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.
On the one hand, the thermal characterisation of the battery pack was presented by CEA, showing the most relevant results obtained at their testbench. The officer had the chance to see the detailed thermal behaviour of AUDI’s battery pack, characterised in a climatic chamber while being operated according to the extreme operating conditions that could be observed in the car. CEA and CIDETEC Energy Storage also explained how they modelled the battery pack by using that experimental data.
On the other hand, MIBA presented their novel heating and cooling concept, showing among others the innovative flow field approach and the design and manufacturing process of the first prototype. Besides, CIDETEC Energy Storage reported the modelling and simulation activity done in close collaboration with MIBA, which facilitated the decision making process during the design phase. Once the prototype is finished, it will be assembled to AUDI’s battery pack, in order to launch the second test-bench and on-track test campaign.
DATIK had the chance to present their diagnostics and safety SW tool, whose first version is already implemented in an external device and has access to a cloud-based platform where all the valuable data monitored by the innovative heat exchanger will be stored. VERTECH shared the first results of the environmental and economic assessments that they are carrying out to the proposed solutions, as well as the first market research and dissemination and communication activities
At the end of the assembly, the partners agreed the scheduling of the works for the 2nd period, where, among other works, the innovative solutions will be tested and validated in CEA’s test-bench and AUDI’s vehicles on the tracks.
