Skoda Superb Hybrid High Voltage Error

I'm pulling my hair out! My 2019 Skoda Superb hybrid is throwing a high-voltage system error. The error is stored, and the engine keeps shutting off, leaving me with reduced engine power. I've done some digging, and it seems like a heavily discharged or defective battery might be the culprit. Any ideas?

A high-voltage system malfunction on a hybrid can be tricky. When did you first notice the battery warning? Were there any other electrical faults before the system malfunction?

Confirming a damaged cable can cause these symptoms in the high-voltage system of a hybrid. It's best to have a workshop inspect the system for cable damage or any other electrical fault.

The battery warning came on at the same time as the high-voltage system error. As for other electrical faults, the reduced engine power was pretty immediate. What specific electrical faults should I be looking for?

Problem solved! It was cable damage in the high-voltage system. A rodent had been chewing on it. The Skoda workshop replaced the cable, and the error messages are gone. Repair cost was 290€. Thanks for the assistance!
