Chimera does its own charge estimation, based on the atom types it’s computed for the ligand. The routine is called estimateNetCharge and it’s found in the AddCharge module in your Chimera distribution. It’s a fairly complicated routine.
Specifically the file you will find estimateNetCharge in is:
<Chimera install location>/share/AddCharge/__init__.py
