Abstract

La solution de la présente invention concerne le domaine technique des batteries, et fournit principalement un circuit de formation de batterie et un appareil de formation de batterie. Le circuit de formation de batterie comprend : de multiples batteries en attente de formation, les multiples batteries étant connectées séquentiellement en série, et étant connectées à une source d'alimentation afin de former une boucle en série ; un module d'échantillonnage connecté aux multiples batteries, utilisé afin d'échantillonner un paramètre de performance et un état de fonctionnement de chacune des batteries ; et un ordinateur hôte connecté à la source d'alimentation et au module d'échantillonnage, l'ordinateur hôte commandant, en fonction du paramètre de performance, de l'état de fonctionnement, et des instructions entrées par un utilisateur, un signal de courant produit par la source d'alimentation de façon à charger ou décharger les multiples batteries. Les multiples batteries sont connectées en série afin de former une boucle conjointement avec la source d'alimentation. Seules deux lignes de transmission sont nécessaires afin d'achever un processus de formation destiné aux multiples batteries, ce qui permet de résoudre le problème selon lequel un procédé de formation classique nécessitant un nombre relativement important de lignes de transmission conduit à des coûts du câblage relativement élevés et à une perte d'énergie.
