Hi All,

I am designing a switching battery charger based on boost converter using averaged current-mode control approach for charging a Li-Ion rechargeable battery.

For this purpose, I need a suitable small-signal model for the battery to be used in my hand-analysis as well as in simulation for estimating the various transfer functions of the converter considering the load characteristic.

Is there anyone who can suggest me some suitable model to be used in my analysis.
