basically the technique involves pulsing the current during (dis)charging, and optimising the length and timing of the pulsing in real-time, because the optimal settings change through the life of the battery.
I'm kind of a battery nut. I've been building various pulse chargers and capacitive current limiting chargers for years. Without fail all of my most promising pulse charge/bleed schemes that yielded faster charges and greater runtimes have done so at the expense of cycle numbers. Usually by a factor of 10 or more. I hope they've outsmarted this, but I have my doubts.
