I suspect it is has lots of smaller batteries rather than a few large ones. That means that during a quick charge, many(all?) of them are connected in series, to allow charging at a very high voltage. Since they quote 10-15 thousand volts, and a single cell is about 1.5 volt, I would say about 10,000 cells in series (with possibly two or more of these banks in parallel?) At 10-15 thousand volts a current of 100 A would suffice, and they say that the special cathode (nano-powder?) allows for high charging currents.
