Device and method for dynamically adjusting an operating voltage for an electric motor (), which voltage is provided by a voltage source () formed in a modular manner, wherein modules (-) of the voltage source () formed in a modular manner are switched in dependence upon a rotational speed (n) of the electric motor () such that the overall degree of efficiency of the electric drive train is improved in a low rotational speed range of the electric motor (), wherein the modules (-) of the voltage source () are switched by means of a switching network () which is composed of controllable power switches () and can be actuated by control signals which are generated by a switching controller () in dependence upon the rotational speed (n) of the electric motor ().

Method and device for dynamically adjusting an operational voltage for an electric motor

Device for contacting electrical energy storage cells of an energy store, which are each connected at their poles to a printed circuit board via an electrically and thermally conductive contact element, said printed circuit board being provided to separate an electrical current, received by the respective energy storage cell via the contact element, from a heat flow received via the contact element.

Energy storage device

Disclosed is a micro-electro-mechanical switch, including a substrate having a gate connection, a source connection, a drain connection and a switch structure, coupled to the substrate. The switch structure includes a beam member, an anchor and a hinge. The beam member having a length sufficient to overhang both the gate connection and the drain connection. The anchor coupling the switch structure to the substrate, the anchor having a width. The hinge coupling the beam member to the anchor at a respective position along the anchor's length, the hinge to flex in response to a charge differential established between the gate and the beam member. The switch structure having gaps between the substrate and the anchor in regions proximate to the hinges.
