Modules run high weight over some pretty shaky bridges. I think 45,000 lbs is about average for a class A load. Unless you are hauling car batteries, or heavy equipment on a specialized trailer, 80K is unusual. Michigan being the home of the auto industry has some unusual requirements, and out west where there is still mining we have some massive payloads too.

Speaking as a truck driver with over 10 years of experience, you can reasonably expect to spend about $34,000 per year on fuel assuming you're averaging 2500 miles per week, and in a truck that average is 10.1 miles to the gallon which is very good fuel economy. That being said the range estimates on these vehicles are extremely limiting in my humble opinion with diesel fuel I expect to get approximately 700 to 800 miles on each fill up. There would need to be very serious changes to improve structure to make this a viable solution particularly for warehouses and loading docks where trucks will spend an hour to two hours sitting and getting unloaded. And don't quote the 30-minute break rule at me because I can tell you from experience it is very rare that you get to choose where to take your 30 minute break. Personally I think Tesla dropped the ball on this in putting its Research into semi trucks, a much better investment would be short-range buses such as city transportation and school buses where the shorter-range and lighter weight of the cargo will offset the disadvantages of battery power.

Sure, some OTR trucking and longer distance trucking will adopt this, but it will not be the primary market.

final mile truckers may adopt it as they will be able to more easily stop and charge their vehicles (i rarely did more than 100 miles a day when driving for jb hunt, most of my time was spent unloading or managing disasters caused by improper warehouse pallet stacking) I don't think the 30 minute break will matter as much for the truck as you will have to charge longer than 30 minutes to get your full battery back, it would be done overnight while in the sleeper berth, however i don't think that 500 mile range or even 600 mile range will be enough to get between the few charging stations that exist and when we do start seeing charging stations at fuel stops they will likely be charging that electricity at a rate comparable to the fuel you would otherwise be buying thus offsetting their loss and your profit from using an EV fuel stops are greedy and charge high because they know we have no option other than to buy, and because of this i have no faith in an electric truck being viable without infrastructure overhaul. couple that with our companies barely being able to run a qualcomm or other ELD, a fully electric truck would be impossible for them to understand and maintain

I was a mechanical engineer before the recession and now I’m a truck driver. I have unique personal experience on this subject. Weather will be this trucks down fall. Batteries don’t work as good when it’s cold outside. Also my current truck has a 2000+ mile range and I need every bit of it to do over the road driving. There are plenty of places a battery powered truck will never be able to go.I have personally stayed at shippers for over 24 hours picking up a load in the middle of nowhere in the freezing cold. Batteries can’t handle that environment. Driving 60 miles an hour is downright dangerous. A very slow truck is governed at 62 and those create havoc on the road. The trucking industry is brutal and it will find the flaws wherever they are. That is the reason trucks have not changed much over the years. Not trying to hate on the people who have pre orders in... get your money back if you can and wait till they perfect it first. Don’t be a guinea pig for this experiment.

