It is not that hard of a problem. Supply 1k volts and your good for quick charge.
Each cell can charge in parallel. Divide the voltage and send it to each cell.

Please understand that in electronics lingo, "in parallel" doesn't mean "concurrently" as it does in the computer world. Connecting all the LEAF's cells in parallel and then quick-charging them would call for a "simple" collection of electronic switches capable of handling currents on the order of 250A, two per cell, to reconfigure the battery from an all-in-series configuration to an all-in-parallel one, and then coming up with about a four volt, twenty-five THOUSAND amp power supply to charge them. And to what purpose?
