A camper is a recreational vehicle equipped and built for free travel. It has spaces for sleeping and resting. The article presents an example of a conventional 230 V electrical installation used in such vehicles and the possibilities of replacing it with an intelligent installation. An EIB/KNX bus installation was used for this purpose. Furthermore, the components of such an installation, protection measures, and methods of its integration with the vehicle’s 12 V electrical system, as well as with the external 230 V installation, were presented.More and more people are spending their leisure time actively, often moving around. An alternative to conventional travel is renting or purchasing a recreational vehicle called a camper. These vehicles are increasingly common on our roads. The interiors of campers are divided into two parts: the driver’s cab and the utility (living) area, which contains spaces adapted for resting, preparing food, and storing food. In addition, recreational vehicles have a number of additional amenities such as: a shower, toilet, running water, heating system, ventilation, air conditioning, and a gas installation.
In addition to the installations and systems mentioned above, there is an electrical installation in vehicles of this type.
It is possible to connect not only devices powered by 12 V voltage (e.g., lighting, TV, refrigerator) but also devices that require single-phase 230 V mains voltage for their normal operation (e.g., DVD, computer). Due to the specific installation location, which is a car, the use of this type of installation carries the risk of electric shock or fire. For this reason, when designing this type of installation, special attention should be paid to its functionality. (…)
