The 4th General Assembly of i-HeCoBatt was celebrated on 3rd September 2020 online, due to the COVID19 restrictions. However, it was the right chance to compile all the work carried out by the consortium during the first period and to plan properly all together the next steps. By this mid-term milestone, i-HeCoBatt project already fulfilled some of the most critical milestones, such as the thermal characterization of the current heating and cooling system, the final model and the design of the A-Sample HE prototype and the development of the thermal management diagnostic and safety SW tool. The activities are progressing appropriately and the first relevant results were shared between the partners. The day after, the Review Meeting was celebrated online and the consortium had the chance to share with the European Commission’s project officer the progress done during the first half of the project.