@@twt3716 Knight-Time equates his experience with cross continental and multi-day trips with a truck that's specifically been designed for local deliveries from distribution centers through metro areas. You know, places where you're not waiting at the port 24 hours for containers from a ship. Pepsi is Tesla's first truck customer and I'd argue that if you were to spend 24 hours parked at their distribution facility, you'd be fired. Tesla are after the day market which is mostly taken by International. One thing that makes me question his involvement in the trade as a trucker is his 2,000 mile range. Most tractors have 2 tanks, each upto 150 gallons. Using the 95% rule, you never top them off but you also never get the chance to run them completely either because the fuel system doesn't go to the bottom of the tank. It's impossible to get 300 gallons out of two 150 gallon tanks, besides you don't want the stuff that accumulates in the bottom of the tank after a few years. So you're looking at ~110 gallons per tank or 220 gallons with two tanks and that's a push because most won't take them below 1/4 of a tank remaining because it's a pain to prime the system once there is air in it. 220 gallons of diesel will typically get you 7 mpg IF you have a modern truck so that's 1,500 miles max on a good day with not too many hills. With my time at Chevron, their development dept responsible to top of the line oils like Chevron Delo said that most were averaging closer to 6 mpg, giving a useable range of just over 1,300 miles. This was based on their own fleet of trucks and working with Freightliner. If you wanted to be "that guy" that fully filled his tanks and risked running a vapor then close to 2,000 is theoretically possible but the fact is that most won't risk a $300+ bill to have someone come out to put some fuel in the tank, drop the filters, prime the system whilst leaving you at the side of the road feeling like a fool. His misaimed rants are exactly the same as what people were saying 12 years ago about the Tesla Model S - that they'll never catch on, the industry would never accept them, people wouldn't buy them because of range anxiety, chargers will never be able to charge fast enough. The Model 3 and Y are some of the most popular cars today. The Model S still sells well when stacked against it's gasoline competitors and the soon to be released Roadster with 600 mile range and 0 to 60 setting new standards, even for the base model, it's hard to argue the progress being made. Then again, NASA tried for decades to land a rocket and make it reusable but instead embarked on the $196 billion Space Shuttle program. Musks' Space X achieved the ability to land a rocket in years, not decades. Using tech from the Tesla cars and Space X, Tesla has promised Pepsi their trucks will not leave them stranded at the side of the road for at least 1,000,000 miles. They've proven successful in an area where you can't afford a single f**k up - space and are applying lessons learn with system redundancy. Multiple battery banks able to power 4 independant motors. Only 2 are required to haul a 80,000lb load. He also seems to forget that many states have 55mph speed limits for trucks with the majority at 65. So many criticisms in his post that just don't apply to a truck that has a specific use case. Pepsi's first plant to use the trucks are the Frito Lay facility near Modesto - so 55 mph up and down I-5 and Hwy 99 moving potato chips and spuds. There are still people around that are old enough to remember that it wasn't all plain sailing for diesel powered tractor trailers either. With over 100 years of development to get where they are today, it'd be a bit short sighted to say the least to expect the first all electric semi to do everything at the first try but then again, people always seem to forget about the history, development and money spent getting where we are today. If someone would have said 12 years ago that a 4000+lb electric car could do over 400 miles on a single charge, carry the family in comfort and do 0 to 60 in under 2 seconds and embarrass all the hyper-cars out there, you would have been laughed out of town and told to up your crazy medication. I'm surprised that the next step wasn't a hybrid diesel electric, just like with trains. Diesels aren't as efficient as electric but keep them at a specified rpm range and they become a useful generator. Just like with cars, development will take time. Maybe cross continental will never be a thing, maybe it'll be common place in 10 years with new battery tech. Who knows. If you don't try and build it, it will never happen. If we would have taken that approach to things we wouldn't have an internet to post on and would be living in an age where I'd have to go out and club small animals to provide for dinner, ya know.

The most important thing Musk fails to address, LOAD CAPACITY, which for an electric truck will be abysmal. The batteries alone will weigh 1/3 of the maximum 36 ton limit, so you'd be lucky to have a load capacity of 6 tons for the actual cargo, less than a third of a conventional truck. Musk is nothing more than a salesman.

My company actually has electric semis in testing and Tesla’s on order . So far 125 miles per charge and 5 hours to charge even if the Tesla is 50 percent better it’s completely unusable. Local trucks run two shifts day and night 800 to 1000 miles a day and often need to drive a pto to unload product. Long haul trucks will run 600 to 1200 miles a day with either solo or team drivers to make things worse there is a crippling lack of parking which means you will not be able to build enough charging spaces without a lot of concessions being made on building new truckstops half the time drivers just end up sleeping in their customers lots . And if you think those same customers who get upset if pressure is put on them to unload in a timely manner will put up charging stations for random trucks your mistaken . Currently diesel trucks like the cascadia equipped with the 120 gallon tanks will go 1920 miles on a filling not 900 . Energy density will have to increase dramatically and there will have to be major infrastructure investments to have electric semis . And even then they won’t be able to be used in several vital applications that require the use of a pto they will be completely unworkable for agriculture applications for quite some time .

Who said that plutonium cost $2,500,000 per pound?, thats bullshit, let me explain it the cost of that is assumed the value of 1KG of plutonium if you sell every kWh at the same price that cost a kWh of oil, or coal, so divide the cost of 1 kg of oil by the energy density and then multiply the kWh's to the energy desnsity that a kg of plutonium releases by fission, that is an staggering 23GWh, or 23,000,000kWh the energy density shown in the table is the energy that Plutonium 238 releases by it's decay heat, Pu-238 is almost exclusevely used in satelites, and space probes. 1kG of 5% enriched Uranium (5%Uranium-235) costs 800$, but Plutonium? plutonium is free, is created when U-238 gets a neutron.

