EQE SUV only charging at 32Amp, 7.4kw ???!?
All literature says it is 40amp, 9.6KW.
Is this happening to everyone else? If this is the case, Mercedes advertising is obviously wrong (false) - and I can't believe they are limiting AC charging to 32Amp on such a huge battery.
Brutal!




Quick internet search shows that in North America Mercedes will charge at 9.6kw if you are on 3 phase power (which by the way, pretty much nobody is). Otherwise limited to 7.4kw.
Lots of wrong information about charging this thing. I wish Mercedes would be more transparent. That’s probably by design because it is so much slower than everyone else.








I’ll try a Tesla wall box tonight at my sisters house and see what’s up.

I noticed the eqe I purchased is listed by the dealer as “pre august production”. I wonder if there was a change after that date?
… or maybe there is something in MBUX that’s limiting it to 32amp? I’ll have another look tonight.
Charging spec of the Canadian EQE SUV is 32amp.
On single phase the max KW would be 7.6kw? Maybe this is a Canadian thing ?




Charger/EVSE boxes are inherently very dumb boxes. They are programmed to emit a pulse-width-modulated signal to the AC charger on the car indicating what charge rate is available. That availability is set at installation time, and is generally not configurable unless it's reinitialized from the beginning. If the car is detecting any issues with that PWM signal, it will de-rate its charge to the next lower level, or refuse to charge entirely. Same with voltage sag and a number of other conditions. Definitely try another EVSE. It seems to be hard to find a 9.6kW EVSE outside of a home though - most public L2s are 6.4 kW, so it may be tricky to find one.
I purchased a cheap portable L2 EVSE in addition to my ChargePoint Flex Home, they can be handy and can serve as a separate reference in case something's odd with your original EVSE.




That screenshot is a head-scratcher, 240V@32A is definitely not 9.6 kW! Someone made a mistake in entry. Check with your dealer?

The screenshot above is the same on the Meec US website.
Interested to see if anyone else is seeing the same.
9.6kw requires 3 phase 240v. Very weird spec.
Are you sure your power is 1phase 240v?




I was trying to figure out if it was something wrong with our Wallbox since it charges fine at 9kW with the Etron and XC40 recharge.

More annoying, I purchased the Pinnacle Package for $10k to get the Adaptive Highbeam Assist Plus lights (the Matrix lights), and they are not activated ... so I have two issues to deal with.




Let's see what the dealer says. That's two major options (the other being 9.6kW charging) missing from this vehicle yet advertised as such. Nice
81B Single-phase AC charging function (6 kW-9.6 kW)
?
thank you !

I've asked Sam (the overseas coder who can enable matrix lights in Canada/USA) to see if it is a software issue. Hopefully he finds out.
