I’ve got my second hand Twizy three weeks now, and there is one thing that keeps bugging me. The 12V battery does not charge when the car is plugged in, and only starts to charge when I am driving at a higher speed. Which means that at EVERY traffic light the battery fault light comes on with a beep, only to dim when I am driving again. And that annoys me…
This evening I noticed something peculiar. While driving on a small country lane I saw my headlights burn brighter when I push the “gas” peddle. At that moment I hear a click like some relais comes into action and my battery-monitor-sigarette-ligther-thingy shows three LED’s, which indicates the 12V battery is charging at the specified rate.
The moment I let go of the peddle, I hear the relais click again, the headlights burn noticeably dimmer and the battery-thingy only shows one LED, indicating that the (new!) 12V battery is now delivering power without being charged.
I cannot find any electrical schema of the Twizy so I do not know how those 58V to 12V DC-DC converter is connected. I even do not know where that 12V is generated (is it done by the charger, or is it done somewhere in the large battery box?)
So is there anyone who can help me locate the problem? Anyone with some knowledge about the Twizy Electronics? Any help appreciated!
