  • Method and charging device for charging a high-voltage battery of an electric vehicle
    Patent number: 11945326
    Abstract: A method for charging a high-voltage battery of an electric vehicle, comprising: providing the high-voltage battery having a nominal battery voltage; providing a charging station outputting a DC charging voltage; selectively pre-charging a second charging terminal of the charging station to a predetermined pre-charge voltage using a controllably limited pre-charge current supplied by electric power from the high-voltage battery.
    Type: Grant
    Filed: December 18, 2020
    Date of Patent: April 2, 2024
    Assignees: PREH GMBA, BRUSA ELEKTRONIK AG
    Inventors: Marc Neitz, Alexander Matthias, Axel Krause, Andreas Kruspan, Marc Hanselmann, Hannes Hobi, Rudolf Meusburger
  • Method and charging device for charging a high-voltage battery of an electric vehicle
    Patent number: 11673482
    Abstract: A method for charging a high-voltage battery of an electric vehicle, comprising: providing the high-voltage battery having a nominal battery voltage; providing a charging station outputting a DC charging voltage less than the nominal battery voltage; draining current between a first battery terminal and a protective earth terminal such that the voltage between the first battery terminal and the protective earth terminal essentially matches with the voltage between a first charging terminal and the protective earth terminal, and boosting the voltage at a second charging terminal of the charging station to match the charging voltage with the nominal battery voltage.
