Because structure makes up a small percent of an electric car mass and batteries make up a big percent of electric car mass.
Let's say that it's 10% for structure and 30% for batteries.
If you decrease energy density of batteries several times now they take up let's say 90% of the car mass and the only thing you saved was 10% :)
- framecowbird 6y ago10% for structure might be an underestimate. I did a Google and it suggested 25% for suspension and chassis and another 25% for body. Obviously that includes more than what you could make a battery, but I reckon it’s more than 10%. Also, even if it’s only 10% weight you are saving, that sounds pretty good to me!
