A printed circuit board arrangement with a flexible layer arrangement of at least one electrically conductive layer with a large number of conductor tracks lying next to one another and surrounded by electrically isolating layers has at least one printed circuit board firmly connected to a portion of the flexible layer arrangement and accommodating a component. The electric vehicle contains a removable battery housed in the vehicle’s undercarriage. Each recess contains a sector-shaped piece of porous material, which is brazed to surfaces of the housing parts. Because the discharge path that is associated with the data signal includes a greater amount of conductance, it can perform the discharge operation at a faster rate, even where the input logic level does not exceed the voltage of the system voltage supply. A throttle element is arranged in the catalytic converter housing, in such a manner that a first reaction chamber, which lies between the throttle element and the inlet opening, and a second reaction chamber, which lies between throttle element and exhaust catalytic converter, are formed by the throttle element. In response to the operating system causing the first hardware to enter the first reduced power state, the system management controller causes the second hardware to enter a second reduced power state corresponding to the first reduced power state.
