Use Case
Affordable And Clean Energy
Industry, Innovation And Infrastructure
The goal of the Use Case was to see the installation of grid-friendly and affordable charging infrastructure in the residential area. It was hoped that charging opportunities at the parking spaces of the apartment building could be realised, whilst using the existing grid connection. All these aims were hoped to be carried out, as well as through the use of a user friendly operating system with app authentication and billing of each end user separately according to the charged kWh used.
In spring 2021, MAHLE presented the charging solution for “chargeBIG” electric vehicles to four construction cooperatives, including the contract partner. Subsequently, three building cooperatives, among them the contracting partner, decided as the owner of the underground car park at the location Scharnhauserpark, Ostfildern. In a pilot project, MAHLE was commissioned to retrofit the underground car park with the chargeBIG charging solution. The installation of the chargeBIG solution with initially 17 of 36 possible charging points was completed at the beginning of 2022.
The first interested residents on site were able to rent an electrified parking space from the Building- und Homestead Association Stuttgart eG, which own the building, from March 2022. In order to be able to charge your vehicle, it is necessary to download the free chargeBIG app or to use the web app in the browser. Authentication is carried out via QR Code Scan or NFC and, if desired, the user can create a customer account. The MAHLE chargeBIG app allows mobile payment of the charging processes. Another advantage is that the chargeBIG user can also have his visit charged directly at the charging point, since the charging process is not linked to any chassis number or vehicle license plates.
