## Abstract

In a camper having a battery and electric comfort functions, the battery has a great capacity for supplying electricity to a travel drive of a towing vehicle, and/or is designed for an optional travel drive of the camper during trailer operation in road traffic, and the electric comfort functions are supplied with electricity from the battery.

## Claims

### Claim 1

A camper comprising a camper travel drive, a rechargeable battery, electric comfort functions, further electricity consumers, and a controller, wherein:
the rechargeable battery has a capacity of greater than 50 kWh for supplying electricity to a towing vehicle travel drive and the camper travel drive during trailer operation in road traffic;
the rechargeable battery supplies electricity to the electric comfort functions through a voltage transformer and to the further electricity consumers;
the controller enables autarchic operation of the electric comfort functions under power supplied by the rechargeable battery;
the electric comfort functions and the further electricity consumers are divided into different electrical circuits; and
the controller prioritizes certain of the electric comfort functions by turning on, turning off, or reducing power to the different electrical circuits to extend an autarchic operation period of the electric comfort functions.

### Claim 2 (depends on 1)

The camper according to claim 1, wherein:
the rechargeable battery is arranged below a floor of the camper, as an under-floor battery.

### Claim 3 (depends on 2)

The camper according to claim 2, wherein:
the rechargeable battery divided into a front battery and a rear battery between which an axle is arranged.

### Claim 4 (depends on 3)

The camper according to claim 3, wherein:
the electric comfort functions comprise at least one or more of the following: air conditioner, electric heater, electric hotplates, electric oven, electric hot-water heater, ventilation, TV/radio systems, electric outdoor grill, air compressors for pneumatic suspension, water pumps, and maneuvering drive for the camper.

### Claim 5 (depends on 2)

The camper according to claim 2, wherein:
the electric comfort functions comprise at least one or more of the following: air conditioner, electric heater, electric hotplates, electric oven, electric hot-water heater, ventilation, TV/radio systems, electric outdoor grill, air compressors for pneumatic suspension, water pumps, and maneuvering drive for the camper.

### Claim 6 (depends on 1)

The camper according to claim 1, wherein:
the electric comfort functions comprise at least one or more of the following: air conditioner, electric heater, electric hotplates, electric oven, electric hot-water heater, ventilation, TV/radio systems, electric outdoor grill, air compressors for pneumatic suspension, water pumps, and maneuvering drive for the camper.

### Claim 7 (depends on 6)

The camper according to claim 6, wherein:
the electric heater is an electric space heater.

### Claim 8 (depends on 1)

The camper according to claim 1, wherein:
the rechargeable battery can be charged from a public power grid, by way of a charger.

### Claim 9 (depends on 8)

The camper according to claim 8, wherein:
power consumption of the charger can be restricted.

### Claim 10 (depends on 1)

The camper according to claim 1, wherein:
the voltage transformer comprises 230 V alternating current.

### Claim 11 (depends on 1)

The camper according to claim 1, wherein:
the rechargeable battery is a lithium ion battery.
