Did you manage to identify the root cause yourself, or did you take it to a workshop?

I tried troubleshooting myself, but without the proper diagnostic tools for an EV, I was stabbing in the dark. I took it to a certified workshop. They found electrical wiring damage caused by rodents. They repaired the issue and eventually the repair cost was 290€

That sounds eerily familiar. I had similar symptoms with my old BMW i3. The error memory stored a fault, the car occasionally cut out, and power was definitely limited. It might be a heavily discharged or defective battery.
