Zusammenfassung: | The present invention relates to a contactor device (100), which is capable of changing a connection state of at least two battery modules (502(1), 502(2)) of a high voltage energy storage system (10) between a series connection and a parallel connection, and to an energy storage system (10) comprising the contactor device (100). The contactor device (100) comprises two first terminals (102, 104) for electrically connecting at least one of a load and a charger, two second terminals (106, 108) for electrically connecting a first battery module (502(1)), and two third terminals (110, 112) for electrically connecting a second battery module (502(2)). The contactor device (100) further comprises two first bus bars (128, 129), which each are electrically connected to one of the first terminals (102, 104), and two second bus bars (138, 139; 238, 239), wherein one of the second bus bars (138; 238) is electrically connected to one of the second terminals (106), and the other one of the second bus bars (139; 239) is electrically connected to one of the third terminals (112), and a connection bus bar (144), which is electrically isolated from the two first bus bars(128, 129). At least one actuation element is configured to change a state of the contactor de-vice (100) at least to and from a series connection state, in which the two second bus bars (138, 139; 238, 239) are conductively coupled to the connection bus bar (144), and to and from a parallel connection state, in which one of the second bus bars (138; 238) is conductively coupled to one of the first bus bars (128) and the other one of the second bus bars (139; 239) is conductively coupled to the other one of the first bus bars (129).
La présente invention concerne un dispositif contacteur (100), qui est capable de changer un état de connexion d'au moins deux modules de batterie (502 (1), 502 (2)) d'un système de stockage d'énergie haute tension (10) entre une connexion en série et une connexion en parallèle, et un système de stockage d'énergie (10) comprenant le dispositif contacteur (100). Le dispositif contacteur (100) comprend deux premières bornes (102, 104) pour connecter électriquement une charge et/ou un chargeur, deux secondes bornes (106, 108) pour connecter électriquement un premier module de batterie (502 (1)), et deux troisièmes bornes (110, 112) pour connecter électriquement un second module de batterie (502 (2)). Le dispositif contacteur (100) comprend en outre deux premières barres omnibus (1 |
