Abstract: Vehicles and methods for cooling a cabin using a cold roof of the vehicle are provided. The vehicle includes a roof, a cabin, and an insulation layer disposed between the roof and the cabin. The vehicle also includes a passage that fluidly couples the roof with the cabin. The passage is switchable between an open mode and a closed mode. The passage is switched between the open mode and the closed mode depending on a relationship between a roof temperature, a cabin temperature, and/or a threshold temperature. The passage may be formed through the insulation layer or extend outside of the insulation layer fluidly coupling the roof with the cabin.

Abstract: A method operates an electric energy storage that is provided for an electric consumption unit, wherein the electric consumption unit is additionally coupled to an electric power grid. The method is characterized in that the control device performs the following steps of a) providing different operation logics for controlling the power flow as a function of the state of charge and of a total unit load, b) observing a status signal that is signaling the present and/or the next supply condition of the grid, c) selecting one of the operation logics as an active operation logic depending on a current value of the status signal, and d) operating the power converter according to the active operation logic.
