Wulf Schlachter, C-Level Consultant, DXBeClosing Panel — State of the Industry
Moderator: Wulf Schlachter, C-Level Consultant, DXBe | Panelists: T.B.C.The event was created in collaboration with Pionix and Eveyo to work together on the future of EV Charging. With EVerest, we’ve embraced the open-source mindset. But in the industry and among major brands, this kind of exchange is often lacking. That’s why we wanted to create a place where code and experience – not products – are shared.
