Don't worry, it just needs to use 5 supercharger slots to charge up. Not going to be a problem https://electrek.co/2018/12/13/tesla-semi-black-prototype-supercharger/

I dunno about the States but in most Eurotrucks cruise at ~100km/h (60mph) so your relative aerodrag will be lower and also the efficiency of scale will be generally in your favour. Still a fuckton of batteries and garbage range compared to any other truck.

there's a reason they don't and it's because it's a terrible idea for most of the things you use a semi for, with the exception of yard vehicles, and lo, they do already make electric versions of those

conceptually, it's very stupid (like most of musk's brilliant ideas), because the energy density of lithium batteries is so much lower than that of diesel, you need shitloads more weight to even approach the range and capacity of a regular semi. at which point you're starting to hit the weight limits of the vehicle, and you have to start reducing cargo capacity. and no matter what kind of charging infrastructure you have, waiting 8+ hours to charge your vehicle is a nonstarter.

Still a fuckton of batteries and garbage range compared to any other truck. This semi is not (or should not be) for long-haul transcontinental trucking. Its for short haul or drayage use, where there’s a lot of stop-start and not cruising at high speed. Also, in Europe trucks are actually speed-limited. Here in the US interstate trucks will routinely drive at 70-80mph, not 90km/h.

The amount of extra fuel you need to propel an aerodynamic brick wall (truck) at those speeds is rediculous and the time difference is marginal.

Some trucks in the US are governed to 60mph. hell, my brother is a trucker and his truck is governed. it depends on the company though, not any government regulation.

I drove an electric Freightliner Cascadia two weeks ago. Lots of companies are building electric heavy duty vehicles, but no one is targeting long-haul (and none of the companies that have given ‘ol Musky money for his semi are planning on using them for long-haul (unless they are very stupid).

It’s almost as stupid as thinking it’s a good idea to make electric cars drive through a tunnel at 155mph instead of 55mph. Big trucks here don’t even have anti-submarining protection under their trailers like they do in Europe.

US trucks are supposed to have trailer underride guards, just.. lots of them don't and they're only on the rear and they kinda suck.
