20 KW.hrs in 5 minutes is a lot of juice! That would be what, 18 households worth of power? I hope you'll be able to start the charger from a safe distance away, behind a concrete wall!

I for one would like a single charger for all electric cars, otherwise its gonna be mobile phone chargers.

You'd need a 240/250KVA connection to charge that fast.
A connection like that is capable of powering a medium sized supermarket!

What part scares you so much?

The technology exists already

http://articles.nydailynews.com/2011-10-10/news/30284522_1_charge-electric-vehicles-nissan-leaf-electric-car

Nissan, in conjunction with Japan's Kansai Nniversity, says it has created the necessary technology to charge the batteries needed by vehicles such as the Nissan Leaf and Mitsubishi iMiEV in a record time of ten minutes.

However even Nissan say the technology is still about 10 years away from commercialisation. As we invest in a smarter grid, it could be possible that these chargers could respond to the load on the grid i.e. increase or decrease charging rates as the local grid allows for.

I thought this was a thread about the New Tesla Model S?

I must have missed the Leaf portion of the title.

"250 KVA capacitor" makes me think "explosion", and pumping that much power into a battery makes me think "electrical fire". That's the kind of equipment normally surrounded by a high fence with High Voltage - Risk of Electrocution signs.

I certainly would advise against sitting in a car hooked up to a 250 KVA supply.

That still doesn't really explain why. I think of different things when you mention those keywords, what makes you think those outcomes are likely? Electricity is a technology we've had for quite a long time. It's not like we are lacking experience or knowledge in this area, or do you disagree?

It looks beautiful and I like performance figures. I'd throw my Leaf off a cliff if it meant I could have a top spec Tesla Model S

When was the last time you, personally, touched a piece of electrical hardware rated at 250 KVA?

Seriously, this is the sort of technology we have kept the public far away from with high fences and brightly coloured warning signs showing stick-men getting electrocuted for quite a long time.

And what exactly is your point ? electricity "can be dangerous ?" sure it can so can your car catch fire filling it up with petrol.

The chargers will be well capable of supplying the power and will fully comply to every safety regulation, so I wouldn't be worried.

How anyone could compare a charger to a sub station is beyond me!

Your battery will also have safety regulations to ensure you are not cooked.
