Mechanical switches in high-voltage systems can fuse shut due to arcing or overcurrent without the controller's knowledge. Identifying this failure prevents unintended energization of high-voltage rails and potential thermal runaway.

Unintended electrical leakage between high-voltage battery components and the vehicle chassis poses significant safety risks and hardware damage. Detecting these insulation breakdowns ensures operational safety and prevents catastrophic electrical faults.

Inaccurate multi-channel sampling and signal gain fluctuations prevent reliable high-voltage monitoring. Resolving these measurement errors ensures precise leakage detection and prevents system safety failures.

Excessive current flow threatens the integrity of high-voltage vehicle components and electronic systems. Preventing these surges avoids catastrophic hardware failure and fire hazards.
