NOVELTY - The method involves comparing taken current with a value of an operating mode according to a variable comparison value. A high voltage battery is detachably electrically coupled with a high voltage component of a motor vehicle (2). The taken current is reduced when comparing to indicate that the taken current exceeds the comparison value around a predesignated deviation (X) (3). The high voltage component is provided with an electric line and/or an electric contact i.e. plug contact. Current carrying capacity of the electric line and/or contact is compared using the comparison value.    USE - Method for reducing taken current from a battery of a high voltage system of a motor vehicle (claimed).    ADVANTAGE - The method enables comparing the taken current with the value of the operating mode according to the variable comparison value, detachably electrically coupling the high voltage battery with the high voltage component of the motor vehicle, and reducing the taken current when comparing to indicate that the taken current exceeds the comparison value around the predesignated deviation, thus increasing working safety and flexibility of the high voltage system of the motor vehicle and reducing current consumption and potential endangerment of the high voltage system of the motor vehicle.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high voltage system for a motor vehicle.
