Will the 50e charge 12V from HV battery?
I’m waiting for delivery of my X5 50e, and wanting to put in an aftermarket front/rear camera monitoring system that’s always on. I’m wondering if anyone knows if the 50e will charge the 12V battery from the high-voltage battery while the car is parked (like my Tesla Model S would). I don’t want to drain the 12V battery if parked (like at the airport) for several days but also want the security monitoring.
It’s too bad that BMW does not allow for use of all its cameras for security recording like newer Teslas will. |

your purpose is best served by supplying power to the device through an external battery pack. search the forum and you will find several threads and posts of folks who hardwired their dash cams into the vehicle's power supply only to have to disconnect it, though a few have been successful through their intimate knowledge of electronics in general |
