Model X

High amperage charging option

edited November -1 in Model X
Does anyone know how to access the "High Amperage Charging" option in the design page? It is a $1000 option but it is hard to access - http://gas2.org/2015/11/27/tesla-hides-model-x-high-power-charger-option/ I'm ready to order except for that 1 option. Thanks

    When you are in the design studio just type charger ( anywhere on the page; but you won't see the letters and won't believe anything is happening) then scroll down and it will be at the bottom of the options.

    Thank you - found it and just placed order! Excited!!!

    The article includes the following: "If you are paying a minimum of $80,000 for a Model X, why on earth would you not pay an extra $1,000 to always be able to charge the car in half the time?" But, that statement is not true for superchargers, 110 and 220. Aren't most homes 220? I profess my electric charging ignorance. Isn't it more for destination chargers? If so, is it then worth $1,000?

    An onboard charger is a AC-to-DC charger.

    Internalized AC-to-DC charger is slower than externalized DC-to-DC Supercharger.

    The question is how much slower do you to your charger to be?

    If you want it to be real slow, then equip your home with a 120V socket. It will take about three days to charge your battery in summer.

    If you want it to be as fast as it can then equip your home with a 240V 100A circuit for your HPWC and your higher capability onboard charger.

    Now why anyone in their right mind want to install a HPWC with 240V and 100A circuit for higher capability onboard charger?

    Of course if you have all the luxury of time then choose a slower rate of time.

    Suppose you forgot to charge your car last night, and now you need to charge your car before you go to work.

    $1,000 means it's a 30 minute late for work or 1 hour late for work.

    It could mean 1 hour late for work or 2 hours late for work to wait for enough charge.

    The same principle: when you got home and you need to attend a function but so it's a difference of waiting for 30 minute late for work or 1 hour late for work...

    Also, some owners are on Time Of Use electricity rate.

    Choosing a no additional fee onboard charger may mean you have to pay higher electrical rate due to prolonged charging into more expensive time.

    Paying $1,000 for faster charge may mean you never have to pay a higher electrical rate because it is twice quicker than the barebone charger option.

    Since it is not upgradable after delivery, you are stuck with 48 amps. if you change your mind later.
    Please, everyone, purchase your vehicle with the 72 amp charger option. You will not regret the decision. You will, however, probably receive your vehicle at a later date since the 72 amp charger appears to be back ordered.

    Also valuable for destination charging. It enables you to free up shared charging at some destinations in less time.

    "Paying $1,000 for faster charge may mean you never have to pay a higher electrical rate because it is twice quicker than the barebone charger option."

    I'd be interested to see the math. At the higher rates, how long until you break even on that $1000? Here in Seattle we have no differential rate structure. I have my theories about the answer, but I don't know.

    Tâm, that's greatly over-simplified. You can still sign up for the TOU plan with the 48A charger.

    You would still have the off-peak discount for most of your charging, it's just that <b>some</b> of your charging happens outside the off-peak window. Charging at 48A instead of 72A increases charging time by 50% (or you could say that charging at 72A instead of 48A reduces your charging time by 33.33%). With a 48A charger, you would use less power during the off-peak window (reducing your off-peak charges), and then add some charging time at the household rate.

    So it really depends on how long the off-peak window is, how much charge you need every night, and the off-peak and regular price of power..

    What are the actual rates per kW? If the difference is $1000 a year, at least up here in Seattle at our rates that would be about 10,000 kWh to ring up a $1k bill (actually even more...but 10c is more of a country average). 10,000 kWh is enough to drive your Tesla nearly 27,000 miles...
  • edited November -1
    I suppose you did say 20k miles a year. God I'm glad I don't drive that much...

    But I could also point out that if you are driving a daily commute of 54 miles (20k miles a year) that you can probably still manage to charge that during the off peak window using Tesla software. It's not like you are trying to fit in a full 90kwH charge every night unless you're driving 90k miles a year.

    I could grant you that yes, I suppose the higher amp charger would let you wait more days between charging and then still theoretically fit in all your charging in one night during the low cost window. But I feel like I'm trying to create a scenario where the high amp charger is "necessary" rather than looking at reality. Part of the charm of charging at home is plugging it in every night and having the battery ready to roll every morning.

