Hello, just picked up our etron. Wondering about charging options at home and whether i need to upgrade to 240 for our daily charging needs and what charger (if any) you all recommend.

Is the included one enough? I would like to keep it in the car but would like the convenience of having a charger at home.

Many options on the market but not sure which is better or worth it.

i appreciate your feedback and thanks for having me!

Home charger

I bought the JuiceBox Pro 40 a few weeks ago and it appears to be well-built, easy to install(for the electrician) and the app works well. I didn't want to keep moving the Audi charger for the car to the wall. The JuiceBox charges a lot quicker too.

It's easy to program if you want to time shift charging to off-peak hours. That's one of the reasons I bought it, but then found out my electric utility company's off-peak plan doubles the day rate to discount the off-peak rate. I don't have anything else in my home that would benefit for the lower night rate, so I didn't go on the plan. They told me they were going to be upgrading their system to provide complete energy usage by the hour to customers in a few months so I would able to see exactly what the charging is costing me.

Loving my e-tron! Going on three weeks gas-free.

Thanks so much for the information!

I am in the same situation, i want to keep the factory one in the car. That charger looks well built! Going to order one.

cheers!

Home Charging

I had installed a 240v outlet in the garage and am using the charger Audi provides. Works perfectly well. For me, following the Audi guideline of not charging until the battery is below 50% and limiting the max charge to 80%, I find I only need to charge it every 3 or 4 days. The Audi charger is quick to set up and disconnect if I feel I might need it on the road. Most likely, if I didn't use it at home, it would never be used! Quite a waste of money!

I use the Audi Charger

It is a definite advantage to install a 240 charger plug at home. I use the one supplied by Audi, but the ChargePoint would work well also. But make sure that you get the NEMA 14-50 plug. They offer both, but the NEMA 14-50 plug is the most recent technology. The plug for the Audi charger is a NEMA 14-50 plug. I do most of my charging at home - just plug it in at night and charge in the off-peak hours. The ChargePoint (and many others) allow you to use your phone to see the state of charge and to set up the charge timers.

Charging

You definitely want to install 240. Most utilities offer some cost sharing for the installation as well as a charger. I’m just using the charger provided. It also provides timer settings, etc. The only time I take the charger is out of town trips which is infrequent. While I do love my E Tron, would be better with another 100 miles of range.

Some extra help from the US Feds

2020 might be a good year to install that 240V EV charger here in the USA. Congress just re-passed an expired tax credit for installing a home EV charger - a 30% tax credit up to $1000. The typical charger + 220V line is about $800 - $1200, so you would get a tax credit of $240 - $360 payment on your 2020 tax return. It passed in December, so you can get the credit for the 2019 tax year. My install was a $1000, so I'm looking at extra $300 plus the $7500 for buying the e-tron. Doing my taxes early this year!

By the way, check out your utility company for any rebates. My little village run electric company gives up to a $250 cash rebate for installing a home EV charger

Just bought an Etron that I’m picking up tomorrow. I’m also moving in a month and don’t want to spend the money on 240 in my garage. I have a laundry room with an unused dryer outlet next to the garage. Will I be able to charge from there with the charger which comes with the car? Figure it’s close enough for a 15 foot cable.

Check with your electrical company about getting a free or greatly reduced price home 240 volt charger. I’m in Colorado and Holy Cross Energy gives you, yes gives you totally free a 240 ChargePoint charger.

We just got a new e-tron SUV (FL) and I have a 240 V dryer outlet in our garage. Can I just get an adapter so that the onboard charging cable that comes with the car can plug directly into the dryer outlet?

Yes. You'll just need an adapter for whatever connection your dryer has, such as NEMA 14-30P, for example. The included charger is NEMA 14-50P. Do note that charger can only do 100% (40A) or 50% (20A) when connected to 240V. And you want to allow for about 20% overhead for the outlet.

So if you have a 50A breaker, you'd set the charger for 40A. If it's a 30A breaker (common for Dryers), that would technically be 24A. But since there are only two settings, you'd need to drop down to 20A on the charger.

Thanks - I appreciate the help. We’re loving the e-tron but surprised that neither the dealership nor the national audi 800# were able to answer my pretty fundamental question. I guess they’re relatively new to this and will get up to speed over time.

Sort of? Most likely the dryer outlet is only rated for 30A. Yes, you can get an adapter that will let you plug the Audi compact charger into the dryer outlet. In older homes you likely have the 3-prong NEMA 10-30 outlet for the dryer, so you would need the adaptor to connect it to the NEMA 14-50 plug on the charger. However the Audi compact charger is rated at 240V/40A, while your dryer circuit is likely rated for 30A To get the maximum charging rate available from charger without setting your house on fire, you need to use 240V/50A circuit (EV chargers are specified for "continuous use", which means the circuit they are on must have an amperage 20% above the rated value--hence, the 40A charger needs to be on a 50A circuit). A 240/50 circuit uses a NEMA14-50 plug. Any charger rated at an amperage higher than that generally must be hardwired.

The "sort of" part? You can set the Audi compact charger to operate at "50%" of max (ie, this turns the Audi charger into a 240V/20A unit.) Thus, if you set the charger at "50%" you can use it on your 30A dryer circuit because it will pull a maximum amperage of only 20A (half of 40!). HOWEVER, it will charge your EV at only half the speed, compared to running it off a 50A (effectively 40) circuit. Now, it takes about 8 or 9 hours to go from 0 to 100% charge when set to 100%, so using the dryer circuit that will take abut 16 to 18 hours. The good part is that you almost NEVER charge at home from 0 to 100%. I generally charge when it drops below 50% and only charge up to the recommended 80% for daily use. So on your dryer circuit, that would be 6 or 7 hours--something you might be able to live with.

BOTTOM LINE: Do NOT try to use your dryer circuit (using an adapter) to supply the Audi Compact Charger if the charger is set to 100%. It will try to pull 40A from your 30A circuit and you will likely fry your circuit. Set the charger to "50%" so that it will only try to pull 20A.


To set the Audi compact charger to 50 percent, plug it into the wall and press and hold the Power button for several seconds (at least 5, as I recall). The Power button is dual function: short presses are for "On/Off"; the long presses are for "50%/100%".

I have used my Audi compact charger as my home charger since Nov 2019 and it works fine. My thinking about buying a different charger was that it made no sense having a perfectly good charger rotting in my frunk, when I can just unplug the Audi charger and toss it in the frunk if I think I might need it.

I would recommend getting a 240V/50A dedicated circuit installed. There may be times when charging at 20A just doesn't cut it.

Finally, congratulations on your new EV! I have a 2019 etron quattro SUV and love it. There is just a much steeper learning curve when moving from an ICE vehicle.
