To dump that much electricity into the capacitor in that short of time I’m thinking you need a pretty robust source and wire.
Another question.
If seen some significant damage when a cap fails, or when shorted. Especially in old TV’s. What happens when the giant one in your car fails?
They find your head in the back seat, or find a black husk that appears to have been struck by lightning?
I’d have to be convinced of stability, and overcharge barriers in something that can store that much power, that quickly.
“To dump that much electricity into the capacitor in that short of time I’m thinking you need a pretty robust source and wire.”
No doubt. But, robust sources and fat wire exist and are widely used. Thus, this is a feasibility, assuming the articles claims are true. Conventional Ni-CD and Li-ion batteries simply cannot accept too much charge at a time or they heat up destructively and/or blow up.
Dr Watson, by jove you got it!
100 miles worth of battery charged in 4 minutes?
In other words 2 hours to 4 minutes ratio? = 30
In other words the power required to charge the battery will be 30 times that of the electric motor. If the motor is running on 15 amperes and 24 volts,
the charger would need to push 15 x 30 x 24 / 110 = 98 amps at 110 volts, assuming 100% charger efficiency.
That is a lot of juice....will need might big power cables.
The S. Korean is working on miniature size capacitors.
Expanding that to real world needs is another thing.
I would not buy stock in any outfit dreaming of this.
