That is a two thousand two hundred watt power supply. Are you able to build such a thing? What is this for, and what is your skill set for such a large project?
Even a 56V 10A charger is not a trivial project. Have you considered how you will achieve charge balancing of the individual cells making up the battery? What is the battery chemistry?
Actually a NiMh cell has a nominal voltage of 1.2V, so your basic unit would be a 6S cell-pack.
You would need 8 packs to make up your 56V. To charge them safely, each pack's voltage and temperature would need to be monitored.
ICs are available for controlling safe charging of cells in series, but I don't know of any designed to handle 8 packs making up a 56V battery. Other members here may be aware of some.

yes correct each cell is of 7.2 volt and 6.5 amp now my question is can you tell me how much voltage charger is require to charge it fully but not harm it. and as its capacity is 6.5 amp so how much maximum amp can i give it maximum.
No. Each cell is 1.2V. The cell-pack (battery) is 7.2V. There;s no such animal as a 6.5A battery. Do you mean 6.5 AmpereHours (Ah)? What is the rated maximum charging current for your cell-pack (this is not the same thing as the Ah capacity)?
