12v Battery capacity and charge type?

[BigApple]

Getting a 3ch dascam that has a higher draw then a normal 1ch.
to make sure I don’t drain my 12v battery during overnight parking as I hardwire it to the constant 12v. Does anyone know the capacity on the Macan ev turbo and how it is charged. Some ev’s Trickle charge the 12 v battery. Some only during driving. Some only during charging of the car. planning on adding a dashcam battery also but this may just lower the draw for a few hours. trying to avoid a big surprise on A 1-2 day of not driving and being in park mode.

I just spoke to a Porsche ambassador at a dealership. He told me the battery gets charged by an attenuator. And that is of course not the best thing for my scenario. The battery only charges based on the amount you drive. He also told me the battery is under the passengers footrest. It is strange that some of the fuse boxes are then located in the back. Unless some of the info is incorrect. The car is so new that most of all we do is a first for everyone else also.

This might be technically accurate, but is not useful. From the image in the manual, you can see where the battery is accessible from the frunk - the + connection is directly on the battery. It looks like you need to remove the whole frunk lining to get full access to the battery.

Hmm he told me that the pins are just pins in the frunk. It not the actual battery.

Looks like the battery is on the passenger side under the lining.

Interestingly in RHD drive cars the battery appears to be shifted over to stay on the passenger side.

In case that helps, @Joder is trying to install dashcams too. Discussion happening here.

Today I went to Audi and was told that the ppe platform structure charges the 12v battery also as the car is being charged. I wonder what is now true. What actually charges the 12v battery.

What they told you at Audi can be verified. Just use a multimeter between the poles of the 12V battery. It should measure between about 14V when you charge the vehicle and about 12.5 at rest.

That makes sense. I will test that shortly. Thank you.
