## Abstract

An access arrangement for a vehicle comprises a vehicle-side unlocking device for actuating an unlocking mechanism and a vehicle-side rechargeable electrical energy storage device configured to supply the unlocking device with energy. Furthermore, it comprises a vehicle-side charged electrical energy storage device configured to charge the vehicle-side rechargeable electrical energy storage device. The access arrangement further comprises a charging control device for controlling the charging process of the vehicle-side rechargeable electrical energy storage device by the vehicle-side charged electrical energy storage device. Finally, it comprises a vehicle-side authentication device for checking an access authorization and for controlling the charging control device depending on the checking of the access authorization. By providing an energy storage device which is already charged, independent of the vehicle electrical system, unlocking can be carried out quickly in the event of failure of the vehicle electrical system in an emergency running state.

## Claims

### Claim 1

An access arrangement for a vehicle, comprising:
a vehicle-side unlocking device configured to actuate a locking mechanism;
a vehicle-side rechargeable electrical energy storage device configured to supply the unlocking device with energy;
a vehicle-side charged electrical energy storage device configured to charge the vehicle-side rechargeable electrical energy storage device;
a charging control device configured to control a charging process of the vehicle-side rechargeable electrical energy storage device by the vehicle-side charged electrical energy storage device;
a vehicle-side authentication device configured to check an access authorization and control the charging control device depending on the checking of the access authorization.

### Claim 2 (depends on 1)

The access arrangement as claimed in claim 1, wherein the vehicle-side charged electrical energy storage device comprises a galvanic cell.

### Claim 3 (depends on 1)

The access arrangement as claimed in claim 1, wherein the vehicle-side rechargeable electrical energy storage device comprises a rechargeable battery or a capacitor.

### Claim 4 (depends on 1)
