Le constructeur automobile chinois Leapmotor supprime la batterie 12 volts de ses futurs v\u00e9hicules \u00e9lectriques pour s'appuyer exclusivement sur la batterie haute tension. Cette nouvelle approche s'inscrit dans le cadre d'une refonte plus large de l'architecture technique de l'entreprise, qui permettra d'agrandir l'espace int\u00e9rieur des v\u00e9hicules. <\/b><\/p>\n

Si les voitures \u00e9lectriques sont \u00e9quip\u00e9es d'une batterie haute tension destin\u00e9e \u00e0 alimenter leur(s) moteur(s) \u00e9lectrique(s), elles disposent \u00e9galement d'une batterie traditionnelle de 12 volts, tout comme les voitures \u00e0 moteur \u00e0 combustion interne. Cette petite batterie alimente le syst\u00e8me \u00e9lectrique de bord. Elle alimente notamment les serrures de porte, les feux et les essuie-glaces, ainsi que les contacts qui isolent le syst\u00e8me haute tension lorsque la voiture n'est pas utilis\u00e9e.<\/p>\n

Mais les batteries 12 V comptent \u00e9galement parmi les causes les plus fr\u00e9quentes de pannes, m\u00eame sur les v\u00e9hicules \u00e9lectriques. C'est ce que montrent les chiffres fournis par des associations de mobilit\u00e9 telles que l'ADAC en Allemagne et l'ANWB aux Pays-Bas. C'est l'une des raisons, au m\u00eame titre que la simplification et l'optimisation de l'encombrement, pour lesquelles Leapmotor souhaite que la batterie haute tension prenne le relais de la batterie 12 V.<\/p>\n

Nouvelle technologie de batterie<\/b><\/h4>\n

La suppression de la batterie 12 volts s'appliquera d'abord aux nouveaux mod\u00e8les d\u00e9voil\u00e9s en 2027. Leapmotor a fait cette annonce lors de son \u2018 Tech Day \u2019 \u00e0 Huzhou. Le constructeur automobile chinois ne supprime pas le syst\u00e8me basse tension du v\u00e9hicule, mais uniquement la batterie 12 volts elle-m\u00eame. La \u00ab grande \u00bb batterie du v\u00e9hicule reprendra alors son r\u00f4le.<\/p>\n

La batterie \u00e0 l'origine de cette prouesse technique sera la batterie \u00ab High-Low Fusion \u00bb CTC 3.0 de Leapmotor. Les cellules sont directement int\u00e9gr\u00e9es au ch\u00e2ssis (CTC) et peuvent fournir \u00e0 la fois une alimentation haute tension pour le groupe motopropulseur et une alimentation basse tension pour d'autres fonctions.<\/p>\n

La batterie de traction offrira une capacit\u00e9 \u00e0 basse tension environ 7 fois sup\u00e9rieure \u00e0 celle d'une batterie traditionnelle de 12 V. De plus, cette approche rendra la voiture plus facile \u00e0 entretenir, puisque la batterie n'aura pas besoin d'\u00eatre remplac\u00e9e pendant toute la dur\u00e9e de vie du v\u00e9hicule, contrairement aux batteries de 12 volts.<\/p>\n

Une architecture de v\u00e9hicule enti\u00e8rement nouvelle<\/b><\/h4>\n

Ce nouveau bloc-batterie s'inscrit dans le cadre d'une refonte plus large de l'architecture de Leapmotor, baptis\u00e9e \u00ab LEAP 5.0 New Mobile Space Architecture \u00bb. Il est con\u00e7u pour agrandir l'espace int\u00e9rieur en r\u00e9duisant le nombre de pi\u00e8ces utilis\u00e9es (notamment en supprimant la batterie 12 V s\u00e9par\u00e9e) et en adoptant une nouvelle disposition.<\/p>\n

La nouvelle configuration pr\u00e9voit le d\u00e9placement du moteur \u00e0 l'arri\u00e8re, une meilleure int\u00e9gration du syst\u00e8me de climatisation, une technologie \u00ab cellule-ch\u00e2ssis \u00bb permettant d'obtenir un plancher plus bas et enti\u00e8rement plat ainsi qu'une hauteur sous plafond accrue, et une suspension redessin\u00e9e. Cela devrait se traduire par un gain d'espace int\u00e9rieur de 19% par rapport aux v\u00e9hicules actuels pr\u00e9sentant des dimensions ext\u00e9rieures comparables.<\/p>\n

En route pour l'Europe ?<\/b><\/h4>\n

Stellantis d\u00e9tient une participation de 21% dans Leapmotor et de 51% dans Leapmotor International, qui d\u00e9tient les droits de production et de commercialisation des v\u00e9hicules Leapmotor hors de Chine. Cette nouvelle plateforme pourrait donc avoir un impact consid\u00e9rable en Europe \u00e9galement.<\/p>\n

La marque elle-m\u00eame nourrit de grandes ambitions en Europe, et va m\u00eame construire <\/a><\/span>le B10<\/span> en Espagne<\/span><\/a>. <\/span>En plus de cela<\/span>, Stellantis est <\/span>probablement <\/span>en utilisant <\/span>les composants du B10 <\/span>pour d\u00e9velopper un futur SUV Opel du segment C<\/a>.<\/span><\/p>\n

On ignore toutefois si les voitures europ\u00e9ennes qui seront commercialis\u00e9es \u00e0 court terme utiliseront cette nouvelle technologie. Cela semble m\u00eame peu probable, compte tenu du calendrier de leur lancement et de celui de la mise en place de cette nouvelle technologie. Mais \u00e0 long terme, cela pourrait simplifier la production et l'entretien si la technologie fonctionne comme pr\u00e9vu.<\/p>","protected":false},"excerpt":{"rendered":"
