Hey thanks for pointing out my meager contribution. 👍🏻😎 Adding on here, 4 v3 scers is equal to 1 of the new v4 mwh+charger. Tesla has multiple 80-110+v3 250kwh unit station's in service. So they know how to plan for build out and deploy massive grid powered charging stations. Including those with solar canopies and bess. Next down in Florida earlier this year? Using new pre fab slab techniques made off-site with the scers pre assembled and wired on top. in just 8 days from the approval of permits they installed and powered on a 12 individual v3 scer station So once they get going they can really get going. Further they will be getting ira funds starting Jan 1st 2023. And in 2022 alone tesla installed and activated over 11,000 new scers world wide. 👍🏻

I would love to hear more about why the carbon sleeve makes so much difference. I believe all other EV motors are over sized so they have enough power at high speeds but then have to be software limited at low speed. Being able to spin at such high RPMs means right sized power at low and high speeds. When applied to a sedan it could mean a tiny motor. It’s like the equivalent of having a much smaller regular electric motor with a transmission but without the extra weight, expense, space, complication, and reduced reliability. If a plaid motor is a third of the size and put into a model Y, how much more efficient would the Y be?

carbon sleeve for high rpm. Probably to eliminate gearbox changes, single fixed gear ratio 0 to max seed. I would guess the single motor is geared higher for efficient high speed, and the additional 2motors lower for torque and then disengage.

[@abstractreasoner]

@@pietersmit621 I’m curious about how much more efficient the carbon sleeve can make a Model Y

[@sachitdaniel6688]

IIRC, the further away the stator coils are from the rotor, the more of the magnetic flux is wasted flowing through the air instead of the rotor. The force drops as the inverse cube of the distance. I also think that some of the flux gets wasted flowing through wrong paths in the rotor creating unnecessary hysteresis losses (The plaid ipsynrm plaid motor needs some complicated flux geometry to achieve the high torque, speed and efficiency.) Please check the last bit though, I'm not sure of it's accuracy. The carbon fibre sleeve ensures that the rotor doesn't expand with heat or the very high centrifugal forces. This allows the gap between the rotor and stator to be reduced, increasing the efficiency of the motor.

[@truhartwood3170]

So it doesn't eat itself. Spinning at high speed forces the components outwards. The whole thing wants to fly apart. The carbon sleeve does the 'nope' on the flying apart part.

The speed of the vehicle means that you get places faster so driver breaks might be less. You might need to strap your load down better for acceleration.

[@rogergeyer9851]

Lossy: But except for steep hills and starting off, it's not like there's lots of major acceleration going on, except for, I suppose, stop and go traffic. So they'll save a little time, but on a typical long major highway run, I don't think that's a significant percentage of most trips. Fully loaded, the 0-20 acceleration figure is 20 seconds (vs. the insane 5 seconds for just the cab, without having to change gears, of course). I'm not convinced that's a big problem if the truck is loaded in a reasonable way (after all bumps, deceleration for stops, etc. is a normal thing already).

So electric trucks are not subject to speed limits? Awesome

In the presentation they showed a Semi carrying 11 jersey barriers as "fully loaded". From the typical length of a flatbed trailer of around ~50ft one can estimate the size of these jersey barriers. Here in europe a typical size of one barrier would be around 2.5m (8ft) at around 1.400kg (~3000lbs). However it could have been the more US-typical jersery barriers of 10ft at ~4000lbs each, which still would line up with the estimated size of the trailer. That would result in around 44,000lbs or ~20t of max payload for the long range version. Not bad.

Oh - when assuming ~82,000lbs max. grossweight, subtracting ~10,000lbs for the trailer and 44,000lbs for payload, that'd leave us with ~28,000lbs (~12,5t) for the semi itself. That would be around 50% more than a regular european truck that weighs in at around ~8t (~18,000lbs). Difference to a typical US diesel - semi could be smaller, as those can also come in somewhere from 20,000lbs - 25,000lbs from what I read.

