Will Model 3 Supercharge faster than Model S (in miles/minute)?

    Yep

    I'm under the impression that Tesla batteries are power constrained by the SC up to about 70% and then become SoC constrained. So this question is a ymmv and depends on what SoC each battery started at and how many kWh the person wants to add.

    OP-Yes-newer cells longer or deeper insert of charger cable allows more amps/volts. Newer model S and X will have same cells so they will charge faster too. Neighbor got their new X and charges noticeably faster.

    Current battery packs. A smaller battery might be constrained by SOC (which is to say amperage) at a different state of charge.

    Thank you kindly.

    I don't know. Just spoke an model X owner. In 20 minutes he charges from 15 /20 % upto 80% at a Supercharger. He says the last 20% (from 80 till 100%) takes relatively the most time. He never does that, just because of that. At home he charges from 10 / 15 to 100% in 3 to 4 hours. In the regard to charging driving is different he says. He is more aware of "fueling up". The luxurious hovering is the other end of the scale and the balance goes to the positive side.

    For sure. I meant that if a 70 kWh Model S pack can take the max SC output up to ~ 70%, that implies that 50 kWh or more uncharged capacity does not constrain the charge rate of current SCs.

    Then ... if max charging rate in the new cells increases from 2C to say 2.5C, we are close to the bottom 100 miles of Model 3 range not being a limiting factor in SC charge rate. At least, that is what I am hoping for :)

    i very much doubt he charges from 15% to 80% in 20min. Unless he charges twice as fast as all other teslas.

    I don't know, but he said that is the case

    It's possible if you're the only tesla on the given stall, I have 75kWh pack and my peak charge is around 96kWh (over 330 miles/h) it goes do to 50kWh around 80% and to 30kWh around 90%

    Tesla's website updated with a new blog post about charging today:


    Someone noticed that a rendering of a potential Tesla Supercharger/Store/Service location showed an image of the Model ☰ with a more typical 'binnacle' at the driver position:

    supercharger-expansion-01.jpg supercharger-expansion-02.jpg

    Looks like a placeholder rendering of the car to me. I doubt there will be a traditional hooded binnacle bump in the final Model ☰. But I was gladdened to see that blog post.

    It isn't quite the announcement of the 'Tesla Depot/Waypoint' sites I'd like to see, but it's close enough. I do like the use of the phrase 'ubiquitous in urban centers' as that will hopefully, finally, cause EV Naysayers to [SIERRA TANGO FOXTROT UNIFORM] when it comes to eternal queries about 'What about apartment/condo dwellers?' and the like. The closing paragraph certainly draws a line in the asphalt:


    "Tesla will continue to lead the industry with the fastest, most advanced charging technology in the world and continue to build the only cars capable of leveraging that power. The ongoing expansion of the networks will ensure that Tesla drivers are able to quickly and easily charge their vehicles no matter what, and that a seamless charging experience remains our priority."

    Why doesn't have the solar roof not one or two rows more. Than the cars are in the shade, cooler and the ventelation won't be on.

    Apart from the updated supercharger maps showing virtually blanket coverage in California and along the I-95 corridor, this is my favorite part of the blog post. Seems to be another hint that Supercharger V3 will leapfrog the upcoming generation of 150-300 kW CCS stations in terms of power output. And, unless my reading of the word "cars" is another "spaceship controls" moment, it appears that this step-up in power won't only matter to the Tesla semi and pickup.

    Look more closely. You'll notice the Supercharger locations without solar panels are next to a row of trees. The presumption is that as they grow, they will provide more shade (even though the Supercharger spaces are to the South side of some). Conceptually, it is best for their sites to be as 'green' as possible. There is also the fact that in California at least, most municipalities require a minimum amount of greenery at commercial sites.

    I was referring to the stalls with solar panels. When the roofs will have two more rows than the cars will "sit"in the shade

    It's a rendering. Those trees are never going to grow. :) Why not show the trees at full growth if that is why surfaces don't have solar panels....

    Thank you kindly.

    Oh, they can grow... Just let me at the CAD workstation for a few minutes. Tweak the x, y, and z axis dimensions and... PRESTO! Giant trees, all around! w00+!

    Sure, they could potentially 'shade' all the driveways throughout the location with overhead solar panels. But many would consider that ugly. And Tesla might find it unnecessary. Besides, they would need more substantial supports and stanchions to hold up the canopy of solar panels. That would take up more space, and also be ugly. Cars shouldn't have to drive through a forest of pylons when negotiating the parking lot.

    I did like the style of this display from the Tesla Booth at the Paris Motor Show a bit better, though:

    That would be the plan! Redwoods are majestic, beautiful, and truly awesome to behold.

    I don't think its a matter of the fact that its a car.

    Lets say that a charger can supply an infinite amount of current to charge a battery bank. At that point it wouldn't matter how many batteries are on charge. They will all charge at the same rate.

    However if I try and charge a battery bank with my cell phone charger ( limited current ).....more batteries would take longer than a single battery to charge.

    Each charger (i.e. two parking spots) at 120 kW would require at least 800 meter² of solar panels (at a utilization equivalent to sun-hours). So yeah, more panels are necessary.

    Thank you kindly.
