The reporting seems to be that the Tesla Semi truck has just done what near all said couldn’t be. Carrying a full load for 500 miles without recharging.
Not wholly, entirely, convinced myself. Now, I don’t know ’bout US rules but here in the UK it’s the total, laden, weight of the truck that is allowed onto the roads. If the batteries weigh several tonnes more than a truck with an ICE and a diesel tank then that simply must mean a reduction in carrying load – beause trucks do tend to bump up against that allowable upper limit of total weight allowed on the roads.
So, I’d guess – guess – that the total allowable carrying weight of that Tesla Semi is lower than of a diesel truck. Meaning that it’s not the price of the truck plus fuel, it’s the price of more than one truck (say, 1.2 trucks, just to have a number) against one truck.
However, it’s also possible to think back the other way. Actual truck loading is a weight/volume problem. Carrying a truck of potato chips isn’t 40 tonnes. Carrying a truck of Pepsi cans is – we might well not fill all the volume before hitting that weight limit.
So, say that the Semi can only carry – because battery weight and total loaded weight limit – 80% of the normal maximum weight load. That’s only a problem for things which do hit, on that weight/volume basis, the weight limit of the load, isn’t it? And how much of road freight does that?
I’ve no idea what the answers are here. I think I’d get close to insisting that given battery weights then total possible carrying weight is lower. But how important that is I don’t know – because how many truck loads are weight, instead of volume, limited?
We got any experts around here?