Can't we infer the rough weight of the Tesla semi? Hauling 11 10 ft. Jersey Concrete barriers would be about 44,000 lbs, and let's assume 1000 lbs of chains to secure them, for a rough cargo for the test trip of 45,000 lbs. So that would make the total semi and trailer weight (82,000 - 45,000) lbs, or 37,000 lbs. So unless we learn differently, it seems like an early estimate for the Tesla semi would be 27,000ish lbs (I assume a 10,000 lb. flatbed trailer). And given that big Tesla battery compared to the others, an extra 5000 lbs isn't all that big a penalty, especially given the power and range and fast charging the Tesla offers. And I think that's pretty consistent with the Tesla claims -- the semi truck weight would be in the ballpark of diesel semi trucks. I could be wrong, obviously, and I'm making some assumptions, but I think this makes sense in a ballpark sort of way, given what we know.

Mr Thurston thanks for noting the error in 50% - but ; you have to get up to the top of a mountain pass before you can regenerate down; and you can only regain as much battery as there is available, if you get to the top with a recent recharge and still have 60% - the max you can get is 40%. lastly no regen is going to hold back a 40 ton vehicle so braking will be needed reducing potential regen. Gentle short hills. you can do better. If you spend 3 charges going up you can only get a max of 1 going down. Real driving reports will give some numbers; I figure it won't be better than other existing vehicles which new is about 30% so you get one free 100% charge for every 3, that will degrade with years on the road.

[@BigBen621]

The only way you could have less capacity available in the battery for regen braking than the potential energy at the top of a pass, is if you charged at or near the top of the pass; and no one would put a charger there for that reason. Even if you did, drivers would know that and only charge enough so they'd get full regen braking on the way down. If a Tesla Semi has enough traction and power to pull a 40 ton vehicle up a hill (which it does), it has enough traction for regen to control its downhill speed. And a number of things are helping on the way down. First, the charge available to go back into the battery will be only about 80% of the energy to make the climb, due to drive train efficiency losses both ways. Second, air and rolling resistance will be helping retard the Semi's speed on the way down. Third, weight transfer will decrease the weight on the drive wheels on the way up, but increase it on the way down, increasing traction. Evidence that regen can provide all necessary braking on the descent is the unequivocal statement during the delivery that "brakes are cool at the bottom of the grade". If the regen weren't enough to control speed, friction brakes would be used; and if they were used, they'd be hot. Since they weren't hot, they weren't used. If you own a Tesla, you know that the energy graph shows that most of the energy used in a climb is returned through regen braking. And finally, the graph of the 500 mile range test shows that most of the energy needed to climb Tejon Pass-much more than 30%-is returned by regen before Pasadena. Just look for the several places where the blue energy line switches from sloping down to the right, to sloping up-these are where regen braking is used. Looks like in your desperation to disparage the Tesla Semi, you're just making stuff up; but even a blind squirrel finds a nut once in a while, so I urge you to keep trying!

[@EQINOX187]

Sorry but no the Tesla Semi does not destroy the competition for many reasons, You keep going on about how the MPG efficiency of the Tesla is so much better but the reality is raw mpg efficiency is meaningless what matters is MPG for actual cargo moved, the average semi is 20 ton with a cargo of 20 tun for a total of 40ton), and if we look at the launch video where the Semi is pulling a load of concrete walls up the hill and on the 500 mile trip and where Musk states that the truck shown is ( fully loaded ), and well pretty simple math ... we have 11 concrete walls of standard size so about 525kg each and it has 11 in its max load so that's about 5775kg or 6.4 ton as the max cargo capacity of the Tesla semi as stated by Musk, and so the load capacity of the Tesla Semi is 3 times less than that of a Diesel Semi meaning that to transport the same cargo you would need at the very least 3 Tesla semi's to do the job of just one Diesel Semi, and so since you like to use the MPH efficiency you would need to take that 22MPG figure you have and divide by the number of needed trucks and so 22 divided by 3 means that the Tesla has an actual efficiency of 7.3MPG, so better than thew average Diesel until you factor in that you need to buy 3 Semi,s and hire 3 drivers to all do the work of one. As for the other Electric Semis well they understand something Tesla does not, they know that range and load capacity do not mix well and so they opted for a smaller battery because they did the research to find out the average range for a distribution company and figured out that electric would be no good for long range transport unless they loaded it down with batteries and as we know that impacts cargo capacity and they learned through research that they did not need much more than a few hundred miles range, and so they opted for a smaller battery so they could get a cargo capacity close to that of a Diesel and still satisfy the range average from the research, so its not that these other company's could not put a bigger battery but rather that they used their brains and built a semi that did not impact the cargo capacity, where as Tesla wanting to have the biggest battery unzipped and slapped it on the desk but at the exspence of cargo capacity. Finally the Tesla semi has to be actually out to have a chance and despite the launch it is not actually out and none of the production Semi's are actually going to company's that pre-ordered and as stated by Elon they will all be staying in house with Tesla

