The invention relates to an attenuation circuit for an energy storage device having one or more energy storage modules which are connected in series in one or more energy supply lines and have at least one energy storage cell and a coupling device which has a multiplicity of coupling elements and is designed to selectively switch or bridge the energy storage cell in the respective energy supply line. The attenuation circuit comprises a current detection device which is designed to detect an output current of the energy supply lines or of the energy storage device and to generate an output current signal dependent on the output current, a control circuit which is coupled to the current detection device and is designed to control the output current signal to a desired current signal and to output a corresponding current control signal, and a pulse width modulation device which is coupled to the control circuit and is designed to control the coupling device of at least one of the energy storage modules in a clocked manner on the basis of the current control signal.
