Read on @CNBC why Tesla is poised to make "range anxiety" a thing of the past. Phil LeBeau's Behind The Wheel - CNBC

After visiting Tesla headquarters and meeting with the management there, J.P. Morgan is telling clients it can see Tesla developing a 400 mile range powertrain in the next 3-4 years.

J.P. Morgan’s Patel believes, “Tesla’s battery pack costs would probably fall prospectively about 25 percent in each of the next five years [i.e., to around $225/kWh in five years from today].” Patel adds the drop in costs could happen even sooner.

“We suspect this timeframe may even prove conservative, as we have recently sensed that Tesla has already identified many of the technical changes that it plans to make to its current generation battery technology (i.e., that to be used in the S) to be able to create a 400-mile range capable vehicle.”

interesting!

replace the current battery pack for the roadster with 2300mAh cells with 4000mA cells. the battery pack may have 30kg more weight but 80% more range, even with the 3400mA it can be done.

What type of battery technology could make this possible within 3-4 years? None the less it is an interesting article.

I'm sensing an extended range Roadster battery in my future.

of what i understand, panasonic comes with a better batterycells this summer 4kv in stead of 3.4kv

The "25% in each of the next 5 years" puzzles me since Elon has said in various interviews something like 8% gradual improvement per year.

They may be exaggerating, but if we suppose that what Tesla said re: them being able to make a pack bigger than 300 right now as truth, then it's possible they're already able to do 380 or even 400 right now, but a gradual reduction in price (and more efficient packaging) over the next couple of years could make it palatable from a financial perspective.

The cells in the roadster current pack weight 300kg only plus 150kg for the pack, including the steel shell for each cell. if the new nickel based panasonic cells are more safe, than weight can be reduced or to add more cells without sacrificing safety.
400miles can be done for the roadster with the current panasonic cells right now.

That line was a bit confusing. I think they meant that prices would reduce by 25% every 5 years. So 25% by 2017 and 43.75% by 2022. So not each year of the next 5 years, but each group of 5 years.
