One word: Batteries
This battery will give you an idea of how much it will cost.
It’s a rechargeable lithium ion cell…and quite larger than an AA.
It will cost $12 to buy 8 AA rechargeable lithium-ion batteries from Walmart.
So – $1.50 per AA cell.
It is easy to see that the Tesla cell, which is much bigger, costs $2.50…right?
A Tesla Model 3 battery pack has 4,000 of these cells.
….$10,000 should not be a surprise.
Each cell must then be monitored and heated or cooled according to the need. Finally, it is packed in fire retardant foam.
