Twingo Electric Overvoltage Fault

I'm experiencing an issue with my 2022 Renault Twingo Electric. It has 205686 km. I'm getting fault memory entries indicating an overvoltage condition, leading to system failures. The car battery seems weak when starting and generates a general electrical malfunction. Could this be a circuit protection or voltage regulator issue?

Hey, I also have a Twingo. I had something similar happen a while back. Lots of weird electrical stuff going haywire and overvoltage warnings. Was the battery heavily discharged at any point?

Yes, there have been instances where the battery was nearly completely drained. Could this be the core of the problem? Also, do you remember the repair cost?

A deeply discharged or defective battery can cause overvoltage issues when the system tries to compensate. The car might be trying too hard to charge a failing battery. I had to replace the battery, and it cost 290€. I recommend taking it to a workshop to get it checked out properly though.

Thanks for the insight. I will consider your experiences and bring the Twingo to a workshop for a thorough inspection of the car battery and electrical system. I will share the resolution after the repair.
