Tydligen ska gamla MEB bilar gå att bygga om till V2G.

From 2022 onwards, every electric car from the Volkswagen Group that is based on the MEB (“Modularer E-Antriebs-Baukasten” but “modular electrification kit” according to Google) electrical platform can not only be charged with electricity but also return it to the grid. In addition to VW, the MEB is also used by the sister brands Audi , Skoda and Seat-Cupra.
The first generation of MEB models that Volkswagen has been delivering since autumn last year is not yet designed to be bidirectional. These cars can only charge. Volkswagen will be able to retrofit V2G to those cars with comparatively few technical changes and additional software.
Production should begin in December, and the bidirectional electric cars will go on sale after the turn of the year. At least 300,000 vehicles are likely to be manufactured at the VW plant in Zwickau alone in 2022.
