Research on future-relevant charging technology

innolectric, together with the other cooperation partners Hofer Powertrain, Bochum University of Applied Sciences, Keysight Technologies, Sensor-Technik Wiedemann (STW) and Voltavision, has successfully completed the research project “Continuous fast charging concept for electric vehicles” (D-SEe for short). Within four and a half years of joint research work, all participants have worked to develop a fast charging station as well as a prototype vehicle suitable for reproducibility. Together, these are capable of charging the energy required to drive 400 km into the vehicle battery in just 15 minutes.

Fast charging technology in future electric vehicles

The development of new test procedures, high-end charging electronics and a new communication module – the DC Charging Controller developed by innolectric – are, in addition to a real 410 km range (WLTP: 564 km) at 88 kWh and 15 minutes charging time, relevant project results that could influence the development of electromobility to a certain extent. “I assume that this fast-charging technology will be found in passenger cars in the future,” replies Christoph Dörlemann of Keysight Technologies when asked to what extent implementation in series production is conceivable.

Project goal was exceeded

“We are pleased that in the four and a half years of the project, we were able to exceed our goals,” explained Kai André Böhm at the final presentation of the research project in late summer 2022, “because with an average discharge power of 70 kW and a discharge energy of 90.3 kWh, we achieve an overall efficiency of 92 percent.”

Informative online presentations on the research project

Those interested in the topic can register in the future for the free webinar “D-SEe research project: New charging technology enables 400 km range after 15 min charging time”. The speaker will be Prof. Dr.-Ing. Kai André Böhm, professor at Esslingen University of Applied Sciences. The dates are 2/16 from 10 to 11:30 am and 3/30 from 2 to 3:30 pm. More information will be published at www.dsee-project.com.
