Abstract
A circuit for protecting energy storage cells in which at least one energy storage cell is part of an AC battery having at least one module. The at least one module includes at least one half-bridge having two power semiconductor switches, a module storage element and a module controller. The at least one module is connected to the at least one energy storage cell to form a first connection and the first connection between the at least one module and the at least one energy storage cell has a first fuse that can interrupt the first connection. The circuit has a second connection between the module controller of the at least one module and the at least one energy storage cell.
