BMW claims that the iX will be able to handle DC fast charging up to 200 kW.

With fast charging, the iX's battery will be able to charge from 10-80% in under 40 minutes and get 75 miles of range in only 10 minutes.

To make this happen BMW is partnering with EVgo to use their public charging network. EVgo has over 800 fast charging locations in the US. Qualifying fully electric BMW models will receive $100 in EVgo charging credit that can be used through the BMW Charging app at EVgo and partner network stations.

If you're charging at home, with a 11 kW Level 2 charging station BMW says it will take less than eleven hours to charge the iX's battery from 0 to 100 percent.

Some charts that show the iX's charging capability.

No trouble at all. Glad it's helpful!

Hi everyone, I'm new here and took ownership of a full option IX xDrive40 last week.
What is the recommended percentage to charge the battery for long lasting lifespan?
The dealer told me it's okay to charge to 100% because net capacity and gross capacity differ and so there is some margin automatically, but also not to leave it parked for too long charged at 100%. The My BMW app seems to recommend only 80% but that seems low , given the gross margin it would mean only 75% of the battery gross capacity. Given then not so brilliant range of the xDrive40 I'm more considering 85%. Thoughts? What do you do?

Stay between 20% and 80% is best. Charging up to 100% if you will use it immediately after. Reason is the stress on the plastic film between the 2 poles that increase by higher charging state. So reducing the time this happens helps. If you don't need the full charge, don't charge above 80%.

Some help to give you an idea on charging depending on the State of Charge of your battery with fast chargers, I put here the times needed for a iX40 to charge 10% of his battery capacity (7 kWh).

SOC	time
10->20	0:02:56​
20->30	0:03:09​
30->40	0:03:33​
40->50	0:04:02​
50->60	0:05:24​
60->70	0:05:46​
70->80	0:06:42​
80->90	0:10:09​

These are calculated with data of the chart above.
If possible, you can better stop charging at 70% and drive until 10% to start charging again.
Charging from 60% to 70% (7 kWh) takes about the same time as charging from 10% to 30% (14 kWh).

Thank you. I will charge up to 80% when at home then, and so only 100% when leaving right after for a long trip.
The 10% feels risky in case that fast charger you need, doesn't turn out to be functioning

"The 10% feels risky in case that fast charger you need, doesn't turn out to be functioning "
Indeed! you need to be very sure or have an alternative in near region.
In some apps in the EU, you can see if charging stations are free, operating or defective.
But never be 100% sure today. This is changing rapidly since the last 6 months.

Anyone has any charging speed numbers for 80-90% and 90->100%? I know it's going to be slow, but I'm going on holiday somewhere in the Pyrenees where the nearest fast charger is 117km and I'm expected to do some kms every day as well, so could get tight. There are a couple of 50kw's closer, could help me reach 100% on the way there.

Looking to my home charger from 11kW AC, it should be at least 11 kW. I don't see a slow down.

thanks. Good to know.

Are there any options that will charge faster? Or is an 11kW Level 2 charging station the max you can get for residential?

 

[shar]

Would you need that? I have only 7.3kw, it's more than fast enough for me. Most often I only charge 50->80%

 

[hans.olbrecht]

@shar
I dig in the log file of my home charger and find follow back.
I only charged the iX40 at 100% once. All the rest was until 80% max.
I limited the charging power to 14A on a 3 phase 230V system with N at that time.
The power was thus limited to 9,8 kW by myself and not by the car.
The charger logged the charged energy every 15 minutes.
You can find the graph below.

from 96% to 99% it took 15 min
Hope this will help on your holiday trip.

Why wouldn't I want to charge as fast as I possibly can?

 

[shar]

Because a DC fast charge installation is expensive to install, very expensive in terms of power grid subscription (at least where I live in Belgium). Are those extra costs worth it? For me it's a clear no. I only need fast charging on long distance travels, i.e. not at home.

Because regularly fast-charging a car battery can negatively impact battery performance and durability, although by how much exactly is subject to debate.
