Does Tesla Semi Break the Laws of Physics?

Does Tesla Semi Break the Laws of Physics?

The cabinet and cooling are not optimized for lowest weight. In the truck, the cooling systems would not be duplicated and would be more efficient due to moving air under operation. The physical cabinet would be built into the chassis, thus saving weight as well. We can estimate the battery weight per 210 kWh at about 3,300 lbs. 500 kWh would require about 2.4 times the weight of one Powerpack, or about 7,900 lbs, a penalty of only about 900 lbs for the 300 mile range vehicle. For the 800 kWh pack, the weight would be about 3.8 x 3,300, or about 12,500 lbs, but a long-range diesel sleeper cab should be compared and that is an extra 4,000 lbs, or a total drivetrain weight of 11,000 lbs, so the Tesla Semi comes out to about 1,000 lbs more for the 300 mile range Semi (~19,000 lbs), or 1,500 lbs more than a sleeper (at ~23,000 lbs). Those weights are competitive with existing ...