[@EQINOX187]

@@BigBen621 Incorrect and its clear you did not do the math, in the US there are many types of barriers and many all look the same like K-rail and Jersey and they all come in different weights from the extra reinforced ( heaviest ) to the ultra light non reinforced, The ones being used in this test are of the light weight variation and simply math tells you this. We can easily work out the total weights using math, so if it is as you incorrectly say 44,000 lbs well ad that to the average semi and trailer which is 30,000lbs and you have 74,000 lbs still less than a diesel meaning you would still need 2 Tesla trucks for the one job. However as most know the tesla semi is far far heavier than a standard one and so if the load is as you claim 44,000 lbs that leaves 36,0000 lbs for the semi and trailer and yes i am using the max load of 80,000 because the 82 only applies to Cali and so non standard, and so load = 44,000 / Trailer about 15,000 for a total of 59,000 just for the back and the Semi its self is estimated to be at least 27,000 on its own and you can estimate this by again doing the math calculations, so add it all up and it is way above the 80,000 limit and also above the 82,000 Cali limit

​@@EQINOX187 Please, then, enlighten us on just exactly which barriers were used, such that they only fit four long and three wide on an 8' x 53' flatbed.

" 82 only applies to Cali". 23 USC 127(s) begs to differ with you: "A vehicle, if operated by an engine fueled primarily by natural gas or powered primarily by means of electric battery power, may exceed the weight limit on the power unit by up to 2,000 pounds (up to a maximum gross vehicle weight of 82,000 pounds) under this section." If you weren't aware, USC means U.S. Code, which applies in all states. "... the Semi its self is estimated to be at least 27,000 on its own" This is no more than wild speculation; and so trying to estimate total vehicle weight using this figure is meaningless.

[@EQINOX187]

@@BigBen621 Actually no the 27,000 figure is not wild speculation or well it is if you are not smart enough to figure it out, it is common knowledge about the Trucks weight because it can easily be worked out, Tesla can do many things but they are not above the laws of physics, we know the weight of a steal rolling frame and we know the weight of a truck cab we can estimate the weight of the motors and transitions by sizing up existing ones / we know the weight of the battery because nether you nore tesla can bend reality or battery weight and so we know its a 900kw battery and we know that with the batery they are using they are getting 200watts per kilo so about 4.500 kilo or 8,000lbs, so 8,000 just for the battery then you have 3 very heavy motors and then you have 3 heavy transitions for those motors, So no not wild speculation at all and also it does not strike you as strange that when ever Musk is asked to clarify the weight of the Semi he point blank refuses to answer, it does not make your brain cells spark wondering why he is so adamant about not telling anyone including company's an important fact like the semi weight, but hey like i said we can use brain cells to figure it out with a reasonable margin. As for 23 USC 127(s) sure you are right but you are also wrong because many roads in the US have weight limits and will not allow over what amount is specified on the sign. As for the barriers used well that's easy they are K-Rail 10' light weight non reinforced, if you do your self some googling you will find a video of the Tesla's trailer being loaded and they where using a small fork lift and you can even see the the model of the forklift and well a little google tells us it has a max lift capacity of 2000lbs, so each of those concrete barrier has to be at max 2000lbs which falls inline with K-Rail 10' light weight non reinforced barriers, they look exactly the same have have the same dimensions just way lighter

the point is that this particular route is not typical ; going the reverse direction they'd be lucky to make it half way. Going down the 1% gives a sigificant opportunity to use the regen to make it up the grapevine. No traffic means they intentionally planned that LA has heavy traffic most of the time it would be nearly impossible to avoid some stop and go. My point is this is a contrived example - well see when real drivers drive real routes witht real cargos

[@BigBen621]

You're making it clear you have virtually no understanding of the physics of regenerative braking. There would be *no* regen braking on a 1% slope, because the losses from rolling and air resistance would far exceed the gain from the slight downslope. If you had the mathematical ability, you could use the equations in the video you linked to to determine how steep a slope would be required to get regenerative braking at any speed and load.Further, even if the grade were steep enough for regenerative braking, in order to gain enough energy to make it up the Grapevine, they'd have to descend from a significantly higher elevation that the top of the 4,100 ft. Grapevine; and as you can easily see from the chart of the trip, the highest elevation in the 150 miles prior to the Grapevine is around 1,000 feet. I don't know what you mean by "no traffic". There's no time night or day when you can get around or through LA with no traffic; and the time lapse photo shows instances when the Tesla Semi is at a standstill in stop-and-go traffic. Because the run starts and ends at about sea level, and climbs the Grapevine about in the middle, the return run would be virtually identical. Feel free to continue with your delusional posts; but you clearly don't have enough technical knowledge for a rational discussion, so I won't waste my time on you any more.