Khoa Do Not cheaper. A website said:The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29-$56 per MWh. Nuclear energy costs between $112 and $189. But technically, nuclear power can be an energy source that is better for the environment, but it’s non renewable energy, so eventually we’ll run out. Nuclear stations needed to produce nuclear power can also be dangerous, like what happened with the nuclear explosion. So in my opinion, no, nuclear propulsion is not the future(except maybe in spacecraft).

Yep kinda sad the batteries themselves will cost more than a traditional one. Also cost not shown here is how many time you'll need to replace those batteries because of battery life being reduced as the batteries age. Let me tell you as an experience diesel enthusiast (I love bio-fuel as it's carbon neutral). Trying to remove my bias. Those trucks, especially the older ones with older transmissions and engines that are inefficient and very dirty can be cheaply rebuilt from the ground up, engine and all. She'll usually last you around 350,000 miles or more before another rebuild. You can easily rebuild a semi truck engine and transmission from before 2000 for less than 10K USD. And those engines can be rebuilt almost indefinitely. They are heavy, durable, cheap and powerful. I think Elon should try bio-fuel instead. It's cleaner and carbon neutral. Electric cars maybe. But I saw this coming years ago. I don't think electric trucks are a viable alternative. Pure biofuel is. Besides electric trucks are no cleaner if your fuel source is natural gas or coal. Renewables like solar and wind can't deliver, no matter how much gov subsides you give them. Those companies love you're tax dollars. Seriously we need new nuclear plants more than ever.

500K? Miles right? My people carrier is really struggling to get past 80K. The competitiveness of the Tesla truck must depend on the battery life. ie is it 10years or 100,000 miles? Battery lifespan is usually dictated by number of charge cycles, so the mileage will dictate this. If you need to change the battery 4 times in the life of the truck then that is a huge extra maintenance cost.

Wow. Like everyone who replied to my comment is a truck driver. That’s kinda interesting. Ive been watching Tesla as a company for a long time, and I love having conversations about it, so I’ll try to address some of the things you guys have been saying. I haven’t heard anything about the batteries only lasting 10 years. That doesn’t sound like Tesla. But even if that is true, battery density is quickly improving, and batterie cost is really going down (mostly thanks to Tesla) so replacing a batterie after 10 years probably won’t me that bad, and you probably won’t need to replace it again. I guess I didn’t hear the part where he talked about the regenerative breaking, but that greatly reduces the size of the batterie needed. As far as maintenance, I’m referring mainly to the fact that the Tesla trucks don’t need to have their break pads replaced for 1,000,000 miles (again because of regenerative breaking) and just basic maintenance that gas vehicles require that all Tesla vehicles don’t. And even if those repairs can be done at a scale that they are cheep to do, not doing them at all is still a lot cheaper.

The Netherlands is even more dense and there it is 50 tonnes.

Everyone asking if he took into account the regenerative braking needs to rewatch 3:45. Also what goes up must come down. Sure you gain some power back from braking but you need to climb that hill to go down the other side or you need to accelerate to later deccelerate . Even if you started at the top of a hill, to make a around trip you got to climb it to get back. Nothing is free even if it was a real slow up grad before a steep down, it still uses extra energy over time. You may only gain back 10% of the power it took to climb or accelerate and im sure Musk took that 10% into account for the range estimate. I bet if you where to drive and not stop or go down hills youd fall short of target range. But I cant wait to see these trucks on the road. Seriously!

Very nice summary of facts and cool website!! I am unsure about your drag calculation: I think its v^2 not 3..

My understanding was that the Tesla truck was being marketed as a lighter truck which allows for greater payload capacity. The number I remember seeing was something like 6,000 pounds less which in turn can be turned into cargo. Even so not all cargos are at maximum weight, a lot of loads are limited by space. A load of cans going to the bottling plant only weighs about 6,000 pounds

Future Hindsight: 1. Electric motors are not "maintenance free." My father made a living repairing crane motors (electric) that blew up due to too much stress. My computer did the same thing. Think of semis like crane motors or computer power packs. They will be taking a beating. 2. There will be NO charging at the shippers. Most van (box) truck operations are dropping one trailer and picking up another. Flatbeds in mills are usually allowed about 15 minutes to chain and leave (some mills give you less time) because the next truck needs to get on the dock so the crane can load them. Most commercial shippers (like grocery and department stores) don't even want you on the property when you run out of hours of service, let alone to recharge. These are just some of the issues that need to be dealt with for electric to succeed.

