A circuit arrangement for electrically driven motor vehicles with an electric driving motor which is fed from a driving battery, with a transformer which is adapted to be connected on the primary side to an A.C. power supply network and on the secondary side by way of a rectifier arrangement to the driving battery, and with a D.C. converter which includes a chopper, an A.C. voltage step-down device and a rectifier and which recharges a power supply battery having a rated voltage that is lower than that of the driving battery, from the driving battery; the transformer thereby forms the A.C. step-down device, to one side of which the driving battery is connected by way of the chopper and to the other side of which the power supply battery having a correspondingly matched stepped-down ratio is connected by way of the rectifier.
