Bordbatterie

Bordbatterie is a German term that translates to "onboard battery" or "auxiliary battery." In the context of vehicles, it refers to a secondary battery that supplements the main starter battery. This auxiliary battery is typically used to power electrical consumers when the engine is off, preventing the main battery from being discharged. Common applications include powering refrigerators, televisions, inverters, or auxiliary heating systems in campers, caravans, and recreational vehicles.

The purpose of a Bordbatterie is to provide a reliable power source for these additional appliances without compromising the vehicle's ability to start. It allows for a more comfortable and extended use of these amenities, especially during off-grid situations. The Bordbatterie is often charged by the vehicle's alternator when the engine is running, or through external charging sources like solar panels or a campsite's electrical hookup.

There are various types of Bordbatterien available, including lead-acid batteries (AGM or Gel), and increasingly, lithium-ion batteries. Lithium-ion batteries offer advantages such as lighter weight, longer lifespan, and faster charging capabilities, although they are generally more expensive. The capacity and type of Bordbatterie chosen depend on the specific power requirements of the connected devices and the intended usage of the vehicle. Proper installation and management are crucial to ensure the longevity and effective operation of the Bordbatterie system.
