Level 2 home charging
What kwh are you guys getting charging at home for the EQS? My Homeflex is set to 32A @ 7.6 kwh, that's about 23 miles per hour and I want to bump it up to 48A to charge quicker. Would charging at 48A be a problem for the EQS? My current wiring is 6/3 with 40A breaker. I know I need new 60A breaker, but I just want to make sure the EQS can handle it. I been charging at home for the past 2 months, tired of dealing with out of service EA stations and the long waiting times.

Depending on how the EQS views the charging battery temperature it will automatically choke down to the appropriate charging rate. I have used a 60amp breaker for over a year and all is well.
I do not know your experience with wiring level. If you are not wiring directly to the electrical box do not buy the cheap under $20 220v plug off of Amazon etc. They can eventually heat up and melt. Spend more bucks on the American Hubbell Brand.

It'll only draw the amps it can physically take. It's voltage spikes that'll kill your car and lvl2 EVSEs are really just overly complicated surge suppressors.
They really should just put a NEMA plug on the side of my EV so I can use a plain ole extension cord and end all this madness, IMVHO.

Pretty sure the max rate the 2023 EQS SUV will accept is 9.6 kw on a 240 volt ac circuit. That equates to a 50 amp panel breaker and a 40 amp charge rate on your EVSE..

I'm going to try to replace the breaker this weekend. There only 1 EA station within a 7 miles radius and most of the time 2 out of 4 are out of services. Mercedes gives you 2 years free charging but good luck trying to use it LOL
thanks everyone!
thanks everyone!

Fookin' electrical jargon is almost as bad as financial jargon. Ground doesn't actually have to be grounded it's just a second path of lesser resistance and volts is really just the difference in electrical potential between what's providing the juice and what's sucking on it. I guess obfuscating concepts that aren't really that difficult to comprehend gives some people job security.

Waiting time can take up to 2 hours. I just charged at home now. I have a 7 kwh solar system on the roof so it doesn't cost me anything to charge the EV. it just takes a little long that all. I don't know why i feel like i have to public charge it. Maybe because it the free 2 years thing.

I've got a 50A breaker and am getting 7.3kw. I also can't rely on the EA chargers; they're always packed and I don't have time to wait around for one to free up.

There were reports of Chargepoint derating the amps delivered because some owners/users had configured the Flex incorrectly. Call them up and ask them if that happened to you. Once you explain you have a 50 amp circuit and that the hardware is adequate for 40 amps continuous, they can up-rate the Flex via the web.

The max you should do if plugging into a nema plug is 50a (actual 40a) = 9.6kwh. the EQS is not capable of more in the US anyway, but if you did have an EV that can charge faster than 9.6kwh, you can not just up the breaker to 60a. The nema plug itself is max rated to 50a so you have to go hardwired if you want to use a 60a breaker.
Not being hardwired with a 60a breaker (i.e max 48a (11.5kwh)) is dangerous. And on the chargepoint that is capped via software setup. If I remember during setup it asks you if you are hardwired or plugged in and sets the max accordingly.
I believe the reason that MB capped the EQS at 9.6kwh in the US maybe due to this reason. For example I have a friend that got a Mach-e which has max 11.5 charge rate. He called a non licensed electrician to install a nema plug with a 60a breaker until I told him to turn down the charger to max 50a.
