Method for operating a motor vehicle for a predetermined period of time after deactivating a high-voltage battery of the motor vehicle and motor vehicle with a control unit which is designed to carry out such a method

摘要

The invention relates to a method for operating a motor vehicle (10) for a predetermined period of time after a high-voltage battery (34) of the motor vehicle (10) has been deactivated, and to the motor vehicle (10) with a control unit (20) that is designed for such a method perform. The method comprises the following method steps: determining that the high-voltage battery (34) is deactivated while the motor vehicle (10) is traveling on a charging street (12) (S1), the charging street (12) having at least charging sections (14) leading to contactless charging are configured, as well as providing a secondary voltage in a high-voltage on-board network (30) and a tertiary voltage in a low-voltage on-board network (40) of the motor vehicle (10), each of which is above a predetermined minimum voltage, by means of a motor control device (32) by at least one of an electric drive machine ( 31) electrical quantity provided by an inverter (33) is limited to a predetermined maximum emergency value that is smaller than a predetermined maximum value (S2).
