I purchased a new 2022 EQB300 in early September 2022. Overall, I like the performance and drive of the car despite relatively poor range (240 miles max but often much lower). What I cannot stand is how awful and cumbersome charging issues are here in the U.S. Any new MB EV vehicle comes with a 2 years of free charging at any Electrify America (EA) for 30 min sessions. What no one told me was how unreliable the EA network is. There is a EA charging station near my home where there are 10 chargers but only 3 were working this past weekend and even a few days later it is no different as nothing has been serviced. Even when you have what looks like a functional charging station, there are technical glitches almost half the time which necessitate calling EA and being on hold for long periods of time. Recently, I have had problems with the Mercedes Me Connect app. Every time I try to charge, I am told that I don't have a Mercedes Me Charge "contract" and need to register through Mercedes Me although I have completed all of this "registration" at the time of vehicle purchase. I called the Mercedes Me Connect support line and was told that they operate on a 48 hour timeline - how is this practical for on a customer service level and charging issue as one needs to be able to charge to go to work etc etc?

Hi, I got the EQB 350 AMG Pinnacle in Sept23. So far its a great car. EA charging was a learning curve. Had to call ea every time until I figured it out through a YouTube video. When I reach a EA Charger, I open my MeConnect App and go to the location menu (bottom right). It will zoom the map to your current location. Then tap the Charger Icon (bottom left) and the App will search in that location for available chargers and will show a green dot for each Charger that is available for your MB charge account. EA/Charge Point/EVgo. When at the EACharger, tap the green dot for that charger and you’ll see the available charging Stations. Find your Charger number in that listing and tap on it. You will get a blue charge button. Tap on it and the screen on the Charging unit will automatically ask you now to plug in. Do that and the charger will connect to your car and communicate the necessary information to get your free charging. So far so good. Most of the time it will work. But I experienced this also not working. I also have a Account with EA and when the Charger is displaying an error message or unavailable use of the app connect charging, your offered to charge as guest or Member. I tap Member(top left on charger screen) and hold my iphone (with the EA Account card in the Wallet App) against the reader and it starts charging. But this time it is collecting the money through your account. Not a free charge! I called EA about it and they said they will charge always when the account card is used. No refund! Only through the Mercedes me connect App initiated charges are free. I’m not happy with this issue. As the car is sold with free 30 min. Charging for 2 years on EA. with no ifs or buts at time of sale!! Called my mercedes sales rep. - Mercedes apparently has recently also heard of this issue and it’s new to them too. According to the rep. They working on it with EA. lets hope. Next time I have the issue that the charging station doesn’t connect through my Mercedes App, I will call the EA and they will help every time to get the free charging initiated. I hope this helps someone.

If not needed, recommend charging only to 80%. The time it takes to charge >80% rises dramatically, and probably isn't great for battery life-time, either. We get pretty good results at home with a basic cable and 240V output at 3.7kW and it usually can charge up to 80% overnight regardless of starting charge. Since my wife only drives about 60 miles round trip to work/kids/etc, we typically charge between 20-80%. Even only at 80%, we have sufficient charge for minimum 2 round-trip commutes, and may have enough for a third round trip but definitely enough for one-way. I just figure out the charge used per mile (or 100 miles to make it easier) - can see this on Mercedes Me app - which for us is around 30kWh/100 miles. This means that we typically get "only" 100 miles / 30kWh * 3.7kW = 12.3 miles per hour charging. For our typical 60 mile commute, this is just 5 hours of charging. If we charge to 100%, say before a planned long trip, it will take much longer beyond 80% and typically requires 8 hours or more depending on starting state of charge.

Interesting. In the ChargePoint app, there is a "Charge Current Limit" setting that allows the user to select the maximum amperage, which needs to align with the electrical output and the car--on my app it maxes out at 40A, which is where the electrician told me to set it when he installed the charger after upgrading our service line and panel. If there is no app for your charger, there must be another way to set the amperage limit (unless it is permanently set at your current output, in which case you probably cannot do much besides get a better charger). Could there be a way to change this setting manually on the product itself, maybe under a removable cover or otherwise out of sight?

To my knowledge there is not a way to use the Mercedes Me app to control amperage. It has three possible charging programs (home/work/standard) within which you can customize some settings but all the amperage settings for me are in the ChargePoint app. That's also where I do all of the programming (scheduling charging, etc.).

I'm no electrician so just reporting what I did at setup time...but it does seem like your issue may be tied to max amperage. Also, is your service level/panel for sure capable of putting out more amperage? We had to upgrade both in order to reliably put out 40A.

So, I am speculating here about this being a charger issue and not a car issue, but here is the thing with chargers. For a Level 2 charger to provide 9.6 KW at 240V, it needs to pull in 40A. If your charger is set for 30A max and say for some reason the input voltage is 200-220V at your charger, then the peak power is limited to between 6KW - 6.6KW. This could be why you are only getting 5.9 KW at the car.

I have a 440V 3 phase connection for the wall box and am able to pull in 11 KW, but only 1.7KW from the Level 1 home charger because it is limited to just 8A peak current.

Correct, and we checked that today it was pulling 30amps, however Tesla using the same charger is pulling 40 amps. How is that possible? I connected the home charger today to see it’s only pulling 1.3kW. Going from 76% to 100% in over 12 hours. If this is the charging situation with only my car, I think it might be a factory defect.

I purchased a brand new 2023 EQB300 and I am having a big charging issue with my Mercedes EQB. It is taking 9 hours to go from 20% charge to 100% charge at a Level 2 charger, If I charge it at home it is taking 3 days (start charge on Friday evening completed on Monday morning). I reported this issue to the local Mercedes dealer and they said it is charging as designed. I am wondering if it is really as designed or if it is a settings issue. I have set the program to work and set the maximum charging current to "maximum", even then it charges slow. I am missing something in the settings section here or is this a Mercedes issue?

