This papers investigates the impact of electric vehicle charging on residential low-voltage networks. The analysis is based on real life data of both driving patterns and a large number of electricity networks. The focus is on comparing uncontrolled an controlled charging scenarios. The results indicate that a significant number of LV-transformers will be overloaded if no charge control is applied. Moreover, a substantial portion of LV-feeder cables will be overloaded in the case of uncontrolled charging, although much less cables are overloaded than transformers. Controlled charging of EVs can reduce the number of overloaded tranformers and cables with approximately 25 % and 8% compared to the base case scenario of 1% growth of household electricity consumption.
