Saar university develops self-sufficient electricity filling station

In the saarbruck district of burbach, a special filling station for e-cars is being built at kurze. The pilot plant, which is being built under the auspices of saarland university, will focus on two approaches: it will supply purely renewable electricity and operate completely self-sufficiently. The test plant is about the size of a stand and will be installed in a container with solar cells on the roof. "Inside is an electrochemical battery that temporarily stores solar energy and acts as a charging station with two sockets for electric vehicles", says chemist harald natter from the department of physical chemistry, who is leading the saar university research group in the project "opticharge" .

The electrochemical storage system consists of a vanadium redox battery. Such batteries are already being used to store wind and hydroelectric power. However, the application as a charging station for electric vehicles is new. Natter: "the technology behind it is highly complex." therefore, the cooperation partners have also distributed the tasks. The technical university of kaiserslautern, for example, is responsible for the charge management system. It is developing software that will control the work of the battery. Incoming weather data will also be taken into account to ensure optimal utilization of the solar energy. The entire system will be controlled by a central computer that will receive data from the charging station via a mobile phone line.
