LM25143: DC to DC Charger Solution

Part Number: LM25143
Other Parts Discussed in Thread: LM5148-Q1, LM5143

We use Adaptor to charge battery(built in BMS).

Adaptor Voltage is 32V or 36V,battery voltage is 25.2V. Charging Current is 7A max.

We want to use buck controller to connect Adaptor and Battery,through control FB to adjust current and voltage.

But thermal is a problem. Is this solution OK?

And please recommend other solutions to charge battery.
