  • Publication number: 20250071886
    Abstract: A device for isolating an electronic component including a printed circuit board, an electronic component positioned on a surface of the printed circuit board, and a stiffening element positioned on the surface of the printed circuit board. The stiffening element is positioned so as to at least partially surround the electronic component. The stiffening element is positioned to isolate the electronic component from an environment.

  • Patent number: 12194872
    Abstract: The present disclosure relates to a locking device for locking a charging plug in a charging socket of an electric vehicle for charging a battery of the electric vehicle, the charging socket having a plug contour which corresponds to a plug contour of the charging plug, the locking device including a locking member configured to move to a locking position upon insertion of the charging plug into the charging receptacle and further configured to move to an unlocking position upon release of the charging plug from the charging receptacle. The locking device also includes a light guide adapted to illuminate the plug contour of the charging receptacle when the locking member is in the unlock position so as to facilitate insertion of the charging plug into the charging receptacle.

  • Publication number: 20240424937
    Abstract: A method for the voltage-level determining of a charging control-system signal for charging systems of electric vehicles, in which the charging control-system signal is a pulse-width modulated, PWM, signal with adjustable pulse width and the method includes recording measurement values of the charging control-system signal in a time range prescribed by a measurement window. The method includes recognizing a falling slope of the charging control-system signal and of a corresponding time point of the falling slope based on the charging control-system signal and a prescribed threshold value; and upon recognizing the falling slope of the charging control-system signal, determining a voltage level of the charging control-system signal based on at least one first part of the measurement values of the charging control-system signal recorded in the measurement window, which measurement values have been recorded before the time point of the falling slope of the charging control-system.

  • Publication number: 20230358615
    Abstract: The present disclosure relates to a temperature measuring device for measuring a temperature of a pin-shaped electrical contact element, which includes a flexible circuit board with a first thermally conducting and electrically insulating substrate layer. The first substrate layer includes a contact surface that is configured to lie flat against a flange of the pin-shaped electrical contact element and an opening disposed in the contact surface. The pin-shaped electrical contact element is disposed at least partially in the opening. The flexible circuit board further includes a second thermally and electrically conducting layer that is disposed on a sensor surface opposite the contact surface of the first substrate layer and includes a sensor element connected to the sensor surface. The sensor element is configured to record a temperature of the pin-shaped electrical contact element when the pin-shaped electrical contact element is at least partially disposed in the opening.

  • Publication number: 20220258636
    Abstract: A method for charging an electrically powered vehicle includes predetermining a maximum charging current of a charging process for charging the vehicle before the start of the charging process based on an electrical resistance of at least one interface component of an interface between a charging device and the vehicle. The electrical resistance is determined during at least one previous charging process. The method further includes charging the electrically powered vehicle based on the predetermined maximum charging current.
