Abstract

La présente invention concerne un véhicule électrique et un procédé d'alimentation électrique pour un véhicule électrique. Selon le véhicule électrique : un premier bloc-batterie est raccordé à un chargeur monté sur véhicule (3) ; une rainure de montage (1) est formée sur un cadre de véhicule (5) sous un plancher de coffre (4) d'un coffre du véhicule électrique ; et un second bloc-batterie (2) est disposé de manière amovible dans la rainure de montage (1), le second bloc-batterie (2) comprenant au moins : un boîtier de bloc-batterie (21) qui est raccordé de façon détachable à la rainure de montage (1) ; une plaque à bornes (22) est raccordée à une partie inférieure du boîtier de bloc-batterie (21) ; une cellule de batterie (23) est raccordée à la plaque à bornes (22) ; une première extrémité de deux faisceaux de câbles haute tension (24) est raccordée au chargeur monté sur véhicule (3), et une seconde extrémité de ceux-ci traverse la rainure de montage (1) et le boîtier de bloc-batterie (21) pour se raccorder électriquement à la plaque à bornes (22) ; le chargeur monté sur véhicule (3) surveille en temps réel la puissance requise d'un moteur monté sur un véhicule et la puissance de sortie du premier bloc-batterie et du second bloc-batterie (2), et sélectionne au moins l'un parmi le premier bloc-batterie et le second bloc-batterie (2) pour fournir de l'énergie au moteur monté sur véhicule. La présente solution non seulement augmente l'autonomie mais réduit également la difficulté de remplacement de batterie au moyen d'un moyen de remplacement local. Il n'est donc pas nécessaire de passer à des stations d'échange de batteries, ce qui offre un gain de temps considérable à l'utilisateur.
