Method for monitoring high voltage components of electrical system of electrical vehicle, involves checking plug connections automatically to obtain plug connector test result, and comparing result with cable set test result

摘要

The method involves checking plug connections (HS, HB) automatically by a plug connector tester to obtain a plug connector test result, where the plug connections electrically connect high voltage components (HV1-HVm) with a cable set (LS). The cable set is automatically checked by a preset voltage applied to an electrical system. Voltage and/or current (I) in or at the components are/is measured, and measurement values are compared with given values, so as to obtain a cable set test result. The plug connector test result is compared with the cable set test result. An independent claim is also included for a device for monitoring high voltage components of an electrical system of a vehicle, comprising a plug connector tester.