Thanks to regenerative braking, traveling through in the mountains has less effect on range than you would expect. I've driven my Model 3 up Pikes Peak and back down without using any more kWh than would be expected on mostly level terrain (going uphill consumed significantly more energy from the battery, but the battery was recharging the whole way back down). Slowing a Semi down with regenerative braking also should be much safer than risking overheating of brakes. After my trip down Pikes Peak in the Model 3, the brake rotors were cool enough to be comfortable to touch. Also, in contrast to gasoline and diesel engines, electric motors don't lose any power or efficiency at high altitudes. Being stuck in an overnight traffic jam shouldn't be a big concern either. Tesla has been using heat pumps on their cars for a few years now, which are much more efficient than resistance heaters. The heat pump in Tesla autos consumes about 0.75 kW and my guess would be that the heat pump in the Semi could be more like 2 kW, so keeping the cab at a comfortable temperature while sitting still for 12 hours would consume about 24 kWh (from the 900 kwh battery) and reduce the range by about 14 miles.

I know this might sound naïve but why on earth would a commercial truck line give a drive range empty??? Like the sole use of this truck is to carry a load 🤣😂🤣😂

[@Cleanerwatt]

Agreed.

Watch John Cadogan Auto Expert's article on KZbin. "Tesla Semi: Worst big rig ever" This guy does his homework.

[@Mark_Young05]

I'd have to agree on this, He's one of those guys I love to hate. He always gets it right though. He rightly predicted back in the mid 2000's that Australia wouldn't have a car manufacturing by 2019 and he was with about 14 months of that timeframe

How much does the Tesla Semi weigh by itself?

[@richardcalon3724]

@not today Why the heck is it estimated? Tesla has presumably just delivered a production unit to Pepsico so why couldn't they weigh it? The answer is they did but don't want to give out that information, the question then becomes why not?

[@mikafiltenborg7572]

Tesla SEMI truck weight 17000lbs

[@mikafiltenborg7572]

@not today Tesla SEMI truck weight 17000lbs + Trailer 65000lbs = 82000lbs total = legal for electric trucks.

[@mikafiltenborg7572]

@Jack Smith Tesla SEMI truck weight 17000lbs + trailer 65000lbs = 82000lbs total =legal for electric trucks.

[@229andymon]

@not today With 4680 we can assume either the weight can be lowered, offering more freight, or the weight maintained and range extended? Wonder which they'd go for?

[@angryeltrucker6326]

Fun fact, I had no idea about other ev semi trucks. Thought tesla was the only one

[@JC-pm5sh]

But the stock price is keep dropping man. Some say it will drop below $100 bro. your thoughts?

[@xanafein8453]

These aren't going to work in the current industry environment. Parking is scarce, charging stations capable of servicing the high volume of trucks on the road don't exist. Range is less than half of a diesel rig. Best use for these things is gonna be short haul. OTR and maybe even regional dedicated aren't going to be able to realistically use these rigs.

[@biscuitapocalypse5883]

5/6 ton payload moved by 35 ton truck and trailer. Game changer 😂

[@biscuitapocalypse5883]

I've invented a diesel truck that can do a 2000 mile journey without refuelling. It's a regular diesel truck with a *massive* fuel tank. 😁

[@swhbpocl]

@@biscuitapocalypse5883 Lame. If you load a Tesla Semi with diesel (say 20 ton) and a dieselgenerator, you get a range of about 55000 mile. Or two revolutions around the world with a margin 😅

that semi has a stated higher efficency than my skoda enyaq....

Of course! Skoda EV is just a VW in a nicer costume.

Tesla looks cool but not if like to bring family with you. I wonder if gov will give weight exemptions to etrucks like they give trucks with apu. I would like to see how there recharge stations will work. There is no truck parking right now.

