I thought I might post this since it is our future in cars and Aaron likes cars.
Electric car recharges in 10 minutes

I saw this about a week ago on The Register. The thing is, the article claims things that are impossible. This article leaves out one small fact: the original article claimed a 10 minute recharge from a standard 120V outlet. Obviously, that outlet cannot supply enough power to charge a battery pack capable of 200 miles in 10 minutes.
A 10 minute charge itself isn't really that special, to be honest. EV racers have long been charging packs using "dump charging" in the pits. Li-Ion will handle fast charges up to about 80% of capacity as long as heat is kept in check. The real issue is that this requires a huge amount of input power, and most homeowners don't have 480V service.  |

Yeah, there's the catch. My dad made me aware of this car and now I'll have to explain to him that the claim isn't so great after all. But still, if it is true that a battery pack with that much capacity can be charged in 10 minutes, then I consider that amazing since battery technology is the primary thing holding electric cars back. Once the battery tech is better, we will all have an electric car. We cannot afford to fund terrorism anymore with our gas guzzlers. |

It's interesting that it's not really battery technology holding EVs back, but the auto makers unwillingness to license existing technologies. There are plenty of good battery chemistries out there yet few are being used by manufacturers. They insist on developing "in house" and thus, begin from scratch. I don't know why. Perhaps to avoid paying licensing fees? Battery tech is quite impressive these days. I just bought a new Blackberry and it's Li-Ion battery is 3.8V and 1400 MAH yet is perhaps 1.5 inches square. That's extraordinary.
The Shelby article also mentions their car is 1,000 HP. I find that a bit suspicious. 745,000W....really?
Funny thing is that Daily Planet on Discovery did a short segment on this car. Their stock footage showed a twin turbo V12 while they were talking about the electric motor.  |
