We are still using at home Level 1 charging (waiting for electrician!). When I started charging, and consulted the myAudi app, it estimated we would get to the 80% target in 58 hours. Whenever I check the status on the app, the estimated time is further out. We are now 18 hours longer that the initial estimated time for getting to the desired 80% charge.
We are newer owners, and this is only my second charging attempt. But I wonder if this constant extension of estimated charge time normal?? I did not wait for battery to get down to 20%, but started the charging at about 33%.
Sorry if this is a repeat question, but I did not easily find where this topic has been previously discussed.

You should charge every day, plug in whenever you get back, always. Like your iPhone. Nobody can wait for three days to refuel a car.

This is a good source for the calc. L1 rates are not much at ~4 miles per hour.

It's best not to let the battery run down so low. I limit mine to 80% max, as well. but try to keep my car above 50%. If you are using the Audi charger, is the display on the charger showing the charger is set for 100%, rather than 50% (charging voltage)--it's the illuminated number next to the Power button. If it is a 50%, press and hold the POWER button for about 5 sec to switch the charger to 100%.

Yes, the Audi charger is showing 100%. The myAudi app shows Charging Performance as 0.8kW. I hope there isn't evidence of bad wiring in our house or our e-tron.
And yes, I will charge more frequently - the lack of available miles almost caused a serious problem getting to a hospital in the middle of the night, so if I didn't have range anxiety previously, I might now. Luckily, electrician arrives in a couple days to add the L2 capable outlet.
Thanks for the comments on how to handle this more intelligently!

For some reason I also saw 0.8 kW when charging with the standard NEMA 5-15 plug.

12A * 120V = 1440 watts, or 1.4 kW. That's the expected output on a standard 16A line, since you can only use 80%, or 12A, for "continuous" use.
I suspect it is a built-in safety mechanism, since they expect owners will all be charging from 240V lines. Some BEVs, particularly older ones defaulted to lower amperages, just to be safe.

You should always use a dedicated circuit for charging, even at the reduced rate.

In the meantime, have you checked Plugshare for public L2 charging?

Edit: doh, I misunderstood JNealCox’s post on the reduced charge power option.

More good advice, thank you all. I haven't been using a dedicated circuit for the L1 charging. I did find a Plugshare (L2, I think) a couple miles away in a remote Park&Ride, but not in a location where I can watch over the car....

If you drive roughly the same way I do, your driving efficiency should be roughly 400 Wh per mile
So 800 W per hour charging gives you 2 miles per hour
Less in winter...

i just got my 2021 e tron, also charging with L1, also waiting for the electrician! My husband has a Tesla and it charges at home at a rate of about 4mi/hour. My Audi is showing 0.8kW charging performance as well. I’m not really sure how fast it’s “supposed” to charge with L1, but compared to the Tesla it’s reallllly slow. I’m really hoping it charges significantly faster with the level 2 installed.

Audi says, I think, that proper L1 charging to full battery should take about 18 hours. If you are using the Audi charger that came with the car, make sure the box has "100%" lit up. If "50%" is lit up, then press and hold the power button until the light switches to "100%".

The reallllly long and slow L1 charge time was no predictor of the L2 charging performance. My latest L2 - to go from 50% to 80% - took about 2.5 hours. Super simple process using the charger that came with our eTron.

Ok that’s good news! I’ve been worried that this slow charging time was an indication of L2 charging time. I’m still wondering if this is normal? I’m going back to the dealership to pick up a privacy trunk cover and have them show me a few other things, I’ll try to get more info about the slow charging times. Also, what brand of charging station did you get or are you just plugging into a regular 240 volt plug?

We had our electrician put in a 240V-50amp outlet near the car. We use the Audi charging station that came with the car. That is all that was needed.
However, the installation for the outlet was pretty high. But when the electrician came to bid on the job, he saw a tool in our garage that he needed (and we didn't). He said he'd drop several hundred dollars off the cost, and would move us up on his schedule if we'd sell him the tool. Happy on all sides.

Remember that you get a Federal tax credit towards the cost of intalling a 240V outlet for charging an EV at your residence. I don't know there is also a state credit in WA. I also you the charger that came with the car. It works fine!

Where did you find this info?

I did not know that! Thank you :) We also have a Tesla so we need to install some sort of charging station that can accommodate both EV’s.

Regarding L1 charging, I was told this by my Audi service. I think it is obscurely mentioned in the manual somewhere. IU briefly had to use L1 charging and had problems with it. When I would plug in the car it would switch to "waiting for timer" mode. However, the charger box also indicated it was set at 50%. Apparently at 50% on some circuits, the voltage is too low to initiate charging, so the car is fooled into thinking it has a timer set. Regarding the tax credit, which I believe was extended into 2021, "googling" EV tax credits is a good start!

I was recently at a place where L1 was my only option.
My winter range is average - about 180 miles if charged to 100%
when charging for 17 hours at 25 degrees F weather, i get about 20 - 22 miles of range
you should be careful in assiming that any 120v outlet is ok for L1 - older outlets are not “properly grounded”
for audi charger and it’ll not initiate a charging session
also, make sure to set your charger to 100%

That’s about what I’m getting in terms of range and L1 charge time. We are getting our charging station installed after the holidays, not sure if we will make the cutoff for the tax credit :/
Does your range ever jump up a minute or two after driving? I’m in seattle and it’s been in the low 40’s in the morning. Yesterday I was charged to 188 miles, I drove a few blocks and it had jumped to 196, Then I was coasting down hill and using regenerative breaking so I gained another mile to be at 197, then about 5 minutes and 1.5-2 miles later, I dropped back down to 188.