    I'm a bit dense, so please help me understand this statement by Tesla when you're selecting the option:
    'High Amperage Charger Upgrade
    Take advantage of high amperage power sources by equipping your Model X with a 72 amp onboard charger. This upgrade will only reduce charge times when connected to power sources over 48 amps. Charge rates when connected to 110 volt outlets, 220 volt outlets or Tesla Superchargers will be unaffected."

    I know it does not affect Superchargers. What does "charge rates when connected to 110 volt outlets, 220 volt outlets..." mean? If I (in my next house) install a 220V 100A outlet, will it charge faster than on my current (ha!) 220V 50A outlet?

    @Claudedohrn

    Thanks for pointing out such a confusing statement.

    I think they mean: for the 240V, if your electrical source can only supply 48A and below, the faster charging rates are not any faster than a standard issued 48A charger even if you pay $1,000 extra for the higher amperage 72A charger.

    ^ fwiw, I asked at my local Tesla showroom, and the salesperson said she thought it would only speed up charging if you had a HPWC. I was unconvinced, since the statement could have simply said that, but it is frustrating that with the scarce information available, what little there is should be clearly stated.
  • edited November -1
    For the faster home charging rate, you will not only need the HPWC, but it needs to be on a 220v 100A circuit.

    THEN your charge rate will be 1/3 faster (but not really, due to charge tapering as the battery nears full).

    @Claudedohrn

    She is correct for the combination of 72A charger and standard HPWC set up.

    Mobile connector can connect your power source to supply a maximum of 40A.

    HPWC is hardwired from the wall to supply a maximum of 80A but if your car can take a maximum of 80A if it's a Model S, 72A if it's Model X (if maximally so equipped onboard.)

    Well, I guess my next house gets a HPWC. Thanks.

    All - This is confusing. Tesla's statement is correct about charging from Superchargers or the UMC when attached to conventional 110 and 220 sources wired to circuits less than 48A continuous power. But because some HPWC at home and at destination points are wired with circuits like 100A circuits. These chargers can deliver more current (Amps) than a 48 Amp charger can deliver to the battery. In these cases a 72A charger will cut your charging time period. The time savings will vary, like they say "your mileage may vary." It may or may not be significant depending on your situation.

    In the US the UMC is limited to 40 amps, it will not mater which charger you have in the model X, you will get 40 amps if using a UMC plugged into a 14-50 outlet, less if plugged into 10-30 or any of the other options Tesla makes available for the UMC. If you use a HPWC or a J1772 with a 60 amp or greater source you will get the full 48 amp charge rate using the 48 amp charger. If you have a HPWC or a J1772 with a 90 amp source or greater you will get the full 72 amp charge rate. The 72 amp charger only speeds charging over the 48 amp charger when connected to a HPWC or a J1772 with a 70, 80, 90, or 100 amp circuit.

    "You will, however, probably receive your vehicle at a later date since the 72 amp charger appears to be back ordered."

    Where di you see or hear this? I have seen nothing on the forums and the Tesla config page does not say anything about it causing a delay (they have noted it on other options in the past).

    I am only speculating, based on information gained from this forum and the Teslamotorsclub.com, You may recall the complaint that the first sigs would only receive a 48 amp charger. Telsa then changed their minds and said that the vehicles would come with the 72 amp version. Coupled with the fact that the 72 amp charger option is "hidden" in the design studio, it may lead one to speculated that very few are presently available.

    For what it's worth, I got a call from Tesla today in response to an email I sent. I was told that the 72A charging option will have no effect on delivery dates. I asked him twice.

    Of course...he could be wrong. But that's what I was told. I wasn't going to get the 72A because I think it will be 1) largely useless to me and 2) I was worried it might delay delivery. I'm now considering MAYBE just getting it since it's not terribly pricey as a future proofing. But still on the fence. I have 12 hours to make my decision before it's finalized.

    @speyerj. Thank you. I don't want my SigX delayed any longer than necessary.

    Bumping this up to the first page so folks that are still configuring know how to access it!
