12V sockets power source on the hybrid

Going camping and wondering if the 12v outlets work off the hybrid Battery or the 12v Battery?

I'd say it depends if the car is in the Ready state or not. As I understand it the hybrid Battery supplies all the power but only when in the Ready state otherwise it's the 12v Battery.

Thanks for the answer, it's good to know ahead of the trip. Wouldn't want to drain the wrong Battery 😄

The 12V Battery won't last very long at all unless the car is in READY mode, when the petrol engine will kick in as and when needed to keep it topped up. If you just leave the car in ACC mode it'll either flatten the 12V Battery or switch things off to prevent that happening.

A conventional car has a starter motor to crank the engine and an alternator to run the 12V systems and keep the Battery charged when it's running.

The hybrid doesn't have either of those. The 12V Battery boots the computers and gets the hybrid system up and running in READY mode, which is our equivalent of the engine running.

A DC/DC converter takes power from the high voltage traction Battery and converts it to about 14.5V to run all the 12V systems and keep the 12V Battery charged up. If they hybrid system sees that the 12V Battery or the traction Battery is getting low, it will energise MG1 and use that to spin up the petrol engine to 1,000rpm before applying fuel and a spark to fire it, and it will run the engine until the batteries have reached a certain charge level, then stop it, and then repeat the cycle ad infinitum.
