The new Wallbox Design Demonstrator uses Covestro’s Makrolon® RE and Makrofol® material solutions in combination with design technologies from LEONHARD KURZ and injection molding technology from Sumitomo (SHI) Demag. The partners visualized together sustainable charging in a "vehicle-to-grid" concept. This means that the vehicle battery is used as a buffer storage unit that releases electricity to the grid to compensate for power fluctuations.
