Electric trucks - how's that going to work?

It’s clear that hydrogen fuelled ICE is doable just obviously not liked by the ICE haters.

Historic racing vehicles still take to the track, old trucks still go to rallies.
In the future V12 Jags will be on the move. They won`t be burning gallons of leaded petrol in the commute queue outside the school gates, but they will still be around.
Will anyone build new ones for practical everyday transport?
Nah, but lookit this:

There are still loads of Jag engines around so no need to remanufacture them from scratch, but it is do-able. And if legislation means petrol is replaced by hydrogen…so be it.

Ah no come on be sensible, it doesn’t fit Carryfasts ‘everything is going to s**t’ narrative therefore he won’t believe it. Chaps like that hinge their whole personality on being against things, being against ‘the sheep’, don’t go expecting to talk sense and have him believe it! So be kind, at least throw a single word or phrase in there he can create a whole post/personality around- ALL HAIL CHINA! AND THE WONDER OF CHINESE ELECTRIC CARS. There, that should set him off.

The Tesla ‘semi’ truck -

youtu.be/Ael2nTAraXs

Things I think are so obvious I can’t believe nobody has thought of them before-

  1. Gorrila glass for windscreens.
    Ok, I know it didn’t work for the off road Tesla but it’s a good idea

  2. Central driving position
    No blind side reversing! Cheaper production without LHD/RHD production

  3. The driver technology
    If it’s anything like the Tesla S (and they reckon it’ll be better!) Then I truly can’t wait to have a go in a ‘semi’

  4. 80% charge within 30 minutes of plugging in.

Things that leave a bit to think about -

  1. Installing enough charge points nationwide that a small firm charge up.

  2. Claimed range 300 or 500 miles
    I am highly sceptical of this figure. The video gives the impression this is motorway miles (which I presume is fine for the USA) most of my work is spent on A roads, how would that affect range?

  3. Claimed figures/running costs
    As it’s a prototype vehicle I’m guessing it hasn’t passed official now/emissions/NCAP etc etc… could we be looking at figures being heavily revised or a new Volkswagen gate?
    Company claims and official figures can be very different.

  4. “Just charge up on the bay”
    Work I’ve done since October has been FedEx, Amazon, Palletforce and palletways. All of them were drop and swap, no waiting on the bay, no chilly downtime. Drop it there…move!
    Granted, they do have a tractor holding bay but it’s so busy I can’t see how they’d cope if people were sitting around waiting to charge.

My own queries -

Fridges - do they run off the semi battery or their own battery or diesel? Has that been included in range figures?

Semi’s and trailers pv cells?
Why aren’t manufacturers installing solar panels on trailers/roof and semi?

Here’s a concept motorhome in conjunction with Iveco -

Like I say, not a hater at all, just very curious how it’s going to pan out in such a tight timeframe

AND…

Here’s an idea for Elon, instead of a centre mounted driver seat, put it on a motor so the driver can move left or right or centre.

Firstly unlike Mercedes and BMW Jaguar’s classic parts provision is a joke.
Plenty of knackered engines isn’t much use when you need non existent new parts at a mass production price to make a good rebuilt one.

The final paragraph is a contradiction.So we just need to convert to hydrogen fuelled ICE what’s the problem.

In addition to the fact that Climate Change denial should be just as much of a choice as which religion or no religion anyone chooses to follow.
If you want an electric toy at an ICE price refuelled at 18p per kwh + road fuel duty + the cost and weight of batteries that’s your choice.
The truth is no one is capping any oil and gas wells anytime soon.This is all about who burns it not we musn’t burn it.
Those like Sturgeon will still be flogging it to her preferred mates while we are told to drive electric toys and pay for the privilege.

So you agree that hydrogen fuelled ICE is doable for classics and for new vehicles ?.
Which makes the whole EV argument moot.
While you don’t seriously think that anyone really bought a V12 Jag or BMW for local commuting and shopping use. :unamused:

  1. Central driving position
    No blind side reversing! Cheaper production without LHD/RHD production

Unless the seat slides across or you have a 3ft long neck every reverse is a blind side, though i would have though self maneuvering would be installed long before these things are unleashed, should be fun to watch given how efficent the self driving self braking aspect in when the cars have been know to smash into stationary objects at high speed.

John Cadogon reckons electric Jesus’ company is heading for failure, watch this space.

The driver assist tech that Elon was so proud of is standard in European trucks already. And we all know how well it works (sometimes).

the project is well behind schedule, there’s no explanation as to where the power to recharge the batteries in such short order is coming from and there’s a deafening silence over weight and payload (which is dependent upon battery technology.

Over 100 years ago, electric trucks were just around the corner…waiting on a charging/battery network.

The advantages and problem issues are still the same.

They do have a gearbox, diff, alternator, and clutch of sorts.

Actually they don’t.

One of the biggest issues with EVs has been tyre wear due to the fact the maximum torque is applied from 1RPM. They don’t need a clutch because these motors can turn extremely slowly and they can apply their full torque from 1RPM. The motors can rev up to silly speeds, and as I said they provide max torque from standstill so no need for a gearbox. Each driven wheel has it’s own motor so no need for a diff. The same motors that drive the vehicle also generate an electric current on over-run so no need for an alternator.

