CA Mandates all trucks must be electric beginning in 2024

Maybe more windmill farms will be filling the skyline of California in the future

Maybe more cows will have fart bags on their ass as well. Catch that methane and use it to power electric generation. LMAO!!

Yes, energy storage is the current issue, liquid fuels are better for energy storage than batteries
I don't think that will ever change, batteries will get better, but will never catch liquid fuels in energy potential and weight

No i just figured since an average tractor is 30 now add another 20 on top of that.

Seeing as how an average tesla sedan is like 2 k heavier then a similar gas. (6k vs 4k), and then add more for more range.

I couldn't quickly find anything resembling official numbers for the battery packs, but there were some credible guesses in the 12-15k pound weight range. Given the reduction in weight of the powerplant itself, a lot of that is offset. Looked like closer to a 4-5 thousand pound difference in total capacity.

You know how heavy an electric motor would be to replace a diesel?

Thats alot of whinding....

 

[fastpakr]

Do you?

 

[rusty ol ranger]

Do you?

No. But i cant imagine it being significantly lighter then a diesel.

Dry the ISX 15 is aroud 3000lbs.

Cant find the weight of a big electric motor.

I suppose you could take the trans out of the equation....but still...i dont see it saving much, if any weight.

 

[RonD]

There would be 3 electric motors on a semi tractor
One for each axle, yes front axle as well, so AWD
There may be a way to "free wheel" 2 of the axles if there was no trailer attached, it didn't save much on MPG for our Rangers with unlocked front hubs

I don't think the "in the wheel" motors would work for this application, maybe some day

But yes the battery pack weight to run these would be way more than the weight of diesel engine and transmission

If doing a hybrid diesel/electric, no batteries, it would add more weight but I don't think it would be that much more and MPG would be much better
Like highway MPG but in city driving since RPM is steady

AWD would be nice....

But i really wouldnt wanna give up my diesel

Really depends on how it is built.

Are they sticking a big motor in nose? 4 or 6 hub motors? Something in between? And you have to route significant cables to feed whatever you do.

Transmission optional...

No idea how it would compare/hold up but here is a 300hp electric motor that weighs a touch under 3000lbs. A little soft on hp but electric doesn't play fair with torque either. Probably not the most cutting edge motor out there for such a thing either.

EM44304TS-4 BALDOR 300HP MOTOR

BALDOR EM44304TS-4, 300HP Three Phase Super-E Motor is designed for use with pumps, compressors, fans, conveyors, machine tools and other general purpose three phase applications.

300hp? Thats cute. This ISX is 500.

I know the thing about electric torque...blah blah blah but i still bet this ol cummins in low would give it a fight assuming traction was equal.

But you gotta think too...thats 3000lbs just in motor...add in batteries too...theres no way around the fact an electric truck is going to be much heavier then a diesel, anf really, less practical.

 

[stmitch]

You subtract the weight of the diesel engine, trans, differentials and fuel tanks and replace them with batteries and motors (either one per axle or one per wheel). I suppose frames could be redesigned to acommodate twisting in the opposite direction rather than longitudinally and that could alter the weight of the chassis some too but that would take some FEA software.

This Tesla Semi was pictured while testing, with the driver claiming around 75k gross:

That's 9 ecology blocks by my count which weigh about 4k each. A 49ft flatbed (presumably steel) is around 13k.
So 75k weight - 36k load - 13k trailer = 26k for the cab as a SWAG. I don't see a sleeper on that so I'm guessing that's a day cab?

Google tells me that an average diesel day cab weighs about 16k. More like 20k for sleeper trucks. Plus fuel, driver, etc. So if those numbers are accurate, the electrical stuff probably adds 5-10k in weight over a diesel powertrain.

It is a caveman crude industrial motor that is made to be bolted on the floor too. I am sure they could save weight if weight mattered... and they don't need a transmission.

They make them with more power but rarely list the weight, 300hp was getting in the ballpark.

But yeah, I think an electric truck is probably going to be heavier than a diesel.

California isn't flat, either. That's one of the issues. It is a little different proposition going over the mountains with electric, than diesel. If they really did try to get rid of all diesel OTR trucks, it will spawn a huge amount of truck stops at the state border, greatly increase train freight traffic (thus slowing down delivery), and possibly impact port traffic from overseas.

The railroads could electrify a LOT easier than the trucking industry, at least so they could get freight over the border into neighboring states.

Oh and don't forget the additional wear and tear on the roads. More trucks, and heavier, to move the same amount of weight.

 

[MikeG]

I can see it now - when the truck runs out of juice, hoist sails if the wind is favorable..... LOL.....

 

[RonD]

Well if the batteries were recharged with wind power it would be the same thing

And you could always carry a portable generator, lol
