At Home Charging Station for Model X

At Home Charging Station for Model X


In anticipation of Model X purchase I put in a 220v outlet in my Garage, with round twist plug.

I was wondering if any of the current Tesla owners of S have similar outlets or using 110 or something different?

I all appreciate any insight.

Thank you.

Same charger used for Model S will work for Model X.

You should not need more than 11kW for overnight charges. I set up 3x20A, 230V.

Considering the cost of the car, I just went with the Tesla HPWC, since I had to upgrade the wiring in my garage anyway. Considering the cost of the car, spending $750 on charging equipment is really very little and quite insignificant Do you need the HPWC? No, but it is reliable, sturdy and nice décor for the garage.

I have 3 220's around the house and garage. Front, back and inside the garage. I use the plug that came with the car. I get 28 miles per hour charge. Plenty of time to fill up during off peak hours (10pm - 8am). Total cost to run the wiring and put in the 220 outlets was about $700. I also had to upgrade my electrical panel but that was going to be needed soon anyway.

Don’t use 110 unless there is absolutely no alternative—it’s less efficient and incredibly slow!

Thank you all, I am glad I put in the 220. I do not know what HPWC is. But will inquire with Tesla.

Thanks again.

HAHA...I tried to get away with the 110 when I first got the car. WOW. The trickle charge really hurts, especially after a long trip. I struggled until the 220 was installed.

So just like @Felix says....don't do the 110!

We put an outlet that could charge inside the garage or you can plug outside on the same current. When my husband needs a quick charge he leaves it outside to charge.

My model X will be replacing a Nissan LEAF. I have had a J1772 (220v) charger in my garage for the past four years. Do any of you electrical wizards know if there is any disadvantage to using the J1772 charger rather than one from Tesla? TIA

Mark Z | 5 octobre 2015

ikashworth - The major disadvantage is using the included adapter instead of the native Tesla cable.

I have a J1772 and the Tesla Wall Connector. 30 amps for the J1772 is plenty for overnight charging. I normally set the amperage down to 6 amps on the touch screen when only 25 to 40 miles of charge are needed overnight.

Since the charge port can be opened with the key fob, that makes using the J1772 a bit easier.

The Tesla Wall Connector features a button to open the charge port. When hooked to a 100 amp circuit breaker for 80 amps for Model S, it is perfect when you need to charge very quickly.

@Ikashworth. We replaced two Leafs with two model S cars in 2013. I used the Blink J1772s for a while. Messing with the adapter was irritating over time. It takes two hands and an extra step to open the charge door.

My Blinks were wired with 6-50 outlet pigtails so it was easy to unplug the Blink from the outlet and use the Tesla adapter to plug into the 6-50 Blink 240 volt outlet. Tesla no longer sells that adapter.

Then in 2014 I finally got around to installing the HPWC's that I ordered with the cars and never got around to installing.

So now we charge both cars with HPWC's.

So after charging with J1772, Tesla Mobile cord ( UMC that delivers with the car ) and finally the HPWC I prefer the HPWC. If you plan to travel with a UMC in the car the cost difference between buying a second UMC to leave in your garage and buying a HPWC is insignificant.

I chose to operate one HPWC at 50 amps and I installed it with a plug so I can plug in the HPWC or the Blink if a visitor needs a J1772.

Bottom line is you can use a J1772 but after a while dealing with the adapter is just an unnecessary extra pain in the rear. The Tesla system is painless and fast.

@Ali, Tesla does not have an adapter for a 240 volt twist lock receptacle. Twist locks also come in different amp ratings so I can't tell from your post what amperage your outlet is wired to deliver. 240 volts can be supplied thru outlets rated from 20 amps to 50 amps. It is possible to buy or make a third party adapter pigtail to use you existing twist lock but for all the effort it would be easier to just install a supported receptacle.

Here is the online order page for charge cords and adapters.

The simplest solution is a 50 amp 240 volt NEMA 14-50 outlet. The car delivers with a Universal Mobile Connector charge cord that includes the adapter for a 14-50 outlet. If you install a lower amp rated outlet you would need to order an adapter for the outlet and amp rating you have installed. | 6 octobre 2015

@LeonardD: I like your economic thinking. When I got the model S, my wife said that, considering the cost of the car, she should wear a new pair of shoes in it at a cost of only $200. Incremental dollars are still real dollars but, if you have the dough.....

In Australia our standard power is 240 volts.

Sounds like you have a 2nd world problem....

NumberOne | 6 octobre 2015

@georgehawley in FL where I would like to be... Another consideration for me here in VA is that our local power company offers a separate meter with lower rates for EVs. The catch of course is that it can only be used for EV charging, so it has be an HPWC because a simple 240v outlet can be used for other things. I had my HPWC installed so long ago, that the cost is no longer relevant though I did get a tax credit which has since expired.

@Ross, not only is the standard here 110v, but it is also single phase. Things like Dryers and Electric Range Ovens use 240v. outlets.

eric.zucker | 6 octobre 2015

This is what I've prepared for my MX:

There is 3x20A, 230V which is about 14kW. Mennekes Type 2 EVSE which is the European standard.
Alternatively there is a CEE32 three phase (limited here at 3x20A max), or Swiss T25 (3x16A max).
Should cover quite a few use cases.

If one day I have two EVs I will charge them either one at a time, on alternative days, or set a lower rate.

This is great information. For those who already have Teslas do you charge them everyday? Do you leave it charging or unplug once it's full?

Thank you for your help. | 6 octobre 2015

For local driving I run my S85 down to about 30% (about 80-90 miles) and then charge it to 90%. There are many ideas about how to best care for battery life but no definitive recipe. When on the road, using Superchargers, you can have fun by guessing exactly how much energy you need to get to the next Supercharger, barely get there and repeat. That is the way to minimize charging time. Otherwise settle on some conservative amount of charge (maybe your estimate + 25-30%) and don't worry, be happy.

I got a postcard from Tesla saying something along the lines of "A happy Tesla is a plugged in Tesla"

I guess the battery life is better if you keep your Tesla plugged in as much as possible. I try to do that as much as possible. Its so easy and fun....even 2.5 years later. I can't wait for my MX so I never have to visit a gas station again!

Thank you for the info PV and President George! As an aside George, I hope as a fellow Floridian (Does Miami still count as Florida?) I hope we'll meet at a Tesla or some other event soon. Looking forward to getting the X, the order will lock down tomorrow so I can't wait until receive the Production Starting and later the Being Delivered (or however it's worded) updates.

All the best,

If the wheels are not turning it is plugged in, if a plug is available.

Roamer@AZ USA | 6 octobre 2015

Just as a clarification. The standard in the US is 120 volt single phase and 240 volt double phase.

110 and 220 were long ago replaced by 120 and 240. The old terms are still commonly used but what comes out of the receptacle is 120 or 240.
