re: Tesla Semi could be ‘the biggest catalyst in trucking in decades’

According to Tesla's site, it takes almost 6 hours to charge for a 300 mile range using a 90 amp/240V charger. that will chew through some power.
Im assuming they would be using 440, 480 or 600V service and supply to the chargers to reduce amp draw considering how many trucks could be lining up at the same time.

Or what about transitional incrementalism - the idea that the entire system of land-based transportation will not all transition to an autonomous state at the flip of a switch, thus exponentially increasing variables related to safety.

Im guessing triple redundancy might be the only solution. As reliable as solid state can be, especially potted and high-quality Japanese components, even one accident will have the naysayers slamming the panic button down repeatedly just like they do now for low volume recalls like Ford Exploders and Toyota Runaways.

Another major issue is weight restrictions on roads. There is a reason every state has weigh stations and weight restrictions on trucks. As long as there have been trucks, there's been the issue of trying to limit the overall weight of the truck itself so it can haul that much more freight while staying under legal weight restrictions.
If you go adding electric trucks to the market, you have to factor in the weight of the batteries an electric truck would require to make it an economically feesable alternative to a diesel powered truck. The heavier the batteries, the less freight that truck could haul.

I would think at least that but I was pointing out the timeframe and the power draw just for a small car as a comparison to what a truck might be.

Trucking companies won't give a damn about unions when they realize how much money they will save by using robots. Unions will be obsolete.

I just don't see them saving much when you factor in things like;
1. Electricity bills
2. Battery replacement and disposal
3. Lower productivity levels due to electric trucks being unable to haul as much freight as current trucks.

Still needs a driver to offload or load depending on cargo.
I don't see trucks driving around the country without a human in them for a while.
However, what would refineries making diesel switch to if this is the norm by 2030?

Exactly. The OT is full of a bunch of old Luddites.

Not all trucks operate between nice, neat terminals and operate on nice, smooth interstates (not that most interstates even qualify as smooth). One prime example is lowboy trucks. They have to unload their loads in places like lumber yards, rail yards, job sites, quarries, or mines.
So they hire a last mile driver and pay 10% of what they pay currently

Will these trucks be able to convoy in order to run interference for Smokey and the Bandit? If not, send 'em back to the drawing board.

It's a Tesla, right?
Let's shoot for 2030 then.
Musk always sets "aggressive" timelines, yes, but that's the reason the man has managed to start a car company (no small feat) AND a motherfricking rocketship company in just the last 15 years. His efforts have managed to produce several all-electric road vehicles, and he's sent a bunch of stuff to outer-fricking-space.
In 15 years.
No way it takes him that long to produce a truck.

Wonder how many thousands of dollars those batteries will cost? To me that statement is akin to Ford saying you can buy a new F150 for $35,000 if you buy the engine separately.
It's more like Ford saying you can buy a new F150 for $35,000 if you buy the gasoline separately.

Don't you know when you get gubment subsidy you can ignore physics snd economic reality.
And the real economic reality is we have a few million truck drivers in this country who need to start learning some new skills.

I thought the same thing. I'm sure the river pilots will try to get in on that action.

quote:That's not confirmed, but if so that covers a lot of the need. Plus there are other options besides charging.. batteries could be swapped, trailers could be swapped..
Thats the problem. These are gonna have to be charged about every 300 miles or so.

quote:Tesla already demonstrated this tech a few years ago. LINK
This is a major hurdle for the technology. What they should be doing is collaborating on making their batteries easily replaceable to instead of recharging stations they (both semis and consumer vehicles) could just have the batteries swapped out for fully-charged ones. Ideally it should take no longer than filling up a tank of gas on your average consumer vehicle.

quote:Electric motors are MUCH better suited to this than ICE ones. Also, for every incline there is a decline, and regenerative braking can put a little juice back in the batteries.
Now imagine the power an electric truck would need to pull even it's own weight (not to mention an actual load) up some of the inclines out west.

So you think there would be little cost associated with hauling the load before it had to be passed off to a human? Pray tell how many batteries would it take to haul something like this?

I just find it odd that this technology has the potential to make your trip in a car so much safer, and it'll certainly get to the point very soon where anyone would or should logically trust the car more than they trust other drivers on the road who can't drive for shite. But like you said, 1 car malfunction and everyone will lose their minds, despite the thousands upon thousands that could potentially be saved by it.
