At least as of the Habitat update, the swim charge fins do not recharge the Seaglide or (if you spawn it in) the Powerglide; they don't reduce energy usage, either. The reason can easily be seen by looking down at your feet, where you'd normally see the fins sparkling, while you equip either vehicle: when you're using the Seaglide or Powerglide, you don't actually kick your feet at all.

Further testing was done by checking Seaglide battery use over a fixed distance (doesn't change whether I use the charge fins, the regular fins, or no fins) and by swimming directly up and down with the Space / C keys (this doesn't activate the Seaglide propellor, and doesn't use any battery; it does recharge the hand tools that the charge fins normally affect, though.)
