Method for providing energy and energy supply unit

摘要

The method involves designing and handling or operating a power supply unit in a container that is in a form of a galley-trolley (1) or luggage or cargo container in a commercial aircraft. The power supply unit is attached to a local consumer network over docking interfaces (8). The docking interfaces are laid out for supplying heating and/or cooling units and lighting units in an on board kitchen and/or in the cargo. An independent claim is also included for a power supply unit comprising a container.
