The safe, convenient and efficient charging and discharging of electric vehicles is essential for the breakthrough of electromobility. High demands are placed on the interface between the charging point and the electric vehicle. The charge point must also meet high standards when feeding power back into the grid to guarantee grid quality and stability. For the optimisation and further development of these crucial factors, extensive tests with network emulation and vehicle emulation are indispensable.

These are therefore the two most important elements in testing charging stations. The grid emulation simulates the grid with all possible fluctuations and contaminations. An adjustable load in combination with a vehicle communication simulator simulates the characteristics of the electric vehicle and battery.

An overview of the various test set-ups for the different charging modes can be found in this application note.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
