i am still missing WHY you need to recharge in less then 15 minutes after consuming ~1kWh of energy. it would seem that increasing the battery size would decrease the need for such a charging need.
160A does not change the metrics (or imperial
) any better in practical terms. the wires get a bit thinner and you can scale 1 tier lower in your connectors but its still WAY too much. you still need pretty absurd cables, connectors and cell busbars.
especially if you run a 35mph scooter or whatever at the most. that does not even break 4~5kW in actual average consumption.
if you want to get 1~1.5kWh into a 24v battery in 15 min or less you will need to hit 250A accoriding to the charts if you include the taper off at the end.
a 72V battery (wich is still the standard for scooters) gets you about 55A for 1kWh in 15 minutes if you were to ignore the taper off. about 80A if you include it. those numbers are actually somewhat doable.
a battery like this at 24V range is simply not feasable or better said: affordable. its simply nonsensical to make such a battery in such a low voltage.
still, LTO is stupidly big compared to a regular lithium battery. you can fit 6x the capacity in the same volume. if you can store that much you dont need to charge so fast in the first place. hell, even china gave up on LTO for their eletric buses in favour or regular lithium cells....
if you want to fit the battery into a lot of vehicles you certianly need to consider size, you also aint getting far on 1kWh at 35mph on a scooter, you will drain that battery in 20 minutes....
The bitterness of low quality remains long after the sweetness of low price is forgotten
