Zoe Undervoltage Issue

Hey, I've got a 2021 Renault Zoe (electric) that's acting super weird. It starts sluggishly, systems are throwing errors, lights flicker, and the battery seems weak on startup. Mileage is at 70613 km. Could this be a voltage regulator thing? It feels like something's not getting enough power.

Sounds like undervoltage. Have you checked the battery's voltage? A heavily discharged or defective battery can cause these symptoms. Essentially, it's like trying to run a marathon on an empty stomach.

How would I check the battery voltage myself? Is it something I can do with a regular multimeter, or is it more complicated?

You can use a multimeter, but be careful. If you're not comfortable, it's best to take it to a workshop. Given the symptoms and mileage, and if you don't have experience with electronics, it might be the best option. Likely a defective/heavily discharged battery.

Thanks! I took it to a local mechanic, and you were spot on. The battery was indeed the culprit, undervoltage issue confirmed. New battery installed, and it cost me about 290€. Everything's running smoothly now. Appreciate the help!
