    Sammanfattning : With the rising number of electric vehicles in the Swedish vehicle fleet in combination with the rising electricity demand in the country, it begs the question. How should the electricity demand from charging of electric vehicles for vital societal functions be managed in a time of crisis without the support from the electric grid? This study focuses on the task of dimensioning reserve power systems for electric vehicle (EV) charging of parking spaces with 10, 20 and 30 cars. LÄS MER
