since u are working battery charging circuit i would suggest you to go for charge pump circuits.....these charge pump circuits will generate voltage larger than the input supply.............there are diff types of charge pumps viz. dickson charge pump using mosfets.....cts charge pumps....cascoded charge pumps......if u have doubts contact me ......

What if the input supply is already more than the battery voltage? Say, 240Vac input for a 1.5V rechargeable cell?

This is why I say all designs begin with specifications!
