With Simubat 4.0 Gen-1 it was possible to explore our battery pilot line using VR allowing users to immerse themselves in a battery production line and virtually manufacture a cell by going through all manufacturing steps in succession. At each step, the user has to choose the right input parameters so that the electrochemical properties of the battery cell matched the objectives set at the first step . Simubat 4.0 Gen-2 uses the virtual environment from Gen 1 and adds an innovative MR functionality (Figure ). Simubat 4.0 Gen-2 (Figure ) responds to a strong need arising from the construction of several battery Gigafactories, particularly in the Hauts de France region, home of our Université de Picardie Jules Verne. .
