    I sometimes drive only 5 miles a week and the 12v battery goes dead. When it is dead is it possible to turn on the system and let the HV battery charge the 12v? Like leave it on for a few minutes?

    welcome!

    unfortunately, no.

    if you don't drive much, you should get a 12v battery maintainer, and leave it connected when not using the car.
