Which is double the size of the other trucks to which it was compared to in the article. So either they're making a massive tradeoff or have managed a physics breakthrough (battery weight or density).

- Animats 4y agoThat's about 15,000 pounds of battery, correct?
- vardump 4y agoNo one knows exactly, but I'd guess closer to about 10000 pounds. Semi's battery is not going to need as much armor.
- Animats 4y agoTesla Model Y battery: 81 KWh, 1,700 lbs => 21 lb/KWh. (Lithium-iron phosphate) Tesla Model 3 battery: 82 KWh, 1,060 lbs => 13 lb/KWh. (Lithium-ion) 1000KWh in lithium-ion: 13,000 lbs. Teslarati guesses around 15,000 lbs.[1] A typical semi-truck without trailer weighs 15,000-25,000 pounds. So 15,000 pounds of battery is not hopeless. The Hummer EV weighs 9,000 pounds, after all. Tesla can, and probably will, sell the "extended range" version for a premium price. There are many semi-trucks that never take long trips. This is mostly a battery cost problem.
