Embodiment Construction

[0024] The drawing shows a schematic illustration of a motor vehicle 10 , which can be a passenger car, for example. Motor vehicle 10 may have one or more energy supply devices. In the example shown in the drawing, an energy store of a motor vehicle, in particular a high-voltage battery 12 , is provided as energy supply device. The high-voltage battery 12 can be electrically connected to a high-voltage on-board electrical system 14 . The high-voltage vehicle electrical network 14—or simply referred to as the vehicle electrical network 14—may have, for example, bus bars and / or wires through which the high-voltage voltage generated by the high-voltage battery 12 is conducted to (not shown in of) high volt electrical loads. In connection with the present invention, a high voltage voltage is to be understood as meaning a voltage whose value is greater than 60 volts, in particular greater than 200 volts, for example 400 volts. One of the high-voltage electrical loads can be, for...

Abstract

The invention relates to a method for protecting a high-voltage on-board electrical system (14) of a motor vehicle (10) for repair and / or maintenance work on the motor vehicle (10). The invention is based on the task of protecting a high-voltage vehicle electrical system by means of technical measures instead of technological measures. In the method, during or after a voltage disconnection of the high-voltage on-board electrical system (14), wherein the energy input source of the energy supply device (12) to the high-voltage on-board electrical system is interrupted, the energy input of the energy supply device (12) is blocked source. Additionally or alternatively to this, at least another energy input source (16, 20, 32, 34, 38) is locked, wherein the at least another energy input source (16, 20, 32, 34, 38) is designed for , providing energy from another energy source (22) to the high-voltage vehicle electrical network (14).

Description

technical field [0001] The invention relates to a method for protecting a high-voltage / high-voltage on-board electrical system of a motor vehicle for repair and / or maintenance work on the motor vehicle. Also belonging to the invention are a motor vehicle with a high-voltage on-board electrical system and a diagnostic device for such a motor vehicle. Background technique [0002] During operation on or in the vicinity of high-voltage systems of the motor vehicle, it must be ensured that the system is voltage-free. A voltage disconnection is implemented for this purpose. The first important step here is to interrupt the connection between the high-voltage battery of the high-voltage system and the high-voltage vehicle electrical system for distributing the high voltage in the motor vehicle. For this purpose, a switching contactor is usually provided in the high-voltage battery, which is opened by the control device. This locks the electrical energy of the high-voltage batte...
