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?

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?
It is displaying 5.2kW, which I dont think is correct, the charger is capable of 9.6kW.
Sorry, that was a typo it was supposed to say 5.9kW. I have tried different charging stations and it’s the same result. Is there any setting I can change or a factory setting that can be applied? According to my calculations, it’s is currently take 2-3 hrs longer at a level 2 charger. And home charger even longer.
The charger is at work, it works and pulls properly for other cars. My initial thoughts were similar it is the charger, but we saw the charger was getting proper 30A.
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.
No, this is what I have been looking for, how did you manually set the amperage setting in the app? The charger I use does not have an app. Is there a setting in the car to set general Level 2 chargers to pull more amps? Also, I vaguely remember when I first setup charging on my Mercedes App it asked me for fast charging or slow charging, did you have this option on the Mercedes app?
