Does cell smoothing actually work to increase EV range?

[JonW]

Does anyone have experience using the cell smoothing process for the drive battery and how much increase in range resulted? Done at dealer or at home? I recall seeing someone post instructions for how to do this at home, but cannot seem to find those. Would be grateful for any ways to increase range of my 2018 PHEV GT or know of anything that Mitsubishi is doing for owners with reduced EV range. Thanks!
