Large scale electrification of transportation is about to start in Finland in the following decades. Electrification of the traffic is likely to cause increased electricity demand, thus also novel charging methods need to be developed. The electric grids are facing changes in demand structure. Development of the distribution grids is a long-term process, thus what comes to planning of the distribution grids the decisions needs be made proactively. Distribution business is capita intensive in nature and component lifetimes are measured in decades.

The main contribution of the research is to define the main properties of the EV charging load that are relevant in the planning process. Secondly, the purpose is to develop methodology for analysing charging behaviour and estimating the grid effects and challenges posed to planning activities. Thirdly calculation and analysis methodology is tested on an actual distribution grid data in order to validate and demonstrate developed methodology.