I would imagine they are very easy to fix, the battery pack is a bunch of little batteries to replace and the motors are pretty much just replaceable, they are much less complicated than an engine.

for your information an automatic freightliner cascadia can maintain about 7.3 mpg with 2x100 gallon tanks so your 900 miles range is a bit like saying a truck spends all its time in town.

Now you add an overhead wire arrangement like they have for urban transport and you have the solution to getting trucks through mountain ranges; grid power for going up the hill, regenerative braking going down the hill.

The problem is people think as cynics, not entrepreneurs - they contend that an electric truck would need to be able to do everything a regular truck can to be able to sell, when that isn't the case - it only has to be preferable in some situations and then companies that need that will buy them. A perfect example is manufacturers, especially large scale ones. These are companies that have trucks going from their manufacturing plants to distribution centres, these are known distances and regular frequency trips meaning that the distance and payload can be anticipated and recharging planned. These sorts of companies (beverage manufacturers etc) have pre-ordered many of these.

This is the best science documentary channel on the internet in 2020

I'm going to stick my neck out here but I'm pretty confident in what I'm about to say: That equation is wrong. The "1/2" in the inertia term shouldn't be there. If it's derived from Energy = Force x Distance and Force = Mass x Acceleration then it should be Energy = Mass x Acceleration x Distance then multiplied by the efficiency terms after it. I see no reason to include the half or am I missing something. Also there's a velocity term common to all the parts of the equation so why not cancel it out and simplify the whole thing?

The 1/2 is for regenerative braking and to account for acceleration and deceleration. you recover most of the inertial energy you lost by accelerating through regeneration but there's a round trip efficiency to account for losses of energy through the powertrain while spending and regenerating the energy. So that's why it exists. And the velocity in the drag term is rms velocity also cancelling it would make it simpler but harder to explain how you are accounting for each of the forces, hence it exists. Thank you for listening but no thanks for not reading what the equation actually means.

I don't know if you noticed, but Mercedes Benz has already started production of their eTruck, which is based on a standard 16 Tonne Truck, but the German authorities have agreed to keep it that way motorway toll wise, even though the truck weighs 17 Tonnes in its 4 Battery Pack 400km range config.

The batteries take up so much weight payload that it takes twice as many trips to haul ass. None of Elon's yes-men had the nerve to tell him that's a fatal flaw in his whole pitch.

It doesn't need to be that complicated. You need about 100kw to move a very aerodynamic truck down the road at highway speeds. 11 hour shift needs about 1100kwh. Your numbers are way off on the weight and power required 1/2 the load will still require about 80% of the energy. 5kg(5kg per kw of battery pack) x 1100 is about 12000lbs for the battery pack. Weight saved by placing the motor closer to the drive wheels and simpler transmission will be about equal to the motor weight. Weight saved on engine and fuel will be around 4000lbs for a loss of around 8000lbs or 20% typical capacity. For many loads, you are fine with a 40ft box holding 30,000lbs, so it is quite doable. Electricity is about 1/4 the cost of diesel per kwh, so at $3 per gallon and 8mpg(really aero truck on flat highway), you save about $.28 per mile. 150,000 miles a yearly saves just over $40k in fuel. With batteries at $300kw, you have a $300k battery pack that needs to last 7 years to break even(assuming 0% interest). With the money saved on 40qt oil changes, Apu and other related items, we are close to where an electric truck starts to make sense. In 10 years it will be the more efficient option for sure.

Jimmy's Tractor Your battery calcs are off. Current 2170 battery cells achieve 350 watt hours per kg. That means a 1000kw hour battery is about 6300 lbs. That is *VERY* competitve. And the cost of those cells are now far less with the automation Tesla has built at the Nevada plant. We know the rig costs $150k max for the entire thing. There's nowhere close to $300k in batteries. Anyway - I agree that things used to be closer to what you are presenting, but the data has changed dramatically between 2010 and 2017. Google the 2170 battery cell for more specs - you can calc the details from there. And Tesla's magic on longevity is their incredible battery management software. It carefully controls charge and discharge rates and that's honestly where the money is. That's also what will allow them to get 10 to 15 years of useful battery life as well. Fact check me here but I believe this to be accurate.

Electric doesn't necessarily mean "green" depends on the fuel used to create the electricity used to charge the batteries. How does an electric semi compare in performance and green house gas reductions to a conventional truck powered with bio diesel?

Do you think on the go reacharge options for the batteries would help increase the range while decreasing the battery weight
