OPERATING STATE MONITORING DEVICE FOR MONITORING A CONNECTING CABLE AND OPERATING STATE CONTROLLING METHOD FOR MONITORING AN OPERATING STATE OF A CONDUCTING CONNECTING CABLE

摘要

The present invention relates to an operating state monitoring device (1) for a connecting cable (2) having electroconductive conductors (3, 4, 5, 6, 7, 8, 9, 10) for the power supply of an electric consumer, in particular of an electric drive of a motor vehicle. It is essential for the invention that the operating state monitoring device (1) has Hall sensors (13, 14, 15, 16, 17, 18, 19, 20), which are each assigned to a single conductor (3, 4, 5, 6, 7, 8, 9, 10), and that operating states of the connecting cable (2) are determined by means of a differential measuring method, as part of which difference values are formed and evaluated from measuring signals of directly adjacent Hall sensors (13, 14, 15, 16, 17, 18, 19, 20).
