Traveller Electric Battery Voltage Issue
Summary of the thread
The conversation revolves around a 2023 Peugeot Traveller with an electric engine experiencing weak battery starts and flickering lights, suspected to be due to low voltage. A possible cause identified is a faulty battery voltage sensor, which can lead to inaccurate readings and these symptoms. It is suggested to have the vehicle professionally diagnosed and potentially replace the sensor, as handling electrical components in electric vehicles can be complex and hazardous.

Thanks for the info! I haven't checked the voltage readings myself, as I don't have a multimeter. Is the voltage sensor something that's easy to check or replace, or is it better left to a professional? I am only vaguely familiar with vehicle diagnostics.

Okay, I understand. While you could try to check the sensor yourself, it's often integrated into the battery management system and requires specialized tools to diagnose properly. Plus, incorrect handling of electrical components in an electric vehicle can be dangerous. Given your symptoms and my experience with the Megane, it really sounds like a defective battery sensor. I ended up having to get mine replaced. I'd highly recommend taking it to a workshop for a proper diagnostic.

Appreciate the advice! I'll take it to a workshop and have them check the battery sensor. Sounds like the best course of action. Thanks again for sharing your experience! It's probably going to cost me around 315€, but at least I'll have peace of mind.

Hey there! I had a similar issue with my older Renault Megane, although it was a petrol version. Weak starts and flickering lights often point to problems with the battery's voltage sensor. These sensors monitor the battery's health and communicate with the car's computer. When they fail, they can give inaccurate readings, leading to these symptoms. Have you checked the voltage readings? A healthy battery should be around 12.6 volts when the engine is off and closer to 14 volts when the engine is running.
