Abstract

Official abstract text for this publication.

A method for testing a testing device for determining a voltage state of an on-board high-voltage electrical system of a motor vehicle includes establishing a predetermined voltage state in the on-board high-voltage electrical system by supplying a test voltage to the on-board high-voltage electrical system and determining the voltage state with the testing device and comparing the determined voltage state with the predetermined voltage state This ensures that, before maintenance work on the on-board high-voltage electrical system is performed, a voltage-free state of the on-board high-voltage electrical system determined by the testing device is actually present, thereby eliminating risk to maintenance personnel due to an accidentally applied voltage.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for determining with a testing device a safe voltage state of an on-board high-voltage electrical system of a motor vehicle, comprising: disconnecting a high-voltage source of the motor vehicle from the on-board high-voltage electrical system by opening a contactor thereby producing an isolated on-board high-voltage electrical system having a voltage-free state, and while the high-voltage source is disconnected from the isolated on-board high-volt…