I have also had issues a a variety of charging stations. BUT MY MAIN CONCERN is, my 2023 EQB300 has posted on the screen "CAN NOT LOAD CONTENT" 3 times since I have had it (took ownership April 7, 2023). 2 months after I got my car it WOULD NOT allow a charge at a public station, posting on the screen CAN NOT LOAD CONTENT, I pushed the Mercedes Me button and was told to lock and unlock my car 3 times then wait 10 minutes and try it again, that did nothing, so I took it directly to my Mercedes dealership and an appointment was set up for service; for 2 days I could not charge it (I could charge at home, however). On the way to dropping the car off at the dealership I tried again to charge it and it charged. When I got to the dealership I told them it was now charging and was told that if it was charging there wasn't anything they could do. It happened a second time while I was on vacation (only 1 day this time). Then it happened again last week, so I went directly to the Mercedes Dealership. An appointment was set up again, only this time my service rep told me even if it starts charging again to still bring it in. They had my car 6 days and when I picked it up I was told they couldn't find anything wrong. If I only traveled locally I guess I could just live with this, but I have children that live out of the area and now feel that I can't go visit them without the worry of getting stuck somewhere!
Has anyone else had this problem?????

For what it’s worth, I’ve owned the EQB here in the U.S. since September and have never experienced any of the issues that you have. I’ve successfully charged (complimentary) at EA 10-15 times in that period. Yes, I have had some issues connecting but most of the time it’s been user error. The EA locations are always available via MBUX but I have noticed they are missing from the app at times. Point of this post is to sympathize with you all but I did want to note I don’t think this is an issue with all EQBs.

I have been experiencing a more disturbing charging problem this week with my 2022 MB EQB300 at Electrify America. While we have all know that the Mercedes Connect Me is awful, I have not been able to charge my car using MBUX which was often what I turned to when the App is not working. My final option has always been to call the customer service folks at EA to get remote charging which has always been reliable even if time consuming. UNFORTUNATELY, THIS HAS ALSO NOT WORKED THIS WEEK. The car's charging port would begin to initialize and then appear as if charging and then just STOP. I tried two different EA charging stations and several chargers at these locations, all with EA customer service rep on the phone with me and nothing worked. I thankfully had enough charge to drive to local MB dealer to use their level 2 charger but may need to take back now to see if something is wrong with my car (no dashboard indicators showing any problems) and I was able to charge using level 2 charger at MB dealer.

Same here in Germany with an EQA. Ionity and the EnBW network and also the charging station at work, work very reliable. What I discovered, is that the RFID card works better than the app. In some cases (smaller charging locations), the charging stations seem to be offline. So only the RFID card works. Once I met a BMW i3, with the same problem. So the "problem" was not related to Mercedes. App won't work, but RFID card did instantly. So far I have not used the MBUX feature for charging. Most of the time it is useless, because you have to walk around the charging station to find out its number.

Charging EQB is disaster, our EQB has been at Service few times, and Mercedess Service claiming nothing wrong with it, Mercedess tried to get to $60 K car market competing with Id.4, Muche, and Ionique but really screwed up, I had owned 17 Mercedess and this will be my last, everything about Mercedess is going down the hill, Me Connect is a joke........ Good Luck with your EQB

EQS580 ‘22 chg card & connect me services NOT completing

I actually don’t know where to begin. The Mercedes connect is not finishing the activation for their 30 minutes of free charging it’s saying it’s registered but then it’s saying when I give the information the car is already defined and noting an error in the process…. but it’s asking me to define it my sales person and I were on with MERCEDES Me Connect support yesterday several times to NO success, I am also an owner of a Tesla model X at well everyone complains about the Tesla. I have to tell you the programming of it and computer skills are Way Beyond what MB is OFFERING. To put it simply well I’ve only had the EQ 580 for a few days. The car seems to be magnificent and Acceleration a bit slower than a Tesla. However, my complaints about the Tesla, were more in this category it seems Mercedes knows how to make a car but not how to coordinate the computer info necessary to make it a truly SMART E vehicle!!
I’m truly surprised that Mercedes put out an imperfect or incomplete product in this category

Any suggestions on Mercedes me getting to accept the complementary 30 minute charge card would be appreciated. We do have a Tesla charger at home that I have purchased an adapter for I used it once and it seems to work well but we are going on a trip and I want that ability to top it off if necessary till I get to my destination.

Thanx in Advance for any ideas, support or advise

Our EQB has never been able to charge via the me app or navigation system at any electrify america and have to call into EA every single time to remote charge. We've tried at over 15 different locations. Mercedes says it's EA issue and EA says it's a Mercedes issue. we've taken the vehicle in to check out an MB says there are is nothing wrong with the vehicle. Just got the car back yesterday and today i'm sitting at an EA while my wife is on the phone AGAIN with EA to remote start.

Did you ever get your money back? I bought a 2023 EQB 300 and it started having charging issues 2 months after I got the car and has continued on and off ever since. Mercedes initiated the Lemon Law process this past Dec. 8th, and I just received a denial notice today saying that, "In order to legally qualify for MBUSA to offer restitution or replacement, the subject vehicle must have defects covered by MBUSA!s written warranty which substantially impaired its use, value and/or safety which were not repaired after a reasonable number of attempts." The car has been in the MB shop several times for this issue and it's not resolved!

It is not the network, It is EQB. Mercedess blaming the networks but it is a total Lie..... My EQB is at the service for over a month and they cant fix it, they are offering me compensation to take the car, but I refuse to do it. Mercedess should have done their home works before releasing and alos they are holding releasing 2023 Models. How ever I have EQS450 and have no charging issue.
Shame on Mercedess..
