Tesla batteries are surprising heavy, especially when compared with batteries found in ICE cars.
The Tesla Model S comes with various battery sizes, like 60, 70, 75, 80, 90kWh, etc.
An EV with a larger (like a 90kWh) battery would be heavier to handle, compared with an ICE vehicle.
Since we already know the weights of the batteries in different models,
calculating the weights of all of those models is easier when we subtract each Teslas battery weight from its curb weight.
Having structural batteries means Tesla will be able to keep weight at the level of the cars structure, making energy density at the car level significantly higher.
While Lithium-ion batteries generally have about 17 pounds of Li for every kWh, a battery pack for Teslas 70kWh vehicle could have as much as 138 pounds of Li.
While it is not clear what a Teslas first electric semi truck would weigh without its trailer,
a trucks battery pack alone may weigh up to 11,000 pounds--a number
that would rapidly devour the max gross weight for an 8-wheel-drive class-A truck, which is 80,000 pounds.
