What $70K ICE car would you have gotten ?

[DucRider]

fastwheels,

Thanks for all that you forwarded. I’ll bet those 800 miles were great fun, but it must have been gnawing at you while waiting to get rolling again this year.

Thanks again for all, especially the update. It gives me some hope we’ll eventually get the full BEV ElectriVette one day.

Not a GM product, and you can buy 10 Rivians for the price of one, but:

One of the drivetrain engineers has his shop just down the road from you, and the inverters/controllers are also from a Portland area company.

Load sharing is clearly still being advertised as a feature of Tesla's Gen 3 charger.

Defintiely but that's not the same as putting 2 chargers on the same circuit. And load sharing between Gen3 HPWC is not available now. It is coming at some future time measured on the ELon time scale.

I just looked at the Gen 3 installation manual. It does say that you need 1 breaker / charger, but one layout suggested in manual is a subpanel. So I could add a small subpanel where the existing charging circuit terminates and then run both chargers off of that subpanel. When only one car was charging, it would be able to take in 100% of the subpanel's load and if both cars are charging, it would automatically cut the power to each in half until the first car finishes and then 100% of the power can go to the second car.

Yes, you could do that but you would have to find Gen 2 HPWC somewhere and I don't think Tesla has extended that one time offer. And you would have to run the control cable conduit between them. I don't really see the advantage to doing that except that you can do this today with G2's but you cannot with G3's because the firmware isn't there yet. One thing that is nice about the 3's is that the cable is thiner (because they don't do more than 48A which is the most a Tesla or Rivian will take) and therefore a little easier to manage.

However the manual does contain a note about how the feature is coming via a future OTA update. I am not sure if that is outdated and the feature has now been implemented, or if that is still coming "soon".

I haven't checked in two months but as of late June, not available.

Note that when the sharing firmware does become available that you will be able to share between two Rivians or two Teslas or one of each and the same will be true of any other EVSE that allows sharing.

Clipper Creek, Chargepoint, EnelX and others all have EVSEs that allow multiple units to be installed on a single circuit.
The 2104 NEC was modified to allow these types of installations (prior to that it specified each EVSE must be on a dedicated circuit).

Most (all?) do not do true dynamic load sharing on their homeowner targeted products, but instead divide the available circuit capacity equally among all active EVSEs on the circuit.

Manufacturers are also starting to offer multi head EVSEs within a single box instead of two seperate units.

We had family visiting in EVs often enough that - even though we currently only have one EV - we installed a second charger to help them.

Wallbox Pulsar Plus.

Certainly shares DNA with their commercial offerings but is definitely consumer oriented.

100% truly dynamic load sharing of one circuit (as long as you network them with a dedicated CAT5E, which we did)

We just leave an extra J1772 adapter on the Tesla side, and the other one is charging a native J1772 car most weekends.

48A to the Tesla when its alone, 24A to each when you plug in the second car, and right back up to 48A if the second car finishes charging.

We love it.

Truly dynamic load sharing will look at the actual draw of each vehicle as it is charging and allocate more to the second plug if capacity is available.

If a car drawing 16A was charging, the remaining 32A would go to the 2nd vehicle instead of an arbitrary 50% to each.

For the price I would grab a SQ7 but in reality I would cut my loses and spend less to get something that was suitable.

Yes, that's what it does...? It's a smart, dynamically load balancing system.

The numbers I gave were what we typically see when we're not "playing with it" because each car is (obviously these days) capable of at least 24A charging.

So when both are plugged in, both are capable of taking at least 50% of our 48A circuit, so that's what both get.

You can dynamically change the split in the wallbox app (if you want) with a minimum-per-charger defaulting to 6A. We played with this and it works.

But after initial configuration you certainly don't need the app or any sort of internet connection at all. The chargers talk over a simple CAN Bus network.

If one of the cars starts charging more slowly than its allotment, the chargers gives the rest of the circuit to the other car. We played with this, too, by telling the Tesla to charge at only 18A and watched the other car creep up to 30A over a few seconds.

The system is great.

It supports up to 25 chargers, sharing much larger than typical circuits, and needs no Internet connection.
In a case where the number of plugged-in cars would exceed circuit capacity even at the minimum charging allotment, it will even queue up the new cars on the circuit to charge them after earlier cars finish.

Those features are, of course, handed down from the commercial installations that came before the home unit.

Thanks for clarifying that Wallbox supports true dynamic. Most use the arbitrary "divide by the number of vehicles actively charging" method.

Should indeed read 2014 NEC. Even after your comment I saw what I expected to see and not what was actually written...

The funny thing is I saw 2014 when I read it as well (twice), wasn't until he said time travel that I saw the transposed digits (third time reading it)...

That is why I could never be a proof reader....

Navigator or Yukon Denali. Thought the PHEV Aviator would have been my alternative, but I have a gas one on loan from a dealer as a placeholder for my R1S and I am dissapointed.

I got all excited for a moment, then disappointment set in when I got to wallbox's website and couldn't find any products with Tesla plugs on them. Re-reading your post, you are using the adapter to charge your Tesla which is not something I would be willing to do on a daily basis.
