Abstract

L'invention concerne un système d'équilibrage de batterie (10) comprenant : un bloc-batterie (11) ; des circuits d'acquisition (12) utilisés pour acquérir des informations de paramètre de cellules de batterie (111) dans le bloc-batterie ; des circuits d'équilibrage (13) utilisés pour réaliser un équilibrage sur les cellules de batterie dans le bloc-batterie, chacun des circuits d'équilibrage comprenant une première résistance (131) connectée en parallèle aux deux extrémités d'une cellule de batterie dans le bloc-batterie, et la première résistance étant une thermistance à coefficient de température positif ; et des dispositifs de commande (14), dont chacun est utilisé pour commander, lorsqu'il y a une cellule de batterie pour laquelle un équilibrage doit être démarré dans le bloc-batterie, le circuit d'équilibrage pour décharger la cellule de batterie pour laquelle un équilibrage doit être démarré. L'invention concerne également un véhicule comprenant le système d'équilibrage de batterie. Selon le système, le problème technique de performance de travail influencée d'un système d'équilibrage de batterie provoqué par l'augmentation de la température du système à cause de la chaleur générée lorsqu'une résistance d'équilibrage réalise un équilibrage est résolu.
