More comments about the viability of ultra-fast charging batteries.
I also comment on the feasibility of replacing the batteries of ultra-high-load. If you have something to say small battery, an amp-hours and want to take in a minute, how many amps do you need? That is, the demons of mathematics, 60 amps. So the battery can be charged quickly, but you need a charger to be $ 300. Of course, this short two minutes up to 30 amps, and cuts fourth minute is 15 amps, etc.
Then we must also take terminals, cables, connectors that can handle 60 amps and you may have what looks like a Miata a semi tractor, semi-finals are the cables and the Miata is the battery.
We must also consider the characteristics of the battery. The lithium-ion cells require a constant voltage algorithm constant current. The amount of current can be dumped into the cell is limited by the requirement of chemistry to maintain the load voltage below 4.2 volts. It is conceivable that you can get 80% of the load cell in the first minute, but for the remaining 20% would be 59 minutes.
Of course there are some applications that justify the equipment needed to charge a battery in 60 seconds. But it's not laptops or cell phones.
