Abstract

L’invention se rapporte à un Véhicule (10) comprenant un plancher et une batterie électrique (4) placée sous ledit plancher, ledit véhicule comprenant en outre une couche de mousse (17) d’absorption acoustique insérée entre le plancher (2) et ladite batterie (4) de sorte que ladite couche (7, 17) présente une surface supérieure (18) qui est en contact avec le plancher et une surface inférieure qui est en contact avec ladite batterie (4). Selon l’invention, au moins l’une desdites deux surfaces (18) forme au moins un joint (20, 30) destiné à augmenter l’absorption acoustique de la mousse (17) insérée entre le plancher et la batterie (4).
