La technologie d\u2019hybridation commun\u00e9ment appel\u00e9e \u00ab l\u00e9g\u00e8re 48 volts \u00bb est en train de s\u2019imposer un peu partout. Focus sur une solution pr\u00e9sent\u00e9e comme peu on\u00e9reuse, facile \u00e0 implanter et qui permet de faire baisser la consommation comme les \u00e9missions de CO2.<\/p>\n

Le march\u00e9 \u00e9lectrique reste marginal tandis que les v\u00e9hicules hybrides ou hybrides rechargeables peinent \u00e0 s\u2019imposer. Pourtant, les constructeurs sont dans l\u2019obligation de faire la chasse aux \u00e9missions de CO2 afin de r\u00e9pondre \u00e0 la norme europ\u00e9enne de 2020 imposant que chaque v\u00e9hicule particulier neuf devra \u00e9mettre, au pire, 95 g\/km de CO2 (et 75 g\/km en 2025 !). Et cette fois-ci sans tricher ! La norme actuelle (de 2015) permet 130 g\/km. Au-del\u00e0, il y a p\u00e9nalit\u00e9 financi\u00e8re. Et si l\u2019on peut discuter de la pertinence d\u2019une telle mesure, le fait est que les constructeurs doivent agir. Pour cela, ils peuvent compter sur les \u00e9quipementiers, d\u00e9sormais bien plus que de simples sous-traitants. Qu\u2019il s\u2019agisse de Bosch, Continental, Continental, Faurecia ou Valeo\u2026 Tous proposent une technologie baptis\u00e9e mild hybrid<\/em> ou hybride l\u00e9ger.<\/p>\n

Des consommations en baisse de 10 \u00e0 15% ?<\/h2>\n

Tout l\u2019int\u00e9r\u00eat de ce syst\u00e8me r\u00e9side dans le fait qu\u2019il s\u2019associe \u00e0 une motorisation essence (3 cylindres la plupart du temps) sous l\u2019aspect d\u2019une batterie 48 volts. S\u2019il n\u2019y a rien de fondamentalement original, cela n\u2019a rien \u00e0 voir avec la batterie 12v qui alimente les optiques et le multim\u00e9dia. Cette batterie permet de contribuer pour environ 20 chevaux \u00e0 l\u2019effort de traction, soulageant ainsi d\u2019autant la m\u00e9canique thermique (et donc la consommation). C\u2019est certes moins efficace qu\u2019une batterie \u00e9lectrique de voiture hybride (de 300 volts) mais cela permettrait de faire baisser la conso d\u2019essence de l\u2019ordre de 10 \u00e0 15%, surtout lors d\u2019un usage citadin. Contrairement \u00e0 une hybridation lourde (par opposition), l\u2019hybridation l\u00e9g\u00e8re 48v ne serait pas si on\u00e9reuse que cela. Autour des 1 000 euros. Un chiffre qui permet ainsi de penser qu\u2019une voiture essence qui en serait \u00e9quip\u00e9e resterait plus abordable que sa version diesel.<\/p>\n

De la prochaine Clio au SQ7<\/h2>\n

Il semble alors \u00e9vident que la technologie mild hybrid ouvrira l\u2019hybride \u00e0 tous. D\u2019apr\u00e8s Michel Forissier, directeur R&D de la division moteur de Valeo et cit\u00e9 par Le Monde<\/a>, \u00ab l\u2019hybride l\u00e9ger va cr\u00e9er un effet de masse qui va contribuer \u00e0 diviser par son co\u00fbt par deux d\u2019ici deux \u00e0 trois ans. Vers 2025, il devrait repr\u00e9senter 10% du march\u00e9 mondial, soit 10 \u00e0 12 millions de v\u00e9hicules par an <\/em>\u00bb. Car oui, l\u2019ensemble des constructeurs s\u2019y mettent. De Renault \u00e0 Volkswagen en passant par BMW et Honda. A titre de comparaison, le pionnier de la voiture hybride grand public, Toyota, vient de f\u00eater ses 1,50 million de voitures hybrides alors que la Prius a d\u00e9marr\u00e9 sa carri\u00e8re en 1997. Si bien que la prochaine g\u00e9n\u00e9ration de Renault Clio devrait en b\u00e9n\u00e9ficier tandis que le spectaculaire Audi SQ7<\/a> en est d\u00e9j\u00e0 \u00e9quip\u00e9 mais cette fois-ci dans un r\u00f4le d\u2019alimentation du turbocompresseur \u00e9lectrique. Ainsi que la technologie mil hybrid <\/em>ne semble usurper sa r\u00e9putation naissante d\u2019hybridation pour tous. Surtout, cette 48 volts arrive au bon moment pour accompagner la progression des parts de march\u00e9 des motorisations essence en Europe au d\u00e9triment du diesel. <\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
