That is, the possible cost is around $400,000 for the battery pack alone.

Meantime, the article cites an estimate for a 600 mile range. Is this a typo, or trying to "enhance" the bear case? Given how "accurate" both the bulls and the bears tend to be when hyping or damning Tesla -- this is why I say we need to wait for the price.
I have no doubt it will be higher, perhaps significantly higher than a regular semi. But if it's cheaper to run and will last far longer, it may be well worth the price. Then, as battery prices come down, it's all advantage Tesla.
This, of course, only works if they survive to 2020 and beyond which, IMO, is far from certain the way they bleed cash and demand lots of additional capital raises.

Last night my Powerwall went off-line twice for 30 mins each time. It fails over to the grid so I didn't notice. I saw it this morning and wondered, I figured they downloaded and installed an update...
Today I get home and look and the charge curve has changed dramatically. It is now charging at a constant 5 kW rate again. This has happened twice since I've had it. The charge curve has changed on it's own.
We talk about battery swaps and professionals who are responsible for maintaining an EV battery...My battery is being maintained over the Internet by professionals without me even knowing.
If it wasn't for my level of data analysis I would never have known. The battery is now charging much faster than before.
EV Range Set To Triple With New Lithium Battery BreakthroughThe University of Waterloo researchers breakthrough involves the use of negative electrodes (the anode) made of lithium metal, a material with the potential to dramatically increase battery storage capacity. The increased storage capacity, or energy density, could boost the distance electric vehicles are able to travel on a single charge, from about 200 kilometers to 600 kilometers (360 miles). The team’s research paper has been published in the journal Joule.
In creating the technology, Pang and fellow researchers, including supervisor Linda Nazar, a professor of chemistry and chemical engineering at Waterloo, had to overcome two challenges. The first challenge involved the well-known risk of fires and explosions caused by microscopic structural changes to the lithium metal during repeated charge-discharge cycles. The second involved a reaction that creates corrosion and limits both how well the electrodes work and how long they last.
Researchers solved both problems by adding a chemical compound made of phosphorus and sulfur elements to the electrolyte liquid that carries electrical charge within batteries. The compound reacts with the lithium metal electrode in an already assembled battery to spontaneously coat it with an extremely thin protective layer. We wanted a simple, scalable way to protect the lithium metal. With this solution, we just add the compound and it works by itself.”
The team’s work is truly a counter intuitive success. Its seems after a review of the paper that the technology may be incorporated into battery manufacturing without a complete retooling and massive investment. This may be the breakthrough that more intense use of battery power needs to expand the market for devices.
I saw your name on this thread and didn't even have to read your response. I knew exactly what you would say. Some variant of:pstarr wrote:Your understanding of applied science pales before your ignorance of theoretical science lol
Read your blurb, and then promise me this blindingly exciting tech will be ready before the seas rise and hell freezes over.

while we're discussing the cost of electric batteries for trucks, has anyone seen Real Engineering crack the numbers? He makes an interesting case. It won't be the same as existing trucking business & shift models, but there does seem to be an economic case.

eclipse wrote:Probably all true, and as a New Urbanist I don't really like cars that much anyway. But can you imagine how fast the shift to electric trucking could be (even with current limitations) if oil prices start to rise, permanently? Even if there was a half hour fast-charge every 500 miles. Even if there's a third reduction in freight capacity. This is national infrastructure - even national security! Who knows? Maybe some company would smash together a hydrogen burning truck and manufacture hydrogen at their warehouses, after all all you need is electricity and water.
I guess the main point I'm making is that it's almost viable today, and the technical reality is not anything like this strange gal's vibe.
