The growth of electric vehicles (EVs) market is an important step towards achieving carbon-free urban mobility. The coupling with renewable energy production according to an optimised model of energy management within an urban microgrid responds to tomorrow's challenges of networks and smart cities. This study aims to define an intelligent infrastructure dedicated to the recharge of EVs (IIREVs) in an urban area as a charging station empowered by photovoltaic (PV)-based microgrid. This system can facilitate interactions between the IIREVs, the public power distribution network, the users of EVs, and the surrounding building. The study provides key elements to encourage the stakeholders to develop IIREVs within societal expectations, urban planning, and in adequacy with the sustainable development goals. In addition, the study highlights multidisciplinary research position that demonstrates the need of a systemic approach to remain centred on users demand and needs, to asses efficiency at various scales of IIREVs, associated services, and power grid. By using a multidisciplinary framework leading to a technical-economic-environmental evaluation methodology for IIREVs and presenting a study case, the main result of this study focuses on requirements and feasibility of IIREVs implantation within the best fitting urban areas.

RÉSUMÉ Au cours de la seconde moitié du Pleistocene moyen se sont développés, dans l'ouest armoricain, deux groupes distincts appartenant au Paléolithique inférieur, dont les rapports sont encore mal connus : un acheu- léen assez classique et le Colomba- nien à caractères archaïques. Le Co- lombanien est caractérisé par un « outillage lourd » composé principalement de choppers, associé à un « outillage léger » dominé par les encoches et les denticulés. Mots-clés : Pleistocene moyen, Paléolithique inférieur, Colombanien, choppers.

Technological study of bifacial tools from a Mousterian industry in the Armorican Massif; example of the site of Bois-du-Rocher (Saint-Hélen, Côtes ď Armor). Known since the 19th century in the Armorican Massif from two production sites, Le Bois-du-Rocher (Côtes-d 'Armor) and Kervouster (Finistère), Mousterian bifacial tool industries can be considered as an essential component of settlement during the Late Pleistocene. The site of Bois-du-Rocher provides a glossy sandstone industry, dated to the Middle Palaeolithic, now recognized as a Mousterian industry of bifacial tools. The principal characteristic is the bifacial treatment, with most of the industry made from flake supports. The aim of this technical choice seems to be the creation of special volumetric constructions, linked with functional reasons, to create specific functional features. The emphasis is on the link between the morphological approach of the support and functional possibilities for cutting. This bifacial phenomenon is examined from different points of view to find a suitable schema of technological interpretation. Artefacts are not considered merely from a typological aspect, but as an association of different units combining active and prehensive sections.
