Summary:A rechargeable battery arrangement includes a plurality of rechargeable battery cells which are connected in series and each have a first and a second connection, and a plurality of differential amplifiers each having an inverting input, a non-inverting input and an output at which an amplified difference between the signal at the inverting input and the signal at the non-inverting input is produced. The non-inverting input of one of the plurality of differential amplifiers is coupled to the second connection of a first rechargeable battery cell unit of the plurality of rechargeable battery cells and to the first connection of a second rechargeable battery cell unit of the plurality of rechargeable battery cells. The inverting input of the one of the plurality of differential amplifiers is connected to the first connection of the first rechargeable battery cell unit of the plurality of rechargeable battery cells via a first resistor and to the second connection of the rechargeable battery cell unit of the plurality of rechargeable battery cells via a second resistor. The output of the differential amplifier is connected to the second connection of the second rechargeable battery cell unit.
