Mercedes Wallbox Charger
Does anyone know who makes the Mercedes Benz Wallbox Charger? The dealer said that they are giving away this charger if you buy a vehicle between now and the end of the year. There isn't much information available online. I was just curious if it might be made by another manufacturer or if anyone knows where I can get info on it.

The 110 volt version was included with our EQS SUV and it charges at 1.3kw. As far as I know it has no WIFI or Bluetooth so no App access. I believe there is a 220 Volt version as well that I have no experience with but my guess is it is pretty basic as well.

Thanks, he said that it is the 220v version that would need to be installed by an electrician. To be honest, I would prefer the 110V charger for free for emergencies,

That Mercedes Benz Wallbox Supply unit looks good with lots of features and looks like 32 Amps of power. If it is made by Wallbox for MB then that is positive as Wallbox gets a lot of great reviews. Yes you will be able to hardwire it if you like.
Some more info.

Thanks, between the two documents provided in this thread, I think I have enough info. It isn't going to change my mind about buying the vehicle (I was planning to buy it even without the free charger), but it is a nice bonus.
The RFID card is interesting. I'm not sure that I would have a need for it since the charger will be in my private garage, but I guess if someone installed the charger in a shared space, it could be handy.

I'm just curious if you ordered yours through the web site, or if the dealer gave it to you directly?

The dealer provided me with the link to request my free wall box, but the site keeps telling me that it is an invalid VIN. I opened a ticket with the company that processes the requests last week, but haven't heard anything yet (they told me 24-48 hours, but it has been way longer than that). I will call them again in a couple of days. I haven't decided if I will sell it or possibly use it. More than likely, I will stick with the Emporia charger I already have installed.

Must be nice we did not even get the 110v one ROFL with neither our S or Es I was going to get the wall box unit but I found a better deal with the chargepoint home flex unit. Has wifi, 50 amp, the usual app and so far it works great.

EQE 350
I just purchased an EQE today and will be receiving a wall box for free. Are these wall boxes able to hardwired and connected to a 24 AMP line? I already have a 14-30 outlet in the garage. I am ok with slower charging speed.

The unit is made by Webasto, and depending on when you receive it you might have the original branding or one with Mercedes branding. It can be used for 1.2 kW charging with the 120V 15A plug adapter or 9.6 kW with the 240V 50A plug adaptor. Electrical code limits the sustained load on an outlet to 80% of the rated capacity, hence the somewhat lower power ratings than you might otherwise expect. (Your circuit breakers will enforce the 80% limit if they are working correctly.)
I have my car set to charge during the low cost periods for the electrical tariff and find that I get roughly 1% of battery capacity per hour on the 120V outlet in my garage, or about 15% per day per schedule. That turns out to be plenty for my normal driving, so I shelved plans for a 240V outlet. On the rare occasions that I use more battery, DC fast charging has been mostly satisfactory. (EA basically sucks, but I usually can find a working charger when I need to.)

Does it appear any different in the MB battery transaction interface? Does it support multiple boxes on the same circuit for peering? We're sharing one ChargePoint Home Flex, and it shows all transactions as public charging. Does the MB Wallbox show up on ChargePoint app? I'm guessing not, but would be cool if it did.

No, charging on the wallbox does not show up as transactions in the Mercedes Me app. I have only one box so I have no information about how multiple boxes might work together, but I kind of doubt it as the box seems to be a pretty simple switch. In my case, I already have my solar system communicating over the power lines, so I am not keen on yet another power line communication taking place; it was a pain finding an outlet where the solar communication system worked properly.

Wallbox EVSEs will load balance based on whether one or both chargers are running. Are you using micro inverters? We have string, so no communication is necessary, though of course you have other issues such as string efficiency concerns with partial shading and differences in panel performance.

I think I should clarify what the Wallbox does, as it is a rather simple device. It basically does the following in order:
1. Signal that AC power is available to the vehicle.
2. Passively signal that the cable is plugged in (detected from the vehicle).
3. Detects the charging status of the vehicle (present, ready/charge, ventilation required {some batteries may only be charge in a ventilated space}) or disconnect.
4. Informs the vehicle of the charging current available.
If a vehicle is connected and ready to charge then current will supplied on the charge leads until the vehicle signals present. Pressing the latch to release the cable will cause the car to signal present to stop the charge session.
Note that there is no voltage signaling; the inverter in the car will handle 120/240V and limit the current drawn to the limit specified by the wall box.
The plug adapter used will indicate to the wall box the max current to be drawn - if you use the 120V adapter, the box will signal 12A maximum, the 240V adaptor will signal 42A as the plug can only be inserted into a 50A outlet. (Presumably there are other pigtails for other sockets that will signal different current limits.)
In the end, the wall box is a fancy switch.

Great summary, only thing is that I believe the pigtails are all passive - the current limits need to be set by the user when the wallbox is installed.

I think the pigtails are keyed so the wallbox knows which one is present. I would not trust the consumer with setting the correct current limit - too much risk they would get it wrong or deliberately set it too high to "charge faster." That way leads to burned out sockets and wiring or worse if the breaker does not open in time. The liability for the wall box manufacturer is not worth it.
l don't really trust builders either - I found 14 gauge wire on 20A circuits in my house, and there are some other electrical funnies to make me believe the builder paid off the inspectors to pass non-compliant wiring.
You can be sure I checked all the wiring and outlets between the circuit breaker and the 120V outlet I plug my charger into before I tried charging the first time (I wanted to be sure the wires were on the screws and not stabbed in the back of the outlets), and I monitored the temperatures every 15 minutes for the first five hours of charging to be sure nothing was having a problem. In theory, a standard outlet can take 15A loads for a few minutes and 12A continuously, but I would definitely check.

MB EQE 350 V4
MN Wallbox Installation Experience
I am a new owner of 2023 EQE 350 V4. Got a free wallbox from MB. It arrived in a few weeks. I hardwired it by running 6/2 cable with 50 Amp beaker. Installed inside the garage. Activation was relatively smooth. It works.
I am not a professional electrician, but expressed DIYer. Happy to advise if anyone has any questions.

Question regarding firmware updates. There's new update 5.14.7 available through the Me Connect app, however the Wallbox hasn't been updated. I have auto-update enable but still nothing. Anyone have experience with Wallbox updates? Thanks!