[@thatdude5328]

Looking forward to paying more for supercharging to help finance Tesla's semi take over.

[@bouquetchocolatesandconfec77]

People PEOPLE!! There is NO infrastructure built to charge any fleet of ESEMI trucks. Think about that the USA is still trying to get ecars charging stations lol and now skid mark throws esemi’s. Take a look at a fleet of 1000 esemi trucks all needing charging as they travel. You would need charging stations just like fuel stations- do you see that happening now? Yes right now how many pilots or loves or TA are building charging stations- not a one. Doesn’t that make you think?? Stop sipping the Def and really think about this // it will take a major undertaking to build the charging systems need for a fleet of 100 not to mention a 1000 esemi trucks. Relax it will happen in about 25 to 30 years.

[@BigBen621]

@Jonny And you still know this how?

[@BigBen621]

You may not be aware that Tesla built a virtually worldwide network of Level 3 DC fast chargers in ten years...

[@Mdrolet77]

You can produce 15.14kwh with a gallon of diesel in a diesel generator. So if the semi takes 1.7kwh/mile and the diesel truck does 10 mpg well the diesel truck is actually more efficient than the Tesla Semi.

[@miguellopez3392]

The tesla gets 1.7kwh a mile at 60mph 82,000lbs GVW, a semi truck gets 6mgp at 80,000lbs 30mph GVW.

[@Mdrolet77]

@@miguellopez3392 Says in his chart the cascadia does 9-10. All im saying is if that's really the case the the Tesla can still improve those numbers. They should also do city rating for the Tesla. Having regen braking with those loads in low speed stop and go is such a game changer.

[@miguellopez3392]

@@Mdrolet77 and other sources put it between 2-7 depending if there are hills or not, yes the numbers can improve but it's already pretty good, and I don't think diesel is going to be cheaper in 10 years

In Tesla semi video , how much do those Cement dividers on its bed weight ??

[@DarkSmugLoser]

That's the big question on the internet. Some are saying it was loaded with 30% of a normal ICE Semi load. But we'll find out the truth once a third party tests.

[@truhartwood3170]

That was just for the photo op. It was not meant to showcase the full capacity of the truck as far as I know. That was certainly not the truck used in the 500mile test run.

[@richardcalon3724]

@@truhartwood3170 If it wasn't why was the video put out suggesting it was?

[@truhartwood3170]

@@richardcalon3724 it was just used a lot in the background when they were talking about it. In fact it was used over and over again in lots of places. I think they just really liked the shot - an obviously loaded down semi passing a diesel truck on a steep grade on the highway with a setting sun in picturesque mountains. If that same shot had been done with a box trailer everyone would have said the trailer must have been empty, or filled with extra batteries... Or a jet pack.. You know Tesla FUDsters. It was just B roll though. No one ever pointed to it and said "look, that truck right there is hauling 81,000lbs 500mi! That video came out later and showed they were pulling a standard box trailer (no one would really accept anything less, as that's mostly what's hauled and the aerodynamic aspect is a huge component in range and efficiency testing)

as soon as the Tesla sleeper cab is revealed & its weights freightliner is going to poop its pants, the real thing holding Tesla back is the 1 MW chargers ,if they were to install multiple charger(s) @ 200 mile SENSIBLE locations,it would bye,bye to kenworth freightliner & Volvo as fast as Tesla could build them, roll on Tesla semi :) :)

[@jlg8689]

Tesla Semi qualifies Inflation Reduction Act EV credits?

[@inclusivelove5165]

What competition?

[@qkktech]

Tesla semi uses about 660Kwh to overcome rolling drag in 500mile and 177kwh to overcom air drag and other components. With typical load to overcome rolling drag is 480kwh.and that gives typical range over 600miles. When charging then charging speed starts to dropfast after 80% and it is not recomended so Tesla semi practical range with typical load is also 500 miles that means 80% charged rande with typical load. About cabin i dont like idea sitting in the middle it is very very hard to pass obstacle or slov vehicle when you cant see incoming traffic. I have used car that has driving wheel on wrong side and it is simply dangerous. I hope tesla has some sort of camera or radar to overcome that hudge problem.

[@savvysurveyor5318]

Watch the videos which show the cameras in use, much safer and you get the perceivable benefit of avoiding obstacles on both sides, as obstacles are never just on the drivers side 👍🏽
