Vishal - 

We don't have any off-the-shelf reference designs for battery chargers of this power level.  However, you can  use an existing RDK/DER as a starting point and then use the CV/CC feedback topologies in the attached design note to implement the CC function you'd need in a battery charger.

For some of the more advanced battery charger features (different charge rates, elevated voltage cycling, etc) you'll likely need to use some additional controller IC specifically for use with charging high-power batteries.
