Company Builds Fast Charging Station For Electric Cars
thecarchik writes "Japanese based JFE Engineering has released its ultra-fast charge station. Designed to comply with the CHAdeMo standard developed by Tokyo Electric Power Company, Nissan, Mitsubishi, Subaru and Toyota, the system is capable of charging a 2011 Mitsubishi i-Miev from empty to 50% full in just three minutes. Even just three minutes plugged into the fast-charge station was enough to enable a standard 2011 Mitsubishi i-Miev to travel a further 50 miles before further charging was required."
This thing is putting nearly a quarter megawatt (240kw) drain on the power grid during use.
I wonder if it has some sort of means of load smoothing and a limited duty cycle, or if it's going to need its own substation.

I have never owned or even driven one save for a golf cart. My experience with the golf cart leaves me doubt as to whether an electric car can deliver enough torque to climb steep inclines.
Have you tried a Tesla? I hear they are fast.
Heck, what happens when you are stuck in snow all the while, the spinning of wheels eating away at your juice? Scary, isn't it?

they lack the range to be useful outside of a commuter scenario
And that scenario only makes up, what, about 80% of the passenger car miles driven in North America?
If libertarians are so opposed to effective government, why don't they all move to Somalia?
And regarding the snow? Yea, electric cars do just fine there:

Er, what? When dealing with electric motors, you have much more torque than a comparable gas motor.
That is when you go to the grocery store, buy all their AA batteries, wire them in parallel and hope it is enough to get you to the next volt station.
I think that, on some level, owning a car actually represents a certain measure of personal freedom to many individuals in our society: specifically, the freedom to be able to go to and fro, wherever one wants, and whenever they want. I think that this association is made subconsciously even if they don't actually exercise that liberty. To that end, I believe that people's problem with the range of EV's is less of an issue of actually needing a really large range on a daily basis and more an issue of having the freedom to drive almost anywhere they might want to on a spur of the moment, if they should so choose.

I, for one, refuse to buy an electric vehicle until it has a range of 1000 miles on a single charge, and can be fully recharged in under 30 seconds. Anything less is completely impractical. I also want 12 cup holders. When they achieve this performance level, I will find another rediculous excuse not to buy one.
And I will continue to insist on my god given right to mis-spell rediculous.
"Electric engines are roughly 3-4 times as efficient as gasoline ones. So you get 3-4 times the effective energy density out of batteries."
Sure, but who wants to buy a car that only gets 100 miles, then needs to be recharged every 50 miles? This might be a good second or third car, but it's not that practical as your main vehicle, and the fact that an electric vehicle must be charged nightly limits it to only being useful to homes with garages.
This is why SUVs have been so popular in the US despite their poor gas mileage. You can fit 5 to 7 adults comfortably and still have room for luggage.
Electric cars will fail, and series hybrids like the Chevy Volt will succeed. When the batteries run low a gas generator keeps the batteries charged enough to power the vehicle. This is brilliant: I get my electric car for my short daily commutes, but I still have gas for those rare times when I need to drive hundreds of miles in a day. I have the best of both worlds with no sacrifices.
Also series hybrids means we can finally use turbines: gas turbines are the most efficient engine. While a gasoline engine is only 20-30% efficient, a gas turbine is over 80% efficient. In 1999 GM made a EV1 Series hybrid using a turbine generator. The vehicle achieved up to 100mpg while charging the battery using 90s technology and a 220 lbs turbine (modern turbines are much smaller)
In ten years when series hybrids become the norm we'll look at vehicles like the Prius the same way Prius owners look at SUV owners today.

The correct answer is actually hydroelectric power from Hokkaido. There is some nuclear power available though, and with enough warning it can be ramped up to full capacity for quite a while to provide even more.
It makes perfect sense in the 1970s and may do again - electricity available if there is a naval blockade by China. Expensive, high maintainance, awkward waste problems but ultimately it works in that situation. That's the sort of niche nuclear advocates should be arguing for and improving to turn it from the expensive alternative energy everyone hates into a commercial reality.

I imagine they're also very efficient at annoying the neighbors with the noise.
