EQE Home Charging (USA)
What is everyone doing for home charging? I considered sharing an existing NEMA 6-50 220V outlet in my garage that I use with Tesla Mobile Connector to charge my 2019 Model S. I saw that there are adapters available for the Tesla connector that might have been suitable, but it would have involved a lot of gymnastics in switching parking spots so the cable could reach, managing charging periods, etc.
I decided to go with a dedicated solution for EQE....had a new NEMA 14-50 outlet installed on opposite side of garage (closest to EQE parking spot and charge port). Found a JuiceBox 32 on sale ($200 off at WalMart). So far, looks like a good solution. Interested to hear what others are doing.

Splitvolt 24 AMP for NEMA 14-30 dryer outlet with a 26' cable was $299 with coupon and a Parkworld 14-30 Y-splitter was $63 at Home Depot. That gets me from 20% to 80% overnight so good enough for me. Got a NEMA 14-50 adapter for it too so can plug in just about anywhere. I think that's about as cheap as level 2 charging gets.

We've been using a ChargePoint Home Flex, have been very happy with it, and the metrics in the app are pretty solid and useful. Not the prettiest app, but quite functional. The cold-weather flexibility of the Home Flex cable seems to be excellent. I also really like that the adapter dock rotates so you don't have to aim it perfectly to put the adapter back into the dock.

i installed a Chargepoint Flex in my garage also. Extremely happy with the setup. The app has equally been great with lots of tracking charge features. My only issue is the app does not allow you to decrease the max amp throughput after install if you want to decrease the charge rate you have to reinstall the charger in the app and lose your past charging history ( MB Mbux has no feature to reduce charger rate). During a hurricane if on a portable generator I see a meed for reducing amps

Charger rate - Chargepoint Home Flex
app previously allowed you to change charging rate after install. Presently you can only select the charge rate when first installing the charger in the app. Once installed and activated there is no option to change charging rate (eg lower for a portable generator due lost power during a hurricane)

Potentially; however, I think they may be keen to prevent housefires and liability claims, which is why they put all of those functions in an installer app. The possibility of an unreliable connection or even a fire is too high for those users who may want to try to squeeze more power out of their EVSE without knowing what it means for the supply cable.

Ok I get that as I have considered buying a Chargepoint but haven't because I only have 50 amps service to my garage and am not sure I can trust the software derate (in my case to 32 amps).

I believe the EVSE doesn't limit the charge at all, it just has a relay that kicks on and off. However, with its communications electronics, it informs the car's onboard charger the max current that can be consumed during bulk charge.

ok thanks that's interesting. Didn't know that. Sounds like not something I would or should rely on. The max I should pull is 32 amps for the EV to leave headroom for other draws so I will stick with a 32 amp charger. Would like find a hardwired one.

Other brands allow you to that.
ChargePoint seems to be very popular here, but it does not work for me. Apart from this ridiculous limitation, it also does not have Power Sharing.
Power Sharing is a must-have for me as it allows me to have a second EVSE installed without expensive rewiring to the panel.
I am considering WallBox Pulsar Plus which has Power Sharing, and also current adjustment through the App: https://support.wallbox.com/na/knowl...rging-current/

In any case, for my needs, the very flexible cable, the angle-independent dock, and the cable management of the ChargePoint Home Flex work great for me - not to mention it already integrates charge data for MB's charge program as well, so I get to see DCFC and home charging data all in one place.

Just as an FYI from my experience in buying an Autel 50 amp charger off of amazon... The charger was hooked up to a 60amp circuit which should give it 48 amps and about 11 kwhs charging. When I only got 9.6 kwhs I thought something was wrong with the charger. Took me some googling, but found the EQE (SUV) will only accept up to 9.6 kwhs from a level 2 charger. So no fault in the electrical/charger, just limited by the car. I'd recommend the charger with the separate holster. Good luck!

To avoid (most my own) confusion I always think of volts as being "pushed" and amps as being "pulled". Supplying too much voltage will fry electronic devices but they only draw the amps they need.
