ElectrIQ Power 10Kwh: $1300/kwh
GBS 48V 100Ah Li-Ion Battery Pack: $670/kwh
Yes, ... and no.
Battery production costs will soon be about 112$ / or so, so 10 kWH ==
1100 $. At 26 kg mass, more or less.
Retail costs, typically, from major ( chinese / import) manufacturers
are == 20-40% plus manufacturing costs.
Straubel of tesla said it well, few months ago.
ANYTHING made in scale approaches materials costs (with some delta for
margin).
This applies today to tanks, trains, cars, aeroplane parts, etc.
Today, I could make or have made, anything, for 6-8€/kg.
The cost of mass-producted good in metals is 6-8 €/kg in qty (anything
non-nuclear with major worth).
The exact same things has happened to auto parts like transmissions.
A modern auto has 3 expensive parts.
Engine. 3000 $.
Transmission. 3000 $.
Everything else. 3000 $.
All cost about 3000$ at basic models, and scale up from there.
Yes, they all have approx. equivalent costs, and a total basic sedan ==
9000$ from suppliers.
I used to sell CNC machines to the people making the parts, all data is
correct with caveats.
For example, solar cells costs dropped 200 times, or 99.5%, in 16 years.
Today, they cost 0.39 - 0.40$/W to make, retail for == 0.50$/W.
All data available on the stock exchanges and 10Qs from listed companies.
The exact same thing happened to servo drives (electronics), RAM, HDD,
PCs, motherboards for PCs all electronics.
A new (basic) PC MB today can be had for 10$, retail.
Unless You use unicorn-horns etc. to make something, anything can be
made very profitably for 4-8x materials costs, if the PO is big enough
to cover the machinery.
And the QTY is quite small, in truth.
Steel/CI == 1-3€/kg, alu 3-6/kg.
A battery pack / tesla car or similar, for example, without cells, is
about 3-500$ in qty 50k.
Including conduits, pumps, everything.
Its is less than 100 kg of very basic mechanical manufacturing.
A caterpillar dozer, china, is about 6-8€/kg.
A servo drive, ac brushless, as good as a japanese fanuc, is ==150$.
The japanese one is 2500$.
I have used these for years.
