The chair "Production Engineering of E-Mobility Components" (PEM) of RWTH Aachen University is dedicated to the development of an automatic battery charging robot for electric vehicles together with numerous partners in the research project "GINI". The aim is to create a semi-autonomous mobile assistant with fast-charging technology and an inductive charging interface.

E-filling station and data recorder

In addition to functioning as an e-filling station for electric cars in urban areas, the robot will also be able to charge e-bike sharing stations as well as record, pre-process and analyze data in a networked environment. In this way, "GINI" is expected to make a significant contribution to the urgently needed expansion of cost-efficient, high-performance and flexible charging infrastructure for e-mobility. The project is expected to produce two charging robots and e-bike sharing stations that will demonstrate the capabilities of a smart charging infrastructure and allow more grid-oriented charging.

Inductive charging system

With project partner INTIS, PEM is developing a bidirectional system in the rear area of the robot, the counterpart of which will be housed in a "table" under which GINI parks in reverse. Thus, the robot can charge the station, which is equipped with stationary memories, and the station in turn can charge the robot. The primary and secondary sides of the inductive system are installed in both the robot and the station.

Official approval to demonstrate feasibility

In the end, the developed test vehicles are to be officially approved to demonstrate their feasibility for small-scale production and the market. Prior to this, findings are to be incorporated into the development through extensive tests under conditions close to the application. The continuous environmental data acquisition is to be used beyond the scope of the project. The PEM chair is responsible for developing the concept for the automated mobile charging robot. The knowledge gained in this process is to be used for the construction of the primotype and prototype.
