From the beginning of the project to the end of the period covered by the report, the work performed can be distinguished per work package:
In WP1 (CRF), the specification and requirements of the SELFIE system applied in the Doblo BEV, through the definition of electrical, thermal, dimensional and gravimetric parameters as well as representatives use-case scenarios applied during validation testing were defined. In D1.2 on cell choice for the module, looking with critical eye the different cell arrangement proposed for the SELFIE was also provided. In D1.3 Concept and Test plan to be executed on the SELFIE system was described considering functional verification, lab characterization and final verification.
In WP2 (LBF), with reference to WP1 and the battery selection, the first draft of the SELFIE battery system was proposed.The design and simulation of each component comprising the SELFIE battery system and the thermal management unit are detailed in D2.1 which was used for assessment of the overall performances of the SELFIE pack at the system level. The achievement of design freeze of the detailed CAD of the battery pack enabled to begin the manufacturing of the housing of the the battery pack.
In WP3 (VCC), the simulation platform derived from the GHOST project was successfully developed and used at the end of the project to simulate complete thermal management system. Mock-up tests were conducted and efforts were made to enhance the heat transfer performance of PCM integrated in aluminium foil in CSD by doubling the heat transfer area. Numerical investigations were conducted to rectify the drawbacks and to derive a stable operating refrigeration system. The vehicle integration of thermal system and control system development on bench test were conducted during the last project period.
In WP4 (IMECAR), worked on the CAD design adjustments regarding cradle and battery pack regarding the assembly process. Spacer materials between cells for swelling tolerance, electrical isolation and thermal pad to be used along with the rest of bill of materials (BOM) have been determined. Functional and safety verification tests of the battery system were carried at IMECAR and once the demo EV was found suitable for higher TRL testing, it was delivered to CRF for further evaluations and final assessments.
In WP5 (ViF), the Hazard Analysis and risk assessment (HARA) of the system was done. In Task 5.1 (ST5.1.1) a process model concerning functional safety was created with the tool EPF-Composer based on ISO 26262 the automotive standard for functional safety. A Methodology for multi-concern assurance along with functional safety concept for the battery system (T5.1) is available. In Task 5.2 the experimental setup is performed for evaluating thermal and electrical performance of battery module at lab level.
In WP6 (CRF), the complete characterization of a baseline vehicle - Nissan eNV200, was identified, instrumented and tested in a climatic chamber with rolling bench. The details are available in the technical report (Part B). The demo vehicle was successfully integrated and received at CRF, where performance evaluations were performed. It is seen that the objectives of SELFIE are met with respect to novel thermal management, cabin thermal control, vehicle thermal control during fast charging and for a long distance drive as indicated in WP1.
In WP7 (I2M), the official project website was launched and represents the principal means of disseminating and exploiting the project results. The first version of Dissemination Plan sets the overall dissemination policy to be followed (D7.2). The project flyer was updated.The four newsletter have been published to reach wide audience and non-subscribers. In total, 13 open access publications were achieved. The project was disseminated at 16 conferences.
