Fugly little thing.
So, who wants to be spam in a can ?
Makes a Yugo look like a Buick Roadmaster.
Yes, fine; when you’ve got your elecric car technology all squared away - say, fifty years from now - give me a call.
Well, at least it makes the Leaf look good.
Gee, only $21.6K (after the tax rebate). You want fast charge? Add another $2.8K.
62 miles range, 0-60 in 15 seconds.
Still a way to go in development. Even a 5% loss in a hundred cycles is not insignificant for a device like a car.
Who cares? Give it up.
Check the battery.
Why don’t you check the keywords? My interest is in the battery. Chemistry was my undergraduate major.
EXCEPT that the batteries have ten times the energy storage of existing technology according to the article.
SO if current battery technology has a 60-mile-range - a 10X improvement implies about a 600 mile range. AND 100 cycles then would cover 60,000 miles. Well, that is not too shabby.
SO if the car when new has a 600-mile range, and after 100 cycles (lets say 50,000 miles) has a 540-mile range (10% less), that still works. Just fine, in fact.
The other main issue is how long to recharge. For a daily driver in town obviously this isn't an issue as you can recharge overnight, and this sort of range is plenty for several days driving.
OTOH, on a long road trip I rarely choose to or WANT to drive more than 4-5 hours at a stretch, and thus 300-350 miles between stops, even if the car is still more than 3/8's full. If I can recharge in 30 minutes or so, then road trips are still OK. MAYBE I might go an hour and accept the penalty, and have lunch or whatever while waiting. But longer than that and I am not sure it works cross-country.
BUT for example - to drive to my father's place in the next state over is 255 miles and 4 hrs. If an electric car has that sort of range, let alone 600 miles or so - this is a big big deal.
Make the electricity with natural-gas fueled generating plants, and things are a LOT different in a good way on lots of levels.
Lets say just around the house driving one fills up once a week that's a 2 year life for the E car. Their are lots of gas cars will over 10 years old.
Give me a E car that gets 400 miles per charge 10 min recharge and thousands of them.
Then one might considered one
So... what are you saying, exactly?
Because your interest is in the battery, no one is allowed to comment on anything else???
Did they say how much it was to replace the battery? For a regular commute that is almost a 15% degradation for a year. And that is assuming the commute is less than 30 miles each way.
Go back to the drawing board kiddies.
Where do you plug in when you are in need of a charge? Does it come with a long cord that will discretely hang from the second floor window of the Holiday Inn?
Why not just have natural gas cars instead of burning the natural gas (or coal etc) to make the electricity to charge the car?
Tesla claims a range of up to 300 miles on their new Model S. It looks like a normal car, at least.

100 charges and discharges? Ok......so there’s the first three months of use. How about the next five years?
