Why not electric tractors?

[ReinyDays]

Oh....
Hybrid Tractor trailer rigs can haul an extra 40% more weight than an EV tractor trailer rig because of the weight allowance WHILE experiencing 20% fuel savings at the same time.

Drive by wire systems are awesome. Each tire gets a motor and torque. For 18 wheels that's a minimum of 540 Horsepower all wheel drive with just 30 horse motors on each wheel. (They can be stronger than that....40's and 50's are not out of range)

And each wheel is independent of the others if one loses traction or increases traction over the others.

Edison Motors has several prototypes already looking at full production with standardized bolts, lights, and all the rest.

But they are hybrids. And most logistics (trucking freight) companies would kill for 20% fuel cost savings. The increased load weight is just another bonus. Hybrid tractor trailers weigh LESS than EVs. But they still get the extra weight allowances as a full EV truck does.

Ag is seriously looking at these as they tend to run overloaded as it is with field crops like grains. Hopper bottom trailers have a bad tendency to get overloaded by farmers and then have issues getting out of the fields. (Just normal stuff)

Hybrid trucks aren't much different from train engines . Diesel motors that generates electricity that then turns motors.

You must be confused about the trucking industry ... these trucks are already carrying their maximum legal weight ... trucks today can carry three times the their legal weight ... except it's illegal ... duh ... ever heard of "weighmasters" ...

Where do you fit eight 30 hp motors under the rear carriage? ...

I drove Tractors for a few years see firsthand that they require a LOT of power to get work done, never will consider EV tractor as a viable choice.

There are already many heavy duty EV heavy haulers on the highways. As with the advent of 500 watts per Kg batteries, there will be many more. And there will be batteries that exceed even the 500 watts per Kg by 2030.

Yes, and the weight of the batteries comes off the payload that the truck can carry. So you transport less goods for the same, if not for more money. In addition, the journey times are longer due to recharging. So all on all, the cost of those goods increase due to the haulage charges.

We can do hybrid trucks....where hydrocarbon fuels power a generator.

Lots of maintenance but feasible. If hybrids got the same research dollars as all EV....they could have solved the maintenance issues. But they didn't and wasted trillions of dollars of taxpayer money.

Would the reduced required diesel offset the weight of the electric hybrid side (battery, motor etc..)

Absolutely, in fact hybrids come in underweight from standard diesel Tractors with roughly 20% savings in fuel costs.

And in 1900, most farmers would never consider a diesel or gas powered tractor to replace their steam driven tractor or there horses. LOL Technology changes, and there are a bunch of much more powerful batteries being developed as we post.

And as the new battery chemistries are put into production, EV trucks will come in much lighter than diesels or hybrids, with far less maintenance and longer useful lifespans. The batteries are going to do for fossil fuel transportation what the diesel and gas engines did for the horse and steam engines.

Going to diesel from steam is going up in technology. Going from diesel to electric is going down in technology.

Not a long video trying to sell you on the concept....

Ok, thanks -

Funny looking farm tractor?

They can't yet....
The "better" batteries have been promised for decades now. Still nothing to show for it.

What I'm showing is a product ready for production with MINOR issues to work out.
Not a laboratory battery....not something that has massive production issues or requires exotic materials. But common products put together and technology that is already in use which can reduce petroleum use by 20% on a commercial use product.

The truck in the above video has a "Drive by wire" setup with transmissions and motors on each axle. Also each axle can generate power as well when coasting. (Depending on demand)

The Trillions of dollars wasted on all EV was a waste of money given to ultra wealthy people.

We can have hybrids tomorrow.

The only issues are maintenance levels are high and some tweaking with motor controls. These things can be overcome by some engineers hired with those goals in mind. NOT DIFFICULT ENGINEERING TO ACCOMPLISH.

So....

Let's play fantasy land....let's say tomorrow EVs are mandated in America and everyone switched out their ICE vehicles for EVs.

Peak petroleum usage is still 50 years away.

Meaning that we will need an increasing petroleum supply for the next 50 years anyway.

Do you want real solutions or do you want to continue to fantasize about technology promised but does not exist?

It's a tractor/trailer tractor....made for hauling logs, agricultural products, and occasionally hot tubs.

Farm tractor engines are not much different. They don't take road diesel but instead farm diesel. That's the only difference. Transmissions are different but essentially the same engine.

Which I get it, it's a major part of the difference between the two. But the EV crowd is targeting farmers because of the numbers game. There are so few farmers anymore that they don't have much of a voice. More are going bankrupt every year...being squeezed out by those supposedly wanting to help them. (Farm Credit, Associations and etc)

Cattlemen's association charges $10/head fees....pork producers are next with a massive increase in fees. Farm Credit already squeezed out the small chicken farmers.

Cotton, wheat, soybeans, corn and oats are next.

Small farmers are the backbone the big Ag lives on. They kill them off and there won't be any farming anymore.

Hybrids work by recovering the energy from inertia ... when the tractor/trailer rig is rolling down the freeway at 65 mph for 11 solid hours, it's just the piston motor running ... when the rig goes to brake, that's when the generator kicks in, recovering the energy ... the generator isn't connected to the diesel fuel source, just the axles ... big rigs aren't braking much on the Interstate ...

Truth be told ... these big rigs are fine the way they are ... they produce a manageable amount of carbon per ton of cargo ... railroads are even better ... the problem is passenger vehicles ... running a 3 ton coupe with no cargo, just one passenger, 5 minutes of warm up just to drive 30 seconds to the corner market for an ice cream bar ... something better done with a golf cart and lead/acid batteries ...

You have no idea what large Tractors require for power as it is greater than a E-Truck which the Ford F250 series failed badly.

Battery Technology isn't improving that much certainly not enough to justify a new set of environmental problems it generates and they suck as storage mediums.

When I used to drive dump truck with manual transmission I would downshift to slow down than use the brakes when I have a big load because it saves the brakes from excessive wear.

In my own car I just coast to a much lower speed before using the brakes to stop saving fuel and brakes which is fixed every 8-10 years or so, the city Truck I drove for about 11 years had just one brake maintenance despite my pulling trailer with Tractor, Trencher or huge mowers because I would coast down the speed first before using the brakes.
