Company Builds Fast Charging Station For Electric Cars

Posted by samzenpus on from the fast-as-lightning dept.

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."

    350*70=24.5 kW, not 240

    My Tesla Roadster launches off the line faster than any other exotic vehicle I've driven (including a Lamborghini Murcielago and the Ariel Atom). What does that? Torque, and lots of it. Electric motors have full torque from 0 rpms, unlike internal combustion engines that have a limited torque band (and hence, the need for inefficient transmissions).

    And regarding the snow? Yea, electric cars do just fine there:

    From TFA (close to the end):

    But for retail locations and gas stations, the 62.5 kW power requirements of each charger should not be impossible to accommodate in all but the remotest of locations.

    In addition, even the remotest location can accommodate it: just install a generator burning gas (I'm kidding but only half-kidding: remote locations in which you can currently refill your tank will have petrol and a generator will consume less per kWh generated than the car's petrol engine...be it only because it doesn't need to change gears/etc).

    ...16kWh battery pack of the Mitsubishi i-Miev...

    ...charging a 2011 Mistubishi i-Miev from empty to 50% full in just three minutes

    50% of 16kWh is 28800000J. 28800000J divided by 180 seconds (3 minutes) is 160000 J/s, or 160kW.

    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.
