I just picked up my EQE SUV 350 4matic and had the charge point charger installed.
Installed a 60 amp circuit breaker, so the charger is pushing 48 amp. Car is charging at 8.4kw.
Seems that the reason i am not hitting the advertised 9.6kw rate is due to the electrician installing a 208v cable, rather than a 240v.

Don’t assume that the Chargepoint is delivering the full 48A. Call Chargepoint and see if they remotely down rated the amps on the Flex. There have been reports of them doing so for ‘safety reasons’. Once you’ve answered some questions about your install hardware, they can remotely switch it back to the full 48A continuous.
Not saying this is the reason, but worth checking on first.

interesting thank you for that. I’ll give ChargePoint a call.

I am based out of Toronto. Bought 2024 GLE 450e, same problem - max charge rate 7.6kW vs 9.6kW advertised. I filed ticket with corporate office.

I think our cars in canada are locked to 32amp

tuffcalc

Agreed. I also filed a ticket with corporate. Waiting on resolution.

I did a trouble shoot with ChargePoint. According to them, the 208v line installed line is hindering the full charge. So it does align with the 8.2/3kw the car is displaying. According to my electrician, local NYC, code is 208/220v. 240 is not an option I am told.

RomanK

did they get back to you? I got a follow up call from MB Canada to advise me that ticket is still open.

RomanK

did you get this resolved?

tuffcalc

nope.

@bytemaster0 would you be open to sharing your VIN by private message?

I have Mercedes Canada involved and they are looking for a US EQE vin that is confirmed charging at 9.6kw. They want to compare my VINs against that to see what the difference is, and why we are only charging at 7.6kw in Canada.

Would really appreciate it !

@tuffcalc , sent. Please keep in mind that mine is a sedan, but my dad's EQE SUV also charges at 9.6 kW and is US-spec.

tuffcalc

Thanks so much. I’ll send the sedan for now and see what they say. Really appreciate all your help !!

RomanK

let us know what you find out

i know bmw app you can set the charging rate lower or to the max. is there a function in the mercedes me app to set when charging to full power or lower it to 7.6kw

tuffcalc

After months of back and forth, the dealer states that Germany tells them vehicles in Canada are software limited to 32amp level 2 charging due to cold weather battery charging concerns. Apparently this is not a concern for US vehicles and their charge rate is 40amp @ level 2.

I think the Merc engineer who made this decision needs to give their head a shake considering that some US states are colder than many Canadian regions ... and oh, the Tesla I bought in 2012 charged at 80 amps on level 2!

In the US, almost all of the EQE SUV's competition charges at 11kw, so 9.6kw suggests Mercedes undersized their on-board charger hardware vs the competition. 7.4kw is just sad.
If temps are the excuse why not just regulate with a thermal sensor...

Cadillac Lyriq and GMC Hummer can do 19.2 kW (240V x 80A) which is a requirement for my next EV. I'll have to upgrade my residential service to accommodate the 100 AMP circuit for the charger though. Might as well buy a bigger house too while I'm at it I guess... maybe something with a three or four car garage.

I am from Laval (Montreal adjacent) and own a EQE500SUV, installed a 50A charger (max) and measured 247V at the charger input, put a 3/3 cable from the breaker box to the charger and installed a 70A breaker... I cannot get more than 7.6kW charging. how is it that I can file a ticket with MB Canada? I guess if enough of us complain, someone might eventually listen^ (there cant be that many EQESUV sold already though, but wont hurt to try)

@bernie.EQE50SUV I am away from my car and cannot test this, but try turning ECO mode off and setting max charge to 80%. It has been suggested the EQO is a limiting factor.
