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.

My purchased new 450e came with a 120v charging cable only. I use the cable when at our vacation home.

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).

6600/240 = 27.5 amps. This is 91.7 % of 30, and ... is not good. The National Electric Code says you should not exceed 80% for continuous load.

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.

Thanks for the heads up. I did not know that, and will go back after the dealer.
