The harder (read: higher amperage) you drive into the battery the more it will decay in terms of capacity. So just like a ICE car battery trickle charger, less is more in terms of pack longevity. Unless you are really fooling around we find we can get by using 50% almost all the time unless we only have a short time between needing to top up.

We’ve also readjusted to just letting it deplete somewhat and not charging fully (or even 80%) every night.

Same, I plug in at 50% power every few days. Car is up to 80% at least a couple hours before I'm awake in the morning :smile:

howdy all!

New e-tron owner here - when i charge to 100% ( which it sounds like i shouldn't ), i only see a range of 175 miles. Shouldn't i get at least 200 showing? And why only charge to 80% if audi already limited the battery usage to 80-85%?

thx

The range indicated is based largely on recent driving. If you are seeing that straight from the dealer it'll be low because the only driving the car has done has been in/out of cargo containers and test drives; less than ideal for range, haha.


As far as the 80% charge recommendation from Audi, the following article explains why that would be beneficial for the car:

According to several sources the e-tron has amazing liquid cooling and battery management, but the further you stay from the extreme ends of SoC, the better for the battery life.

Hey chrisjenx thanks for the tip about needing the long press to get from 50% to 100% when using the compact charger.

Why would it default to 50%? Wouldn't everyone want to charge at full power?

Is there any problem with charging at 100%?

I asked Audi Downtown Toronto dealership and they didn't know what I was talking about.
Thanks
Has to do with draw on house current. If you have a lot of devices vying for limited amount of energy, may not want 100% draw all the time. Not sure but 50% draws about 5.5 amps(?) and 100% draws 11 amps (or is it kw).

Hi all, Fast charged for the first time today at an Electrify America charger. I was at about 35%. The first charger I plugged into started around 50kW and slowly ramped up to about 120kW, All the time the cable was getting warmer and warmer. It then started rolling back the charge rate until it was back down to about 60kW. By that time I was at almost 70%. I stopped that charge and plugged in the cable on the other side of the machine that was cold. It started at 135kW and ramped up to 146kW until I hit 80% and then, as expected, started reducing the rate. The cable never got anywhere close to as warm as the first. I'm guessing either the first charger has a problem or there was a bad connection between the plug and my Etron. Anyone else experience different rates from different chargers of the same size?
