450e Charging device
Charging device.
This is the charging device that came with my CPO car. Do you folks have one of these or an MB branded one? It’s showing 7.3 kw with a standard 240 outlet. The manual shows an MB branded one.
Thanks.

I have an L2 charger installed in my home parking spot. It's charge rate is set to 6.6kw because it is fed by a 30A breaker.

Mine looks the same. I plug into a 120V/15Amp outlet and the car reports 1.1 to 1.2 kw, so it is pulling about 10 amps. The other pigtail that came with the charger is for a NEMA 14-50 socket (240V, 50amp). [I didn't look at the pigtail, but the Amazon product page states this]
Your 7.3kw means it is pulling 30amps, while the socket and wiring would support 40amps. Noted elsewhere (perhaps on this forum), the charger doesn't know the amperage of the circuit and pulling the minimum of the common options is a safety measure.
Edit: just saw the previous post from parato, which casts some doubt on my last sentence as I can believe that 240V/30amp residential circuits are common. This would lead to a draw of 5760 volt-amps (240*30*0.8).

You are correct. My typo. The breaker is 40A. We have a 3phase 208/120v supply. The charger is set to 32A. 32 is 80% of 40. 32x208=-6.6Kw.

someone ripped you off. The car should have come with 2 pigtails. The dealer has figured out a way to make a few extra bucks.

I just tried a Mustart charger on my 50A wall socket. It is rated at 40A. I am seeing a higher charge rate compared to the factory charger, 7.6kw vs 9.6kw. My understanding is the GLE450e can support the 9.6kw charging. Am I wrong? Also the wiring on the Mustart is much thicker. Now the difference in charging times doesn't matter to me. Is it better to charge at the 7.6kw or the higher 9.6kw? Some say the DC charging can degrade the battery quicker. would that be the same on 7.6 vs 9.6?

What time frame are you all seeing for a full charge from zero or close to it using the charger the car came with but with 220 with a 40 breaker? I’m currently using 110 and it takes more than 24 hrs. So I’m seriously considering having the 220 installed with an 40 breaker and trying to figure out if to keep the same charger or get a new one. Thanks for any input.

In Canada I was supplied a 120V cable only. After reading here that a 120/240(208)V cable is available I went back to my dealer and was told that MB has started supplying that cable in 2024 for the EQ series but not the Plug In Hybrid and it would be a $750 option. Looks like I need to speak with MB directly.

In the condo building residential outlets are 120v.
In the parking garage when we installed level 2 chargers they were connected to a 208v supply.
By the way, many multi unit buildings don't have sufficient capacity to provide lavel 2 charging at every parking stall.
To address this we installed chargers that are networked together and ensure the total charging load does not exceed the buildings rated supply. When the demand (too many cars plugged in at once) exceeds demand the charge rate is reduced to stay within the supply limit. When some car finish charging the rate is then dynamically increased.