How does it transfer power from the motor to the wheels?

If it’s via a series of “gears” (cogged teeth) then that must be classed as a wearing part surely?

Hhhmmmm. Some strange stuff going on here.

I always thought that hybrids would be a good stepping stone on the way. Apparently Elon Musk disagrees with me! Cheek.
Here is a way, at least it was in 2019, (this idea uses a natural gas turbine) that it might have gone.

On the Mercedes etruck it’s direct drive: two motors, one driving each driven wheel.

Very clever design. Motors in the same axis as the driven wheels.
At approx 2min 20 it does show that the drive is reduced in the hubs. So, strictly, there is a gear train involved. But, a single reduction gear is surely much better than a gear box with multiple ratios, clutches, or fluid flywheels, bevel gears for 90deg turn, differentials, etc.
Maybe this is what Conor was thinking of in an earlier post somewhere?
It is not possible to design* a vehicle without mechanical bearings etc, so that appears (from here and now) to be as good as it gets.

  • OK, Mag-Lev, super-cooled zero resistance, etc. :smiley:

Electric motors also wear/burn out.

A gearbox is there to massively multiply the pathetic maximum torque output of an ICE and an electric motor just provides a similiar pathetic output just from almost zero rpm.
The difference is that an electric motor can spin up to silly rpm without throwing its toys out of the pram so doesn’t need the 1:1 or overdrive of a conventional gearbox to bring down engine rpm.
That’s a 9:1 Tesla gear reduction about the same as conventional ICE car 1st gear combined with final drive reduction.A truck needs massively more gear reduction than that.
So that Forth Bridge design will run a million miles who would have thought it.

Remind me what’s the purchase cost of a Tesla car + batteries.
Add to that electric charging at 18p per kwh + road fuel tax when a litre of diesel contains 10 kwh.

I wonder if lorries will skip batteries and go straight to hydrogen ,■■■■■■■ are on it as always :sunglasses:

A battery pack (maybe on the trailer) to recup energy as one brakes on descents, so extending refueling stops, plus hydrogen fuel cells?
Pure guess, but some hybrid form of hydrogen use is quite possible.

They’ve already put hydrogen to bed for planes because you need four times the volume/weight of hydroden to match kerosene. So practically and financially unviable, as it would be for trucks because of weight and tank size, and that’s before the production/infrastructure it requires (negating any carbon savings).

Funny that because ■■■■■■■ were only advertising last month with a hydrogen unit .

They’ve not given up on hydrogen, Daimler truck, Iveco, Volvo, OMV & Shell have formed a consortium called H2Accelerate and want to make a breakthrough for hydrogen powered trucks within a decade. electrive.com/2020/12/15/h2 … in-europe/

With electronics and electricity we had mobile phones and a separate battery pack, now we have something slightly bigger than a credit card and the computing power of the first NASA rocket, and it works on Tapatalk too.

Similar to the downsides of a narrow type conventional cab but much worse.
A proper central driving position is difficult enough with a rigid let alone an artic.

As far as I can see, they are two entirely different things. My first mobile phone battery was the size of a house brick ,now its a tiny wee thing. The battery in my car is a similar size and weight to the battery in my old Morris Minor from 1963. That tech hasnt moved on very much.

According to the Nissan website the Nissan Leaf takes 11.5 hours for a full charge of 239 miles in perfect conditions or 2 per day per charger. How will trucks charge in 1 hour

By using high power chargers. Those Nissan figures are for the low power domestic chargers and many of the publicly available chargers which are constrained by the same power supply limitations. The same website says that if you use one of the Chademo rapid chargers (available at around 8000 locations in UK and increasing almost daily) the same car can be taken from 20% charge to 80% in about an hour. Tesla’s Supercharger network is faster still (but only Tesla cars can use them…).

Won’t most people have home charges unless they want to spend 5 hours a week charging somewhere else

Yes, EV owners generally have home chargers, and they plug their cars in while they are parked up at home (or at work). This is fine for most owners’ daily usage patterns. If they go on a longer journey then they use the high power chargers available at MSAs and other filling stations to partially top-up while they stop for a whizz and a coffee. As electric lorries become more commonplace (which they almost certainly will) their usage/charging regimes will probably be along the same lines with full charges taking place during longer periods of inactivity, and partial top-ups as and when needed (and available) during the working day.

What about the problems of people running out of charge (cars I’m on about) and running cables up peoples drives and stealing a charge , iirc this has happened already in the USA , unfortunately for the snowflake who was doing the stealing the householder gave him an extra hole! … the snowflake phoned the police to complain as he had no option as he was out of charge !! . Funny though the cops told him it was no difference to stealing gas :fuelpump:

When you run out of fuel in a conventional vehicle, you can get a jerry-can of juice to put in. When you have a flat battery, you can get a jump from another vehicle or battery pack.

Ive seen a couple of vids where the car is recovered to a charging point. Is there any way (I wonder) to get a battery pack in a pick-up or whatever to give a boost at roadside? Or are totally flat batteries so rare as not to be worth such a set up? It does seem that there are lot of bells, whistles, flashing gizmos, and suggestions that the driver will not make his planned trip before it dies, but we all know those pilots who know better, dont we?
