7.11.1. Overview
The HvShoCircMonr component monitors the high voltage powernet for short circuit faults. It compares the total current consumption of the HV consumers with the actual HV battery current. If the difference exceeds a defined threshold for a certain time, a short circuit fault is detected.

Short Circuit Fault Detection |
Detects a short circuit fault in the high voltage powernet by comparing the total current consumption with the actual battery current. If the difference exceeds a defined threshold for a certain time, a short circuit fault is indicated. The fault detection is only active if the communication with the HV consumers is not faulted. |
