Yes, on the T7 hybrid the engine battery is charged when charging the EV battery. It does not charge when you plug in the camping power cable, which is really annoying as you can end up with a dead engine battery even when you are plugged in. I will be taking my granny charger from now on.

In my case it works and increased from 50% to around 85-90% in a couple of hours with the socket cable not EV

On my T7 hybrid (a MY2026 collected a week ago) the engine battery charges when the camping power cable is connected. I know this as the van was sat on the drive for a week while we were in and out of it testing things and getting it all set up, packed and ready. The leisure battery and engine battery had dropped to around 70% each after a week of that with no driving. I connected the electric hook up cable to power and the next morning both the leisure battery and engine battery were back on 100%.

My TDI gets a battery boost ( vehicle and leisure) once a week using the electric hookup if I don't drive it.

That’s great to hear. When I asked the van centre they confirmed I have 2 days worth of recall works to do so I am hoping this includes changes so mine will charge this way as well!
