Can a low voltage power grid support one street if allhouseholds are using an electric car? A small villagein Lower Austria was selected to test the influenceof e-cars on the power grid. 18 households got 23e-cars for their daily use. A simple control technologymonitored the voltage in the grid and slowed downthe charging process if needed. Within the six weekstryout the voltage in the grid was never in a criticalstate and each morning all cars had a full battery. Theparticipants were enthusiastic and used the electriccars for 90 percent of their everyday trips, with a totalof 53.000 km in 6 weeks.In the future, the field test will be extended. In the villageObersiebenbrunn, it will be analysed how e-mobilitycan be realised in large scale residential buildings; witha focus on charging in underground parking and e-carsharing systems. In a third village called Echsenbach,an intensification of the first field test will be repeated.Winter months will provide insights into extraordinarysituations with additional consumption of heat pumpsand electric cars.
