If you want to make an electric truck work, you can work around the limitations
Very few of us can drive for 1,500 miles at speed limit without a bio break. In fact, regulations in Canada state one must take a 30 minute break every 8 hours. So, you are looking at ~500 miles + appropriate reserves before you need an energy restoration.
A class 8 truck requires just over 200hp to travel 110 km/h. Which is why the 280 hp N855 I historically drove could tool along at speed limit. Power breaks down as follows:
53% Aerodynamic resistance
32% Rolling Resistance
9% Auxiliaries
6% Drivetrain.
Tesla with their class 8 truck reduces aerodynamic resistance by 40% through moving driver to cab center and designing an aerodynamic cab, closing the gap to the trailer, improving airflow under trailer and controlling airflow behind trailer. They do the same thing with their cars – they are much more Taurus jelly beans, than rugged Wranglers.
Back in ‘80s, Audi demonstrated with their Quattro AWD system, that a driven tire has slightly less resistance than an undriven one. So, Tesla tractors will have all wheel drive. In fact, they would like to power the trailer if possible. Hybrid powered trailers work behind ICE tractors too, but adding motors to trailer makes them expensive so not a commodity item – you don’t just drop yours and hook up to next one.
Electrically driven auxiliaries shave a couple percent as per Ranger discussions re: electric cooling fans/power steering/brake booster/etc.
And electric drivetrain has about half the losses – no transmission, no differential.
The result is the Telsa truck needs about 70% of the power of the classic Kenworth W990 to pull the load. Of course, all the above can be applied to an ICE tractor – you just have to convince truckers that a tractor that looks like the nose of the Bullet train is the future.
NRC studies show 60% of trailers are cubed out before they weight out – unfortunately, I can’t find numbers on what the average load is.
On other hand, I supremely doubt California’s electrical grid can sustain a significant increase in load - Last time I checked, they had issues meeting current load.
Personally, I think hybrid is the solution; but that is worst of both worlds in the both the ICE and Green camps.
And my favourite Looney Toons character is Jessica Rabbit – she’s not bad, she’s just drawn that way.
