  • Method for deactivating a high voltage system of a motor vehicle
    Patent number: 9873331
    Abstract: A method for deactivating an electric high voltage system of a motor vehicle including requesting an interruption of the high voltage system in a first control system; requesting an interruption of the high voltage system in a second control system; and the automatic interruption of the high voltage system by at least one of the control systems.
    Type: Grant
    Filed: June 19, 2013
    Date of Patent: January 23, 2018
    Assignee: Volkwagen AG
    Inventors: Uwe Lachmund, Ronny Hänsch, Stefan Quentmeier
  • Method and device for monitoring a high-voltage arrangement
    Patent number: 9588164
    Abstract: Devices and methods for monitoring a high-voltage arrangement wherein a current loop runs through elements of the high-voltage arrangement that are monitored. Voltages are sensed on at least three points of the current loop. On the basis of the sensed voltages, an interruption of the current loop is detected and, in response, a high-voltage supply is interrupted. The interruption is localized on the basis of the sensed voltages.

  • Method for determining the absence of voltage in an electrical high-voltage system, and electrical high-voltage system
    Patent number: 9500680
    Abstract: A method for determining the absence of voltage in an electrical high-voltage system, in particular in an electric or hybrid vehicle, by using at least two control units in the high-voltage system and at least one display unit, wherein the control units detect the voltage in the high-voltage system independently of one another, wherein an absence of voltage is displayed on the display unit only if both control units detect a voltage below a threshold value. Also disclosed is an electrical high-voltage system.
