Need more information but the short answer is no.
How are you charging? What EVSE do you have? Is the EVSE hard wired or connected to a (14-50) plug? If connected to a plug do you have a GFCI breaker in the path? What speed (kW) are you charging at? Is the EVSE stopping the charge or is the car? Is this outside in the sun or inside in the garage/carport? Have you tried another EVSE (at work or elsewhere)? ... The most common culprit is often the EVSE that's plugged into an outlet where NEC2020 code requires a GFCI. The EVSE has it's own fault detection and you may get false interrupts because of this. It's best to hardwire the EVSE if you can.

From reading these forums over the last 6 months the primary reason why charging stops if because there is too much amperage being pushed through your charger so it stops for safety reasons. Can you try reducing the maximum amperage so it can charge a little slow and cooler? I bet that will work!

Any issues with charging being interrupted likely have to do with your wiring and charger installation. Go and charge the car on another L2 at the same rate and see if you get the same error. That removes your wiring and charger as variables. |

Had this. My vehicle bricked and was towed the next day. Dealer took a few weeks to try to repair. Ended up replacing ccu. BMW bought this vehicle back from me so no update on if that definitively fixed error

On a simpler note, check the obvious first - schedules set on the charger, the charger app or MyBMW app, or in the car. And it would help to have a little more - as in any - information: type of EVSE ("charger"), settings, when it gets interrupted (immediately, one hour in, middle of the night), GFCI thrown, after 50%, 70%, 80%, same time each time, randomly, sometimes, all the time, type of connection? Like that.

Charging interruption
Thank you for your responses to my problem. I took delivery of my IX last November and then charge the vehicle successfully at my home location until recently. Now each time I start the charging process it gets interrupted several times during the process. What is strange the charging process starts up again when I walk towards the car with my digital key. Any ideas?

I had one interruption during charging in the past. Do not know the cause. The charging was resumed automatically and suffered no dedays. The only reason I know such interruption existed is because the charge started timestamp was modified. It could be a software issue on the BMW server side.
When charging is stopped for awhile, the car will eventually go to sleep mode. As a UWB key move approaches the car will wake up and realize it hasn't reach the charging target while plug-in so it reinitiates the charging process from what's leftover. |

1) Sudden surging current from lightning. Proper grounding should prevent that. 2) Power grid brown out. When every connected devices attempt to power up from a blackout, the grid can't provide instant juice for everything. It will cause sudden and sometimes sustained level of low voltage output. It can melt any coils or high resistant components. When that happens, ideally it should either protected by the wall charger circuits or demage the wall charger first. If somehow it passed through, things would get wierd with the oboard charger and software controls. |

So it looks like it charges an hour or so, then stops. Not the GFCI - it would stay off. What type of EVSE and how is it connected? Outlet, hard wired? Settings in your MyBMW app? Have you tried charging elsewhere successfully (rules out car)? Resetting the EVSE? Tried the BMW included EVSE to see if that works (if you have a 240v outlet - if not, just see if the charging disconnects with 120v)? Any info when you expand the "Charging interrupted" dialog boxes above?

Does it happen only at home? Or also when you charge at other level 2 chargers?
If it’s only home I would think there is something wrong with the charger/wiring/breaker. |

I've seen a similar issue with my iX I haven't gotten to the bottom of. The frustrating part is that there is no info in the app/car about why charging was interrupted. So I have no idea what to try and fix with wiring and/or EVSE.
At home and destination level 2 chargers I've never seen a charging fault. Car always charges 100% reliably. At our cabin, I see charging interrupted 20-30% of the time. If I unplug/replug the car charging starts back up again. It's unlikely to be an amperage issue. I have a 50 amp charger on a 40 amp breaker. The charger is correctly configured to max out at 32 amps for the 40 amp circuit. The charger is a Grizzl-E, which have generally been well reviewed. |

I see charging stop for a while on my home chargepoint flex and at a FLO level 2 I use sometimes. The charge resumes after a few minutes break. I don't know if it's for cooling or what.
I was concerned at first when going outside and seeing charging stopped. I called FLO support and they told me it was normal. It does start charging again just fine after a few minutes. I'm interested whether other level 2 chargers act the same? |

Do you have the plug and go software update and has this always been the case? I’ve never had issue at home or anywhere until after plug and go I stopped being able to charge on my own home level 2 but only on that level 2. I’ve ruled out charger and within reason the car but currently at shop being updated.

Both ClipperCreek (now Enphase) L2 EVSE start charging within seconds of plugging in and don't stop until I hit the charge limit or I stop the charge. This is at a full 11kW or 9kW depending on which one of the two L2 chargers I have at home. The one exception is if I get a phantom trip of the GFCI on the plug in 9kW EVSE which doesn't happen often but it it has occurred in the past. In that case it stops until I reset the GFCI. It's been probably six months since the last phantom trip. My experience with commercial L2 EVSEs have been similar. Plug in and it charges until full. The exception is with ChargePoint commercial L2 EVSE when the load is shared between two plugs, If the unit is configured to share power then I may start at 6kW but then when someone else plugs into the second handle, I notice the charge rate drops to 0 for a minute before going back to 3kW.
