"Release Automatically" is about unlocking the charging cable so that you can unplug it from the car without first having to unlock the car.

As long as you don't have a timer active, it will charge until the target.

Thank you, I want to be sure that if the car is not driven for a while, but plugged into charger, that it will continue to charge when SOC drops below target.

If Release automatically is set, will it reconnect and charge if SOC drops below target?

I'm not using a timer

 

If the ignition is off, then it won't draw any power from the high voltage battery.

However, the GT also has a 12V battery which is only charged when the car is running. If you're not driving the car for a while (6 weeks per the manual) then the 12V may drain leaving the car unusable until it's recharged, requiring access to the frunk, which is powered by the 12V battery. I recommend you read this thread which discusses the 12V battery issue and ways to mitigate it: https://www.e-tronforum.com/threads/transport-anxiety.8263/

Yes I've read that thread (I was the OP) and I'm still unclear. I thought a software updated happened and that if necessary, the 12V will now charge when the car is plugged in. Apologies if I am misunderstanding something. I'm coming from 7 years with a Tesla which I always had plugged in and always maintained target SOC.

 

Charge to your target %, then you can force a SOC% drop by running the climate control remotely. Do it few times over a day(s).

 

Apologies if I'm not posing my question properly.
My question is: When the SOC drops below target, will the car keep charging whether or not Release Automatically is set or not set?

 

I'm suggesting a test regimen in order for you to answer your own question.

 

Understood

 

Unlike Tesla's the etron has minimal phantom drain, so I'm not sure how you expect the SOC to drop if you have the car turned off and secured. How long are you anticipating that the car will not be driven?

 

+1 I was on vacation for about 3 weeks, and I don't think the car dropped a single percent of charge.

 

The "leave at time X" timer setting is entirely voodoo.
I think the idea is that they think a less-charged battery will last longer, and thus they predict how much charging it'll need to get to the given state at the timer time, and they then don't even start charging until the time comes when it must start to reach the target at the given time.
The draw-back with this option is that if you suddenly find you have to leave at another, earlier, time, your car won't have the target charge.
So, this is entirely driven by engineers wanting to make you treat the batteries as kindly as possible, rather than any actual user needs/behaviors being optimized.

 

I never used timed charging in my Tesla and won’t be using it for the Audi. I have a 26 kW solar array so I don’t need to worry about staggered energy rates.

 

I tried this… And yes, agree, it’s not very helpful… And you can make it every day based on a timer. Why not a normal timer: set a charging start and stop time and it charges what it can during that time.

I’ve got an electricity rate really low from 10 am to 3 pm, so I can see how that might work, but I don’t have a wall box and unlikely going to install one as the car came with 6 years (5 years left) of free fast charging, so I’ll probably just use that. Financially it would not make any sense to install a home charger, unless for convenience…

If you drive only a little bit, maybe you spend 30 minutes a week of your time charging.

Driveway charging takes 0 minutes of your time. I spend 0 minutes a week charging. This is a massive improvement to quality of life. With a > $100k car, you owe it to yourself to get a $300 wall charger and whatever your elechicken charges for the install...
