!!!!!!!!!! HIDDEN 72 AMP CHARGER!!!!! DONT MISS IT!!!!!!

!!!!!!!!!! HIDDEN 72 AMP CHARGER!!!!! DONT MISS IT!!!!!!

People please be sure to check out hidden 72 AMP CHARGER that Tesla has hidden in configuration page.
Please make your own decision. This thread is not intended to influence anyone to get higher capacity charger. Please note that "Supercharger enabled" is different from "High Amperage Charger (72 AMP CHARGER)".
How to find the hidden option-
@SunShineBuildin- "type the word charger while on the configuration page to have High Amperage Charger Upgrade magically show up to be selected as an option for an extra $1000."
@vperl- "TYPE Charger anyplace on order page then scroll to the bottom of page. The easter Egg pops out

Type only the word.

Charger"

When will 72 Amp charger be beneficial-
@aesculus- "Home charging is generally not the issue. Try going to a hotel with other EV's wanting to charge and see how many you can get down overnight waiting for a few chargers. If you had a faster charger you might be able to get in, charge quick and then open it up for others. Or if a valet is managing the charger, prove to them that your window is smaller and so you should get in first."

@speyerj - "If you are not at home and not near a supercharger AND you find an EV charging station that is capable of delivering 80A (such as an HPWC or high amperage 3rd party system) then you can charge at the increased rate with the upgraded charger."

"If you find a destination charger that delivers 80A and you need/want to get as many miles of range as possible from the destination charger in a given period of time...you benefit from the upgraded charger."
"If you foresee a lot of times where you're going to get home with an empty battery and need to turn around very rapidly to drive more miles, then perhaps home charging needs to be as fast as possible."

When will 72 Amp charger wont be beneficial-
@speyerj- "If the charging station you find can only delivery 40A, your upgraded charger is worthless. If you are at a supercharger, the upgraded charger is worthless. If you are at home and have no problems with the recharge taking an hour per 30 miles replenished, the upgraded charger is worthless (i.e. If you routinely are plugging the car in for 10 hours daily and don't need to charge any faster)."
"If you foresee that the majority of your home charging will be overnight, I don't feel the need for higher amperage is really there."

where it is?

Ankit Mishra | 05. Januar 2016

Type charger anywhere on the configuration page. The hidden option appears.

ali | 05. Januar 2016

@ankit thanks for the heads up. Do you know if the middle / 2nd row seats completely fold or not? I heard rumors. And congrats on getting X.

lolachampcar | 05. Januar 2016

I believe only the rears will fold away to increase rear hatch access storage.

vperl | 05. Januar 2016

Wonder who the Genius was to hide the 72amp option ?

Seems to lack a sense of Tesla playing a silly game.

Childish at best

Ankit Mishra | 05. Januar 2016

lol. I don't care about seats. Just tell me whether I can plough my field with this thing or not.

Ankit Mishra | 05. Januar 2016

Whoops! My above post is meant for @ali. While I was creating a brutal joke, @vperl and @lolachampcar posted.

Shelmire | 05. Januar 2016

please explain why I should care? thx

Ankit Mishra | 05. Januar 2016

Because in the end... why shouldn't you? What else is there to do in the world but care, when everything is the way it is and you've seen what it's like not to care ... how can you afford not to? Caring isn't optional when you've looked at the world. It's like breathing, it's necessary. And the most important reason? Because deep down inside, you know that you already do. You just shouldn't have to lie to yourself any longer.

Ankit Mishra | 05. Januar 2016

That was the best Google can come up with. If you can specify, what exactly is being asked from you to care about I might be able to give a better answer.

AlMc | 05. Januar 2016

@ankit: Thanks for offering some constructive criticism about something TM. It does appear to be an odd decision about 'hiding' an optional feature whether you would want it or not.

NumberOne | 05. Januar 2016

While it is a pure guess, I feel that Tesla may have put more thought into hiding the option than you might think. Unless you do a lot of travelling that includes destination charging, or have an actual HPWC at home, there is no reason why the 48A charger would not suffice. Tesla has access to a lot of data from cars (they get constant feedback directly from on board computers, so they know more about how the majority of Tesla owners charge their cars than you might think.) Perhaps they feel that the fact that the option is hidden forces people to think more about whether they really need it or not, VS just having a check box.

Ankit Mishra | 05. Januar 2016

I understand your point. But there are people who knew about the charger and wanted it but forgot to add it. They remembered it few days later and they added it then. This creates a chance for bitter experience. And I believe Tesla has its reason for doing this. But it takes choice from a person who though might not be an EV nerd but upon giving information can make an educated decision. I do not claim to be right here. I maybe wrong as I have been many times.

AlMc | 05. Januar 2016

FYI: I have sent in an email to TM (NASales) asking about the reason for this 'easter egg'. IF I get a response I will share it with you.

aesculus | 05. Januar 2016

@LeonardD: I would tend to agree with your statement. I am surprised by the number of current MS owners who insist that the dual chargers are needed at a supercharger.

vperl | 05. Januar 2016

Many Tesla owners have not bothered themselves into reading about the car in detail. They could easily read that the onboard charging system is AC only sine your using AC 40 or 80 AMPS.

