    Hello Daisy Yang

    The BQ2002T is very limited NiMH battery charger that requires an external current source to supply charge current.  The "T" version will look for a rise in battery temperature to indicate charge complete.  Additional load on the battery during charging will complicate detection.

    For a Li-Ion battery we have other options and the BQ24074 may work better in this type of application.
