Abstarct
In order to support a 40% cut of Greenhouse Gases by 2030 expected from road transport, Battery Electric Vehicles (BEV), Fuel Cell electric Vehicles (FCV), and Hybrid Electric Vehicles (HEV) must show shorter time-to-market
compared to conventional fossil fuel-based cars. Today, automotive time-to-market is minimised through the use of the standard V-model. This approach aims to reduce the development time by a decomposition of the system design (from the system to the components) and by a progressive validation of components and their integration. Digitisation of industry led to the use of more and more simulation tools in V-model. In the development axis, structural-based software tools lead to design of components/subsystems in a more accurate way. In the validation axis, the tested component/subsystem is mixed with simulation (using functional-based software tools) of other parts in the HardwareIn-the-Loop (HiL) philosophy for better validations. Virtual and real validation can be separated and the V-model can be rearranged in a W-model.
While each development step in the W-model benefits from dedicated software at its own level, the global development becomes very complex. Many different models are used for the same component, as well as different software tools in the different tasks of the W-model. Furthermore, re-using models non-systematically increases the development time and reduces reliability. The challenge is even higher for electrified vehicles as the number of components and architectures is increased compared to thermal vehicles. Different physical domains are considered and dedicated simulation tools are used. The W-model is thus more complex to manage because of the number of subsystems and their related components. To face this complexity, advanced simulation packages, co-simulation processes and dedicated real-time hardware are under development at the system level to ensure a better global vision of the vehicle operations and performances. However, this complexity leads to a higher development time due to the high number of real components/subsystems to test. Several European H2020 projects are developing new approaches to:
- Interconnect of the various models involved in the W-model.
- Development of real-time models of the subsystems for virtual and real testing of the different parts of the system.

Biography
Alain BOUSCAYROL received Ph.D. degree in Electrical Engineering from Institut National Polytechnique de Toulouse, France, in 1995. From 1996 to 2005, he was Associate Professor at University of Lille, France, where he has been a Professor since 2005. From 1998 to 2004, he managed the Multi-machine Multi-converter Systems project of GdR-ME2MS, a national research program of CNRS (French National Centre of Scientific Research). Since 2004, he has managed the national network on Energy Management of Hybrid Electric Vehicles (MEGEVH) France. Since 2015, he has been coordinator of the CUMIM (Campus of University with Mobility based on Innovation and Neutral carbon) interdisciplinary program of University of Lille. Since 2018, he has been co-director of the international research lab eCAMPUS on sustainable mobility. He is coordinator of PANDA a European H2020 project on simulation and testing of electrified vehicles, a H2020 European project (https://project-panda.eu/).. His research interests at the L2EP (Laboratory of Electrical Engineering) include Energetic Macroscopic Representation (http://www.emrwebsite.org/) for control of electric drives, wind energy conversion systems, railway traction systems, hybrid electric vehicles and hardware-in-the-loop simulation. His collaborative works with industry on energy management for vehicles include Siemens Transportation Systems, Siemens Software PSA Peugeot Citroen, Nexter Systems, Renault, Valeo and SNCF. He was General Chair of IEEE VPPC 2010, Sept. 2010, Lille, France, co-chair of EPE 2013 ECCE Europe (European Power Electronics and drives), Sept. 2013, Lille, France and co-chair of IEEE VPPC 2014, Oct. 2014, Coimbra, Portugal. In January 2014, he has been nominated Chair of the Vehicle Power Propulsion technical committee by IEEE Vehicular Technology Society. From 2014 to 2018, he had been Associate Editor of IEEE transactions on Vehicular Technology. Since 2016, has been elected Distinguished Lecturer by IEEE VTS.