WHILE THE SUPERCHARGER USED Direct Correct.

Bet a few owners do not have a clue or care about their care to know much more than where the pluh-in is located or know of the difference between ALTERNATING CURRENT ( AC ) or Direct Current ( DC ).

Low information owners present Tesla with many situations the the owner could avoided, by reading the owners manual or this web site.

Low information owners just blindly walk, drive while texting then wonder why things happen.

aesculus | 05. Januar 2016

@vperl: Low information owners just blindly walk, drive while texting then wonder why things happen.

I suspect this will be Tesla's future. So you better get used to it, and so should Tesla. :-)

Jonathan | 05. Januar 2016

Thanks for the tip. I now see the 72 amp charging option. I think I will be charging on a 220 at home and occasionally at a Super Charger. From what I read, having the 72 amp option will not affect either. Can someone explain to me when having this $1,000 option might be of benefit? Thanks!

aesculus | 05. Januar 2016

@Jonathan: Will not change at the Supercharger. At home or at a destination like a hotel you will be limited to 48 amps without the option. If you only have a 60 amp breaker on your 220v at home them you will loose nothing. If you only have a 50 amp breaker than you will be limited to 40 amps, so again the option will not help you.

You basically need a 80 or 100 amp breaker to use the option away from the SuperChargers.

speyerj | 05. Januar 2016

If you are not at home and not near a supercharger AND you find an EV charging station that is capable of delivering 80A (such as an HPWC or high amperage 3rd party system) then you can charge at the increased rate with the upgraded charger.

If the charging station you find can only delivery 40A, your upgraded charger is worthless. If you are at a supercharger, the upgraded charger is worthless. If you are at home and have no problems with the recharge taking an hour per 30 miles replenished, the upgraded charger is worthless (i.e. If you routinely are plugging the car in for 10 hours daily and don't need to charge any faster).

If you find a destination charger that delivers 80A and you need/want to get as many miles of range as possible from the destination charger in a given period of time...you benefit from the upgraded charger.

Jonathan | 05. Januar 2016

@aesculus, @speyerj, thank you for taking the time to explain. For me the real benefit would be to upgrade my breaker at home for the 72 amp faster charging, which will be most of my charging.

eddiemoy | 05. Januar 2016

anyone know why tesla would do such a thing as to hide it? you can't get it after you take delivery, so it is only screwing the owners!

speyerj | 05. Januar 2016

@Jonathan

The question then for you is, what will you gain by upgrading to faster home charging? How often will it matter to you that your car charges in 4-5 hours instead of 8-9? If you foresee a lot of times where you're going to get home with an empty battery and need to turn around very rapidly to drive more miles, then perhaps home charging needs to be as fast as possible. If you foresee that the majority of your home charging will be overnight, I don't feel the need for higher amperage is really there.

Jolinar | 05. Januar 2016

Is this 72A thing real? Or just a brutal joke on us Tesla believers?

For how many Amps it will be rated in EU? 3x24A?

Jonathan | 05. Januar 2016

@speyerj, That is a great point. Chances are that I will come home with more than 50% charge remaining on most days. I just saved $1,000!

socalsam | 05. Januar 2016

I just confirmed my car and did not do the 72amp charger. I lived on charging my model s on a 110 plug for 18 months. I don't need 72 amps. Its a waste of a $1000 bucks imho.

CalabasasKid | 05. Januar 2016

Just like on the MS, I'm sure they will offer a optional post-delivery install of the second charger for a slightly higher fee than the $1000 factory fee. Unless, it's not done with a second charger but instead is a swap-out of the lower amp unit in favor of the higher one. Who knows.
One thing that's safe to say, if the MS charges at 29 miles per hour using a 40 Amp setup, it appears the MX will do it at around 35 miles per hour using a 48 Amp setup so long as your electrician installs a 60 Amp max rated circuit instead of the usual 50 Amp circuit. 35 miles of charge per hour is impressive. Are we sure the MX comes standard with a 48 Amp setup?

aesculus | 05. Januar 2016

Home charging is generally not the issue. Try going to a hotel with other EV's wanting to charge and see how many you can get down overnight waiting for a few chargers. If you had a faster charger you might be able to get in, charge quick and then open it up for others. Or if a valet is managing the charger, prove to them that your window is smaller and so you should get in first.

Jolinar | 06. Januar 2016

yea, faster charging is not for home charging, you have enough time at home. It is for travel, especially in places where are none or very few of SuperChargers.

And of course for people who are used to ICE cars and laugh at us with 8 hours charging time.

