framåt och fler väljer att investera i en. Vilka olika laddningstekniker finns det? Hur kommer laddningen av elbilar påverka våra elnät? Kraftdistribution till en elvägssträcka modelleras för att påvisa kapacitetskrav och kostnader. Studien visar även hur hemmaladdning och arbetsplatsladdning kan påverka belastningen i elnätet om reglering uteblir.
