The same goes for lithium batteries. There is no way a mass-produced OEM system with roughly 10 kWh of capacity should end up priced at $30k (retail). Not when we consider they eliminate the cost of the Onan.
The Tesla 85 KWHr battery has 7104 18650 size cells that have around 12 WHr each.
Panasonic 18650 cells are $4 apiece and they each have 10WHr. 10KW/10 x $4= $4,000. Tesla uses around 7,000 18650 cells and the cost at $4/cell amounts to $28,000 which sounds about right. A 10 KWh should cost around $4,000-$5000. I would hope that the retail cost should be less than $8,000. It's just my guess based on very little known data.
The Chevy Volt battery uses it's own structure including coolant channels to cool or warm the battery, adding to it's cost. I think it is a 14 KWhr battery.
