Misleading title: this video has nothing to do with BMS

from 1:10 onwards they're pointing the camera straight at the BMS screen!

There are cells that charge in minutes. Hook up A123 li-ion batteries to a high current powers supply and they will be 80% full in less than 5 mins.

The limit with charging a large EV pack is the power supply current. A 415v 3 phase 100 amp supply could charge a 25 kWh pack to 80% in approx 15 mins... but the limit is the power supply not the battery.

Is there any battery pack that can really charge in minutes or is it just vaporware?

To be honest Tesla Motors aren't even a car manufacturer, they have the same business model as a fabless chip company.

A short list of the majors now investing $100s of Millions in full scale EV production reads like a who's who of the auto industry. Mitsubishi, Nissan, Toyota, Subaru, GM, Mercedes, BMW, Audi, VW with battery suppliers like Panasonic, NEC, LG, Sanyo, Continental.. many of the same consumer electronics companies that flooded the world with plasma TVs... EVs will happen.. SOON.

The Tesla is mostly carbon fibre also.

Guess they will be selling to rockstars, rappers, and pro athletes. I know that one reason for the high price tag is the extenstive use of carbon fiber.  I just read Gizmag's article, "The affordable, 100mpg, carbon-composite passenger car". It says mass production of Britain's Axon cf auto panels will be cheaper than metal. Exciting times!

On my motorcycle I stop every 150 miles for gas. Give me an affordable electric car, or motorcycle, with a 100 mile range and I'll be happy... especially if a charge only takes a few minutes! With mass production of these new nano batteries on the horizon, maybe Tesla's next vehicle will benefit from the new improved batteries?

[tsport100]

PS, one simple explaination is that the Tesla costs about 40% of the 'expected' price of the Ligtning. That's really an insane price point for a first car from a manufacturer with Zero track record.

[tsport100]

IMHO I think it's because the Tesla has an oversized battery pack to placate buyers with 'range anxiety'. This means they must buy mass produced Li-ion cells at the lowest possible price.

The Tesla has a 50kw/hr pack that contains 7000 cells and costs $30,000 compared to the Volt which will carry a 16kw/hr pack.

Nano tech batteries still carry a premium but when GM and others start mass production of these cars in 2010 prices of Nano batteries will surely drop as supply increases.
