As one of its efforts related to Denmark’s EDISON (Electric vehicles in a Distributed and Integrated market using Sustainable energy and Open Networks) project (earlier post), Siemens is developing rapid charging systems for automotive batteries, initially targeting 400V and 63 amps. The long-term goal is to achieve up to 300 kW of charging capacity—enabling a quick recharge in roughly 6 minutes.
The development engineers are also investigating how the constant switching on and off of the batteries affects the power grid; the harmonics this generates could knock the grid out of sync. Here Siemens Energy is working directly on the Risø research campus of the Technical University of Denmark, a partner in the EDISON consortium.
EDISON, the world’s first and most extensive project of its kind, will bring a pool of vehicles to power outlets and connect them to the fluctuating power of the wind. The associated technology for vehicles and the grid will be developed and prepared for use over the next two years. Practical testing will begin in 2011 on the Danish island of Bornholm in the Baltic Sea.
In addition to Siemens, the EDISON consortium includes the Technical University of Denmark (DTU) and its Risø-DTU research center, as well as Denmark’s Dong Energy and Østkraft power utilities, the Eurisco research and development center, and IBM.
