Netze BW has now also completed its electromobility project in Wangen. As part of the "NETZlabor Intelligent Home Charging", eight Wangen households had an e-car exclusively for six months, which Netze BW provided to them for the duration of a project. Now the project results have been presented.
With the project, which started in November 2021, the grid operator wanted to find out what challenges a local power grid would face as a result of the ramp-up of e-mobility. For this reason, smart metering systems - i.e. digital electricity meters - were equipped with additional control boxes for the project in order to be able to temporarily control charging processes.
One of the important findings from the trial presented by project manager Sven Zahorka: In the six months of the project, a maximum simultaneity of 50 percent was recorded in Wangen - i.e. a maximum of four of the eight cars were charging at the same time. And that was at the peak; on average, the utilization rate was lower. According to Netze BW, this is in line with the results of most other trials, such as the "E-Mobility-Allee" in Ostfildern-Ruit or the "E-Mobility-Carré" in Tamm near Ludwigsburg.
The average charging time of just over three hours is probably mainly related to the vehicles used: the BMW i3 and VW e-Golf are charged in just over three hours with the 11-kW wallboxes. Only the Tesla Model 3 vehicles used had larger batteries with correspondingly longer AC charging times. On average, the vehicles were driven 1,415 kilometres per month.
