An access arrangement for a vehicle comprises a vehicle-side unlocking device for unlocking a locking mechanism. Furthermore, it comprises a vehicle-side rechargeable electrical energy storage device which is set up to supply the unlocking device with energy independently of the on-board power supply of the vehicle. Moreover, the access arrangement has a vehicle-side energy supply device comprising a first section for receiving wirelessly transmitted energy and for converting the transmitted energy into electrical energy, and a second section for charging the vehicle-side rechargeable electrical energy storage device. In particular, the access arrangement also comprises a vehicle-side authentication device for checking access authorization, which is supplied with energy independently of the on-board power supply by means of the vehicle-side rechargeable electrical energy storage device. It is therefore no longer necessary to equip a mobile identification transmitter carried by a user with the access arrangement with a mechanical key.
