Going to install 240V 50A outlet for my model 3, will it work for my Prime as well?

Don't waste your money on the Turbocord; it's slow and expensive for the price. I would get a 40 Amp EVSE and use a j1772 to Tesla adapter to charge your Tesla. The Prime will limit the the charging current to less than 16A on a 50A breaker. Do you know if the j1772 adapter comes with the model 3?

 

You might consider a Tesla distribution EVSE with an adapter to J1772.

It may be costlier to take this path, but if they already have a Tesla EVSE, then this is the only choice. I see it costs $240 for the adapter to go from Tesla to J1772. I'm not a Tesla owner but I think an adapter to go from J1772 to Tesla comes with the car. A Tesla EVSE costs $500 + $240 adapter = $740. A J1772 40A EVSE starts at around $400. Plus you can pay more for features like Wifi.

As an example of a 40 Amp charger compatible with the Prime*, and an adapter for Tesla.

* While the Tesla will charge at 40 Amps, the Prime is limited to 16 Amps no matter how large the EVSE is.

 

For your Model 3 I would recommend having the electrician install 60 amp service. This should provide the long range Model 3 with its max of 11.5 kW.

As for your Prime, I think 3.3 kW is the max there.

If you think you will ever get another Tesla someday and want to get the Tesla wall connector, there may be some wisdom in running 100 amp service to your garage since Tesla wall connectors can share a circuit intelligently. Will let @hill chime in here since he was the one who educated me on all this.

 

that's it? 11kW? That's odd, I wonder if they did that to keep the cost of the on-board charger down, because the X will do up to (either 48 or) 72 amp, & iirc the Model S's are capable of (either 40 or) 80 amps.
.

 

I believe that is the max with the HPWC.
The max charge with the UMC that comes with the car (with a J1772 adapter) is 32A or about 7kW.

Since the UMC and the J1772 adapter come with the Model 3, I would recommend the OP install a 40A or 50A outlet, use the free UMC and spend the money on the adapter for the Prime. Alternatively, if it has been working alright, continue charging the Prime with the 110V outlet.

 

Yep, you are right. Looks like 7.7kW for the UMC.

 

If you are going down the road of plug-ins now and expect to own another couple vehicles in your lifetime, it would make sense to size the outlet for 100A. Even if you only use a fraction of that now, you don't have to upgrade the breaker, the wiring, the conduit, the disconnect, etc. Just the EVSE. Having way oversized wire is good in every way except slightly more expensive. If you're paying someone do to this, their time is the majority of the cost.

 

I’d add, have a 100A breaker and two 50A outlets, one near each car.
That is if you want to future proof your home.
If you aren’t planning to be there long, it is a toss up.

 

I'm putting in 2 100A panels on opposite sides of the garage. Would allow for 2 indoor EVSEs or 2 outdoor EVSEs. The panels only have a few spaces but have their own 100A main breaker and I could put in multiple breakers to outlets or hardwired EVSEs. As of now they'll stay empty with just the main breaker as the Leaf is happy charging at L1.

 

We will be moving in less than a year. In my new garage I definitely plan on putting 100A service in. If the panel is a long ways away from the garage I may consider doing more than that just to save the electrician from coming back in 3-5 years.

I would love to future proof it for a possible Tesla Pickup which may have a 150-200kWh pack.

 

to answer the OP's question, yes, charging 240v instead of 120v will be more than twice as fast.
That said, if you use a Tesla Appliance, whether the HPWC or the car's UMC (comes w/the car) - those appliances will not allow your car to charge faster, even though the units can deliver more power than your plugin Prius can receive.
Regardless of which Tesla Appliance you use, yes, you can use either to charge through the aftermarket Tesla to J plug adapter, which looks like this;

Someone earlier said the model 3 could not pull this much, but here's a shot of the screen showing its capable of receiving 48 amps from a 240v source;


That's a tad more than 11.5kW's. If you really need the full 48amps that the model 3 can receive, that would require the hpwc, rather than the portable unit that comes with the car.
If you get a regular J plug charger, any one of several manufacturers, they typically Max at 40 amps. So you would only be losing a little less than 2KW capabillity over the Tesla hpwc (which, btw, can easily be reconfigured for 80amps - for some future use)
.

 

unless he's an electricity skin flint like me - 120v being less efficient - us skin flints try & go no lower than 208v.

Yes . . . . and apparently (a company that I've been down to, in San Diego - great people) - there's an aftermarket Tesla high power wall charger manufacturer that sells on ebay ( maybe their website to?).
Tesla J-Wall 80 - Made by QuickChargePower, J1772 Charging Station - was HPWC | eBay
Hope that link works ....
Just over $300 plus shipping. If a prospective buyer keeps a Vigilant eye on eBay, every once in awhile a Canadian guy, including shipping, will sell you the OEM high power unit (24' cable) for an even $300. So even with the $240 tesla to J1772 adapter, you can still walk away for under $550 & be able to charge a tesla up to 80 amps (supported on board charger only) - providing you have an available 100 amp breaker.
and - iirc, the J1772 adapter is good up to 40 amps - provided your J1772 car runs that high.

has Tesla derated their UMC's to 32 amps?? Our older one~



runs at 40amps


.

 

Yes, the new ones max at 32A.
Frankly, the difference for people charging overnight is minimal. For those for which the charge rate is critical (e.g. small window of super off peak charging) a HPWC is a better solution.
