So EV trucks are fine for driving around town, but if you're leaving town you better plan your trip around recharge stations. If you're towing or hauling anything, double the time you planned the trip to take, make a stop at every recharge station you see, and plan to sit waiting for a recharge station because "no trailers allowed".
no thank you

Ok im not a electrical engineer and dont claim to be and never stayed at one of the Holiday( whatever it is called where you stay and get a supposely brain transplant to make you smarter). But can someone explain to me in layman english why they dont install a alternator/generator on these EV's to recharge the batteries, to me looks like a simple pulley and belt on the drive shaft or electric motor would work to recharge the batteries while driving.

The closest you will get is with regenerative braking. Having the motor trying to overcome the drag of an alternator/generator would consume more energy than it would produce. The plus side to regenerative braking is the drag to generate electricity also helps slow down the vehicle.

EVs don't have engines, so an alternator would be lacking its power source. It would be possible to use an electric car's rechargeable battery to spin the alternator, but this would be self-defeating, using up more electricity than it generates.

That's just the first thing I found.

By saying the "...the electric truck had the energy cost advantage." doesn't take into account the cost of your time and energy wasted planning and wishing you make it to a charging station and then waiting "15 to 45 minutes for an 80%" charge.

Why not just use an efficient gas engine at that point?
