Received a letter from BMW stating that BMW EVs with a CCS port will get access to Tesla chargers in 2025. Two separate adapters will be needed for AC (level 2) and DC (level 3) charging.

I got it as well

A good sign!

Also, BMW lawyers at work!

Did I miss something? Are they going to send both adapters?

The letter is affirming BMW's plan to onboard in 2025 and giving instruction on the two different types of adapters. It does not say anything about BMW's intent to provide adapters.

But it is kind of warning against cheap knockoffs.

As I understand it you will have to buy them. Not coming free

That too.

[iXLagrange]

As I see it the key sentence is on page 3 .. "We will notify you once BMW-certified NACS adapters become available." So yes, do not rush out and buy a cheap knockoff.

He made it seem like they are send the to us…

My cynical opinion is the only reason BMW sent out this letter to us now is for legal coverage in case people damage their cars by using 3rd party adapters.

The silver lining of them sending out this letter so early with no details on Supercharger access dates is that they might expect to be onboarded to the Tesla network sooner than expected.

I’m hopeful that we’ll get Supercharger access permission from Tesla in early 2025, but the official BMW approved adapters won’t be available until later 2025. So it’ll be up to us if we want to risk it with an unofficial adapter.

Does my theory make sense?

Im down with that. The Tesla-made adapters are in high demand. Nissan and Kia have stated onboarding dates. So, things are moving.

BMW are in my opinion 100% correct to guide vehicle users towards standards approved and certified products.

Messing with multi kW connectors like they are phone chargers is not clever.

On another note the Tesla public chargers in the UK get on really well with the iX (and i3). Well enough to sign up to the Tesla annual plan.

I can appreciate BMW warning us to wait to purchase an approved DCFC adapter for charging the iX at a Tesla S/C; but warning about a L1/L2 adapter makes little sense. Why? Well, every EVSE that we’re using at our homes; offices, etc. have plugs made by different manufacturers and BMW has made no comment about only using their own, branded EVSE. Plus, many of us have been using high quality Tesla to CCS1 adapters for years at ‘Destination’ chargers without any qualms from BMW.

I think the main issue here is that if someone use a L2 adapter on a supercharger, it can be catastrophic as the 400VDC will be routed to the car internal AC to DC charger. The NACS connector use the same 2 pins to carry the L2 240VAC current and the DC 400VDC supercharger current. With the CCS 1 connector, the DC and AC current are routed to different pins on the connector.

The AC and DC adapters are passive, the internal wiring is different in both case.

Those kind of things is why we got the letter. “We told you so” is the point of it.

When we are “allowed” to use the Tesla chargers I will probably use the adapter sent to me by Ford when I had the Ford Mach E. Can’t believe it wouldn’t work properly on the BMW-

One issue I can think of is that the Mach E top rated recharge speed is slower than BMW and the the Ford unit wouldn’t handle what the BMW asked for.

It’s possible the Ford adaptor would just limit the speed itself solving that problem.

I got the Ford for free, Hope BMW does the same.

did the Ford one come with any paperwork/specs? if it isn't officially rated for 500A or 205kW, don't assume the adapter will be smart enough to lower the power for you.

Tesla made the NACS adapter for Ford, right? Same adapter that Rivian and GM are using, right?

This is not correct.

The AC adapter is based on a J1772 connector (lacking DC pins) while the DC is based on CCS1. The two cannot be confused with each other as they look, connect, and function in completely different ways.

Agree. But the NACS connector is the same for AC and DC charging. I assume that you can insert the NACS male plug of a supercharger into NACS to J1772 adapter. Can you?

Yes (possibly maybe - see last updated comment)

The female side of the adapter on a CCS and J1772 will be the same, as they both take the single NACS connector spec (that is both AC and DC).

It's the car side / male plug that's (obviously) different.

The concern is: take a J1772 adapter, plug in a Supercharger cable - plug it into your car (clearly, this will make a complete physical connection from SC >> Adapter >> iX. I think a lot of people assumed that the system would not negotiate correctly, and activate DC power - but apparently that's not always the case with older Superchargers, and/or possibly in the way the Tesla system checks for DC access. There was a whole thread about this on the Rivian forum, and I can't recall if it was a Rivian (or a post from a different vehicle forum), but someone cooked their port doing this.

Unless the SC spec now has some kind of additional physical connector "key"? Maybe with V4 stalls? Maybe a revision?
