I am a actual truck driver. This is my take. The only semi that tesla is going to be able to convert over to electric is the ones like Pepsi Co or other trucks that go round trip less than 500 miles. Yes these trucks do exist I typically do less than 500 miles a day and come home and park it but than the facility would have to install charging systems. The math is kinda wrong assuming 7 cents per kwh to charge the semis it is more like 15. Not to mention typically most quick chargers on the road charge 50 cents per kwh so you are looking at 500 dollars to recharge the truck on the road which at that point it is best to buy diesel.
Final point is we are seeing data from the F150 lightening showing towing data of 1.4 miles per kwh pulling a 7000 lb trailer so I am honestly doubtful that a semi truck is going to pull a 46000 lb load 500 miles with a 1000 kwh battery pack and further how much does that battery pack weigh?
