It was my understanding that the cigarette lighter socket is disconnected from the battery via software-controlled circuit after the car has been switched off for a period of time. The last BMWs you could actually charge through the cigarette lighter 24x7 are the E85/E86 Z4 M Coupe and E46 M3, which are pretty old now.
Please let me know if that's not the case and it's been confirmed that we can indeed use a trickle charger via the cigarette lighter socket. I'd be genuinely surprised if it's supported in any F-series BMW.
