would you want guesses or real answers 🙂
i could guess that a charger could have a pre-charge for a cell that was too low in voltage (flat) when put on the charger. the chemicals in a "flat" call can be not making such great "contact" (so to speak) and a slow light charge or pulse slow, could assist in forming the chemicals back into a more working state. prior to punching up to the real charge.
A pre-charge might also be a forming charge (or both) if somehow a charger could determine that it was in need of being formed , again to get things in the best state via the chemicals, slow charge and discharge the whole thing once from end to end.
A pre charge might be applied in the situation of a "high resistance" cell item, where a specific alogrythm would be best to shift oxidations, and such to attempt to improve the connections to the plates & electrolyte and all.
bad guesses from good people.
check the voltage before putting the cell item on, and that would give you a clue if it was flat. check the "resistance" via a simple "load and voltage" testing to see if the cell is suffering from high resistance.
Check the voltage of it on the cahrger while "Pre-charging". Look for pulses, look for voltage going down, look at the general voltage. that would give you a clue as to what is actually happening , vrses whatever name they applied to it.
a Pre-charge could also be a poorly worded discharge before charge, if the resistance was high, or the charger just discharges automagically before a charge, when it deems that a full cycle would help.

German manuel for energy plus model, says something about it, but i cant read german 🙂
Features say it will run a discharge (cycle) a battery it feels is in need of it.
