How many kw/h to charge from zero

[David NZ]

Tried to search this on Forum but no luck. Apologies if been thrashed out before.
My 220v charger shows kw/h used and time taken to charge.
From flat or zero on car gauge it uses about 6kw/h to charge to full. With an 8.8kw battery is this about normal?
Ps. Is a 2017 with 58k km (36k miles) and shows 38km ( 23 miles) when fully charged.

That sounds about right.

My 220V L2 charger logs show that I generally use 5.8kWh to charge my battery from dead. Keep in mind that my car has 50k miles on the clock and I can barely squeeze 15 miles of pure EV range.

The battery will not go below a certain minimum charge level. I have a 2017 as well, with a meter on the charger outlet. 6kwh to charge is similar to what I’ve noticed.

I average about 6.2kWh. 88,000 miles. 21-24 miles during summer, 14-17 during winter. Sub 0 temperatures this week in Colorado.

David,
Have you determined your actual EV miles with a full charge? 23 miles on the meter is pretty good. I have a 2017 as well and had the EV battery replaced about a year ago. Though my meter shows 26mi after a charge, my actual is about 21-22 EV miles.

 

[billybaroo617]

Max calculated range (according to car’s dashboard) on our 2017, which has just over 100k miles on it, is 25-26 miles in mild temps. Actual range with no AC running is slightly less, even when driven gingerly. This seems to be a better max EV range than I see others posting in the forum. My theory is that, since the car has been charged using a level one charger for most of its life, that has helped the battery’s longevity.

Driving carefully with no AC I squeeze out about 20mile (30km) at 24deg in Summer here in New Zealand. Original battery, and never been much better than that, which is ok with me as my trip to work is only 6km.

Thanks so I’m normal.

My 2017 with 23,000 miles tops up at 24 miles - and used 2 of those miles just to get out of the garage and go about 1/2 mile. I think this is a parallel to an ICE Golf I own - as the MPG in the first 3 to 4 miles is 12 MPG then as the car warms up - it get almost double that to 23 mpg And of course if I am in City traffic - less MPG - and up to 30 MPG steady 65 MPH on a open highway.

As most of you know, after starting the A3 with no accessories - the 24 mile range is good in warm weather, but the real rang depends on Speed and up and down hills and Coasting etc.

But without leaving the garage turn on the Heat (above 66 degrees) or A/C system and the range drops to 22 without moving. Ad Headlights - wipers - seat heat - etc - and it will drop to 20 range. The computer is recalculating the "Expected" range based on the anticipated accessory drain - even before you engage the Drive. Add Cold weather and all the numbers go down.

Yes, about what I experience. My mileage also drops 1 km if I listen to early 2000's rock music. And how do you have only 23,000 on a 2017?

 

[Jacks A3 ET]

It only had 21400 miles when I bought it last year - after 4 owners!
Based on its history I assume all Owners saw this as a in town run about... Or it was a car left at Second home and only use part time. It is our every day around town car. Second car takes us on long trips, in Canada now...

Nice find. Stop by Burnaby Mountain on your next trip north.

just got a used 2018 A3 etron with 82k km, in Canada, nicely equipped technik ; at home i have a 220 v set up and using 12A charger (15A breaker) and takes 2hr 20min to charge...don't know how many kwh the car is accepting at home although i have one charge point charge of 5.7kwh.

at home I was getting on the dash 33/34km...as i try to figure out real life kms vs the calculated estimate....learning here...i was able to get 33km actual on 33km estimate...usually it doesn't come close but i had a longer 43km trip.

When i returned home and recharged the dash shows the highest amount i have seen todate, 39kms...probably the computer is using this recent actual to recompute to a higher figure...i don't know if the 39k km is the new norm or not? i don't imagine the battery all of a sudden gets to accept more than 5.7kwr....so the 39km to empty is probably based on the math on recent actual history .

lastly, i was able to see a document that shows the useable portion of the batter to be 6.2kwh....which contradicts the 7.0kwh useable i read in a self study guide of Audi's. But it sounds like ill be able to charge 6kwh max into the car. Here in BC Canada, I pay $.14 per kwh....so a charge to full is 84c CAD. Charge point charges .30/kwh CAD and i paid $1.75Cad for the 5.7kwh charge.

is this 6kw/h a rounded figure?? does your charger gauge have a 3 decimal (or higher) ...from a charge point i got 5.6598kWh. Not sure if why i cant get to 6.2kWh if that is the max usable?

I think the main difference in charges are in how the battery management system uses the battery reserve. On average I charge 5.4 - 6.5 kWh when I plug in on "red". I don't typically hit red on any given trip however. This last Tuesday I was driving the car on engine for much of the day. I plugged in at night and it charged to 6.35 kWh. I pay about the same for electricity in colorado. .09/kwh or .13/kwh CAD. Here are a couple of exports from my Emporia charger, daily use and where I tried to find max charges.

Good to know. Thanks for taking the time to do all this in your reply

Your data must be some days with multiple fill ups. Ie 10 kWh vs a 8.8 battery. I assume you’re 5.4 to 6.5 averages are single charges from empty(red reserve).

Obviously the more electricity a guy can use from the battery the more miles one can go to empty.

My car is probably operating normal as I recently got 20mi on ev mode on a 27mi total trip. When I refilled it showed 24 mile range.

Thx again!

Morning Rick. You have to remember that the electric range is significantly impacted by ambient temperature. So, you may see 22-24 miles in the summer, but only 17-18 miles in the winter (or less). The key is to watch the battery gauge on the dash to make sure every led is lit after a full charge. That tells you the battery is in good shape. If you get to the point where you only see 3/4 of the LEDs lit after a full charge, go to a dealer and have your battery tested. You may be due for a new battery (which is covered under warranty much of the time). Have fun with your A3 etron.

Thanks for the reply, so far so good on that front as all eight little LED lights on the dash are lite up.

yes, the larger refills are multiple chargers. Cheers.
