Abstract

L'invention concerne un système d'alimentation et un dispositif à roues électriques. Le système d'alimentation comprend un cadre (1), des roues électriques (2) et des ensembles de générateurs (3), les roues électriques (2) étant montées sur deux côtés du cadre (1) ; la largeur d'une extrémité avant du cadre (1) est supérieure à la largeur d'une extrémité arrière de celui-ci ; deux ensembles générateurs (3) sont disposés à l'extrémité avant du cadre (1), et les deux ensembles générateurs (3) sont disposés en parallèle sur un côté interne du cadre (1) ; un autre ensemble générateur (3) est également disposé sur le côté interne du cadre (1) et derrière les deux ensembles générateurs (3) ; et chaque ensemble générateur (3) est électriquement connecté aux roues électriques (2) et peut fournir de l'alimentation aux roues électriques (2). Les trois ensembles générateurs (3) à faible puissance sont utilisés pour remplacer un ensemble générateur à haute puissance, ce qui améliore l'universalité des parties des ensembles générateurs et réduit le coût d'achat des pièces, permettant ainsi également de réduire le coût de maintenance d'une berline à roues électriques. Les ensembles générateurs sont montés sur la base de la caractéristique selon laquelle le cadre est large à l'avant et étroit à l'arrière, de telle sorte que l'espace structural du cadre est complètement utilisé, le système d'alimentation peut être plus compact sans augmenter la largeur de l'ensemble du véhicule, et les performances de passage de la berline à roues électriques sont ainsi assurées.
