MIT Kids Make Battery Powered Car - Charges in 10 Minutes (gas2.org)

Charges in 10 minutes....IF... You have something that can give it 350kW.

I don't know enough about battery tech to know if there's anything special about super quick re-charges - but it's a long long way away from being a practical home solution - and I'm not seeing it doing all that much above something like the tesla.


I think the idea of charging in 10 minutes is that it brings it into the realm of service stations and out of the charge at home model where it takes all night. (However a good slow charger would still be an option.)

Traditional electric cars charge at home or at work because they could only accept a charge at a fast enough rate to fully charge over hours. Household 220 was up to this task but was not the limiting factor.

It takes me 3 to 7 minutes to gas up now. If it only took 10 minutes, an electric service station would be feasible. It wouldn't be that difficult to build a station that could supply a dozen multi-hundred kw charging stations. The stations would probably love it because, unlike gas, you wouldn't have to stand there and watch it for spills and 10 minutes is just enough time to run in and pick up a latte.


Have you seen what Better Place http://en.wikipedia.org/wiki/Better_Place and http://www.ted.com/talks/shai_agassi_on_electric_cars.html -- who are trying to roll out a battery replacement scheme - "gas" station fill ups in <5 minutes.


I get the benefits and the importance in the long run of the accomplishments made by this research team. Nonetheless, that doesn't take away the sensationalistic tone of the article.


I'm wondering if the Tesla could be charged in 10 minutes with a 350kW power source/station.

Also: Another hitch is the cost of the battery array. It runs about $80,000

Cheers to the MIT students for their great work, but it doesn't seem like they'll be "easily competing with petro-based vehicles" so soon.
