But there are issues with scheduling. When a truck has a delivery, that delivery has a schedule. You arrive by the time of your dock appointment or you lose it. I would expect battery swaps to be the same way. So an appointment is made in advance and what do we do to make sure we arrive in time for appointments? We arrive early. The whole point of the battery swap is to reduce wasted time charging. So how does it help to have to arrive 15 to 30 minutes early to make sure of meeting the appointment, vs. simply spending 45 minutes to charge? > > >>> > > >>> It's hard to imagine a battery swap for trucks that is so rapid that no appointment is needed.

As I've already shown, a single stop to charge can be concurrent with the mandatory rest period (in the US anyway, not sure what laws are like down under). Someone commented that in the EU there are more/longer rest stops required. So there is already time for charging and no need for swapping batteries. Charging can be accommodated at existing truck stops with the addition of the chargers. It won't require extra land or zoning issues. It's an easy adaptation and can even be blended with the parking spots every truck stop provides. I don't know how large the battery swap buildings would be, but there has to be space for the inventory as well as means to charge them. > > > So maybe someone should stop looking at the engineering minutia and > > explain the use case > > Maybe you should pull you head out of your arse and read *what has > > already been written* instead of writing reams more nonsense out of your > > own fetid imagination? > I'm having a conversation *here*.

What would be REALLY interesting is a Canonball coast-to-coast race with EVs. I wonder what the time would be? Remember, an ICE-powered car did it in 27 h 25 m in 2020.

You are an arrogant ass. There are no useful features available. You are the one who wants to discuss the web page. If you can't be bothered to explain it, I'm not going to jump through hoops to read the damn thing.

Nope, you are the only one who is in this conversation with me. You seem rather obsessed with it. It has nothing to do with anyone else.
> If you want respect, you need to show some respect first.
I literally have zero interest in your respect. Is that clear enough for you?

If you want to read and reply, fine. If you don't want to read and reply, that's fine too. But clearly, you can't not read what I write. You do seem to be rather in an odd state. You talk as if reading my posts hugely annoy you, yet you keep, not only reading, but replying. Yes, very odd.

You simply have no respect for my handicap which is very different from having no respect for me. You are clearly not the sort of person who I wish to converse with.

I don't see that at all. There are always people who get involved in bad ideas. Do you really not understand that??? If you don't understand that, you can't possibly judge useful projects from useless ones.

It may produce an ROI. That's not the question. Will it continue to produce an ROI and will it be an optimal ROI? I suppose if you have to have a solution today, then this might be useful. But I've already explained that this approach may not have legs and you may end up stuck with a lemon that has no support if the company goes under.

I haven't seen numbers, but I would be more interested in knowing if the ROI will continue after other solutions are available. Will this system remain competitive? I think the other systems will expand more quickly. Since Australia is a self contained, island country, it may turn out that this system becomes dominant there, while BEV trucks dominate in the rest of the world.

Not to say boor.
Ok, I am reflecting on what you say. I'm done with you. I've tried to participate in a reasonable conversation, but you insist on being highly insulting because of my handicap. You don't see it as important and that I should take the effort to read a web site intentionally made difficult to read, just so you can converse with me more easily. I think of your handicap the same way. Yours is a mental attitude, and that is often as incurable as any other disease. It's not like you have anything useful to say anyway. Your comments are basically, that this system is good and other systems are not as good. Brilliant! What insight!

With the basic chassis ($50,000?), $85,000 conversion, $120,000 batteries, it's a 1/4 million truck. Doesn't matter who owns it, customers are indirectly paying for it.

We used to deal with 5 to 6 mpg for big trucks. 30% of 37.8kWhr (1 gal) for moving is 9.37 miles for 12 kWhr or around 0.8 mile per kWhr.
BTW, Tesla Semi says less than 2kWhr/mile or more than 0.5mile per kWhr. https://www.tesla.com/semi

At the risk of asking a dumb question... how do they sync the speeds of the various motors? Does the vehicle have a single centralized servo controller, monitoring them all? In which case, one might ask what's the failure mode, if that controller goes on the fritz - -- Rich

Speed controllers do not need to be powerful. I don't see the need for a single central controller.

18 motors for an "18 wheeler" makes no sense at all. Look at the axle configuration for truck. It also makes no sense to try to add power to trailers where eight of the tires are.

Lithium batteries don't perform well in the cold, which trucks have to deal with. At -20 C the capacity is about 75%; at -40 C it is less than half. So those Tesla semis operating during the wintertime could see their range reduced to under 150/250 miles (depending upon the version). Of course, they could insulate the batteries and use a part of their energy to heat themselves (which would also reduce range).
