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. |
Tesla is getting close to the magical $100/kWh price point--I know at this point they are below $200 now.
The latest incarnation of the Volt has an 18.4 kWh battery and the Bolt has a 57kWh battery (even though Chevy has it spec'd for 60kWh).
Both the Volt and Bolt use prismatic cells which are larger than the small cells Tesla uses (and thus they have fewer of them).
The Bolt has a cooling plate that the batteries are mounted to--a much easier manufacturing method than Tesla's snaking the coolant tubes around the batteries.

Given time auto manufacturers will take a ton of cost out of batteries...
