Actually, that reminds me: I read somewhere that the dc/dc is off when
the car is off and instead it uses the small solar panel on the roof to
try to keep the 12v battery charged.

Peri,
I have checked my (2011) Leaf with LeafSpy when in Acc mode and it does
not charge the aux battery, I saw the aux battery voltage declining
(and
a current out of the battery).
As soon as the car is started *or* the car is charging, then the aux
battery is being maintained by the DC/DC converter from the main pack.

Ok, I can answer some of the questions with respect to a Leaf.
1. Acc only: You press the start button without holding down the brake
pedal.
2. Acc charging: yes, heating I don't think so. (However there is a way
to do it remotely through their carwings system, never tried it.)
3. contactors: brake must be pressed while pressing start button
4. Acc only: pretty much everything seems to be working except heat and
drive.
5. don't know, but I would presume so or else the 12v battery would go
dead.
6. same answer as 5.
7. Not sure what you mean by "separately". There are several warnings
that I've seen over the years - low tire pressure, door ajar. There
really isn't much detail presented to the driver so I think you would
need to read the codes off a computer to get what you're looking for.

All AC EVs have the same basic components: Propulsion Batteries,
Auxiliary Battery, HV/Low voltage Converter/Charger, Inverter/Regen
Unit, AC Motor, Battery Charger, Mechanical Brakes, Throttle Pedal,
some type of ON/OFF/START switch. You get in the vehicle do something
to start the vehicle, put your foot on the throttle and go. My
questions are very specific. What happens when you do the things that
I ask. As an example: you get in your vehicle and want to listen to
the radio while the car is charging. How do you do it? Is it
possible
to listen to the radio while you charge the car. Can you run the
heater or AC unit? What must you do as a driver/owner to accomplish
these tasks? Some vehicles may let you do some things but others may
not. If you own a vehicle, what is the vehicle and will it allow the
tasks and what must you do to answer the questions.

Your questions are clear but your context is not. Are you asking
- what mass produced EVs do in general?
- what a specific EV does?
- what the generally assumed best practices are?
- what is physically required?
