Abstract

L'invention concerne une borne, comprenant : un boîtier, le boîtier comprenant un couvercle arrière (260, 560) de la borne; une batterie rechargeable (190, 250, 350, 450) placée dans un espace de logement (380, 480), dans le boîtier, pour la batterie rechargeable, la batterie rechargeable (190, 250, 350, 450) comprenant une première surface et une seconde surface, et la première surface étant proche du couvercle arrière (260, 560) de la borne; une première électrode et une seconde électrode, la première électrode et la seconde électrode étant situées sur un côté interne du couvercle arrière (260, 560) de la borne; une feuille conductrice (453) située sur la première surface de la batterie rechargeable (190, 250, 350, 450), la feuille conductrice (453) étant opposée à la première électrode et à la seconde électrode; un détecteur (691) dont une extrémité d'entrée est connectée à la première électrode et à la seconde électrode, et utilisé pour détecter un état de gonflement de la batterie rechargeable (190, 250, 350, 450); et une unité de traitement (692) connectée à une extrémité de sortie du détecteur et utilisée pour commander, sur la base de l'état de gonflement de la batterie rechargeable (190, 250, 350, 450), l'entrée d'électricité dans la batterie rechargeable. La borne peut détecter, de manière opportune, si une batterie est gonflée.
