If it can see the charge current (just because it is displayed does not mean that it knows the quantity..perhaps that is a different chip) then it can be implemented with a new program.. the PIC cpu would have to have two A/D converters.. one for the important voltage and one for the current. Anyone knows what model PIC is used?.. also assuming there is enough room for the new program.
