Ivan: You're right. The costs will undoubtedly decline as production volume rises, and that will certainly boost sales. Most analysts say, however, that the costs won't drop below $400/kWh, and may remain as high as $650/kWh, even as economies of scale kick in. (With the exception of Tesla, which employs 18650 batteries, today's costs are approximately $800-$1,000/kWh.) Assuming an optimistic cost of $400/kWh, a 40-kWh battery will still cost $16,000.
What about the costs of producing the batteries? One way to increase demand is to drive down teh costs. I am not sure what the cost breakout is but R&D must be significant. I would also expect eh electronics to manage the battery charging and discharging to be significant as well but probably very sensitive to demand. after all once the basic controls are designed and implemented with approppriate processors they are readily amenable to cost reductions liek the rest of the digital cotnrol systems have been. The matieral cost, Lithium and some alloys I am told are not so expensive either.
As we mentioned before increasing the demand by other than EV uses might also be possible. I can see homeowners adding batteries when they can store lower cost energy for use during higher cost times that depend on their local utility cycles.
Coupling batteries with wind and solar systems would also increase demand but drives the costs of the systems up significantly.
An industry shakeout is coming for sure regardless.
You're right, Rob. High expectations play a big role in this. But the analysts we talked to allowed for a wide range of possible scenarios -- a demand of 2 GWh on the low end and 20 GWh on the high end. Even at 20 GWh, however, the demand is still about 10 GWh short of the supply. As a result, companies will still be winnowed out, even under those relatively good conditions.
In reading between the lines, Chuck, it sounds like there were high expectations for the EV market that didn't come to realization. Otherwise, why would the market pump up to the point that a shakeout is coming? Have EVs been less popular than expected? If so, why? Is it the costs? Performance issues?
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
