For instance, we have developed a VR serious game in which the user drives an electric car with a chosen type of battery and has to collect three gifts placed on a virtual map. While driving the car, the user sees a 3D microstructure of the battery cell cathode that evolves as the car is used. As the car accelerates, the virtual battery cell discharges faster and the available charge decreases . We have already reported the technical details and case studies about these serious games and others in previous publications (Figure ) - . We have also generated and analyzed a VR digital twin of our battery manufacturing pilot line, Simubat 4.0 Gen-1, also usable from the web .
