Anyone have issues with the AC charge limit. I have set my limit at the maximum and alternately turned the limit to off only to start my car at a later date and find the limit turned on and set to 6 amps.

[Road Trip]

Not having any issues myself. Sorry you are. I set my iX’s charging limit on its screen at 32 A; that is being echoed by my independent EVSE app with the latter regularly showing between 30.8A and 32A on my phone until I get a pop-up notice on my BMW app that the charging is complete.

I have mine set for 48 and consistently get 48. Sometimes it can change that setting after a software update. Maybe that is what happened.

[mfdutra]

Every time I park at a new location, the default limit goes back to 6, which is pathetic. Probably a software bug.

[Pictor]

Perhaps something going on with the profile? Does the car recognize you when you enter or are you showing up as Guest?

I charge at home at 11 kWh. Which is the max the iX can do.

Not to be pedantic, but it can do up to 22 kW in Europe, and other countries which have a different electric infrastructure than we have in North America.

To be pedantic, North America's standard supports up to 19.2kW but the iX only supports 11kW here because BMW hasn't opted to increase the size of the onboard charger

11kW is more than enough for most people. This is what I use a home unless I happen to park closer to the 9.6kW EVSE on the other side of my garage.

Actually there’s an option to select 22kW charging and in the UK at least it’s an included option with the M60. But not that many houses have 3 phase electrical supply to support the 22kW chargers so it’s not a popularly specced option on non M60s.

I think the AC charging limiting factor is mainly the limit of the circuit/gauge of the wire. My impression is that Most of the house hold 220V circuit are limited to 50A... correct me if I am wrong. Of coure one can choose to install wires of much higher gauge, but it's rare and unnecessary for most of the scenarios. One (extreme) analogy is like installing a fallout shelter in one's basement...

I made an observation today. When I park at home it reflects a 48amp limit, which is how I have it set. When I park away from home it defaults to 6amp. I suspect there is some logic to the AC default.

I've been learning a lot on these international BMW forums. The Nordic guys thought it was crazy that the US iX could only charge up to 11kw. But after some digging we learned that they have three phase electrical supply in their homes by default so they can easily get 22kw. We never see this in the US except for industrial locations.

Anyways, the charger in my condo is only 6kw, and I've never had any concerns about reaching my desired SOC overnight!

The wires inside your home are very specific to their own use case. So your electric oven or electric clothes dryer will have a wire gauged for that specific use.

If you're talking wiring from the street to your service panel, that's entirely different and will often depend on how big your house is, does it have a pool, or when was it built. These days, 200A is quite common but homes built even a few decades ago might have 100A service.

So for EV's we're concerned with capacity in the service panel in terms of space and available energy. It's pretty rare for a home with a 200A service to ever use that much at once so even if you think your panel may be 'full', you probably have capacity to add a 50A, 60A, or higher circuit which will mean a new run of wire from the service panel appropriate for the use case rather than using anything existing. But the typically largest circuit in a home would be 50A for your electric oven, yes. But, that's changing as there is a shift to more electric appliances.

That is very odd. I'll charge at home at (typically) 11kW but at work it's a 6kW (30amp) EVSE and the car uses it fully not defaulting to 6amp. At all times, my car is set to the 48amp limit.

I need to double check next time…perhaps it read 6kw…. I just made a quick mental note that it was different that what was set…

I have been tracking the changes and it appears everytime you park someplace new it reverts to 6 amps. Once you have changed it at a particulat location it seems to keep that setting.

[Pictor]

I'll double check tonight as I go to a new location but I don't believe my 2023 has ever defaulted to 6amps.

Anyone here in Europe, who can charge on AC at 22 kw? I was charging twice today on public charger with max rate of 22kw, but the car only charged at 11kw (xdrive40)...

The 22kw "AC Fast Charging" is an option you can purchase for the iX in Europe.

[Road Trip]

I wonder why we cannot get it in the U.S.

I think it's pointless because we don't have three phase charging in our homes in North America. Many European homes have it by default, so they can easily take advantage of this option. They can safely do 240v x 3 phase x 32 Amps = ~ 22kw. We can typically do 240V x 1 phase x 32Amps = 7kw, and if we pull a special line for our EVSE we can do 240V x 1 x 48 amps = ~11kw. Even at a safe, low amperage of 32 amps, Europeans can get ~22kw fast AC charging at home without much heat or fire risk.

It's a location based setting - move to a new location and it returns to a default 6A. Change it to say 48A and return to the same location it should be 48A.

e.g. I charge at 32A at home and 48A at work

I don't believe that's universally true. I can now confirm that my 2023 xDrive50 stays at the 48A default even when I go to another (or new) location.

As to why no 22kW in the US? The simple answer is that the standard for J1772 safely supports 19.2kW over the US standard split phase 240v. BMW hasn't offered us anything faster than the 11kW we get now. Porsche does offer 19.2kW as an option.

Interestingly, J3400 appears to be limited to 11.5kW over 240v but will support 80A delivery using a three phase circuit although it only uses one of the phases to do so. This is similar to how homes in the US take 240v and splits it into two 120v legs to feed our standards 120v 15A outlets.