I have used DualCharger on Model S so many times I can't count them just because there are no SuperChargers anywhere where I travel. I wish I lived in California or Germany :-D

AlMc | 06. Januar 2016

No word about the 'why' the hidden Easter egg from TM at this time. I doubt there will be one but I will keep trying.
As to being able to add it after delivery: Who knows.

eddiemoy | 06. Januar 2016

@AIMc, it says clearly on the option that it cannot be added after delivery.

aesculus | 06. Januar 2016

There is a whole thread over at TMC that is dealing with the fact that the 48 and 72 amp chargers are one in the same and just activated by sw. If that was the case I would be surprised by them stating it must be installed at original order time. Some are also speculating the chargers may be the same but the wiring is beefier on the 72 amp option.

We will have to wait until the tear down of both models to find out I would guess.

AlMc | 06. Januar 2016

@eddiemoy: Thanks. So, all the more reason to make it a visible option for everyone.

kittylitter | 06. Januar 2016

Virtually anything can be added/altered after delivery...the question is, "how much would it cost?"

AlMc | 07. Januar 2016

@kittylitter: TM should avoid the issue: Make it visible on the configuration page and add a description about why you might want the 48/72. If there are questions the sales team should be able to answer them.

I won't speak for everyone, but I would be pretty upset if an option that I would like to have was available to some but hidden from me.

NumberOne | 07. Januar 2016

Fortunately we know it was, so no one can honestly feel slighted. That said, I also do not quite see why they hid it.

NumberOne | 07. Januar 2016

Hidden from all I meant to say.

elguapo | 09. Januar 2016

@CalabasasKid The configuration tool clearly states he 72A will not be available post-production as an add on. I chose it, but I definitely don't think it's a major decision either way given the current and expected EV infrastructure in the US.

AlMc | 09. Januar 2016

@elguapo: I agree that the 72amp onboard charger is not needed by most X owners now, or in the future.

Personally, I am willing to spend the extra $1K for the security/time saver that it *might be* in certain situations.

Specifically destination charging/L2 chargers when a SC is not available or there is congestion/time constraint when using a destination/L2 charger.

proven | 09. Januar 2016

I keep wondering why this is hidden.

CalabasasKid | 09. Januar 2016

I just want to know one thing. At 48 AMP (assuming your electrician wired you a 60 AMP circuit), will the MX charge at 35 miles per hour instead of the MS' 29 miles per hour at 40 AMPs??

Tâm | 09. Januar 2016

@CalabasasKid

You might want to change your expectation when switching from S to X.

S has more range.

X has less.

Thus, with exact charger and battery, rated miles for the X is less than the S.

@FlasherZ mentioned somewhere that the X 48A rated charger spec is approximately:

25 miles per hour on a NEMA 14-50.

30 miles per hour on a HPWC.

CalabasasKid | 10. Januar 2016

What does the reduced range (due to the heavier weight) have to do with the amperage difference between the two vehicles? I'm only referring g to the rate of charge? The battery pack on a MS 90 is the same as on an MX.
With that said, any car should charge quicker at 48 Amps vs 40 Amps. Am I missing something?

Tâm | 10. Januar 2016

@CalabasasKid

Very simple.

Suppose both the X and the S has exact the same 120 kW 400A 400V that can charge their exact 90 kWh battery in exactly 1 hour.

So:

Time to fully charge a 90 kWh battery for an S:

1 hour

Time to fully charge a 90 kWh battery for an X:

1 hour

So, in 1 hour, the rate of charge for an S is:

288 miles per hour.

And, in 1 hour, the rate of charge for an X is:

257 miles per hour.

It's the same 1 hour, same rate of ampere, so you tell me, should they have the same miles per hour charge?

Tâm | 10. Januar 2016

@CalabasasKid

Put it in another way, the batteries are exactly the same and swappable.

That means it doesn't matter battery which goes where, it's 288 miles for an S and 257 miles for an X.

However, their rated miles are not the same and not swappable.

That's because:

It takes less energy to go 1 mile in an S.

It takes more energy to go 1 mile in an X.

Thus, it takes less time, less energy to charge 1 mile in an S.

And, it takes more time, more energy to charge 1 mile in an X.

CalabasasKid | 10. Januar 2016

Ahhh. I see. Bummer

Tâm | 10. Januar 2016

@CalabasasKid

Actually, you've have been correct in your thinking all along:

Yes, given everything the same in S and X, the charging speed in percentage rate of State of Charge IS THE SAME.

As the example above, to get to 100% State of Charge in both batteries, it's 1 hour.

They both get to 50% State of Charge at the same time too!

However, when you calculate the miles for each battery, it's less for the X and more for the S at any percentage, such as 50% or 100%.

It's the miles that threw you off, but you are right about the percentage rate (faster in 48A than 40A).

AlMc | 10. Januar 2016

Bump for people that may get the call tomorrow to configure.

vperl | 10. Januar 2016

Talking in gobbley book, is silly

Charging at a certain Amp will deliver same mileage to two batteries if discharged the same and are similar in age.

But, gobbley gook , blathering confusion is silly

AlMc | 11. Januar 2016

Bump for people just recently asked to configure.
