Welp, I just ordered one of these:

Just had the electrician out for the estimate on the unrelated upcoming panel work and thought I might as well get this in for when they do their work.

FWIW for my Fusion Energi I bought a JuiceBox - original generation, as in didn't even have WiFi or anything, so old the company doesn't even admit it existed any more - and it's still plugging away after 7 years or so. Just wanted to get something a bit smarter for the second charging port. (I haven't decided yet if I'm keeping the Fusion - so I might need two chargers in the garage. Yes, I know I could just have one and move the cable or cars or whatever, but in for a penny, in for a jillion dollars.) I believe it actually supports 48A if you hardwire it, but given that the Fusion can't even do 40A, it never seemed worth the trouble ;)

I have that same 60a Juicebox but its packaged in a battery looking thing.

Yeah I have 3 EVSE's (well 4 if you count the one that comes with the car): The Bosch one is my original one, the Clipper Creek I keep in the car for campground use, and the JuiceBox I won with my blog. Don't think I'll be pony'ing up for the Ford one--last thing I need is another EVSE!

The JuiceBox's cable is only about 5ft long so I can only use it when I park next to them. When the car is out in the driveway I use the Bosch charger since its cable is 20ft.

The advantage of having a Nema 14-50 or Nema 6-50 plug at the end of the cable is that you can move them around. :)

that's actually a newer version than mine - that version they still admit exists, from what I can see on their web site ;) Mine came with a rather long car-side cord (25 ft maybe?), which I admit I thought about just running up to the ceiling and over to the other side of the garage. We'll see what I end up doing ultimately when the electrician comes to do the work.

I actually have 3 types: The wall plug is the 6-30. The ClipperCreek came with a L6-30 on it so I put an L6-30 on the JuiceBox (and don't run it more than about 26 amps).

I also have an adapter for the ClipperCreek from the L6-30 to the 14-50 a campground uses (the ClipperCreek is an LCS-20P so it won't even get close to 30 amps).

You'll note that none of these are the "fastest" you can get with an EVSE. The MME will be the first BEV that I can't get to a full charge overnight (say from 10pm - 7am) if its completely empty (which will be a rare occrance anyway).

Even on the Bolt with its 60kWh of battery I can completely charge up overnight at 26 amps.

That OpenEVSE is a really nice unit and with the WiFi control, I can throttle it down to only 10 Amps or so that on a cloudy day when my solar output is low, I don't pay for grid power --- just charge longer. And it's easy to set how many KWH’s you want to add or by time.

All from either your smartphone or computer.

I put mine together in the kit version a few years ago --- fun project if you have a pretty good electronics background.

One thing to consider with any EVSE, is that when it is plugged in there is 240V power connected to the Main Board EVSV controller at all times whether charging or not.
I had a lightning hit do an over-voltage on the controller board --- was an simple replacement $80 part and about ½ hr fix.

If you don’t have a whole house surge protector, I would suggest a surge protector on the 240V feed line, as that unit is always “hot” when plugged in.

I thought of that, but this felt just past my skillset. It's a lot of power - I'm pretty happy when I can avoid burning down my house playing with a Raspberry Pi fed by microUSB ;)

hmm. that's an interesting thought. I'll have to research that some. I've lived without until now but again having work done so...

Ahh --- the amazing Raspberry Pi's, I use those to control both my electric hot water heater and my pool pump / heat pump with python programs. All from a $25 - $40 board.

Update: it arrived today. Swapped it in place of the existing JuiceBox, and it came up on the WiFi fine. Seems to be charging the Fusion Energi at 13.42 A. I see it has MQTT so I think when I have some free time (maybe tonight!), I'm going to see what I can do about feeding the data into an Azure IoT Hub and Power BI... :) (There is an OpenEVSE dashboard site, but I think I'd like to use this as an excuse to implement some stuff instead ;))
