  • Battery system, local electrical grid and disconnector
    Patent number: 11936221
    Abstract: The invention relates to a battery system, particularly for using in a local electrical grid, comprising: at least one battery module (1); an output terminal (2) which is electrically connected to the battery module (1) and used to charge and/or discharge the battery module (1) from and/or into the local electrical grid; a disconnector (3) which is arranged between the battery module (1) and at least one pole (21, 22) of the output terminal (2) and is designed to break the electrical connection between the battery module (1) and the at least one pole (21, 22) of the output terminal (2), when open; and a first signal circuit (41) which is designed to generate the triggering of the disconnector (3) in the event of a faulty state detected by the battery module (1) in such a way as to interrupt the electrical connection between the battery module (1) and the at least one pole (21, 22) of the output terminal (2).
