For a transponder arrangement having a transponder arranged on an object, in order to achieve longer ranges than would be possible with a purely field-supplied response mode, the transponder is provided with a chargeable electrical energy store. An inductive supply of energy from a pump circuit situated on the object is used to hold the energy store in a charged state. The transponder arrangement can advantageously be interrogated not only in the active mode now made possible, but also in a passive mode which is known per se and is supplied with power purely by the interrogation field.

1. A transponder arrangement for an object having a dedicated power source to operate the object, comprising:a transponder arranged on said object and configured to communicate with an external interrogation unit, the transponder including a chargeable electrical energy store from which electrical power is drawn for the transponder at least for a transmission operating mode; a pump circuit arranged on said object and coupled to said dedicated power source used to operate said object, the pump circuit producing a charging signal used to transfer energy during a charging process via an inductive coupling to the chargeable electrical energy store of the transponder without using an external field of the interrogation unit; a pump circuit coupling coil connected to the pump circuit; a transponder coupling coil coupled to the transponder, wherein the inductive coupling used to transfer energy between the pump circuit and the chargeable electrical energy store is carried out via the pump coupling coil and the transponder coupling coil.
