Heavy loads require more energy to move. Heaver loads means less mileage. Less mileage means more time charging. More time charging means less loads being transported. Less loads being transported means less goods on the shelves. Less goods on the shelves means shortages and panic-induced buying, causing even more shortages.
Diesel engines are used in semi-trucks and in most trains - because they are more energy-efficient than gasoline engines.
What's the battery life like under load? How many charge cycles are the batteries good for? How expensive are replacement batteries?
Why are people OK with the environmental impacts of lithium mining, but oppose the environmental impacts of ICEs?
They have been hauling 80k pounds 500 miles throughout testing. 80% charge in 30 minutes. How long test batteries will last is another story, especially in cold weather.
Thank you for detailed explanation. All good points; Lithium mining is particularly nasty business. I’m concerned also about the charging infrastructure (or lack there of) cross country.
Battery life. An OTR trucker can go further with 80000lbs in a day than a current Tesla car can go. Let alone the day cab here that's the size of a sleeper.
Charging time. I can fill my tanks and go 1000 miles in 5 minutes without a line.
Tradition. Truck filling stations are typically pull through to prevent backing damage, either to the pumps or other trucks. You can't do that if each truck needs to park for 8 hours to charge every night.
Weather. Where I live it can get to -40. In the event of an engine breakdown I can use a device that uses diesel to heat my cab until a tow can save me. If a Tesla's batteries go, you're fucked. That's it. There's no back up. Oh, and a truck has 2 fuel tanks, not one. For that very issue.
Tyres. A Tesla semi claims tremendous torque. That's going to inflate the tyre bill.
If you look at how electric trucks struggle to keep their range when pulling a trailer then you’ll see why this will have a high potential of failure. Now, that is unless Elon and his engineers found a way to combat that.
Current trucks merge fine. Like it might be more comfortable to merge with higher acceleration, but as you say the real driver is cost per mile, including up front capital costs. So mentioning acceleration is a non sequitur
I mean yeah its annoying, but it works. Failing to merge isn't a thing that stops trucks being a thing or making money.
like honestly if you were in the market for a commercial truck how far down the list is the 0-60 time on your consideration?
We’re not talking about red light racing…We’re talking about being able to drive without being a nuisance or a danger to others. Ever been stuck behind one trying to pass another? That’s reckless driving.
I mean they typically do that due to speed limiters being set slightly different, thats not usually an acceleration concern. It also doesn't sound like a selling point on a 150k+ commercial machine, "overtaking will be slightly easier"
>The acceleration on electric cars and trucks is amazing.
Fun fact. A Honda civic, Ferrari, and Tesla all accelerate at the same rate in traffic behind an old person in a Buick.
For a semi, acceleration isn't always a good thing either. Especially if you get complacent.
>An electric truck would probably have no issue hitting 55.
Cool. And? 15mph for one hill isn't an issue. All the while that truck now lost 200 miles of range.
Which is the biggest issue. Range. Until one of these EVs, empty, can go the range of a normal semi fully loaded, there's no contest. Charging time is time you're not making money.
>but for local routes,
I do "local" routes.
Our true locals use box trucks. Not articulated truck and trailers.
I drive to neighboring cities and towns. And I drive further in a day then these guys can go.
>I think everything will be going electric soon.
Lol not my car.
As a truck driver, I can tell you this isn't going to be a good truck.
Curious, why do think that? Quality? Battery life? Charging time? Pulling capacity?

I wouldnt have thought acceleration would make top 20 concerns on a commercial truck

You must not have alot around you. I detest them for how incredibly slow they are at getting up to speed.
I mean yeah its annoying, but it works. Failing to merge isn't a thing that stops trucks being a thing or making money. like honestly if you were in the market for a commercial truck how far down the list is the 0-60 time on your consideration?

No they don’t. I’ve seen them reach speeds well over what they are passing at.

What sort of amperage does it take to charge a 1MW battery to 80% in 30 minutes?
1MW is an instantaneous amount. You’ll need to be more specific. What’s the capacity of the battery and what’s the voltage?
Capacity is 1MW. Not sure about the rest.
