They can very happily provide steady flow if only they have enough of charge - big enough capacitance.
The current state is that, they are about an order of magnitude behind chemical batteries. This might sound bad, but they have made some giant leaps in last few years. They advanced for quite a few orders of magnitude already - from miliFarads to kiloFarads.

But nanotechnology promises impovements in both fields. We'll see.

Has anyone heard about the new Subaru R1e?? Its supposed to charge 90% in 5 minutes!!!!! and a range of 120km to be extended to 200km by production in 2009.* Who says no car company is interested in battery technology, Subaru is teamed up with Tokyo Electric to delvelope an all electric car battery.* Mitsubishi is doing this as well.* Seems like US and Europe auto companies arent thinking about the possible future.

Heres a link to the Subaru R1e

Hopefully Tesla doesnt make the same mistake with the batteries and hopefully they have better customer service as well because thats another reason why Dell sucks.

i don't have one of the recalled batteries but dell still sucks alot. at least you get a new battery

I think it's safe to assume quick 5 minute charging stations will start to pop up right next to gas stations pretty quickly here. 3.5 hour charge time is fine for when you're at home. 5 min for when you're on the road. Sounds simple. Plus it's not like gas stations aren't aware their days are numbered. This is a easy add on for them. Like a gas truck, these stations will have massive electric connection "bandwidth" if you will.

I completely agree.

Seems to me that if Tesla was able to utilize a battery technology that had minimal, if any, loss of recharge capability; e.g., ultracaps; then we could reduce the average cost per mile of operation to only the cost of the electricity instead of having to include the cost of replacement batteries. Wouldn't this drop the average mileage cost from 20 some cents per mile to around a penny?

A123Systems Unveils Lithium-Ion Battery Technology that Delivers Unprecedented Levels of Power, Safety and Life

Nanotech-Enabled Batteries Deliver up to 10X Longer Cycle Life, 5X Power Gains and 5-Minute Charge Time; Company Discloses Multi-Year Deal with Black & Decker to provide battery for its DEWALT brand of Power Tools

RC enthusiasts over at http://www.rcgroups.com/forums/forumdisplay.php?f=129 are confirming everywhere that these batteries are capable of being recharged in 15 minutes, with little observed loss in capacity.
If you wanna test it firsthand, get a RC model and battery/charger from http://www.a123racing.com/html/soniccharge.html

Only problem, putting together a 30kWh pack of these will easily bring you to brink of bankrupt ...

It does seem that many of our current gasoline stations will end up being high amp "quick charge" stations that will "fill" our future wave of electric cars (with whatever type of battery cars they may have) and/or they will become "Battery depots" where battery (or partial battery) hot swaps happen.

I just want to put it out there that the Tesla's on board navigation system should have all of the staions programmed into them AND be updateable via a tranmitted siganal or mailed chip or disc update.

cheers,

eric

Perhaps electric cars could help companies like mitsubishi that are struggling right now get back up.

I'm not sure if the gas station as we now know it has much future.* If the great majority of charging is done at people's homes, in their garages and carports, that doesn't leave a whole lot of business on the road.* Tesla Motors said their long-term goal is a car with 500 miles driving range, which is about all most people want to go in one day's time.* Following that scenario, there could be charging stations in homes and at hotels, motels and campgrounds, and that would just about cover everything.

I'm particularly skeptical about any battery-swapping schemes.* It sounds like a neat idea at first, but the problems associated with bad batteries, worn-out batteries, or just plain fraud would be hard to overcome.* It wouldn't inspire confidence for most people, and confidence will be a big part of getting electric cars accepted.* Also it has been pointed out that making Li-ion batteries hot-swappable isn't quite so easy, since they have liquid cooling systems running through them.

Yet another punishment car.
