Abstract

L'invention relève du domaine des dispositifs d'alimentation en énergie et concerne spécifiquement un système de stockage d'énergie domestique permettant une sortie multi-tension. Le système de stockage d'énergie domestique permettant une sortie multi-tension de la présente invention vise à résoudre le problème d'un système de stockage d'énergie domestique existant ne permettant pas d'obtenir une sortie multi-tension flexible. À cet effet, le système de stockage d'énergie domestique comprend un dispositif de commande, une pluralité de commutateurs électroniques, un bus CAN, une pluralité de modules de batterie et un onduleur. Les commutateurs électroniques connectent électriquement les modules de batterie à l'onduleur par l'intermédiaire d'un bus à courant continu. Le dispositif de commande est respectivement connecté électriquement aux modules de batterie par l'intermédiaire du bus CAN et commande la mise sous/hors tension des commutateurs électroniques, de manière à assurer la connexion en série ou parallèle des modules de batterie. Dans le système de stockage d'énergie domestique permettant une sortie multi-tension de la présente invention, à l'aide des caractéristiques, le système de stockage d'énergie domestique délivre une tension élevée au moyen de la connexion en série de modules de batterie, une faible tension au moyen de la connexion parallèle des modules de batterie, et le nombre de modules de batterie effectifs peut être déterminé de manière flexible selon une tension cible.
