Hi - another charging question. We have had our 50e for a week now and continue learning more about charging options.

We have been using Chargepoint stations without issue but want to expand our options. There is an electrify america based charging station closest to our home but best I can tell, these are DC chargers (they have 2 different connector types at each station).

Question 1: Does anyone make an adapeter the will allow us to use these chargers on our 50e?

It seems Tesla has a different type of connector as well?

Question 2: Would this adaper let us use dedicated Tesla charging stations? [Only for J1772 EVs] Lectron - Tesla to J1772 Charger Adapter, Max 40 Amp & 250V - Compatible with Tesla High Powered Connector, Destination Charger, and Mobile Connector Only (Black) https://a.co/d/5mJCfTI

Appreciate the patience and help while we continue to learn about our new toy

50e cannot do DC fast charging. L2 AC is the fastest it will accept. The Lectron adapter is for Tesla destination charger (L2 AC) to adapt to J1772x so you can charge 50e. You cannot and should not use it at Tesla super charging stations.

A BEV will typically have a much larger battery, and because it doesn't have the ICE backup, having a quicker way to recharge is critical...thus, most all of them can be recharged slower with ACV, or faster with DCV. While the Tesla connector supports both, the J1772 uses two differently shaped plugs...the base connector does ACV, but the add-on bulge adds two HVDC contacts. Feeding HVDC into your 50e, if you managed to make it happen (tough, as the connectors are different and the protocol is too), you'd fry the electronics and maybe start a fire.

as mentioned:
Tesla Destination Charger stations (AC) = compatible with 50e
Tesla Supercharger stations (DC) = NOT compatible with 50e

do not use an adapter to charge via a Tesla AC charger. If anything goes wrong and it is determined that using an adapter caused the issue, there is a risk that your warranty will be voided.

that is a good point this recently happened to someone. he was having charging issues, and their dealership saw the adapter in the cargo area and blamed the charging issues on that and wouldn’t cover repairs under warranty

question is don’t they need to prove the adapter caused the issue in order to void a warranty claim?

but is that a necessary risk? If you don't use it, there won't be any issues.

if they used “third party” accessories as their reason, then the majority of us with non-BMW chargers at home would also be denied a warranty claim, but they’re not asking “what charger do you use at home?”

BMW is part of the EVGo network. if they claim use of third party accessories invalidates warranty claims, how are those chargers exempt?

[eelnoraa]

But isn't it too far of reach on the assumption?? Like saying if you use a non BMW brand oil, you can void warranty?

First having the adaptor in trunk doesn't mean it has been used. Like having a gun doesn't mean you have killed someone. Then they also need to prove L2 tesla EVSE can actually damage anything at all, which can only be proved otherwise. Now if the detected a high voltage DC damage, I think this is the only possible reason to void warranty

The Tesla level 2 charger would require an adapter to charge a BMW. It can do it, but using the adapter could result in a voiding of the warranty. Because the Tesla level 2 charger on its own only works with Teslas. Getting a WallBox charger at home to charge you 50e isn't a problem.

Charging protocol itself is basically the same. If the adapter is crap and causes a problem, then that makes sense, but you have that risk with any charger. Handles are not super robust.

[eelnoraa]

Not even “basically” the same. The L2 handling is exactly the same. Tesla car can use adapters on J1772 to charge itself. Tesla themselves now also make a J1772 EVSE with a Tesla adapter.

I'm just providing the information, I'm not arguing anything. Do what you wish with the information

Do you have a source for your information?
Just find it hard to believe.
And to be honest, there is no way that they can prove that you have used or not used any adapter.

And it is inevitable that BMW would also switch to Tesla charger (NACS) in the future for North America, and adapters would be the norm.

Agreed. Just pointing out that it's often hard to diagnose a failure like that after the fact without access to the charger data, and the same identical failure could come from a Tesla or a non-Tesla charger pretty easily. Maybe the takeaway is don't share with the dealer the details of your charger.

there is a lot of data that's available through the myBMW app that stores charging sessions, locations, etc. Take a look at that detail and see if the type of home charger is listed (if you're using a Tesla home charger). I don't know that answer to that, but assume that there is more data than is shown to the consumer.

[eelnoraa]

Tesla does make a J1772 wall charger tho
https://shop.tesla.com/product/j1772-wall-connector

And I don’t think J1772 is capable of making any communication to the car other than pilot signal to negotiate charging current.

[jad03060]

Other than interlocks, acv charging with J1772 is pretty dumb.

There's a bit more info passed with CCS charging, but the X5 doesn't support that.

Tesla has the ability to exchange data with the vehicle via serial data path to authenticate the use of one of their units. While I've not used it, the Tesla to J1772 adapter I have says to attach the adapter and wait for it to communicate with the unit before attaching it to the vehicle. I bought it on a whim on sale for that just in case situation where I was going to be overnight with a Tesla destination charger, or visiting a friend that was willing to let me recharge while there.
