\"Laminated-cell\"<\/a>                         Le communiqu\u00e9s de presse de Renault-Nissan, impr\u00e9gn\u00e9s de l'esprit du rus\u00e9 Carlos G., poussent parfois le bouchon un peu loin: affirmer vouloir transformer le Portugal en "EV Eco-Vall\u00e8e de l'Europe" n'est-ce pas un peu trop emphatique? Surtout pour une usine de 200 employ\u00e9s.<\/p>\n

                         Pour \u00e9viter b\u00eatement de recopier le Communiqu\u00e9 de Presse et essayer de comprendre ce que veut faire l'Alliance R-N dans ce domaine il est n\u00e9cessaire de conna\u00eetre la gamme op\u00e9ratoire de fabrication d'une batterie d'accumulateurs de type Li-Ion "laminated" polym\u00e8re. Tout commence par la production d'\u00e9l\u00e9ments (cells<\/span>) plats qui utilisent comme enveloppe ext\u00e9rieure un film m\u00e9tallis\u00e9 d'Aluminium  lamin\u00e9 avec plusieurs couches de divers polym\u00e8res et qui est thermosoud\u00e9. Cet \u00e9l\u00e9ment de base qui contient l'essentiel du know-how est produit au Japon. AESC avait pr\u00e9sent\u00e9 en 2008 un \u00e9l\u00e9ment de 13Ah, de 527g. La deuxi\u00e8me \u00e9tape consiste \u00e0 assembler plusieurs de ces \u00e9l\u00e9ments plats en modules<\/span>, on peut supposer que c'est un assemblage en parall\u00e8le destin\u00e9 \u00e0 obtenir un objet de deux kilogrammes environ et d'une cinquantaine d'Ah de capacit\u00e9. Il est probable que cette \u00e9tape sera r\u00e9alis\u00e9e dans les usines japonaises, en raison de la n\u00e9cessit\u00e9 d'utiliser des \u00e9l\u00e9ments homog\u00e8nes en capacit\u00e9s pour les assembler en modules. Enfin la derni\u00e8re \u00e9tape consiste \u00e0 assembler ces modules en batterie<\/span> constitu\u00e9e de modules connect\u00e9s en s\u00e9rie, d'un ensemble d'\u00e9lectronique de puissance et d'\u00e9quilibrage des modules, de divers syst\u00e8mes de s\u00e9curit\u00e9 \u00e9lectrique et thermique, de l'intelligence de la batterie, charg\u00e9e de mettre en m\u00e9moire l'historique du produit et de dialoguer avec l'ext\u00e9rieur, de connecteurs de puissance et de courants faibles, des organes de r\u00e9gulation thermique et enfin du coffre batterie qui assure l'int\u00e9grit\u00e9 physique du produit plac\u00e9 le plus bas possible, sous le ch\u00e2ssis du v\u00e9hicule.<\/p>\n

                     C'est probablement, \u00e0 mon avis, cette troisi\u00e8me \u00e9tape d'assemblage en batterie qui demande beaucoup de main d'oeuvre, rare et ch\u00e8re au Japon, qui sera d\u00e9localis\u00e9e vers les centres de distribution des produits. L'Alliance, \u00e0 peu de frais, peut ainsi argumenter aupr\u00e8s des diverses autorit\u00e9s politiques locales que sa technologie est cr\u00e9atrice localement de greenbusiness. Le Portugal et la Grande-Bretagne dans l'usine Nissan de Sunderland, ont \u00e9t\u00e9 \u00e0 ce jour choisis par Renault-Nissan pour assembler localement ces batteries des prochains v\u00e9hicules \u00e9lectriques.<\/p>\n
