Yesterday we got rid of the F250 that we no longer needed and replaced it with a 2023 Nissan Ariya Engage+ for the wife.

Will have to charge on 120v outlet for the time being, same as my Mach E, until we do an electrical upgrade which is planned in the near future. At that time a dedicated 50amp outlet will be installed. I currently own a GrizzlE smart charger that I have never been able to get the smart function to work on...........charger works fine tho

What would you suggest for a dual charger?
My ChargePoint ain’t so “smart” either so I just use it as a “dumb” charge station as do many others. As long as Ford Pass is working I can set times and % just fine. We will be getting a second EV and use the same charger on staggered days.

BTW it's really nice having an EVSE for each car. Plug in when you get home and you don't have to think about it. Good habit to get into.

The Tesla Gen 3 Wall connector will do load sharing on a single circuit. You can plug both cars in and it will balance the load as the cars need it. Other EVSEs also have this feature. I have had good luck with the Tesla units. Have your electrician wire up a 60a circuit and a hardwired Tesla unit can charge at 48amps (11.5kW).
Yeah, but I’d be feeding the Muskrat. Don’t feed the Muskrat.

Depends on what your realistic needs and uses are.

Upgrading your service and panel to 200A and running a 100A line to the garage will be very expensive. Especially if the garage is not next to the panel.


Otherwise if you want a setup you don’t have to think about, you can get something like the Grizzl-E Duo or two separate chargers that can power share.
So far the quote looks like about $6000 for the upgrade, give or take. Electric comes to the house from a pole mounted transformer on our side of the street right in front of the house, so short aerial run. Breaker box is actually mounted outside the house. (weird to some folks, but common in TN and KY) Garage is detached and we enter via the alley. It currently has an overhead to supply the 20amps now. That will be upgraded and a sub panel installed in the garage

I’m considering the Grizzle E dual on Amazon down the line. Wife and I both have a commute and I’m too forgetful to remember to swap the cord before I go to bed. 1st world problems for sure but we’ll always be a 2 or more EV household so a nice convenience. I looked at Clipper creek but yikes are they proud of their hardware!
There are known compatibility problems with the Grizzl-E duo and the Mach-E (search the forum). It will cause charge faults and/or charging to cycle on and off endlessly. The signaling when two EVs are connected is not done to J1772 standards or in a predictable way which causes issues, I'm not sure if United Chargers cares enough to fix it (they will want to blame your car).

I was not aware. Thanks for the heads up

We have a Grizzle Duo and it works great. We have a Mach e, Kia EV 9 and Tesla model 3 and we have never had a problem. We are going on 3 years with the charger.

ChargePoint units "smart" features are really only good for access control and then seeing what the charger output is.

Most of the best EVSEs are dumb or pretty close to it. Tesla 3rd-gen are mostly dumb and first two generations were totally dumb.

Relative to this thread, I recently switched to a Grizzl-e Duo so we can charge both the Lightning and Mach-E. I wish they offered a Duo unit that could utilize more than a 50A circuit and it would be nice if it had some smart features or ability to configure load balancing. But it will do just fine for our needs. They were supposedly working on an 80A version of their Duo charger, but I don't know how true that is or where I heard/read it. Grizzl-e chargers are well made though.

I have a Grizzl-E currently. You aren't having any issues with your Duo?

My wife and I just share one charger. Never any problems. Usually charge one in the evening after both home, then switch before bed.
This is what my roommate and I do, but we often both charge to 100% or close as we’re currently in the rideshare life. I plan on installing dual charging at some point but that requires construction in addition to electrical

Clipper Creek (now Enphase) makes dual-chargers. It’s one EVSE with two charging cords and it shares the load. If only one car is charging then it works like a normal charger. If a 2nd car connects to start charging it divides the load in half.

It’s NOT cheap though. They come in different ratings (40, 50, 60, & 80 amps — though not sure if they still offer all those varieties). https://enphase.com/store/ev-chargers/clippercreek-hcs-d50p-dual-ev-charger-nema-14-50-plug-40

EnelX Juicebox (now defunct) used to have a smart load-sharing via WiFi. Instead of a single EVSE with two charging cords … you would end up buying two separate smart chargers — but they “talk” to each other via WiFi to negotiate if they can use all of the power (when only one is charging) vs. split the power (when both are needed).

It would have been nice for that WiFi feature to be an industry standard so that any two smart (wifi enabled) chargers — even if not the same brand — could be able to do that.

I have two chargers in my garage but honestly … mostly one car will have been used heavily and need a charge and the other was only lightly used and doesn’t actually “need” a charge. It’s not common that both cars were heavily used and both need a big charge (although it does happen maybe a few times per year.)

I agree with the first response. If you don’t know that you need to charge two vehicles at once, why spend the money on it.

Second, do you need to have a dual charger instead of two separate chargers?

The only reason we have two L2 chargers is because the Lightning came with one “for free” and I had load space after an upgrade on our service entrance for a different project.

I have two Autel units and can set them up to load share over wifi. One is hardwired on a 60A circuit, the other one plugs into a 50A outlet.

That price for a service upgrade plus feeder and subpanel seems reasonable.
