Abstract

The invention relates to an energy storage module for an energy storage device, comprising an energy storage cell module which has a storage cell series circuit of at least two energy storage cells, comprising a coupling device, which comprises a plurality of coupling elements and is designed to selectively connect the energy storage cell module into an energy supply line of the energy storage device or to bypass the energy storage cell module in an energy supply line, and comprising a driver module which is designed to generate drive signals for the plurality of coupling elements. The driver module has a first energy supply connection and a second energy supply connection. The first energy supply connection is connected to a first end connection of the energy storage cell module via a first supply line and to a first node point between two energy storage cells of the storage cell series circuit via a second supply line. The second energy supply connection is connected to a second end connection of the energy storage cell module via a third supply line and to a second node point between two energy storage cells of the storage cell series circuit via a fourth supply line. The second…
