The formula doesn’t matter. There’s no way in he11 an electric tractor trailer will ever be able to do more than 500 miles on a charge. The Rivian EV pickup couldn’t even tow a 6000 pound trailer 80 miles. Loaded Tractor trailers weigh 60-120 thousand pounds. Add in 25-50k pounds in batteries and you’re hauling at < 50% of a diesel tractors capacity. Never, ever, ever going to be cost effective. Anyone who says otherwise is incompetent or lying.
The typical mas GVW for a semi is 40 tons. But what is the charge time for a battery pack big enough to power a 40 ton rig for 500 miles? At the maximum charge rate, I’m betting 12-24 hours.
A new Hummer EV claims 300 miles on a charge. Of course that is a best case scenario. The interesting part is the battery weighs 2900 lbs. That means that the battery weighs 1/3 the GWV. It weighs 9000 miles.
A Semi towing 50,000 would need over 17,000lbs of battery just to match the payload for 300 miles not 500 miles.
Anyone who says otherwise is incompetent or lying.
Anyone who says otherwise is incompetent AND lying. And sells cans of Unicorn meat.
Exactly the reason train traffic goes up with gas/diesel prices. Cheaper to ship via train.
The Gross Vehicle Weight rules in most states are 80,000 pounds.
The GVW of an empty truck and trailer is about 30,000 pounds.
That allows for 50,000 pounds of cargo for a diesel powered truck.
If a battery pack for a semi truck is 25,000 pounds, then the cargo is reduced to 25,000 pounds for an electric powered truck.
The economics are not looking good.
Add to that the weight for refrigerated trailers.
The whole goal of these EVs is to create a world where everyone and everything is located in smaller sections so we will all be confined to our “limited area.
