Contactor for an electric vehicle, with at least one fixed contact element and a movable contact element which, in a disconnection position, is spaced from the at least one fixed contact element in order to interrupt an electrical connection of the two contact elements, and which, in a closed position, is in electrically conductive contact with the at least one fixed contact element in order to create an electrical connection of the two contact elements, and with a switch actuator, associated with the movable contact element, which is designed to move the movable contact element into the disconnection position or into the closed position.

Contactor for an electric vehicle

The invention relates to the redundant supply of kinetic energy to a drive system of an aircraft in order to ensure in each case largely safe operation of the aircraft during normal operation of the system and also in various emergency scenarios. The system has two electrical machines (), each of which is connected to in each case one of the two propellers. A high-voltage battery () and an internal combustion engine () are also provided. These components of the system are, depending on the type of component, electrically and/or mechanically connected to one another and to the propellers, and a controller of the system controls energy flows between the components depending on the mode of operation or readiness for operation of the components in a redundant manner in such a way that the aircraft can be largely safely operated in various normal and emergency situations.

System for redundant supply of kinetic energy to drive system of aircraft

A charging device for securing a charging process of a high-voltage battery of a motor vehicle, which may be provided with a first connecting device for coupling a charging cable of a charging station external to a vehicle and a second connecting device for connecting the high-voltage battery. A diode element may be provided between the first connecting device and the second connecting device, which may be adapted to independently allow a charging current to flow from the charging stations into the battery and prevent a discharge current from flowing from the high-voltage battery to the charging station. The charging device may further include a monitoring device configured to detect a predetermined feedback situation, in which the diode element blocks the discharge current or prevents the discharge current from flowing through the diode element during a defect. When a feedback situation is detected, a predetermined emergency shutoff measure is taken.

Charging device and charging method for a high voltage battery of a motor vehicle

A printed circuit board includes a high voltage section, a high current conductor which is arranged in the high voltage section, and a low voltage section which is separated from the high voltage section. For this purpose, the low voltage section has shielding layers which shield the low voltage section from the high voltage section. A signal processing device is embedded between the shielding layers.

A method for cleaning electrical contacts of an electrical switching device includes displacing a first electrical contact element and a second electrical contact element of an electrical contact relative to each other so that the first electrical contact element and the second electrical contact element are in a closed position; and when the first and second electrical contact elements are in the closed position applying a waveform on the electrical contact so that the first contact element and the second contact element are excited to undergo a mechanical vibration relative to each other.
