    Fast charge car batteries!

    New EV Battery Can Charge in 10 Minutes
    This is an interesting development, I wonder if they can do it without compromising the battery life,
    or worse catching the car on fire.
    There is also a trick or getting 75 Kwh of energy transferred in 10 minuets.

    Pfft. Advertising. They still won't be able to self-conflagrate as fast as my good ol' Tesla. nonono.gif

    LOL heat them up to burning point and then cool them down quickly? I can imagine all sorts of fires occurring throughout the neighborhood if this comes into widespread use.

    The car would be a very good Christmas gift for Greta.

    Why? plenty of CO2 emissions go into making a Tesla!

    Oh that's right. Maybe this?

    140 degrees isn't "burning" and 140 degrees is a rather magical temperature zone because a lot of other things happen between 140 and 175 degrees. At 165 degrees, most if not all food borne microbes, bacteria and parasites die and meats are rendered safe for consumption.
    At 140 degrees, magnetic tape mylar backing and the oxide that stores the magnetic information become pliable enough that a damaged tape with oxide shedding problems will suddenly play faithfully enough that it can be backed up as a digital copy for preservation.

    And in the case of Li-Ion batteries, which I've used as a camera operator ever since they first were invented, 140 degrees is exactly what a lot of "smart chargers" actually do, although they lack the ability to cool the batteries down "quickly" and that is because a camera battery will cool down quickly enough by itself if adequate ventilation is available.

    In fact, I have a very small smart charger which charges up individual commercial grade Li-Ion cells eight at a time.
    It is a closed door unit, meaning that the cells sit inside the compartment while charging, a computer controlled FAN vents the compartment once the cells reach a certain temperature, unsurprisingly that temperature is about 140 degrees give or take a few.
    The fan kicks on and the cells cool rapidly. It is a RAPID CHARGER made by Tenergy, who also makes the cells I use.

    What the techies at Penn State have done is remarkable, but not because it is a new approach.
    It's certainly a new approach in AUTOMOTIVE battery pack charge management but it is not entirely new.
    I suspect what's new is the idea of RAPID COOLING, because with a giant car battery pack, that takes much more than just a little fan.

    Electric cars is getting better and better lifespan.

    Also that the average commute is less than ten percent of battery capacity in modern electric cars. So most days electric cars can be slow charged while at work or home at night, there it also don't need to be done everyday. While for road trips it can often be good to combine charging the car with for example eating at restaurant. So the big benefits of 10 minutes charge is more psychological to deal with range anxiety for the average driver. While a ten minute charge can of be very good in edge cases and also can increase the potential for trucks.
