Your car probably doesn't have these.... yet, hopefully many cars
will have them and the sooner the better. Perhaps the joint effort of Tesla and Toyota will lead the "charge" so to speak. If the prez really wants to help out... this would be a great place to start, help this venture go forward.

Toshiba’s Fast-Charging, Long Life Li-Ion Battery

5 April 2005

Toshiba has developed a new fast-charging lithium-ion battery with an extended lifecycle that has significant potential for application in hybrid and full-electric vehicles.

According to the company, the prototype of the battery can recharge 80% of its energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and will lose only 1% of its capacity after 1,000 cycles of discharging and recharging.

On those two criteria, the Toshiba battery meets the long-term specifications for advanced battery technology for vehicles set by the US Advanced Battery Consortium.

2. That is incredible! And meanwhile the gulf fills up with our primitive fuel.
The world seems to be going in two directions. Progressive, clean fuel, technology and.... backwards, superstitious, clinging to fossil fuels.

3. So you need a fork lift to plug it in?
"According to the company, the prototype of the battery can recharge 80% of its energy capacity in only one minute..."

Didn't anyone calculate the amperage required to recharge to 80% in one minute? This isn't going to work very well in a residential neighborhood.

5. In a residential neighborhood.... supercapacitors could be placed
in your garage... they could be charged at any rate... and they could dump charge as you like.

6. could these become the electric version of a "gas station"?
because until you can jump in your family's electric car and take the kids on vacation, these will be niche vehicles that won't replace internal combustion engines.


But, if you could stop somewhere and "refill" your battery it could replace a significant number of internal combustion engines.


Right now I am a "Compressed Air Vehicle" fan because you can refill the tank quickly and air compressors could replace gas pumps easily. This battery could easily turn me.

9. That is the idea but a network of stations offering the service needs to happen, whether regular gas
stations just install one(I believe they could with little effort if they don't already have the wiring) or it could be it's own business as well as other businesses offering it like shopping malls etc.

Without a network of stations, or some means to get that 80% charge, Electric vehicles would only be good for trips withing their charge range.

10. The massive amp flow would be very dangerous for consumer use.
Also ultra capacitors have this bad tendency to explode very violently when damaged.

Ultra high amperage and things that explode. Not stuff you want average absentminded consumer using.

11. Consumers use hairdryers in the bathroom everyday. They use
cell phones at the gas station... and they text while driving.

Safe, high-energy supercapacitors based on solvent-free ionic liquid electrolytes

Abstract
Safety is the main concern for energy storage-system application in hybrid-electrical vehicles (HEVs) and ionic liquids (ILs) of low vapor pressure and high thermal stability represent a strategy to meet this key requisite. The use of solvent-free ILs in supercapacitors enables the high cell voltages required for increasing supercapacitor energy up to the values for power-assist application in HEVs. In order to exploit the wide electrochemical stability window of ILs, tailored electrode materials and cell configurations have to be used. The performance of asymmetric double-layer carbon supercapacitors (AEDLCs) and carbon/poly(3-methylthiophene) hybrid supercapacitors operating with different pyrrolidinium-based ILs are reported and compared. This study demonstrates that a design-optimized AEDLC operating with safe, solvent-free IL electrolyte meets cycling stability and the energy and power requisites for power-assisted HEVs at the investigated temperatures.
Keywords: Ionic liquid; Double-layer supercapacitor; Hybrid supercapacitor; Activated carbon; Poly(3-methylthiophene); Power-assisted HEV

13. We are talking a whole MAGNITUDE higher amperage.
than a hair dryer. A cellphone is a very low amperage device.

12. Apparently you know very little about electricity and power.
We are talking about a very high level of power here. Nowhere in the links does it allude to the capacity of the battery, just to one cell. How many cells needed? Who knows, it does not say.

We need know 2 out of the 3 of the following: Power, current and voltage of the battery as a whole, not just one cell. The article supplies none of it.
Super capacitors have the same constants.

My expertise? I've taught electronics and have been an electrician. My boss for 24 years was a master electrician.
and on top of that, this subject (charge rates) has been discussed here on DU before and has been debunked.

While they may have a car battery that can be recharged to 80% of its capacity in 1 minute, the instantaneous power needed to do so for a battery large enough to power a car for 40 miles or more, would be huge, as in short circuit currents, till the charge built up enough for the voltage to rise and the current to drop.

Look up Ohm's Law.
